Learn why network security policy management is crucial for insurance companies to safeguard sensitive data, ensure compliance, and mitigate cyber risks effectively. Why Insurance Companies Need Network Security Policy Management Opening Insurance institutions face two major network security related challenges while working to serve their customers: the constant demand to improve in order to successfully compete in the market, and regulatory compliance. Yet, when it comes to security, the InfoSec team often uses slow, manual (and error prone) processes to make the necessary network security changes – thereby delaying the release of a new competitive application or feature to market. To overcome these challenges, insurance institutions must implement a network security policy management solution Schedule a Demo Introduction In order to maintain a competitive advantage, information security teams at insurance companies must be able to support business transformation initiatives and deploy new applications or updated functionality to market quickly and securely. Most IT departments use automation tools to assist them with many aspects of their work – including managing software changes or provisioning storage. Automation allows them to support the fast pace required, ensure quality and maintain compliance with industry regulations. However, when it comes to security, oftentimes the InfoSec team still makes the necessary network security changes using manual processes. This is mostly due to the perceived complexity of the segmented network infrastructure; the large number of firewalls and network security devices (from multiple vendors) that are typically deployed across an insurance company’s network, as well as the extensive compliance requirements to which insurance companies are subjected. As a result, the InfoSec team is often perceived as a bottleneck to progress – holding back the release of a new competitive application or feature to market. This white paper discusses the challenges facing InfoSec teams today. It then explains how a network security management solution delivers critical automation that help transform the InfoSec team from a business inhibitor to a business enabler. Schedule a Demo Network security challenges for insurance companies Insurance companies face two key network security related challenges in their mission to serve their customers: regulatory compliance and a continual demand for changes in order to compete in the market. The number of regulations that insurance companies are required to uphold has significantly increased over the years. They include GLBA, GDPR, BASEL II, SOX, Dodd-Frank, PCI-DSS and many others. While these regulations aim to provide best practices that help both the insurance company and their customers, they require considerable effort to maintain, particularly with regards to network security. The second challenge that impacts network security, is the constant demand for changes. In recent years, the demand for innovation coupled with competition from agile and disruptive insurtech companies is putting considerable pressure on insurance companies. As a result, insurance companies are constantly seeking ways to improve the way they interact with their customers while becoming more efficient. This means that there is now an ever-present need for change in a typically conservative industry which has previously been slow and reluctant to embrace change! Managing network security changes efficiently and effectively across today’s complex network environments requires automation. Yet, while IT teams have embraced automation to handle many of their tasks, the InfoSec team has not. In the following section, we discuss ways to utilize automation to manage security changes and manage the ever-increasing demands of industry regulations. Schedule a Demo Automated network security policy management To tackle these challenges the InfoSec team need automation to effectively manage the demands of regulatory compliance as well as keep up with the volume of network security policy changes. Managing compliance with industry regulations As part of compliance requirements most regulations require full visibility into the security posture, regular audits, and documentation of any changes. Visibility of the security posture: The first step to achieving visibility is to identify all the applications that support customer transactions and manage customer information. The next step is to classify them based on the relevant regulations, such as PCI for applications that manage cardholder information. There are tools that can handle this process automatically, including the discovery process, which saves considerable time. Moreover, automation tools can help with documenting the entire environment, including the network security device configurations and security policies – which is a key part of regulatory compliance. In addition to supporting compliance requirements, this visibility and transparency exposes any gaps and risks in your network security, and thus helps to make your network secure. Streamlined audits: Whether internal or external, audits eat up considerable resources. The InfoSec team currently needs to spend significant time and effort generating reports that document their security posture and prove compliance with every regulation – time that could be better spent focusing on securing the network or responding to business requests. Automation can handle all these processes, and generate self-documenting, audit-ready reports out of the box. Documenting compliance: Most network security management solutions review all changes during design and deployment to ensure that they comply with the industry regulations. As part of this process they document and provide a full audit trail of the change, thereby automating the requirement for change documentation. Get a Demo Managing the constant barrage of change requests An automation solution is paramount for tackling the frequent change requests that are typically required in the insurance industry. An automation solution enables the InfoSec team to focus on the impact and risk of the change as well as ensure that all changes are necessary (typically around 30% of change requests are unnecessary). An automation solution must: Ensure that the network security policy change request will not breach the compliance posture Automatically map the network route for any planned changes and identify the firewall, routers and switches along that route that need to be changed Assess all the risks of a security change. These include regulatory compliance risks as well as internal risks Understand the details of each firewall rule change request and determine whether a change is really needed, whether a change to an existing rule will be sufficient or if there is a need to create a new rule as part of the change request. This process reduces the overall number of rules and helps optimize the security ruleset Be able to automatically deploy changes directly in firewalls Schedule a Demo Summary Insurance companies are constantly seeking to better serve their customers and maintain a competitive edge through new technology innovations. Yet they often fall behind on delivering these new innovations into production. Their network and security operations team are hampered by manual and error-prone security change management processes coupled with the ever-increasing demands of industry regulations, which impact time-to-market. Automated network security management solutions help streamline the auditing process and ensure continuous compliance as well as significantly simplify and speed up the process of managing network security changes.

Cloud-native organizations need an efficient and automated way to identify the security risks across their cloud infrastructure. Sergei... Cloud Security CSPM essentials – what you need to know? Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/24/22 Published Cloud-native organizations need an efficient and automated way to identify the security risks across their cloud infrastructure. Sergei Shevchenko, Prevasio’s Co-Founder & CTO breaks down the essence of a CSPM and explains how CSPM platforms enable organizations to improve their cloud security posture and prevent future attacks on their cloud workloads and applications. In 2019, Gartner recommended that enterprise security and risk management leaders should invest in CSPM tools to “proactively and reactively identify and remediate these risks”. By “these”, Gartner meant the risks of successful cyberattacks and data breaches due to “misconfiguration, mismanagement, and mistakes” in the cloud. So how can you detect these intruders now and prevent them from entering your cloud environment in future? Cloud Security Posture Management is one highly effective way but is often misunderstood. Cloud Security: A real-world analogy There are many solid reasons for organizations to move to the cloud. Migrating from a legacy, on-premises infrastructure to a cloud-native infrastructure can lower IT costs and help make teams more agile. Moreover, cloud environments are more flexible and scalable than on-prem environments, which helps to enhance business resilience and prepares the organization for long-term opportunities and challenges. That said, if your production environment is in the cloud, it is also prone to misconfiguration errors, which opens the firm to all kinds of security threats and risks. Think of this environment as a building whose physical security is your chief concern. If there are gaps in this security, for example, a window that doesn’t close all the way or a lock that doesn’t work properly, you will try to fix them on priority in order to prevent unauthorized or malicious actors from accessing the building. But since this building is in the cloud, many older security mechanisms will not work for you. Thus, simply covering a hypothetical window or installing an additional hypothetical lock cannot guarantee that an intruder won’t ever enter your cloud environment. This intruder, who may be a competitor, enemy spy agency, hacktivist, or anyone with nefarious intentions, may try to access your business-critical services or sensitive data. They may also try to persist inside your environment for weeks or months in order to maintain access to your cloud systems or applications. Old-fashioned security measures cannot keep these bad guys out. They also cannot prevent malicious outsiders or worse, insiders from cryptojacking your cloud resources and causing performance problems in your production environment. What a CSPM is The main purpose of a CSPM is to help organizations minimize risk by providing cloud security automation, ensuring multi-cloud environments remain secure as they grow in scale and complexity. But, as organizations reach scale and add more complexity to their multi- cloud cloud environment, how can CSPMs help companies minimize such risks and better protect their cloud environments? Think of a CSPM as a building inspector who visits the building regularly (say, every day, or several times a day) to inspect its doors, windows, and locks. He may also identify weaknesses in these elements and produce a report detailing the gaps. The best, most experienced inspectors will also provide recommendations on how you can resolve these security issues in the fastest possible time. Similar to the role of a building inspector, CSPM provides organizations with the tools they need to secure your multi-cloud environment efficiently in a way that scales more readily than manual processes as your cloud deployments grow. Here are some CSPM key benefits: Efficient early detection: A CSPM tool allows you to automatically and continuously monitor your cloud environment. It will scan your cloud production environment to detect misconfiguration errors, raise alerts, and even predict where these errors may appear next. Responsive risk remediation: With a CSPM in your cloud security stack, you can also automatically remediate security risks and hidden threats, thus shortening remediation timelines and protecting your cloud environment from threat actors. Consistent compliance monitoring: CSPMs also support automated compliance monitoring, meaning they continuously review your environment for adherence to compliance policies. If they detect drift (non-compliance), appropriate corrective actions will be initiated automatically. What a CSPM is not Using the inspector analogy, it’s important to keep in mind that a CSPM can only act as an observer, not a doer. Thus, it will only assess the building’s security environment and call out its weakness. It won’t actually make any changes himself, say, by doing intrusive testing. Even so, a CSPM can help you prevent 80% of misconfiguration-related intrusions into your cloud environment. What about the remaining 20%? For this, you need a CSPM that offers something container scanning. Why you need an agentless CSPM across your multi-cloud environment If your network is spread over a multi-cloud environment, an agentless CSPM solution should be your optimal solution. Here are three main reasons in support of this claim: 1. Closing misconfiguration gaps: It is especially applicable if you’re looking to eliminate misconfigurations across all your cloud accounts, services, and assets. 2. Ensuring continuous compliance: It also detects compliance problems related to three important standards: HIPAA, PCI DSS, and CIS. All three are strict standards with very specific requirements for security and data privacy. In addition, it can detect compliance drift from the perspectives of all three standards, thus giving you the peace of mind that your multi-cloud environment remains consistently compliant. 3. Comprehensive container scanning: An agentless CSPM can scan container environments to uncover hidden backdoors. Through dynamic behavior analyses, it can detect new threats and supply chain attack risks in cloud containers. It also performs container security static analyses to detect vulnerabilities and malware, thus providing a deep cloud scan – that too in just a few minutes. Why Prevasio is your ultimate agentless CSPM solution Multipurpose: Prevasio combines the power of a traditional CSPM with regular vulnerability assessments and anti-malware scans for your cloud environment and containers. It also provides a prioritized risk list according to CIS benchmarks, so you can focus on the most critical risks and act quickly to adequately protect your most valuable cloud assets.

Leading Life Insurance Company Ensures Security and Compliance Organization Life Insurance Industry Financial Services Headquarters Texas, USA Download case study Share Customer
success stories "AlgoSec worked right out of the box. We got started quickly and never looked back.” A leading insurance provider of life, disability and other benefits for individuals increases efficiency and ensures continuous compliance on their networks. Background This life insurance company provides insurance and wealth-management products and services to millions of Americans. The company employs thousands of people and maintains a network of several thousand financial representatives. They offer a wide range of insurance products and services that include life insurance, disability income insurance, annuities, investments, dental and vision. Challenges For decades, the company operated a large and growing data center in Bethlehem, PA which they recently transferred to Dallas, TX. During and since the transfer, the company has been replacing much of its multi-vendor network infrastructure, consolidating on Cisco Firepower technology, but still maintaining vestiges of other routers, firewalls and network equipment. At the new data center, the company’s IT staff maintains more than 100 firewalls that host some 10,000 rules. The company’s network security engineer described the considerable pressure on the security staff: “Change requests are frequent, 25-30 per week, demanding considerable time and effort by the security team.” Due to the presence of firewalls from multiple vendors, change requests were analyzed manually and pushed to devices with great care so as not to interrupt the operation of a rapidly growing body of applications. “The change–request process was tedious and very time consuming,” declared the engineer. “as was the pressure to maintain a strong compliance posture at all times.” The company is subject to a litany of demanding insurance-industry regulations that concern the care of personal information and processes. Managing risk is critical to the success of the business and being able to ascertain compliance with regulations is always vital. Solution The security team turned to AlgoSec to help them manage network security policy across the large data center that includes firewalls from multiple vendors. After a careful review, the security team acquired AlgoSec’s Firewall Analyzer to speed up the process of firewall change management as well as to continuously quantify the degree of compliance and level of risk. Vendor-agnostic AlgoSec Firewall Analyzer delivers visibility and analysis of complex network security policies across on–premise and cloud networks. It automates and simplifies security operations including troubleshooting, auditing and risk analysis. Firewall Analyzer optimizes the configuration of firewalls, routers, web proxies and related network infrastructure to ensure security and compliance. Results After a very short installation and learning period, the security staff became proficient at operating Firewall Analyzer’s helpful capabilities. Soon thereafter, staff members undertook AlgoSec certification courses to become experts in using the solution for firewall analysis. “AlgoSec worked right out of the box,” said the engineer. “We got started quickly and never looked back.” The AlgoSec solution has significantly improved processes, delivering significantly improved results for their security team: Reduced time to analyze and optimize firewall rules, automatically checking for shadow rules and discovering other rules eligible for consolidation or deletion. Continual optimization of firewall rules across their entire network estate. Increased efficiency of security staff, enabling them to keep up with the volume of change requests. Accelerated and more accurate change verification. Audit-readiness, generating scheduled and on-demand compliance reports. The security staff looks forward to implementing AlgoSec FireFlow (AFF), that will enable them to push changes automatically to their population of firewalls, eliminating errors and further reducing risk. With AFF, the staff will be able to respond to changing business requirements with increased speed and agility. They added: “We are also checking out AlgoSec’s new cloud-security solution since we are migrating a growing number of applications to AWS.” Schedule time with one of our experts

Learn how firewall rules secure your network from cyber threats. Explore types, best practices, and management strategies to optimize your firewall security. Firewall rules & requirements (inbound vs. outbound) How to secure your network from threats? The cybersecurity landscape is increasingly volatile, with a massive rise in cyberattacks. Malicious cyber actors are relentlessly scouring the internet for vulnerable networks. Any company that wants to keep its network secure must implement a network security solution – a firewall. Cyber attackers keep evolving and finding ways to compromise security systems. As a result, companies need to implement and maintain security best practices. Installing a firewall is not enough; you have to take a step further to ensure the firewall rules are up-to-date and properly managed. If you want to learn how firewall rules work and secure your network from threats, keep reading! This article covers everything you need to know, including types of firewall rules, examples of firewall rules, and firewall rule best practices. Schedule a Demo What are firewall rules? Firewall rules are the major components of firewall policies that determine which types of traffic your firewall allows in and out of your network, and which are blocked. They are access control mechanisms that firewalls use to protect your network from being infiltrated by malicious or unauthorized traffic. Firewall rules examine the control information in individual packets, and either block or allow them based on a set of rules or predetermined criteria. These predetermined criteria or rule components include a source IP address, a destination IP address, ports, protocol type (TCP, UDP, or ICMP), and services. Firewall rules control how the firewalls prevent malicious programs and unauthorized traffic from compromising your network. So properly managing your firewall rules across your infrastructures is instrumental to securing your network from threats. Schedule a Demo How do firewall rules work? A firewall examines each incoming and outgoing data packet and matches it against the firewall rules. A packet is allowed to go through to its destination if it matches one of the rules that allow traffic. If a packet matches none of the rulesor hit a rule with deny, it is rejected. The rejection or mismatch is reported if the firewall is configured to do so. Firewalls are programmed to work with access control lists (ACLs). ACLs contain lists of permissions that determine network traffic that is allowed or blocked. An access control list details the conditions a data packet must meet before the ACL action (allow, deny, or reject) can be executed. To help you understand how firewall rules work, here’s a practical example: if a firewall rule states that traffic to destination N should be allowed only if it is from IP address M, the firewall will check the packet source and destination of incoming packets, and allow packets that meet the M & N rule to go through. If its packet’s destination is N but its source is unidentified or different from M, it is blocked. Packets are checked against firewall rules from top to bottom, and the first rule that matches the packet overrides the other rules below. The last rule is Deny Rest. This means that all packets not expressly permitted by the rules are blocked. You can create a firewall rule in pfSense. pfSense is an open-source firewall and router with unified threat management, load balancing, multi-WAN, a DNS Resolver, and a VPN. It supports a wide range of network technologies, including IPv4 & IPv6 addresses and pfBlockerNG. Other firewalls you can use to create firewall rules include Zenarmor, Windows Defender, and iptables. Schedule a Demo Why are firewall rules important? Firewall rules help network administrators to regulate access to networks. With firewall rules, you can determine what is allowed in and out of your network. For example, they prevent dangerous files like worms and viruses from accessing your network and consuming bandwidth. When it comes to protecting devices that operate within your network, firewall rules establish an essential line of defense. Firewalls (and other security measures like endpoint protection and security certifications) prevent malicious actors from accessing and compromising devices connected to your network or operating inside your network’s environment. Firewall rules help you comply with regulatory standards. Depending on your industry, relevant regulatory agencies expect your company to maintain a certain level of security. For example, if your business is located in the EU region or collects personal data of EU citizens, it is mandated to comply with GDPR. Schedule a Demo What are the main types of firewall rules? There are various types of firewall rules. They are categorized based on the type of security architecture under consideration. That being said, here are some of the major types of firewall rules: 1. Access rule As the name implies, this firewall rule blocks or grants access to inbound and outbound traffic based on certain conditions. The source address, destination address, port number, and protocol are key information that the access rule evaluates to determine whether access should be given or denied. 2. Network address translation (NAT) rule NAT helps you hide the original IP address of a private network – enabling you to protect your network. It makes traffic routing easier and smoothens the inflow & outflow of traffic to and from your network. 3. Application level gateways This type of firewall rule enables network administrators to implement policies that protect your internal network. Application-level gateways function as shields or gatekeepers between your internal network and the public internet. Administrators use them to regulate access to public networks, block some sites, limit access to certain content, and regulate devices allowed to access your network. 4. Stateful packet filtering This rule evaluates data packets and filters them against preset conditions. The traffic is denied access if it fails to meet the requirements outlined by the predetermined security criteria. 5. Circle-level gateways Circle-level gateways do not filter individual packets but rather monitor TCP handshakes to determine whether a session is legitimate and the remote system is considered trusted. Consequently, these gateways provide anonymity to your internal network. Schedule a Demo What is an example of a firewall rule? Firewall rules frequently consist of a source address, source port, destination address, destination port, and an action that determines whether to Allow or Deny the packet. In the following firewall ruleset example, the firewall is never directly accessed from the public network. This is because hackers who can directly access the firewall, can modify or delete rules and allow unwanted travel. Source addressSource portDestination addressDestination portAction AnyAny10.10.10.1AnyDenyAnyAny10.10.10.2AnyDeny10.10.10.1AnyAnyAnyDeny10.10.10.2AnyAnyAnyDeny In the following firewall ruleset example, all traffic from the trusted network is allowed out. This ruleset should be placed below the ruleset above. Since firewall rules are checked from top to bottom, specific rules should be placed before rules that are more general. Source addressSource portDestination addressDestination portAction 10.10.10.0AnyAnyAnyAllow Schedule a Demo What are the best ways to manage firewall rules? Effective management of firewall rules is necessary to avoid conflicting configurations and ensure your security infrastructure is powerful enough to ward off malicious attacks. To manage firewall rules better, do the following: ● Maintain proper documentation Properly document policies, rules, and workflows. It’s difficult for your network administrators to stay organized and manage firewall rules without proper documentation. Implement a strict documentation policy that mandates administrators to document policies and configuration changes. This improves visibility and ensures seamless continuity even if a key network operator leaves the company. ● Assign tasks with caution Ensure that only well-trained network operators have the privilege to assign and alter firewall rules. Allowing everyone on your security team to assign and change firewall rules increases the chances of misconfiguration. Giving such a privilege to a select few does the opposite and makes containing mismanagement easier. ● Use a standardized naming convention It’s easy to get confused about which configuration does what. This is more likely to happen where there is no naming convention. To avoid conflicting configurations, name each rule to clarify its purpose. By clearly defining the rules, conflicts can be easily resolved. ● Flag temporary rules Some rules are created to function just for a while – temporary rules. To keep things simple and ‘neat,’ flag temporary rules so they can be eliminated when they are no longer required. ● Order your rules Order rules in a specific pattern. For example, begin with global rules and narrow down to user-specific rules. ● Use a firewall management solution Many administrators use a firewall management and orchestration solution to streamline the firewall rule management process. The solution integrates with your firewall and uses built-in automation for managing firewall settings and configurations from a single dashboard. A firewall management tool helps you automate activities, gain visibility on all firewall rules, optimize firewall rules, remove rule anomalies, generate reports, etc. Schedule a Demo What are the best practices for firewall rules? To ensure your firewall works properly and offers the best security possible, there are some key best practices you have to follow when configuring and managing firewall rules: Review the firewall rules regularly The cyber threat landscape is always changing. Therefore, you must regularly review the firewall rules to ensure they provide optimal security against threats. Reviewing firewall rules helps you to be several steps ahead of malicious cyber actors, remove rule anomalies, and maintain compliance. Cyber attackers are relentlessly devising new ways to compromise security systems, infiltrate networks & subnets, and wreak havoc. You need to update the firewall rules regularly to counter new attacks. Obsolete rules can be maneuvered and the firewall compromised. You have to keep evolving the rules to stay ahead of malicious actors. Remove ineffective, redundant firewall rules. Are there rules that are no longer needed? Are there overlapping rules that are taking up space and confusing your network administrators? Look out for unnecessary configurations and remove them to free up the system and avoid confusion. In addition to helping you keep your network safe, reviewing firewall rules regularly also allows you to maintain compliance with regulatory standards such as HIPAA and GDPR. Keep tabs on firewall logs Keeping an eye on the firewall log helps administrators to monitor traffic flow, identify suspicious activities, and proactively fix challenges. Monitoring firewall logs gives you visibility into your infrastructure, enabling you to get to know your network users and the nature of their activities. Reduce complexity by categorizing firewall rules Make firewall rule structure simple and easy to manage by grouping rules with similar characteristics. This approach reduces configuration complexity, improves ease of administration, and optimizes firewall performance. Implement least-privileged access Do not grant users more privileges than necessary to perform their tasks. This ensures that only an authorized user can create a new rule, change a security policy, or gain access to specific resources. Block high-risk ports Blocking some ports can significantly decrease the risk of a network breach. The following table outlines the ports you should block as recommended by the SANS Institute .

success stories "AlgoSec has saved us a lot of time in managing our rule base.” Large energy supplier empowers internal stakeholders and streamlines network security policy change process Background The company is the provider of electricity and gas for their country. They are responsible for the planning, construction, operation, maintenance and global technical management of both these grids and associated infrastructures. The Challenge In order to provide power to millions of people, the company runs more than twenty IT and OT firewalls from multiple vendors that are hosted in multiple data centers throughout the country. Some of the challenges included: Lack of visibility over a complex architecture – With multiple networks, IT managers needed to know which network is behind which firewall and connect traffic flows to firewall rules. Change management processes were being managed by network diagrams created in Microsoft Visio and Microsoft Excel spreadsheets – tools that were not designed for network security policy management. Thousands of rules – Each firewall may have thousands of rules each. Many of these rules are unneeded and introduce unnecessary risk. Managing the maze of rules was time consuming and took time away from other strategic initiatives. Unnecessary requests – Business stakeholders were requesting status information about network traffic and making duplicate and unnecessary change requests for items covered by existing rules. The Solution The company was searching for a solution that provided: Visibility into their network topology, including traffic flows. Optimization of their firewall rules. Alerts before time-based rules expire. Automatic implementation of their rule base onto their firewall devices. They implemented AlgoSec Firewall Analyzer and AlgoSec FireFlow, as well as AlgoBot, AlgoSec’s ChatOps solution. AlgoSec Firewall Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec FireFlow improves security and saves security staffs’ time by automating the entire security policy change process, eliminating manual errors, and reducing risk. AlgoBot is an intelligent chatbot that handles network security policy management tasks. AlgoBot answers business user’s questions, submitted in plain English, and automatically assists with security policy change management processes – without requiring manual inputs or additional research. The Results Some of the ways the company benefitted from using AlgoSec include: Visibility and topology mapping – They are able to get a picture of their entire network and view traffic flows to each network device. Optimized firewall rules – They are able to adjust the placement of their rules, placing their most used rules higher in the rule base, improving performance, and also checking for unused objects or rules to clean up, removing unused rules, improving firewall performance. Improved communication and transparency for time-based rules – Before time-based rules expire (rule with an expiration date), the requester is automatically notified and asked if the rule should be extended or removed. Better, more refined rule requests – By first gathering information from AlgoBot, rule requests are better focused. Internal customers are able to check if rules are already in place before making requests, therefore avoiding requests that are already covered by existing rules. Empower internal stakeholders – Able to save the IT team’s time by empowering internal stakeholders to use AlgoBot to get the answers themselves to traffic queries. Met change implementation SLAs – By implementing their rules with AlgoSec, the company meets their internal SLAs for change implementation. Streamlined auditing processes – By documenting the changes they made in the firewalls, who made them, and when, their audit processes are streamlined. Zero-touch automation – Automatically implementing rules in multiple firewalls simultaneously ensures policy consistency across multiple devices, while preserving staff resources. This also eliminates the need to use the management consoles from individual vendors, saving time and reducing misconfigurations. Staff efficiencies – Hundreds of monthly change requests are able to be managed by a single staff member. He would not be able to do it without AlgoSec. The company switched from a competing solution because it was more user-friendly and provided greater visibility than the competing solution they were previously using. They are also impressed with AlgoSec’s scalability. “The initial setup is really easy. It has been running flawlessly since installation. Even upgrades are pretty straightforward and have never given us problems,” they noted. Schedule time with one of our experts
