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 Horizon Security Analyzer and AlgoSec Horizon FireFlow, as well as AlgoBot, AlgoSec’s ChatOps solution. AlgoSec Horizon Security Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec Horizon 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

Tags Share this article 4/6/26 Published As we close out the first quarter of 2026, I find myself reflecting on a start to the year that was defined by product momentum, stronger market validation, growing trust from regulated organizations, and meaningful industry recognition. In just three months , AlgoSec introduced important platform enhancements, published fresh research on where network security is heading, strengthened its standing with government and highly regulated customers, and closed the quarter with three major awards. More importantly, Q1 reinforced something we believe strongly: the market is moving toward security that is more application-centric, more automated, and more aligned with business reality. January – Removing friction across hybrid and multi-cloud security We opened the year with the release of A33.20, a meaningful step forward for the AlgoSec Horizon platform. The focus of this release was practical and timely: help security teams move faster without losing visibility, control, or confidence. As hybrid environments continue to grow more complex, policy changes are happening under tighter timelines and with higher business stakes. A33.20 was built to reduce that friction by simplifying workflows , improving visibility across AWS, Azure, Google Cloud, and Palo Alto Networks environments , automating more of the change process, and evaluating risk and compliance in the context of enterprise applications rather than as disconnected technical issues. What stood out most to me about this release was not just the feature list, but the direction behind it. Security teams do not need more noise. They need better context, clearer prioritization, and safer execution. With A33.20, we kept pushing toward a model where security policy management becomes more intelligent, more business-aware, and far less dependent on manual, error-prone work. That is the standard modern enterprises are increasingly demanding, and it set the tone for our quarter. February – Turning market insight and trust into momentum In February, we released the 2026 State of Network Security Report , and the findings made one thing very clear: the market is entering a new phase. Based on more than 500 responses across 28 countries, the report showed that organizations are looking for consolidation, unification, automation, and control as they navigate rapid cloud expansion, distributed workloads, and AI-driven traffic patterns. It also showed how quickly the environment is changing: 65% of respondents said they had already adjusted their strategies in response to AI-powered attacks, and 54.7% said security capabilities are now the most important factor when selecting a cloud platform. That market shift was reflected in our own momentum. In February, AlgoSec reported its best year ever , with gross dollar retention above 90%, 37% year-over-year new business growth in 2025, and more than 100 customers implementing the Horizon platform within months of its launch . March – Three awards that told one bigger story March brought a level of external validation that made the quarter feel complete. First, the 2026 Globee Awards for Cybersecurity named AlgoSec Horizon the Gold winner and Best of Category for Risk and Policy Management Solution . For us, that recognition validated the value of helping customers cut through fragmented environments with unified visibility across cloud and on-prem networks, automate policy management safely, and prioritize remediation in the context of real business applications. That recognition was followed by Cyber Defense Magazine’s 2026 Global InfoSec Award for Trailblazing AI-Powered Cybersecurity Solutions , published as part of its RSAC/March 2026 issue. This award mattered for a different but equally important reason. It reinforced that our AI strategy is not about adding another feature or another layer of alerts. It is about changing how security is managed: using AI to understand applications, prioritize risk based on business impact, and help teams implement the right policies across multi-cloud and on-prem environments. The capabilities highlighted internally — Horizon AppViz , AI risk prioritization, Intelligent Policy, and the Algo AI Assistant — reflect that broader shift from reactive security operations to intelligent, application-aware automation. Then came the 2026 SC Award for Best Risk/Policy Management Solution . What I especially appreciate about this recognition is that it reinforced the completeness of the platform story. SC Media highlighted AlgoSec’s application-centric approach across virtual, cloud, and physical environments, with a judge’s emphasis on the clarity of the overall offering and its fit for the enterprise environment. Together with the Globee recognition , the SC Award strengthened the message that risk and policy management today must be tied to application context, business impact, and real operational execution, not just rule sprawl or isolated controls. Taken together, these three awards told one bigger story about who we are and where the market is heading. Two awards validated our strength in risk and policy management. One validated our leadership in AI-powered cybersecurity innovation. All three pointed to the same underlying differentiation: AlgoSec does not treat applications, risk, and policy as separate problems. We connect them in one platform, helping organizations gain visibility, reduce manual effort, accelerate delivery, and maintain continuous compliance across hybrid environments. Looking ahead If Q1 is any indication, 2026 will be a year defined by consolidation . Security teams are being asked to move faster, manage more complexity, and prove business value more clearly than ever before . Our responsibility is to help them do exactly that with better visibility, smarter automation, stronger compliance, and a security model built around how applications actually work. That is the direction we have been building toward, and Q1 gave us strong proof that it is the right one. We are proud of how the year has begun, but even more energized by what comes next. The momentum from this quarter gives us a strong foundation for the rest of 2026, and we remain focused on helping enterprises simplify security management, reduce risk, and secure application connectivity without slowing the business down.

Explore Algosec's customer success stories to see how organizations worldwide improve security, compliance, and efficiency with our solutions. 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 Horizon Security 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 Horizon Security 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. Horizon Security 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 Horizon Security Analyzer 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 Horizon 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

Tags Share this article 2/20/23 Published A practical AWS security checklist will help you identify and address vulnerabilities quickly. In the process, ensure your cloud security posture is up-to-date with industry standards. This post will walk you through an 8-point AWS security checklist. We’ll also share the AWS security best practices and how to implement them. The AWS shared responsibility model AWS shared responsibility model is a paradigm that describes how security duties are split between AWS and its clients. This approach considers AWS a provider of cloud security architecture. And customers still protect their individual programs, data, and other assets. AWS’s Responsibility According to this model, AWS maintains the safety of the cloud structures. This encompasses the network, the hypervisor, the virtualization layer, and the physical protection of data centers. AWS also offers clients a range of safety precautions and services. They include surveillance tools, a load balancer, access restrictions, and encryption. Customer Responsibility As a customer, you are responsible for setting up AWS security measures to suit your needs. You also do this to safeguard your information, systems, programs, and operating systems. Customer responsibility entails installing reasonable access restrictions and maintaining user profiles and credentials. You can also watch for security issues in your work setting. Let’s compare the security responsibilities of AWS and its customers in a table: Comprehensive 8-point AWS security checklist 1. Identity and access management (IAM) 2. Logical access control 3. Storage and S3 4. Asset management 5. Configuration management. 6. Release and deployment management 7. Disaster recovery and backup 8. Monitoring and incidence management Identity and access management (IAM) IAM is a web service that helps you manage your company’s AWS access and security. It allows you to control who has access to your resources or what they can do with your AWS assets. Here are several IAM best practices: Replace access keys with IAM roles. Use IAM roles to provide AWS services and apps with the necessary permissions. Ensure that users only have permission to use the resources they need. Do this by implementing the concept of least privilege . Whenever communicating between a client and an ELB, use secure SSL versions. Use IAM policies to specify rights for user groups and centralized access management. Use IAM password policies to impose strict password restrictions on all users. Logical access control Logical access control involves controlling who accesses your AWS resources. This step also entails deciding the types of actions that users can perform on the resources. You can do this by allowing or denying access to specific people based on their position, job function, or other criteria. Logical access control best practices include the following: Separate sensitive information from less-sensitive information in systems and data using network partitioning Confirm user identity and restrict the usage of shared user accounts. You can use robust authentication techniques, such as MFA and biometrics. Protect remote connectivity and keep offsite access to vital systems and data to a minimum by using VPNs. Track network traffic and spot shady behavior using the intrusion detection and prevention systems (IDS/IPS). Access remote systems over unsecured networks using the secure socket shell (SSH). Storage and S3 Amazon S3 is a scalable object storage service where data may be stored and retrieved. The following are some storage and S3 best practices: Classify the data to determine access limits depending on the data’s sensitivity. Establish object lifecycle controls and versioning to control data retention and destruction. Use the Amazon Elastic Block Store (Amazon EBS) for this process. Monitor the storage and audit accessibility to your S3 buckets using Amazon S3 access logging. Handle encryption keys and encrypt confidential information in S3 using the AWS Key Management Service (KMS). Create insights on the current state and metadata of the items stored in your S3 buckets using Amazon S3 Inventory. Use Amazon RDS to create a relational database for storing critical asset information. Asset management Asset management involves tracking physical and virtual assets to protect and maintain them. The following are some asset management best practices: Determine all assets and their locations by conducting routine inventory evaluations. Delegate ownership and accountability to ensure each item is cared for and kept safe. Deploy conventional and digital safety safeguards to stop illegal access or property theft. Don’t use expired SSL/TLS certificates. Define standard settings to guarantee that all assets are safe and functional. Monitor asset consumption and performance to see possible problems and possibilities for improvement. Configuration management. Configuration management involves monitoring and maintaining server configurations, software versions, and system settings. Some configuration management best practices are: Use version control systems to handle and monitor modifications. These systems can also help you avoid misconfiguration of documents and code . Automate configuration updates and deployments to decrease user error and boost consistency. Implement security measures, such as firewalls and intrusion sensing infrastructure. These security measures will help you monitor and safeguard setups. Use configuration baselines to design and implement standard configurations throughout all platforms. Conduct frequent vulnerability inspections and penetration testing. This will enable you to discover and patch configuration-related security vulnerabilities. Release and deployment management Release and deployment management involves ensuring the secure release of software and systems. Here are some best practices for managing releases and deployments: Use version control solutions to oversee and track modifications to software code and other IT resources. Conduct extensive screening and quality assurance (QA) processes. Do this before publishing and releasing new software or updates. Use automation technologies to organize and distribute software upgrades and releases. Implement security measures like firewalls and intrusion detection systems. Disaster recovery and backup Backup and disaster recovery are essential elements of every organization’s AWS environment. AWS provides a range of services to assist clients in protecting their data. The best practices for backup and disaster recovery on AWS include: Establish recovery point objectives (RPO) and recovery time objectives (RTO). This guarantees backup and recovery operations can fulfill the company’s needs. Archive and back up data using AWS products like Amazon S3, flow logs, Amazon CloudFront and Amazon Glacier. Use AWS solutions like AWS Backup and AWS Disaster Recovery to streamline backup and recovery. Use a backup retention policy to ensure that backups are stored for the proper amount of time. Frequently test backup and recovery procedures to ensure they work as intended. Redundancy across many regions ensures crucial data is accessible during a regional outage. Watch for problems that can affect backup and disaster recovery procedures. Document disaster recovery and backup procedures. This ensures you can perform them successfully in the case of an absolute disaster. Use encryption for backups to safeguard sensitive data. Automate backup and recovery procedures so human mistakes are less likely to occur. Monitoring and incidence management Monitoring and incident management enable you to track your AWS environment and respond to any issues. Amazon web services monitoring and incident management best practices include: Monitoring API traffic and looking for any security risks with AWS CloudTrail. Use AWS CloudWatch to track logs, performance, and resource usage. Set up modifications to AWS resources and monitor for compliance problems using AWS Config. Combine and rank security warnings from various AWS user accounts and services using AWS Security groups. Using AWS Lambda and other AWS services to implement automated incident response procedures. Establish a plan for responding to incidents that specify roles and obligations and define a clear escalation path. Exercising incident response procedures frequently to make sure the strategy works. Checking for flaws in third-party applications and applying quick fixes. The use of proactive monitoring to find possible security problems before they become incidents. Train your staff on incident response best practices. This way, you ensure that they’ll respond effectively in case of an incident. Top challenges of AWS security DoS attacks A Distributed denial of service (DDoS) attack poses a huge security risk to AWS systems. It involves an attacker bombarding a network with traffic from several sources. In the process, straining its resources and rendering it inaccessible to authorized users. To minimize this sort of danger, your DevOps should have a thorough plan to mitigate this sort of danger. AWS offers tools and services, such as AWS Shield, to assist fight against DDoS assaults. Outsider AWS compromise. Hackers can use several strategies to get illegal access to your AWS account. For example, they may use psychological manipulation or exploit software flaws. Once outsiders gain access, they may use data outbound techniques to steal your data. They can also initiate attacks on other crucial systems. Insider threats Insiders with permission to access your AWS resources often pose a huge risk. They can damage the system by modifying or stealing data and intellectual property. Only grant access to authorized users and limit the access level for each user. Monitor the system and detect any suspicious activities in real-time. Root account access The root account has complete control over an AWS account and has the highest degree of access.Your security team should access the root account only when necessary. Follow AWS best practices when assigning root access to IAM users and parties. This way, you can ensure that only those who should have root access can access the server. Security best practices when using AWS Set strong authentication policies. A key element of AWS security is a strict authentication policy. Implement password rules, demanding solid passwords and frequent password changes to increase security. Multi-factor authentication (MFA) is a recommended security measure for access control. It involves a user providing two or more factors, such as an ID, password, and token code, to gain access. Using MFA can improve the security of your account. It can also limit access to resources like Amazon Machine Images (AMIs). Differentiate security of cloud vs. in cloud Do you recall the AWS cloud shared responsibility model? The customer handles configuring and managing access to cloud services. On the other hand, AWS provides a secure cloud infrastructure. It provides physical security controls like firewalls, intrusion detection systems, and encryption. To secure your data and applications, follow the AWS shared responsibility model. For example, you can use IAM roles and policies to set up virtual private cloud VPCs. Keep compliance up to date AWS provides several compliance certifications for HIPAA, PCI DSS, and SOC 2. The certifications are essential for ensuring your organization’s compliance with industry standards. While NIST doesn’t offer certifications, it provides a framework to ensure your security posture is current. AWS data centers comply with NIST security guidelines. This allows customers to adhere to their standards. You must ensure that your AWS setup complies with all legal obligations as an AWS client. You do this by keeping up with changes to your industry’s compliance regulations. You should consider monitoring, auditing, and remedying your environment for compliance. You can use services offered by AWS, such as AWS Config and AWS CloudTrail log, to perform these tasks. You can also use Horizon ACE to identify and remediate non-compliance events quickly. It enables customers to ensure their compliance with industry and government standards. The final word on AWS security You need a credible AWS security checklist to ensure your environment is secure.

Firewall Change Management How to secure your LAN (Local Area Network) Matthew Pascucci 2 min read Matthew Pascucci 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 11/12/13 Published How to Secure Your Local Area Network In my last blog series we reviewed ways to protect the perimeter of your network and then we took it one layer deeper and discussed securing the DMZ . Now I’d like to examine the ways you can secure the Local Area Network, aka LAN, also known as the soft underbelly of the beast. Okay, I made that last part up, but that’s what it should be called. The LAN has become the focus of attack over the past couple years, due to companies tightening up their perimeter and DMZ. It’s very rare you’ll you see an attacker come right at you these days, when they can trick an unwitting user into clicking a weaponized link about “Cat Videos” (Seriously, who doesn’t like cat videos?!). With this being said, let’s talk about a few ways we can protect our soft underbelly and secure our network. For the first part of this blog series, let’s examine how to secure the LAN at the network layer. LAN and the Network Layer From the network layer, there are constant things that can be adjusted and used to tighten the posture of your LAN. The network is the highway where the data traverses. We need protection on the interstate just as we need protection on our network. Protecting how users are connecting to the Internet and other systems is an important topic. We could create an entire series of blogs on just this topic, but let’s try to condense it a little here. Verify that you’re network is segmented – it better be if you read my last article on the DMZ – but we need to make sure nothing from the DMZ is relying on internal services. This is a rule. Take them out now and thank us later. If this is happening, you are just asking for some major compliance and security issues to crop up. Continuing with segmentation, make sure there’s a guest network that vendors can attach to if needed. I hate when I go to a client/vendor’s site and they ask me to plug into their network. What if I was evil? What if I had malware on my laptop that’s now ripping throughout your network because I was dumb enough to click a link to a “Cat Video”? If people aren’t part of your company, they shouldn’t be connecting to your internal LAN plain and simple. Make sure you have egress filtering on your firewall so you aren’t giving complete access for users to pillage the Internet from your corporate workstation. By default users should only have access to port 80/443, anything else should be an edge case (in most environments). If users need FTP access there should be a rule and you’ll have to allow them outbound after authorization, but they shouldn’t be allowed to rush the Internet on every port. This stops malware, botnets, etc. that are communicating on random ports. It doesn’t protect everything since you can tunnel anything out of these ports, but it’s a layer! Set up some type of switch security that’s going to disable a port if there are different or multiple MAC addresses coming from a single port. This stops hubs from being installed in your network and people using multiple workstations. Also, attempt to set up NAC to get a much better understating of what’s connecting to your network while giving you complete control of those ports and access to resources from the LAN. In our next LAN security-focused blog, we’ll move from the network up the stack to the application layer.
