success stories "AlgoSec’s Security Management Solution is incredibly powerful. Its intelligent process improvements have directly translated into the highest level of security and compliance for our customers’ networks" Background With over 45 years’ experience in the banking sector, Atruvia ( formerly Fiducia IT AG) is one of the top ten IT providers in Germany. Today, Atruvia manages the IT networks of nearly 1,100 banks, constituting more than 100,000 PC workstations, 6,600 servers and 25,000 self-service banking terminals. Responsible for ensuring the smooth and secure processing of more than 16 billion transactions per year for its customers, Atruvia’s risk mitigation and regulatory compliance strategies are of utmost importance. Challenge To protect its customer networks, Atruvia implemented a number of security solutions, including 60 Check Point and 20 Juniper firewall clusters. However, managing multiple firewalls in a multi-vendor environment proved challenging. “Performing vulnerability assessments for such a large and complex firewall environment was extremely time-consuming, labor-intensive and prone to human error,” says Lutz Bleyer, Atruvia’s Chief Information Security Officer. With multiple stakeholders at each of its client organizations, Atruvia required a structured change management process to prevent firewall policies from growing unmanageable and creating security risks. “We needed a proven firewall management and workflow solution to eliminate potential security risks while providing us with complete visibility into our customer networks, anytime, anywhere,” says Bleyer. Solution After an in-depth analysis, Atruvia chose the AlgoSec Security Management Solution to optimize its security, compliance and change management processes. “AlgoSec provided the most comprehensive, intelligent automation solution for our firewall operations, helping us increase efficiency while improving risk mitigation and compliance,” says Bleyer. Results AlgoSec’s topology-aware technology provides Atruvia with complete visibility into the security landscape of its customers’ networks. “AlgoSec’s in-depth visibility enables us to easily create a hierarchy profile and establish a competency baseline of operations for each networks’ firewalls, even when multiple vendor technologies are involved,” says Bleyer. Atruvia’s security consultants and auditors are now closely aligned with their customers’ IT teams, regardless of their location. “The level of visibility AlgoSec provides across our customers’ security networks, and the ability to perform coordinated tasks remotely with them, enables us to work hand-in-hand as a joint team,” says Bleyer. Atruvia also uses AlgoSec to automate policy change management across customers’ firewall environments, enabling the company to eliminate manual and inefficient processes associated with the security policy change lifecycle, save time and reduce the potential for human error. “AlgoSec has fundamentally changed how we manage sophisticated, multi-device, multi-vendor firewall environments. By automating our workflows, we’ve eliminated unnecessary policy changes and reduced the time required to process changes by half,” explains Bleyer. “Thanks to AlgoSec’s intelligent automation, we’ve gained valuable optimization capabilities enabling our teams to operate smarter and faster.” Another important AlgoSec feature is its automatic assessment and reporting capabilities, which help Atruvia ensure that it remains in continuous compliance with corporate governance rules and adheres to regulatory standards, including ISO 27001, ISO 27002 and Sarbanes-Oxley (SOX). Data and network security, particularly within the financial sector, requires incredible focus on risk management and mitigation. “With AlgoSec we can now analyze every change and its impact on the network before it is live, and focus on risk mitigation rather than crisis management.” In summary, Bleyer commented, “Not only does AlgoSec more than measure up from a technology perspective, but the integrity of the company and its employees has surpassed our expectations and raised the bar for what we look for in other partners.” Schedule time with one of our experts

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

success stories "AlgoSec now does the heavy lifting for us. It allows the engineers to focus more on providing greater levels of security than on process and change, so we’re able to provide a much more secure infrastructure for BT" Background A leading world-wide provider of communications services and solutions, BT serves customers in more than 170 countries. Its principal activities include the provision of networked IT services globally; local, national and international telecommunications services for use at home, at work and on the move; broadband, TV and internet products and services; and converged fixed/mobile products and services. Challenge BT’s internal network is a complex, highly segmented environment that has evolved over the last two decades throughout its worldwide locations. BT’s infrastructure relies on a large number of third-party domains and business-to-business connections with over 1,000 policy enforcement points, some of which date back a number of years.“The challenge facing BT is around the size of the estate, the complexity and our ability to demonstrate at audit that the rules within the policy are still appropriate, still valid, and still authorized,” says Phil Packman, General Manager of Security Gateway Operations for BT. “Equally, we’re challenged to ensure that rules don’t make it into the rulebase unless they’re approved and authorized.” BT therefore realized that it needed automation and reporting to better control its massive rulebase, and provide an approved audit trail to both auditors and internal stakeholders. Solution BT set about to solve its security challenges by creating a set of criteria for evaluating off-the-shelf, automated security solutions. “The criteria were based on ‘total costof ownership,’ our roadmap, and probably most importantly, the willingness of the partner to work with us,” says Packman. AlgoSec uniquely met BT’s requirements.Another feature BT liked was AlgoSec’s ability to prove that policies are implemented as approved. According to Packman, this was a capability “which we’d not seen in other products, and which we couldn’t achieve with our in-house tools.”AlgoSec’s commitment to customer success and its money-back guarantee were also deciding factors in BT’s selection process. Results Immediately after deployment, AlgoSec enabled BT to reduce error rates, make improvements to their rulebase implementation process and ultimately give BT better control over its network security. Packman explains: “Most notably, we were able to track down rogue connectivity, or connectivity that we didn’t understand properly. It gave us an almost immediate view of certain high-risk situations.”In addition, by using AlgoSec’s compliance reports, Packman’s engineering team were able to instantly demonstrate that no rules could be added to the firewall policy without proper approval — saving countless hours.Simplifying the audit preparation process led to a surprise benefit for BT’s Security Gateway Operations Team, which performs rule implementation and authorization: “AlgoSec has allowed us to change the skills profile of the team because the tool does the heavy lifting for us. Now our engineers can focus more on providing greater levels of security than on process and change, so we’re able to provide a much more secure infrastructure for BT.”Packman also endorses AlgoSec’s customer service, stating that the relationship has been a very positive one. “This has really helped put our minds at rest. We believe we’ve done the right thing in terms of deploying AlgoSec.”Using AlgoSec continues to enable BT to manage the complexity of its network with confidence, as it pursues growing and competitive global markets for its IT, computing, and communications services. Packman summarizes: “We have met every objective we hoped to achieve with AlgoSec.” Schedule time with one of our experts

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/24/22 Published 1. Application-centric security Many of today’s security discussions focus on compromised credentials, misconfigurations, and malicious or unintentional misuse of resources. Disruptive technologies from Cloud to smart devices and connected networks mean the attack surface is growing. Security conversations are increasingly expanding to include business-critical applications and their dependencies. Organizations are beginning to recognize that a failure to take an application-centric approach to security increases the potential for unidentified, unmitigated security gaps and vulnerabilities. 2. Portable, agile, API & automation driven enterprise architectures Successful business innovation requires the ability to efficiently deploy new applications and make changes without impacting downstream elements. This means fast deployments, optimized use of IT resources, and application segmentation with modular components that can seamlessly communicate. Container security is here to stay Containerization is a popular solution that reduces costs because containers are lightweight and contain no OS. Let's compare this to VMs, like containers, VMs allow the creation of isolated workspaces on a single machine. The OS is part of the VM and will communicate with the host through a hypervisor. With containers, the orchestration tool manages all the communication between the host OS and each container. Aside from the portability benefit of containers, they are also easily managed via APIs, which is ideal for modular, automation-driven enterprise architectures. The growth of containerized applications and automation will continue. Lift and Shift left approach will thrive Many organizations have started digital transformation journeys that include lift and shift migrations to the Cloud. A lift and shift migration enables organizations to move quickly, however, the full benefits of cloud are not realized. Optimized cloud architectures have cloud automation mechanisms deployed such as serverless (i.e – AWS Lamda), auto-scaling, and infrastructure as code (IaC) (i.e – AWS Cloud Formation) services. Enterprises with lift and shift deployments will increasingly prioritize a re-platform and/or modernization of their cloud architectures with a focus on automation. Terraform for IaC is the next step forward With hybrid cloud estates becoming increasingly common, Terraform-based IaC templates will increasingly become the framework of choice for managing and provisioning IT resources through machine-readable definition files. This is because Terraform, is cloud-agnostic, supporting all three major cloud service providers and can be used for on-premises infrastructure enabling a homogenous IaC solution across multi-cloud and on-premises. 3. Smart Connectivity & Predictive Technologies The growth of connected devices and AI/ML has led to a trend toward predictive technologies. Predictive technologies go beyond isolated data analysis to enable intelligent decisions. At the heart of this are smart, connected devices working across networks whose combined data 1. enables intelligent data analytics and 2. provides the means to build the robust labeled data sets required for accurate ML (Machine Learning) algorithms. 4. Accelerated adoption of agentless, multi-cloud security solutions Over 98% of organizations have elements of cloud across their networks. These organizations need robust cloud security but have yet to understand what that means. Most organizations are early in implementing cloud security guardrails and are challenged by the following: Misunderstanding the CSP (Cloud Service Provider) shared responsibility model Lack of visibility across multi-cloud networks Missed cloud misconfigurations Takeaways Cloud security posture management platforms are the current go-to solution for attaining broad compliance and configuration visibility. Cloud-Native Application Protection Platforms (CNAPP) are in their infancy. CNAPP applies an integrated approach with workload protection and other elements. CNAPP will emerge as the next iteration of must have cloud security platforms. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Tags Share this article 2/19/13 Published Podcast: Differences between UTM and NGFW In our recent webcast discussion alongside panelists from Fortinet, NSS Labs and General Motors, we examined the State of the Firewall in 2013. We received more audience questions during the webcast than the time allowed for, so we’d like to answer these questions through several blog posts in a Q&A format with the panelists. By far the most asked question leading up to and during the webcast was: “What’s the difference between a UTM and a Next-Generation Firewall?” Here’s how our panelists responded: Pankil Vyas, Manager – Network Security Center, GM UTM are usually bundled feature set, NGFW has bundle but licensing can be selective. Depending on the firewall’s function on the network, some UTM features might not be useful, creating performance issues and sometimes firewall conflicts with packet flows. Nimmy Reichenberg, VP of Strategy, AlgoSec Different people give different answers to this question, but if we refer to Gartner who are certainly a credible source, a UTM consolidates many security functions (email security, AV, IPS, URL filtering etc.) and is tailored mostly to SMBs in terms of management capabilities, throughput, support, etc. A NGFW is an enterprise-grade product that at the very least includes IPS capabilities and application awareness (layer 7 control). You can refer to a Gartner paper titled “Defining the Next-Generation Firewall” for more information. Ryan Liles, Director of Testing Services, NSS Labs There really aren’t any differences in a UTM and a NGFW. The technologies used in the two are essentially the same, and they generally have the same capabilities. UTM devices are typically classified with lower throughput ratings than their NGFW counterparts, but for all practical purposes the differences are in marketing. The term NGFW was coined by vendors working with Gartner to create a class of products capable of fitting into an enterprise network that contained all of the features of a UTM. The reason for the name shift is that there was a pervasive line of thought stating a device capable of all of the functions of a UTM/NGFW would never be fast enough to run in an enterprise network. As hardware has progressed, the capability of these devices to hit multi-gigabit speeds began to prove that they were indeed capable of enterprise deployment. Rather than try and fight the sentiment that a UTM could never fit into an enterprise, the NGFW was born. Patrick Bedwell, VP of Products, Fortinet There are several definitions in the market of both terms. Analyst firms IDC and Gartner provided the original definitions of the terms. IDC defined UTM as a security appliance that combines firewall, gateway antivirus, and intrusion detection / intrusion prevention (IDS/IPS). Gartner defined an NGFW as a single device with integrated IPS with deep packet scanning, standard first-generation FW capabilities (NAT, stateful protocol inspection, VPN, etc.) and the ability to identity and control applications running on the network. Since their initial definitions, the terms have been used interchangeably by customers as well as vendors. Depending on with whom you speak, UTM can include NGFW features like application ID and control, and NGFW can include UTM features like gateway antivirus. The terms are often used synonymously, as both represent a single device with consolidated functionality. At Fortinet, for example, we offer customers the ability to deploy a FortiGate device as a pure firewall, an NGFW (enabling features like Application Control or User- and Device-based policy enforcement) or a full UTM (enabling additional features like gateway AV, WAN optimization, and so forth). Customers can deploy as much or as little of the technology on the FortiGate device as they need to match their requirements. If you missed the webcast, you can view it on-demand.

Tags Share this article 1/27/20 Published The certification demonstrates AlgoSec’s commitment to protecting its customers’ and partners’ data Data protection is a top priority for AlgoSec, proven by the enhanced security management system we have put in place to protect our customers’ assets. This commitment has been recognized by the ISO, who has awarded AlgoSec the ISO/IEC 27001 certification . The ISO 27001 accreditation is a voluntary standard awarded to service providers who meet the criteria for data protection. It outlines the requirements for building, monitoring, and improving an information security management system (ISMS); a systematic approach to managing sensitive company information including people, processes and IT systems. The ISO 27001 standard is made up of ten detailed control categories detailing information security, security organization, personnel security, physical security, access control, continuity planning, and compliance. To achieve the ISO 27001 certification, organizations must demonstrate that they can protect and manage sensitive company and customer information and undergo an independent audit by an accredited agency. The benefits of working with an ISO 27001 supplier include: Risk management – Standards that govern who can access information. Information security – Standards that detail how data is handled and transmitted. Business continuity – In order to maintain compliance, an ISMS must be continuously tested and improved. Obtaining the ISO 27001 certification is a testament to our drive for excellence and offers reassurance to our customers that our security measures meet the criteria set out by a global defense standard.

AWS Security group architecture for AWS: How to overcome security group limits Prof. Avishai Wool 2 min read Prof. Avishai Wool 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 8/9/23 Published As with all cloud vendors, AWS users share responsibility for securing their infrastructure against risk. Amazon provides the tools you need to filter traffic, but configuring those tools is up to you. Firewalls are one of the tools you’ll use to filter traffic and secure Virtual Private Cloud (VPC) instances. Instead of using traditional firewalls, Amazon provides users with AWS security groups, which are flexible, stateful firewalls capable of filtering inbound and outbound traffic. However, there are limits to what you can do with AWS security groups. First, they only allow traffic – you can’t configure them to deny traffic. Second, the maximum number of rules you can set for a single group is 60. This isn’t a big issue for an Amazon EC2 instance designed to address inbound traffic. You’ll either want your AWS EC2 to accept ingress from the entire internet or you’ll want to configure access for a few internal IP addresses. But for outbound traffic, 60 rules simply isn’t enough. You’ll use a dozen of them just allowing access to GitHub’s API . Add in a few third-party partners and you’re already well past the limit. Amazon VPC resource limits explained Amazon sets clear limits on the AWS services and resources it makes available to users. In some cases, you can increase these limits by contacting AWS support. These limits are generally assessed on a per-Region basis. Here are some of the limits Amazon places on AWS users: Security group limits 2500 VPC security groups per Region 60 IPv4 rules per security group 60 IPv6 rules per security group 5 security groups per network interface VPC and subnet limits 5 VPCs per Region 200 Subnets per VPC 5 IPv4 CIDR blocks per VPC 5 IPv6 CIDR blocks per VPC Limits to elastic IP addresses and gateways 5 Elastic IP addresses per Region 2 Elastic IP Addresses per public NAT gateway 5 Egress-only internet gateways per Region 5 NAT gateways per Availability Zone One carrier gateway per VPC Prefix list limits 100 prefix lists per Region 1000 versions per prefix list 5000 prefix list references per resource type Network ACL limits 200 Network ACLs per VPC 20 Rules per Network ACL How to manage AWS cloud security group limits effectively Traditional firewalls may have thousands of security rules, including a complex combination of inbound rules and egress filters. Crucially, they can also enforce outbound rules that include denying traffic – something Amazon does not allow regular security groups to do. While AWS offers powerful tools for securing cloud workflows, Amazon VPC users must find ways to overcome these limitations. Fortunately, there are a few things you can do to achieve exactly that. Optimize your VPC security groups. Use Network Access Control Lists to secure assets at the subnet level. Use a domain name filtering system that reduces the number of IP addresses security group rules need to resolve. Optimize your Amazon virtual private cloud configuration Amazon VPC is a virtual network that contains many of the elements you’d expect from a traditional network. It has IP addresses, route tables, subnets, and internet gateways. Unlike a traditional network, you can easily configure many of your VPC environment through a command line interface (CLI). You can establish VPC peering connections, implement identity and access management (IAM) protocols, and configure elastic network interfaces without manually handling any hardware. But first, you need to set up and protect your VPC by setting up and configuring security groups. If you don’t specify a particular group, Amazon EC2 will use the default security group. If you haven’t added new security groups since creating your AWS account, you may only have that one default security group. The first step to optimizing security is expanding the number of security groups you have available. Here’s an example of the code you can use to create a new security group in the AWS console:aws ec2 create-security-group –group-name web-pci-sg –description “allow SSL traffic” –vpc-id vpc-555666777 This creates a new group named web-pci-sg and describes it as a group designed to allow SSL traffic on the network. Remember that security groups don’t support deny rules. Here is the code you would use to add a rule to that group: aws ec2 authorize-security-group-ingress \ –group-name web-pci-sg \ –protocol https \–port 443 \ –cidr This rule specifically allows SSL traffic using the HTTPS protocol to use port 443, which is the standard port for HTTPS traffic. You can use the last argument to specify the cidr block the rule will direct traffic through. This gives you the ability to manage traffic through specific subnets, which is important for the next step. This example focuses on just one type of rule in one context. To take full advantage of the security tools AWS makes available, you’ll want to create custom rules for endpoints, load balancers, nat gateways, and more. Although you’re limited to 60 rules per security group, creating many groups lets you assign hundreds of rules to any particular instance. Security architecture and network ACLs Network Access Control Lists provide AWS users with additional filtering capabilities. Network ACLs are similar to security groups in many ways, but come with a few key differences: Network ACLs can contain deny rules. You can write Network ACL rules to include explicit actions, like blocking particular IP addresses or routing VPN users in a specific way. Network ACLs are enforced at the subnet level. This means they apply to every instance in the subnet, in addition to whatever rules exist at the security group level. As mentioned above, each Network ACL can contain up to 20 rules. However, you can have up to 200 Network ACLs per VPC, which gives you a total of 4000 potential rules. Along with instance-specific security group rules, this offers much more flexibility for setting up robust AWS security architecture. Since Network ACLs can deny traffic, they are a useful tool for managing access to databases and other sensitive assets. For example, you may wish to exclude users who don’t have the appropriate permissions from your Amazon RDS instance. You may also want to filter SSH (Secure Shell) connections coming from unknown sources, or limit connections between different internal instance types. To do this effectively, you need to group these assets under the same subnet and make sure that the appropriate rules are enabled for all of them. You can also write asset-specific rules at the security group level, ensuring every asset has its own optimal configuration. The larger your AWS environment is, the more complex this process may become. Take care to avoid misconfigurations – it’s very easy to accidentally write security group rules and Network ACL rules that aren’t compatible, or that cause problems when you access the instance. To avoid this, try to condense your rules as much as possible. Avoid limits by filtering domain names directly Although you can create a large number of rules by creating additional security groups, you still may want to add more than 60 rules in a single group. There are many scenarios where this makes more sense than arbitrarily adding (and managing) new groups. For example, you might have a production instance that needs updates from several third-party partners. You also need to periodically change and update the technologies this instance relies on, so you’d like to keep its rules in a single security group. This reduces misconfiguration risk by keeping all the relevant rules in one place – not spread out across multiple groups. To overcome this limit, you need to reduce the number of IP addresses that the security group filters. You can do this by deploying a third-party solution that allows security rules to perform DNS resolution. This eliminates the need for AWS to resolve the domain name. Since AWS security groups can’t compute domain names on their own, you’ll need to deploy a third-party NAT gateway on your public VPC to filter outbound traffic in this way. Once you do this, you can write rules that filter outgoing connections based on their domain name. This effectively bypasses the 60 IP limit because you are not referring to specific IP addresses. At the same time, it simplifies management and makes rules much easier to read and understand. Instead of looking up and adding all of Github’s API IP addresses, you can write rules that reference the domain “Github.com”. If Github decides to change its IP infrastructure, your security rules will automatically reference the new addresses – you won’t have to go back and update them. The earlier you address AWS security group limits, the better There is an unlimited number of ways you can arrange your security groups and Network ACLs. Even in a small environment, the prospect may seem daunting. However, the flexibility Amazon provides to its cloud users is a valuable security feature. Those who go the process enjoy clear security performance benefits. If you start to planning for the architecture of your security and filtering policies early, you’ll be better equipped to scale those policies upwards as your organization grows. This will prevent security processes from becoming a growth bottleneck and maintain a high level of efficiency even as those policies become larger and more complex.
