success stories "We cut the time it takes to implement firewall rules by at least 50%" Application owners for global retail chain get faster response times with application visibility and automated deployment. Orange Cyberdefense is the expert cybersecurity business unit of the Orange Group, providing managed security, managed threat detection & response services to organizations around the globe. They embed security into Orange Business Services solutions with more than 250 security researchers and analysts and 16 SOCs distributed around the world supporting customers in over 160 countries. The Challenge Orange Cyberdefense is an on-site consultant for a large retail chain with hundreds of stores and hundreds of thousands of employees spread out across the world.The client has over 2,500 multi-vendor firewalls and Layer 3 devices in their global data centers. They also run hundreds of mission-critical business services. Business services include supply chain management and ERP systems, global eCommerce operations, financial management systems, and much more. As a result, they had to cope with hundreds of change requests daily.Some of the challenges included: Lack of centralized management – Multiple vendors’ firewalls are deployed, which were implemented by multiple third-party vendors. There was no validation that rules were consistently applied across multiple vendor’s management consoles. Commissioning and decommissioning devices – A mix of multi-vendor new and legacy devices run in the data center and maintaining consistency across multiple vendors and multiple versions of devices was difficult. Lack of automation – Firewall communication and traffic flows were described in Excel sheets and needed to be manually updated whenever there was a change. Slow execution of change requests – Implementing firewall changes took over a week. Poorly implemented rules – The rules did not reflect what the requester asked for. They either allowed too much traffic in or were too narrow, not allowing the required traffic and thus needed to be re-implemented. The Solution The client searched for a solution that provided: Faster implementation of firewall changes. Comprehensive firewall support for a globally dispersed multi-vendor, hybrid estate. Automation of security policy change management and documentation of security policy changes. Visibility into their business applications and traffic flows. They implemented the AlgoSec Security Policy Management Solution, made up of AlgoSec Horizon Security Analyzer, AlgoSec Horizon FireFlow, and AlgoSec Horizon AppViz and AppChange (formerly AlgoSec BusinessFlow). AlgoSec Horizon Security Analyzer analyzes complex network security policies across on-premise, cloud, and hybrid networks. It automates and simplifies security operations, including troubleshooting, auditing and risk analysis. Using Horizon Security Analyzer, the client can optimize the configuration of firewalls, and network infrastructure to ensure security and compliance. AlgoSec Horizon FireFlow enables security staff to automate the entire security policy change process from design and submission to proactive risk analysis, implementation, validation, and auditing. Its intelligent, automated workflows save time and improve security by eliminating manual errors and reducing risk. AlgoSec Horizon AppViz and AppChange (formerly AlgoSec BusinessFlow) discover, identify, and map business applications, providing critical security information regarding the firewalls and firewall rules supporting each connectivity flow. With AlgoSec AppChange, changes can be made at the business application level, including application migrations, server deployment, and decommissioning projects. The Results Some of the ways the client benefits from using AlgoSec include: Greater transparency by providing a single source of truth that took into consideration the entire network estate. 50% reduction in the time needed to implement firewall rules. More communication between network security/IT staff and business application owners who are now able to submit change requests in business language and easily describe their needs, thus reducing misconfigurations and potential breaches. Better compliance reporting – with both an easy API integration and also audit-ready compliance reports. Automated change management – network changes are now recorded while being made – not managed with Excel. By using AlgoSec, application owners have more visibility into the network and are better able to trace what has changed within their business applications. “Documentation is several hundred percent better this way,” said Hans Broomé, Network and Security Consultant at Orange Cyberdefense. “With many different versions of the services, by using AlgoSec the IT team is confident that they are making changes to the correct version.” There were even unexpected gains, such as improved security management procedures. Change requests became more accurate as they gained visibility into the network and made the change request process more systematic and transparent. Requesters, as well as stakeholders such as their managers, have full visibility of their change request’s status and can verify that the request works as intended. Orange Cyberdefense is also impressed with the dedicated attention they receive from AlgoSec. AlgoSec’s support team is familiar with the global organization and provides dedicated attention tailored to their exact needs. They stay up to date with the AlgoSec solution’s latest capabilities, and the technical team maximizes their use of it thanks to an extensive training library. “The best is yet to come,” concluded Broomé.

Zero trust vs micro segmentation Select a size Which network Can AlgoSec be used for continuous compliance monitoring? Yes, AlgoSec supports continuous compliance monitoring. As organizations adapt their security policies to meet emerging threats and address new vulnerabilities, they must constantly verify these changes against the compliance frameworks they subscribe to. AlgoSec can generate risk assessment reports and conduct internal audits on-demand, allowing compliance officers to monitor compliance performance in real-time. Security professionals can also use AlgoSec to preview and simulate proposed changes to the organization’s security policies. This gives compliance officers a valuable degree of lead-time before planned changes impact regulatory guidelines and allows for continuous real-time monitoring. Microsegmentation Zero Trust: How Microsegmentation Drives Zero Trust Success Microsegmentation zero trust is the practice of enforcing zero trust principles through fine‑grained, application‑aware segmentation at the workload and service level. Companies today are turning to microsegmentation, a granular form of network segmentation, to contain attacks quickly, prove least‑privilege access, and simplify compliance across hybrid environments. Despite still having to spend an average of $4.4 million per breach, according to IBM's Cost of a Data Breach Report 2025 , this is 9% lower than 2024. That drop ties directly to faster identification and containment—outcomes microsegmentation accelerates by limiting lateral movement and shrinking the blast radius from the first indicator of compromise. In yet another study, Verizon’s 2025 Data Breach Investigations Report , more than 12,000 confirmed breaches demonstrated how multi-stage intrusions use lateral movement, which microsegmentation technology directly addresses. Meanwhile, the Payment Card Industry Data Security Standard (PCI DSS) requires network segmentation for system scope reduction, which leads to decreased audit work and better system isolation. Taken together, these findings underscore a simple point: Organizations need application‑aware controls—specifically microsegmentation—to stop attackers from moving between systems and to operationalize zero trust. This article discusses the zero trust vs. micro‑segmentation debate, explains how zero trust and microsegmentation in fact work together, and provides a path to design, enforce, and operate this approach. What Is Microsegmentation? Microsegmentation divides networks into small, secure domains that match workload requirements and user/service identities with explicit allow‑rules to stop lateral movement. Network security today benefits from application-based boundaries, i.e., policies applied where applications actually communicate—not just subnets and VLANS. In practice, that means protecting individual workloads and the communication between them across data centers, public clouds, containers, and endpoints—rather than vaguely “protecting components” or “locations.” What Is the Difference Between Traditional (Macro) and Micro-Segmentation This comparison comes down to a difference in approach: Macro-segmentation uses broad VLANs and subnets or DMZs to divide network tiers; while this provides limited east-west control, it is simpler to design. Micro-segmentation uses SDN and host agents, as well as cloud security groups; application-specific policies are enforced at the workload/service boundary, which is why they are the engine of microsegmentation zero trust. What Role Do Firewalls and Network Segmentation Layers Play in Microsegmentation? Your existing perimeter and internal firewalls provide north‑south control, compliance zones, and enforcement points that microsegmentation can orchestrate. In other words, microsegmentation complements firewalls and network segmentation layers—it does not replace them. Extending the point above: Microsegmentation orchestrates those firewall and segmentation layers to deploy least‑privilege across hybrid systems—specifically: Cloud security groups NACLs SDN fabrics Kubernetes policies Host-based controls Since these layers are complementary, they collectively shrink the blast radius. What Is Zero Trust? Zero trust is a security concept, not a product or service. The system uses identity-based dynamic authorization, which takes into account device health status and environmental context—instead of traditional static location-based access methods. Verification is continuous because environments and risk conditions evolve. Zero trust verifies every access decision—no implicit trust—and enforces least privilege Zero Trust vs. Micro‑Segmentation: Complementary Forces While zero trust operates as an operational framework, microsegmentation functions as an implementation methodology. While zero trust explains what needs protection and which aspects require protection, microsegmentation provides the how. The table below breaks down the two concepts across key parameters. Aspect Zero Trust (Strategy) Microsegmentation (Mechanism) Focus Identity, posture, continuous verification Allowed app/workload flows Scope Enterprise‑wide architecture App tiers, services, identities Enforcement Policies derived from context and risk SDN, host agents, security groups, firewalls Outcome Minimized implicit trust; provable least‑privilege Contained blast radius; fewer lateral‑movement paths What Is Microsegmentation Zero Trust? The combination of zero trust and microsegmentation forms microsegmentation zero trust—a strategy connected to enforcement. The three primary goals of this approach are: Risk reduction Lateral movement prevention Least privilege verification Microsegmentation zero trust applies zero trust principles—continuous verification and least privilege—by defining and enforcing explicit, application‑aware allow‑rules between identities, services, and workloads. Why Does Microsegmentation Zero Trust Matter? It matters because it measurably reduces lateral movement paths and speeds incident containment. Authorized paths are explicitly permitted communication flows (service A to service B on port X from an approved identity) that have been validated as necessary for the application to function. Pre‑defining and testing these authorized paths speeds deployment because changes ship with pre-validated, least‑privilege policies—reducing last‑minute firewall rework, minimizing approvals, and preventing rollback from unexpected blocks. Implementing Microsegmentation to Achieve Zero Trust Microsegmentation is a continuous process, consisting of multiple stages to successfully achieve zero trust. Asset & Dependency Discovery Start by analyzing the network traffic behavior of applications and workloads in traditional on-premises setups, public clouds, and container environments. This application-first view serves as the base for zero trust segmentation, which stops security gaps from occurring. Policy Creation Create allow‑lists for individual app components and identity groups based on observed application traffic flows (sources/destinations, ports, processes) and documented business requirements, then validate with “what‑if” simulations before production. Enforcement Implement the approved policy through current controls—cloud security groups, firewalls, SDN fabrics, host controls, and Kubernetes—to achieve uniform protection across hybrid and multi-cloud systems. Continuous Monitoring & Adaptive Policy Continuously monitor for drift, prune unused rules, and adjust policies using detection data—without re‑introducing broad implicit trust or “allow any” access. Challenges & Pitfalls to Avoid Security organizations that operate effectively still encounter various obstacles when implementing microsegmentation: Lack of visibility in application maps: When third-party or SaaS endpoints and ephemeral services (containers, serverless functions) are not properly documented, visibility suffers. The fix? Run continuous dependency discovery operations while keeping tags and labels up to date. Focusing solely on network-based controls: Ignoring workload and identity context can weaken your security measures. The fix? Use service accounts, workload identities, namespaces, and labels as the basis for policy connections whenever possible. Relying on a single technology: Depending only on firewalls or security groups can create gaps in your security posture. The fix? Implement security orchestration using a combination of firewalls, SDN security groups, and Kubernetes network policies. Manual exception handling: Human intervention creates delays, slowing down release cycles. The fix? Orchestrate a combination of controls—next‑gen firewalls, SDN fabrics, cloud security groups, and Kubernetes network policy—so each layer covers the others.

Survey finds that 58% of respondents are concerned about security in the cloud, while misconfigurations are one of the leading causes of breaches and outages as public cloud adoption doubles over past two years Cloud Security Alliance Releases Latest Survey Report on State of Cloud Security Concerns, Challenges, and Incidents Survey finds that 58% of respondents are concerned about security in the cloud, while misconfigurations are one of the leading causes of breaches and outages as public cloud adoption doubles over past two years March 30, 2021 Speak to one of our experts SEATTLE – March 30, 2021 – The Cloud Security Alliance (CSA), the world’s leading organization dedicated to defining and raising awareness of best practices to help ensure a secure cloud computing environment, and AlgoSec , a leading provider of business-driven network and cloud security management solutions, today announced the results of a new study titled, “ State of Cloud Security Concerns, Challenges, and Incidents .” The survey, which queried nearly 1,900 IT and security professionals from a variety of organization sizes and locations, sought to gain deeper insight into the complex cloud environment that continues to emerge and that has only grown more complex since the onset of the pandemic. The survey found that over half of organizations are running 41 percent or more of their workloads in public clouds, compared to just one-quarter in 2019. In 2021, 63 percent of respondents expect to be running 41 percent or more of their workloads in public cloud, indicating that adoption of public cloud will only continue. Sixty-two percent of respondents use more than one cloud provider, and the diversity of production workloads (e.g. container platforms, virtual machines) is also expected to increase. Key findings include: Security tops concerns with cloud projects : Respondents’ leading concerns over cloud adoption were network security (58%), a lack of cloud expertise (47%), migrating workloads to the cloud (44%), and insufficient staff to manage cloud environments (32%). It’s notable that a total of 79 percent of respondents reported staff-related issues, highlighting that organizations are struggling with handling cloud deployments and a largely remote workforce. Cloud issues and misconfigurations are leading causes of breaches and outages : Eleven percent of respondents reported a cloud security incident in the past year with the three most common causes being cloud provider issues (26%), security misconfigurations (22%), and attacks such as denial of service exploits (20%). When asked about the impact of their most disruptive cloud outages, 24 percent said it took up to 3 hours to restore operations, and for 26 percent it took more than half a day. Nearly one-third still manage cloud security manually : Fifty-two percent of respondents stated they use cloud-native tools to manage security as part of their application orchestration process, and 50 percent reported using orchestration and configuration management tools such as Ansible, Chef and Puppet. Twenty-nine percent said they use manual processes to manage cloud security. Who controls cloud security is not clear-cut : Thirty-five percent of respondents said their security operations team managed cloud security, followed by the cloud team (18%), and IT operations (16%). Other teams such as network operations, DevOps and application owners all fell below 10 percent, showing confusion over exactly who owns public cloud security. “The use of cloud services has continued to increase over the past decade. Particularly now, in the wake of the COVID-19 public health crisis. With organizations struggling to address a largely remote workforce, many enterprises’ digital transformations have been accelerated to enable employees to work from home,” said Hillary Baron, lead author and research analyst, Cloud Security Alliance. “As an ever-more complex cloud environment continues to evolve, the need for supplementary security tools to improve public cloud security will, as well.” “In the face of complex environments, a dearth of security staff, and an overall lack of cloud knowledge, organizations are turning to security tools that can help supplement their workforce. Three of the top four benefits organizations look for in security management tools involve proactive detection of risks and automation. These types of tools can supplement the challenges many organizations are experiencing with lack of expertise (47%) and staff (32%), as well as improve visibility as they move toward an ever-changing cloud environment,” said Jade Kahn, AlgoSec Chief Marketing Officer.AlgoSec commissioned the survey to add to the industry’s knowledge about hybrid-cloud and multi-cloud security.
