Organizations that rely on this "castle and moat" model put a lot of effort into perimeter defenses but they often leave the inside vulnerable, failing to stop lateral movement, often causing catastrophic damage.
While VPNs are often seen as the backbone of a castle and moat strategy, they increasingly fall short in today's complex environments. Organizations cite growing concerns over lateral movement, rising operational complexity, and the need to evolve toward zero trust strategies to address these gaps.
The limitations of traditional VPNs highlight the urgent need for a modern approach to security. One that eliminates implicit trust, simplifies operations, and scales effortlessly with organizational growth. Central to this modern approach is user-to-app segmentation, which ensures that users are granted precise access only to the applications they need. By implementing user-to-app segmentation, organizations can reduce the attack surface, streamline operational efficiency, and enable scalable zero trust access control, forming a critical foundation for stronger security in dynamic environments.
Achieving Zero Trust at the Speed of AI
AI-powered App Segmentation eliminates the slow, manual work of defining, implementing, and maintaining access policies that prevents you from achieving true Zero Trust Network Access (ZTNA). Instead of struggling to discover applications, create complex granular policies, and keep them updated as your environment scales, AI-powered App Segmentation uses machine learning to automate the entire process. The result is a fully implemented Zero Trust architecture, delivered with the speed and precision that only AI can provide.
AI-powered Segmentation delivers on this promise through four core capabilities:
Eliminate Lateral Threat Movement with Precise Segmentation by leveraging AI/ML-powered App Segmentation Insights, which dynamically clusters applications based on traffic patterns and shared behaviors through heuristic analysis and co-occurrence modeling. These precise groupings are then processed by the AI-Powered Recommendations, which applies advanced ML techniques to evaluate user roles, behaviors, and application clusters. The result is highly accurate, least-privilege access policies that eliminate unnecessary pathways and prevent lateral movement.
- Accelerate Policy Deployment with Intelligent Automation by leveraging Adaptive App Ranking, which uses AI/ML to analyze application group risks through domain similarity, IP relationships, transaction metrics, and usage patterns. This dynamic prioritization ensures security teams can focus on the most critical application groups first, eliminating manual guesswork and accelerating Zero Trust policy deployment.
- Faster Onboarding of Private Applications by leveraging Bulk App Import that streamlines onboarding by enabling seamless bulk integration of private application details from trusted third-party tools like Qualys, Tenable, and ServiceNow. These automated processes reduce errors, minimize manual effort, and allow teams to rapidly create granular, precise access policies.
- Gain Complete Visibility Into Existing App Segments, User Groups, and Policy Usage by using App Discovery to identify unmanaged applications in your environment. This AI/ML-powered capability monitors wildcard app segments and analyzes traffic data, including FQDNs, ports, and protocols to dynamically surface unmanaged applications, providing continuous visibility.
