TrueFort

TrueFort was a cybersecurity company that provided real-time microsegmentation tools and solutions aimed at securing modern enterprise environments. The company's platform focused on microsegmentation — a network security technique that divides a network into smaller, isolated segments to limit lateral movement by attackers and reduce the attack surface within an organization's infrastructure. TrueFort's solutions were designed to give security teams visibility into workload behavior and communication patterns, enabling them to define and enforce granular access policies at the application and workload level. This approach aligned with Zero Trust principles, where trust is never assumed and access is continuously verified based on context. The company targeted enterprise customers seeking to protect east-west traffic within their networks — communications between internal systems and applications — which traditional perimeter-based security tools often leave insufficiently monitored. As of May 21, 2025, TrueFort ceased all operations and is no longer conducting business. The company indicated it would provide best-effort support to existing customers in the short term following the shutdown.
