Breach and Attack Simulation (BAS) and Adversarial Exposure Validation (AEV) within Filigran’s ecosystem turn threat intelligence into an active, operational defense capability. Powered by the OpenCTI knowledge graph, BAS/AEV continuously tests an organization’s resilience by emulating real adversary tactics, techniques, and attack paths. These controlled simulations validate security controls, uncover detection gaps, and measure how well teams can identify and respond to evolving threats. AI-driven enrichment and automation correlate simulation results with active threat campaigns, highlight true exposure points, and prioritize remediation. The result is a continuous, intelligence-driven validation loop that strengthens defenses before attackers can exploit weaknesses and keeps security posture aligned with the real-world threat landscape.
