Brava Security Raises $15 Million to Validate AI Cyber Defenses

Brava Security, an Israeli-founded cybersecurity startup, has secured $15 million in funding to advance its platform designed to validate the effectiveness of enterprise security systems. The company addresses a critical gap in modern cybersecurity: while many organizations deploy AI-assisted defense tools, these systems are only as effective as the underlying detection rules within their Security Information and Event Management (SIEM) platforms. Brava’s solution utilizes multi-agent technology to model complex attacker behaviors, simulating how specific techniques would appear across a customer’s log sources. By testing whether these traces would trigger actual alerts, the platform provides evidence-based validation of an enterprise's security posture. Founded by CEO Basre and CTO Itay Gabbay—both veterans of the IDF’s Unit 8200—the company combines deep AI research with practical security engineering. The platform is designed to deliver initial insights within minutes, helping CISOs and security teams identify gaps in their detection coverage before an actual breach occurs. With R&D operations based in Israel and a growing commercial presence in the U.S., Brava is positioning itself as a critical layer in the autonomous security stack, ensuring that AI-driven security decisions are supported by verified, reliable data rather than assumptions.
