Brava Security Emerges From Stealth With $15 Million

Tel Aviv-based security operations startup Brava Security has emerged from stealth with $15 million in seed funding led by F2 Venture Capital and Pitango VC. Several angel investors also participated in the round.

Founded in 2024 by Israeli intelligence veterans Idan Basre and Itay Gabbay, Brava is developing an artificial intelligence platform that models attacker behavior and simulates cyberattacks in a customer’s environment. Basre is the chief executive, and Gabbay is the chief technology officer.

The platform analyzes the telemetry generated by simulated attacks across a company’s security systems. It uses information about the company’s business and technology environment to show how an attack might appear in its logs, identify defenses that could fail to detect it and rewrite security information and event management, or SIEM, detections. Security teams can then examine the results.

“The hard part of security was never writing detections. It’s knowing exactly what an attack will look like in a specific environment, across all of its log sources, before it ever happens. That’s the problem our models were built to solve,” Gabbay said.

Brava said its platform addresses a limitation of artificial intelligence agents used for security investigations: They generally cannot investigate attacks that existing defenses have not detected.

“You can’t automate a decision based on evidence no one ever proved. We’re solving the problem that comes before AI can make the right decision: making sure the security infrastructure actually sees the threats it’s supposed to detect,” Basre said.

The company said its platform can produce initial findings within 10 to 15 minutes of onboarding. It connects with more than 70 data sources and destinations and does not require changes to a customer’s existing security infrastructure.

Brava plans to use the funding for product development and market expansion. The company has an R&D team in Israel and a commercial team in the United States.
