Israeli Cybersecurity Startup Brava Security Raises $15 Million

Brava Security, an Israeli cybersecurity firm, has announced a seed funding round of $15 million, led by F2 Venture Capital and Pitango. The investment also includes participation from private investors, including executives from Anthropic, Microsoft, and Check Point.

Brava Security's platform is designed to train security systems and AI agents on how to identify cyberattacks within any organization. The technology aims to detect attacks that existing security systems might miss, correct identified vulnerabilities, and assist security teams in incident investigation. The company reports that its clients include Fortune 100 companies in retail, energy, and hospitality, as well as major Canadian healthcare firms Cushman & Wakefield and WELL Health.

The company highlights a growing problem where security systems can be fully functional yet still miss attacks due to incomplete telemetry data collection, issues with SIEM aggregation, or ineffective detection rules. This problem is exacerbated by the increasing use of AI agents for incident investigation, which may miss attacks that underlying defenses overlook. Brava's technology reverses this process by generating the specific telemetry an attack would produce in an organization's environment without actually executing the attack, thereby defining what defenses should detect.

The platform integrates with existing security systems, including Splunk, Google SecOps, and CrowdStrike, and over 70 other data sources. Initial findings are reportedly available within 10 to 15 minutes of implementation. Idan Bazri, co-founder and CEO of Brava, stated that organizations rushing to implement AI for cybersecurity risk making critical errors if the AI operates on unverified data. Itay Gabai, co-founder and CTO, added that their models generate necessary telemetry before an attack occurs to test defenses.

Yair Kessuto, General Partner at Pitango, commented that AI is dramatically changing the cyber threat landscape, necessitating a shift in defense strategies. He noted Brava's new approach with autonomous AI capabilities to handle a wide range of threats at unprecedented scales, providing security teams with greater certainty and control.

Brava Security was founded by Idan Bazri and Itay Gabai. The company employs approximately 20 people, including AI and cybersecurity researchers, with R&D in Israel and a growing marketing and sales team in the U.S. The funds will be used to accelerate platform development, expand market penetration, particularly in North America, and prepare for expansion into financial services and government sectors.
