Brava, a new Israeli cybersecurity startup, came out of stealth on Wednesday with a $15 million seed round. According to Geektime, the round was led by F2 and Pitango, with private investors including executives at Microsoft, Anthropic and Check Point.
The platform starts from the attack rather than the logs: AI agents trained on data from real attacks generate the telemetry an attack would leave in the organization's environment, without running any malware, and feed it through the detection systems to see whether an alert fires. When there is a gap, the system checks whether the detection rule is missing, broken, or whether the data never reaches the SIEM, and can write new rules.
According to CEO Idan Batsri, at a large Canadian healthcare provider the company found within ten minutes that 44% of the detection rules were broken. Brava was founded by Batsri and CTO Itay Gabbay, both alumni of Unit 8200 and the Talpiot program.
