Brava Security, a startup that builds AI agents to test whether a company's security detections actually work, said Wednesday it has emerged from stealth with a $15 million seed round co-led by F2 Venture Capital and Pitango, according to the company's announcement dated Nov. 4, 2026.
The company says its customers have cut spending on security information and event management software, known as SIEM, by 65 percent to 85 percent. The announcement offers no named before-and-after study, sample size, measurement period or cost breakdown behind that figure, so it is best read as a marketing claim rather than a verified result.
A bet on checking the data first
F2's investment rationale, also published Nov. 4, said its interest was driven by a specific worry: autonomous agents in security operations centers, or SOCs, depend on telemetry (the logs and signals that security tools collect), and nobody is confirming that the telemetry is any good. F2 framed Brava as distinct from products that merely speed up the investigation of alerts that already exist.
According to F2, Brava reports initial findings 10 to 15 minutes after a customer is onboarded. F2 also listed integrations with Splunk, Google SecOps, CrowdStrike and more than 70 other sources and destinations. F2 relayed these as company claims, and they have not been independently benchmarked.
Investors and headcount
Maor Fridman of F2 and Yair Cassuto of Pitango are the investors associated with the round, according to an indexed F2 LinkedIn announcement. CTech identified Cassuto as a general partner at Pitango and did not disclose a board appointment.
CTech reported that Brava has roughly 20 employees, with research and development based in Israel and a growing commercial team in the United States. Tech Funding News independently reported about 20 employees the same day.
Third-party databases are less consistent. Signalbase lists two employees, though Brava's LinkedIn page gives a company-size band of 11 to 50. Mandos lists two seed rounds with undisclosed amounts, but other sources identified only the $15 million financing.
F2's portfolio page records "First Partnered: 2024" for Brava. That points to an earlier relationship between the firm and the company, but not to a separately quantified financing in 2024.
Customers and founders
F2 named Cushman & Wakefield and WELL Health as customers, along with unnamed Fortune 100 companies in retail, energy and hospitality. F2 did not say that every named customer belongs to the Fortune 100.
Brava's own biography of its chief executive, Idan Basre, describes 17 years in cybersecurity, a background in Talpiot (the Israeli military's elite technology program), a decade researching attacker behavior in Unit 8200, and later product leadership at Microsoft Defender. These are company-supplied claims. F2 said a co-founder spent seven years building core AI systems in the Israel Defense Forces, including work on a joint program involving DARPA and Israel.
Dealroom said the round falls within the top 4 percent of Israeli seed rounds, based on a database of 3,899 rounds.
A crowded field
Brava is entering a market that has seen other notable activity. SecurityWeek reported on March 3, 2026, that Fig Security launched with $38 million. Cribl announced an acquisition of CardinalOps on July 14, 2026, and Pentera said on Jan. 6, 2026, that it had passed $100 million in annual recurring revenue. The available reporting offers no detail on how those companies compare with Brava.
What comes next
Dealroom, citing an Axios interview with Basre, said Brava might seek a Series A within 12 months. That is a possibility, not an announced round.
