Cyber startup Onit raises $11 million Seed round to tackle vulnerability management
Founded after an Iranian cyberattack, the company aims to cut response times from months to minutes.
Cybersecurity startup Onit Security, which develops a vulnerability management platform, has raised $11 million in a Seed round led by Hetz Ventures and Brightmind Partners, with participation from additional prominent angel investors.
The company was founded in 2025 by Elad Ben-Meir, Ofer Amitai, and Tom Winter, experienced entrepreneurs with three prior acquisitions - SCADAfence (acquired by Honeywell), Portnox (sold to private equity), and For-Each (acquired by Autodesk).
The idea for Onit Security emerged following an Iranian cyberattack on a company previously managed by Amitai. In that incident, attackers exploited a known vulnerability that had been deprioritized in favor of addressing thousands of more critical weaknesses. The episode highlighted a structural flaw in how organizations manage vulnerabilities, leaving them exposed despite significant security efforts.
Onit Security’s platform aims to dramatically reduce the time between vulnerability detection and remediation, from months to minutes. Its AI-driven agents prioritize vulnerabilities based on the specific business and technical context of each organization, rather than relying solely on generic severity rankings.
"Vulnerability management has been broken for 30 years. Security teams are weighed down by countless alerts, while attackers exploit the smallest window of inaction,” said Elad Ben Meir, CEO and Co-founder of Onit Security. "Combining a deep understanding of business context alongside the agility to rapidly respond to and remediate emerging threats, Onit brings a potent mix of intelligence with speed, currently unmatched. We are automating remediation at pace, at scale and future-proofing enterprises as they grow and as the cyber landscape around them evolves.”
