Onit Security, an agentic exposure management company, has raised $11m in seed funding as it looks to overhaul how organisations detect and respond to cybersecurity vulnerabilities.
The round was led by Hetz Ventures and Brightmind Partners, with additional participation from a number of prominent angel investors.
The company’s platform is designed to close the gap between identifying a security exposure and actually resolving it — a problem that has plagued enterprise security teams for decades.
Unlike most existing tools, which stop at generating tickets, Onit’s AI agents prioritise vulnerabilities based on real business context rather than generic severity scores. The platform also automatically determines asset ownership by drawing on institutional knowledge spread across fragmented data sources, and executes remediation without relying on manual hand-offs between teams.
Critically, once a resolution strategy is defined, Onit applies it automatically to all similar future exposures, meaning remediation compounds over time and operates at machine speed.
The $11m raise will be used to accelerate product development and expand the company’s go-to-market efforts as it moves into additional sectors.
The funding comes against a stark backdrop for the cybersecurity industry. Security teams currently take an average of 32 days to remediate vulnerabilities, while nearly half remain unresolved after 12 months.
The number of Common Vulnerabilities and Exposures is projected to surpass one million by 2030 — a 300% increase from 2025 — meaning the backlog facing security teams is only set to worsen. Onit Security itself was founded following an Iranian state-sponsored cyberattack on co-founder Ofer Amitai’s previous company, in which attackers exploited a known vulnerability that had been buried in an unmanageable prioritisation queue. The company is currently working with Fortune 1000 clients and claims to have reduced mean time to remediation by up to 87%.
The founding team brings considerable pedigree, having previously built and exited three companies: SCADAfence, acquired by Honeywell; Portnox, sold to private equity; and For-Each, acquired by Autodesk.
Onit Security CEO and co-founder Elad Ben Meir said, “Vulnerability management has been broken for 30 years. Security teams are weighed down by countless alerts, while attackers exploit the smallest window of inaction. 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.”
