Onit Security Raises $11 Million to Automate Exposure Remediation at Scale

New updates have been reported about Onit Security.

Onit Security has emerged from stealth with an $11 million seed round to accelerate its agentic exposure management platform, positioning the company to address mounting vulnerability backlogs that now exceed 100,000 issues in many enterprises. The round was led by Hetz Ventures and Brightmind Partners, with participation from notable angel investors, and follows an Iranian state-sponsored cyberattack on co-founder Ofer Amitai’s prior company that exploited a known vulnerability buried in an overloaded remediation queue.

The Tel Aviv-based startup focuses on compressing the gap between identifying exposures and fixing them, a window that currently averages 32 days for remediation while attackers can exploit weaknesses in minutes. Onit’s AI-driven agents move beyond ticket generation by automatically mapping asset ownership, applying business context to prioritize issues, and executing remediation workflows, allowing a single resolution strategy to be reused across similar vulnerabilities and reducing mean time to remediation by up to 87% for current Fortune 1000 customers.

CEO and co-founder Elad Ben Meir said traditional vulnerability management has been ineffective for decades because security teams are overwhelmed by alerts while adversaries capitalize on short periods of inaction, and he positioned Onit as a way to future-proof enterprises as cyber risk and operational complexity grow. The company’s approach directly targets the industry bottleneck where risk-based vulnerability management and legacy scanners stop at detection, which Brightmind Partners’ general partner Gur Talpaz described as the critical gap between knowing what is wrong and actually fixing it.

Onit’s platform ingests data from disparate security and IT sources, uses embedded institutional knowledge to determine who owns which assets, and orchestrates end-to-end remediation without the manual hand-offs that currently slow response and inflate backlog risk. With Common Vulnerabilities and Exposures projected to surpass one million by 2030, the company is positioning its agentic architecture as a way for defenders to respond at attacker speed and gradually shrink unmanaged exposure inventories rather than watch them expand.

Founded in 2025 by serial cybersecurity entrepreneurs behind exits to Honeywell, private equity, and Autodesk, Onit plans to deploy the new capital into product development and go-to-market expansion across additional sectors beyond its existing large-enterprise base. For executives, the key implications are potential reductions in operational security overhead, faster risk reduction, and a path toward more autonomous, self-healing security postures as exposure management shifts from manual coordination to automated execution.
