Onit Security Raises $11M Seed to Automate Vulnerability Remediation
Vulnerabilities don’t usually fail loudly. They slip through quietly, logged, categorized, and parked in systems that were supposed to keep things under control. Everyone sees them. Everyone agrees they matter. And yet they sit, untouched, until timing turns them into something expensive. That friction between awareness and execution is exactly where Onit Security chose to build.
Ofer Amitai knows that story better than most. A known vulnerability, buried deep, ignored just long enough, turned into a real-world breach at Portnox. No Hollywood hacking montage. Just a gap, left open. So Ofer Amitai teamed up with Elad Ben Meir and Tom Winter and decided maybe the problem isn’t finding vulnerabilities. Maybe it’s actually doing something about them before someone else does.
Now Onit Security steps out of stealth with $11M in seed funding, co-led by Hetz Ventures and Brightmind Partners, and they’re not here to add another dashboard to your already crowded screen. They’re here to close the loop. Fully. Ingest, prioritize, assign, remediate. The stuff security teams talk about in theory but rarely execute at scale.
And here’s where it gets interesting. Some tools point at the problem. Others generate tickets and call it momentum. Onit Security leans into execution. Systems that understand business context, map ownership across messy environments, and carry remediation forward with human approval still in the loop. Translation: fewer tickets, fewer delays, and a serious dent in that 32-day industry average to fix what everyone already knows is broken.
Early numbers don’t whisper either. Up to 87% reduction in time-to-remediation. Around 15 Fortune 1000 customers already in the mix at launch. Not experimenting. Operating. That’s what happens when founders have already seen exits with SCADAfence, Portnox, and For-Each. Pattern recognition starts to look like instinct.
Hetz Ventures and Brightmind Partners didn’t just write checks here. They backed a shift. Because the vulnerability market isn’t shrinking. It’s expanding toward a projected 1M CVEs by 2030, and most companies are still stuck playing defense with tools built for visibility, not resolution.
Onit Security is leaning into that gap with a decision-based architecture that compounds over time. Solve it once, teach the system, and let it handle the rest. Less noise. More action. It’s the difference between knowing your house has a leak and actually fixing the pipe before the floor caves in.
