Onit Security, a cybersecurity startup that builds tools to find and fix security weaknesses, has raised $11 million in a Seed funding round. The round was led by Hetz Ventures and Brightmind Partners.
Other well-known angel investors also took part in the funding round, supporting the company’s growth and future plans.
The idea for Onit Security came after an Iranian cyberattack on a company that Amitai had managed. In that attack, hackers used a known security weakness that had been ignored while the team focused on fixing more serious issues.
This showed a bigger problem in how companies handle security risks. Even after putting in a lot of effort, they can still be exposed if some vulnerabilities are overlooked.
“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.”
The company was started in 2025 by Elad Ben-Meir, Ofer Amitai, and Tom Winter. They are experienced founders who have built and sold companies before.
Their previous startups include SCADAfence, which was bought by Honeywell, Portnox, which was sold to a private equity firm, and For-Each, which was acquired by Autodesk.
