A Security raises $37M, exits stealth to fight weaponized AI attacks

Backing from Wiz and Cyera's CEOs signals that AI-driven attacks now require AI-driven defenders, not just human analysts.

• A Security emerged from stealth with $37 million in funding from Lightspeed Venture Partners and Cyberstarts, plus angel backing from Wiz CEO Assaf Rapaport and Cyera CEO Yotam Segev.
• Founded in 2025 by CEO Yossi Torati, CTO Yuval Itzchakov and CPO Omer Gull, the Tel Aviv startup builds an autonomous offensive security platform that hunts for exploitable attack paths.
• The platform is built to counter 'weaponized AI' — agentic attackers that can find, chain and exploit vulnerabilities across environments faster than manual security teams can respond.
• The round lands amid a burst of Israeli AI-security stealth launches in 2026, including Arrakis Security's $8M seed for AI-agent governance and Zenity's $125M Series C to police AI agents.
• As attackers automate exploit discovery with AI agents, defenders are racing to field autonomous offensive tools that operate at machine speed rather than relying on periodic manual pentests.
