A Security Raises $37 million in Funding led by Lightspeed Venture Partners

The funding round was led by Lightspeed Venture Partners and Cyberstarts, with support from well-known angel investors, including Assaf Rapaport, CEO of Wiz, Yotam Segev, CEO of Cyera, and Cerca Partners.

A Security has built a platform that helps companies protect themselves from AI-powered cyberattacks. It finds security weaknesses and potential attack paths before hackers can take advantage of them.

The company plans to use the new investment to grow its business and further develop its autonomous security platform, helping organizations detect and fix vulnerabilities before they are exploited by malicious actors.

"We focus on agent-based attacks that operate end-to-end," said co-founder and CEO Yossi Torati. "Our goal is not just to identify vulnerabilities, but to close the entire attack chain before it can be exploited."

"One of our customers received intelligence from the FBI indicating they were vulnerable to a Russian cyber campaign," he said. "We identified the attack path before it could be exploited and helped prevent the attack."

"Recent advances in AI have ushered in a new era in cybersecurity," said Hila Zigman, Partner at Cyberstarts. "Attack capabilities that were once the exclusive domain of intelligence agencies and nation-states are becoming accessible to almost anyone. The defenses organizations rely on today were simply not designed to withstand autonomous AI agents that can identify and exploit vulnerabilities at an inhuman pace."

Founded in 2025 by Yossi Torati, Omer Gal, and Yuval Itzchakov, A Security is an Israeli cybersecurity company that helps businesses stay safe from cyberattacks, including threats that use artificial intelligence.

Its platform automatically scans a company’s systems, networks, and applications to find security weaknesses. It then identifies possible ways hackers could attack and helps companies fix those problems before any damage is done.

By using AI and automated security tools, A Security helps businesses strengthen their cybersecurity and stay one step ahead of cybercriminals.
