A New York-based autonomous offensive security startup named A has raised $37 million in funding led by Lightspeed Venture Partners, with participation from Cyberstarts and angel investors including Wiz CEO Assaf Rappaport and Cyera CEO Yotam Segev, Fortune reported. The startup emerged from stealth this week, offering an AI-powered platform that continuously tests and improves its customers’ cybersecurity defenses.
The startup’s AI system autonomously attempts to breach its clients’ networks, identifying real attack paths and enabling fixes before malicious hackers can exploit them. This approach contrasts with traditional mock cyberattacks that cost about $30,000 and take two weeks but provide outdated insights. A’s CEO and cofounder Yossi Torati, who has extensive experience in incident response and cyber defense, said the industry faces a meltdown due to the rise of AI models like Anthropic’s Mythos, which revealed thousands of zero-day vulnerabilities earlier this year.
The funding round comes amid growing concerns over AI-driven cyber threats. Anthropic’s Mythos model, unveiled in April, autonomously discovered security flaws across major operating systems and browsers, lowering the barrier for attackers. Torati warned that AI democratizes hacking capabilities, allowing even unsophisticated users to launch attacks previously limited to nation-state actors. The startup’s founders bring expertise from Israeli cybersecurity firms and military intelligence units, positioning the company to address emerging risks in the sector.
The $37 million funding will support the startup’s expansion and product development as it aims to safeguard organizations against AI-enabled cyberattacks. The company’s emergence follows Anthropic’s Mythos release on April 8, which significantly shifted the cybersecurity landscape by exposing new vulnerabilities.
