Astrix Security nets $45M Series B led by Menlo and Anthropic to enhance AI era identity protection
The company helps enterprises close the Non-Human Identities blindspot, providing visibility into all non-human identities, and automatically detecting and remediating over-privileged, unnecessary and malicious access to prevent supply chain attacks and data leaks.
Cybersecurity startup Astrix Security has raised $45 million in a Series B funding round, bringing its total investment to $85 million since its inception. The funding round was led by Menlo Ventures through the Anthology Fund, a strategic partnership between Menlo and Anthropic, the AI company behind Claude. Other participants included Workday Ventures, the venture arm of the global HR software leader, alongside existing investors such as Bessemer Venture Partners, CRV, and F2 Venture Capital.
“All the funds raised will go directly into the company’s growth, and the company’s valuation has significantly increased with this round,” said Alon Jackson, co-founder and CEO of Astrix Security, in an interview with Calcalist.
Astrix Security was founded in 2021 by Jackson and CTO Idan Gour, both veterans of the Israel Defense Force 8200 military intelligence unit. The company helps enterprises close the Non-Human Identities (NHIs) blindspot, providing visibility into all non-human identities, and automatically detecting and remediating over-privileged, unnecessary and malicious access to prevent supply chain attacks and data leaks.
Astrix has experienced remarkable growth since its $25 million Series A funding last year, expanding its revenue fivefold and tripling its headcount to 80 employees. Its client roster includes Fortune 500 companies and notable names such as Workday, NetApp, Priceline, and Figma.
Discussing the company’s trajectory, Jackson explained that Menlo Ventures’ extensive experience in scaling cybersecurity companies was a key factor in the partnership. “Menlo Ventures knows how to take a cyber company like ours to $100 million in sales. Their partnership with Anthropic also aligns with our goal of securely integrating AI into organizations. Workday, which is both an investor and a client, further validates our approach.”
Jackson detailed Astrix’s plans to double its workforce in the United States and Europe, emphasizing the demand for its solutions as companies increasingly adopt AI in their operations. “Many organizations want to integrate AI into every aspect of their work, but they need robust security. Our platform ensures that AI agents are not only effective but also secure and properly managed.”
Jackson highlighted the growing importance of addressing this issue of NHIs: “Non-human identities have been central to some of the most notable cyberattacks in the past year, including incidents reported by Microsoft and Okta. This problem is only going to grow as AI adoption increases. Organizations need to know how to monitor and manage AI agents to prevent vulnerabilities.”
Astrix Security’s platform enables companies to securely connect third-party and in-house applications to their corporate digital assets while preventing malicious intrusions and supply chain attacks. It’s a solution designed to fill the gap left by traditional security tools that primarily manage human identities.
On the company’s vision, Jackson said, “We didn’t raise this round to sell the company within a year or two. We’re building a company that can lead in a highly competitive market. In cybersecurity, it’s often winner-takes-all, and we intend to be that winner. It’s entirely possible to build a significant and impactful company here in Israel.”
