Neo Security Raises Over $50 Million in Latest Funding Round Backed by Andreessen Horowitz

Neo Security, a stealth-mode cybersecurity startup founded in 2025 by former executives of Israeli-American firm SentinelOne, has secured more than $50 million in its latest funding round. The company’s founding team includes CEO Nicholas Warner, previously SentinelOne’s president and COO; Chief Product Officer Shlomi Salem, former VP of research at SentinelOne; and Eran Shirazi, ex-VP of Research at Any.do. Neo Security initially raised $25 million in 2025, led by major American venture capital firms Andreessen Horowitz and Marlin Ventures. The recent round added the American Kraft VC fund to its existing investors.

Neo Security is reportedly developing a platform designed to bridge security solutions across organizational endpoints, networks, and identities. Earlier this year, the company published research exposing a massive data leak from a major accounting firm, revealing sensitive information including schemas, API keys, and authentication tokens.

Andreessen Horowitz has notably increased its presence in Israel, completing at least seven investments in Israeli startups in 2024 alone, expanding beyond its traditional Silicon Valley focus. The firm was a significant beneficiary of the $32 billion Google acquisition of Wiz and currently prioritizes investments in cybersecurity and artificial intelligence companies.
