Linx Security

Linx Security builds an AI-native identity security platform that discovers, maps, and governs both human and non-human identities across an organization’s cloud, SaaS, on-prem, and custom applications. The platform constructs an identity graph that connects accounts, entitlements, and access relationships, then uses that graph to score risk, flag anomalous or excessive access, and surface gaps that traditional identity governance and administration (IGA) tools tend to miss, particularly around service accounts, API keys, and other machine identities.

Founded in 2023 in Tel Aviv by CEO Israel Duanis (previously of Check Point Software) and CPO Niv Goldenberg (previously of Transmit Security and Adallom), Linx emerged from stealth in mid-2024 with a $33 million combined seed and Series A round led by Index Ventures and Cyberstarts, with angel backing from Wiz founders Assaf Rappaport and Yinon Costica. The company has since closed a $50 million Series B, giving it substantial runway to build out automation and remediation workflows on top of its identity graph.

The company’s pitch centers on closing the gap between finding identity risk and fixing it: rather than just reporting on excessive entitlements or stale accounts, Linx aims to automate remediation and access-review workflows directly. That focus on non-human and AI-agent identity sprawl – a fast-growing blind spot as organizations deploy more service accounts, API integrations, and autonomous agents – is a differentiator versus legacy IGA vendors built primarily around human workforce access.
