Linx Security, an identity security and governance platform, has raised $50m in a Series B funding round led by global software investor Insight Partners, with continued participation from existing backers Cyberstarts and Index Ventures.
The round brings the company’s total funding to $83m, and comes as identity-related failures are emerging as one of enterprise security’s most pressing challenges. The 100-person startup has already secured multimillion-dollar contracts with banks, healthcare companies, and Fortune 500 firms, with its platform governing millions of identities across those organisations.
Founded in 2023 by cybersecurity veterans Israel Duanis and Niv Goldenberg, Linx Security offers an AI-native platform that continuously maps, monitors, and governs all identities across an enterprise — spanning employees, machines, services, and AI agents.
The company says the number of non-human identities now outpaces human ones by roughly 80 to 1, driven by enterprise adoption of cloud infrastructure, automation, and artificial intelligence. Traditional identity governance tools, built for smaller and more static environments, have struggled to adapt, leaving security teams with limited visibility and growing exposure at a time when close to 90% of security incidents involve identity-related failures.
The fresh capital will be used to expand Linx’s global footprint, scale its enterprise go-to-market operations, and accelerate product development focused on autonomous identity governance. A key part of that roadmap is Linx Autopilot, the company’s recently launched autonomous AI agent, which it describes as the first of its kind designed specifically for identity governance.
Rather than relying on manual oversight and periodic reviews, Autopilot continuously monitors identity activity, detects changes in real time, and either resolves issues automatically or escalates them when necessary — covering human, machine, and agent identities alike.
Linx Security CEO and co-founder Israel Duanis said, “Identity governance has shifted from a back-office compliance function to a core pillar of enterprise security. This funding allows us to scale faster and meet the growing demand from organisations that need real-time visibility and control over every kind of identity operating in their environment.”
Insight Partners managing director Teddie Wardi said, “Linx is reimagining IGA architecture to tackle the emerging problem of agent governance. The company’s AI-first approach, along with the introduction of Linx Autopilot, well positions Linx in this critical category and we’re thrilled to partner on this journey.”
Cyberstarts founding partner Gili Raanan said, “We backed Linx at inception because we believe identity would become the core control layer of modern security. AI agents are rapidly expanding the number of identities operating inside organisations, turning identity governance from a back-office compliance task into a board-level risk. Linx is building the platform to govern that new reality.”
