Linx Security has raised $50 million in a Series B round led by Insight Partners, with continued backing from Cyberstarts and Index Ventures. The round brings the company's total funding to $83 million and signals strong institutional confidence in identity governance as one of enterprise security's most urgent problems. The New York-based startup has already secured multimillion-dollar contracts with banks, healthcare providers, and Fortune 500 companies, managing millions of identities across those organizations.
Insight Partners manages over $90 billion in regulatory assets and has backed more than 875 companies globally. The firm's involvement reflects a broader bet that identity governance is shifting from a compliance footnote to a genuine security priority.
The explosion of machine identities inside organizations is what makes this moment significant. Enterprises running on cloud infrastructure, automation pipelines, and AI tools now operate environments where machines, service accounts, and AI agents outnumber human employees by roughly 80 to 1. Traditional identity tools were simply not built for this. They were designed for slower, more predictable environments where periodic reviews and manual oversight were sufficient. Today they are not.
Nearly 90% of security incidents involve identity-related failures. Security teams are left with fragmented visibility, slow response cycles, and limited ability to act on risk as it emerges.
"Identity governance has shifted from a back-office compliance function to a core pillar of enterprise security," said Israel Duanis, CEO and co-founder of Linx Security. "This funding allows us to scale faster and meet the growing demand from organizations that need real-time visibility and control over every kind of identity operating in their environment."
The new capital will go toward expanding Linx's global footprint, scaling its enterprise sales operation, and accelerating product development around autonomous identity governance. The priority is reaching more organizations faster, particularly those running complex, AI-heavy environments where identity risk compounds quickly.
A significant part of that development effort is already underway. Linx recently launched Linx Autopilot, the first autonomous AI agent built specifically for identity governance. Rather than relying on scheduled audits or manual intervention, Autopilot monitors identity activity in real time, identifies meaningful changes, and either resolves issues automatically or escalates when human review is needed. It covers human accounts, machine identities, and AI agents within a single continuous workflow, reducing the operational load on security teams while improving response speed.
Linx Security was founded in 2023 by Israel Duanis and Niv Goldenberg, both cybersecurity veterans, and has grown to 100 people in just two years. Its core product is an AI-native platform that maps, monitors, and governs every identity across an enterprise, replacing periodic manual reviews with continuous detection and automated remediation.
What separates Linx from older identity governance tools is the scope of what it covers. Most legacy platforms were designed around human users. Linx treats human accounts, service accounts, machine identities, and AI agents as part of a single unified surface, applying the same governance logic across all of them.
The company has built its client base across identity-intensive sectors including banking, healthcare, and large enterprise. Its contracts are multimillion-dollar in scale, suggesting the platform is being adopted not as a point solution but as infrastructure.
Cyberstarts and Index Ventures, both early backers, continued their participation in this round alongside Insight Partners.
Gili Raanan, Founding Partner at Cyberstarts, explained the firm's thesis: "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 organizations, turning identity governance from a back-office compliance task into a board-level risk. Linx is building the platform to govern that new reality."
Teddie Wardi, Managing Director at Insight Partners, added: "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."
