Linx Security, an AI-native identity security and governance platform, has raised $50 million in Series B funding led by Insight Partners. The New York-based startup will use the funds to expand globally, scale enterprise go-to-market efforts, and accelerate research and development of its autonomous identity governance capabilities. Founded in 2023, Linx already manages millions of human, machine, and AI-agent identities for banks, healthcare providers, and Fortune 500 companies.

Why it matters

Identity has emerged as a primary attack vector for enterprises as they adopt cloud-native architectures and deploy more AI agents that operate autonomously across systems and data. Traditional identity governance tools were not built to continuously manage the growing complexity of dynamic, non-human identities, making Linx's AI-native approach an important innovation in enterprise cybersecurity.

The details

The $50 million Series B round brings Linx's total funding to $83 million. The company's AI-native platform continuously maps permissions, monitors risky behavior, and enforces policies at scale to govern human, machine, service, and AI-agent identities across cloud and SaaS environments. Linx's flagship autonomous agent, Linx Autopilot, is designed to proactively detect changes, remediate issues, and close identity-related gaps before they become breaches.

• Linx Security was founded in 2023.
• The $50 million Series B funding round was announced on April 17, 2026.

What’s next

Linx Security plans to use the $50 million in Series B funding to deepen its autonomous identity governance capabilities and expand coverage across hybrid, multi-cloud, and AI-heavy workloads.
