Linx Security
Linx Security is a privately held cybersecurity company founded in 2023 and based in New York, New York. It offers an AI-native identity security and governance platform designed to help organizations manage the full identity lifecycle for human, non-human, and AI-agent identities. The core product, the Linx Identity Security platform, integrates with existing identity and access management (IAM) systems. It provides unified visibility, continuous risk detection, and autonomous remediation to reduce the identity attack surface and close compliance gaps. Key features include continuous monitoring of identity behavior, discovering and classifying identities, identifying misconfigurations, and automating identity lifecycle tasks like onboarding and offboarding. Linx focuses on real-time identity mapping and automated responses to enhance governance in the AI era, particularly addressing the rise of non-human identities. In terms of growth, Linx announced a $50 million Series B funding round in March 2026, led by Insight Partners, with participation from Cyberstarts and Index Ventures. The company previously emerged from stealth in 2024 with $33 million in funding.
