Linx Security is a New York-based cybersecurity company founded in 2023 that has raised $33M in funding. Its core product is an AI-driven, agentless identity security platform designed to give enterprises unified control over the full identity lifecycle - covering both human and non-human (machine) identities across cloud, SaaS, on-premise, and custom applications.
The platform integrates with an organisation's existing IAM stack without requiring agents, collecting, normalising, and correlating identity data from across the environment. It generates visual maps of the relationships between employees, their digital identities, and the applications they access, exposing hidden connections that can represent security risk. Core capabilities span identity security posture management (ISPM), governance, and remediation - including attack surface reduction and compliance gap remediation.
Linx Security targets identity, security, and IT operations teams at enterprise organisations. The platform addresses a recognised pattern in enterprise security: according to figures the company cites, 85% of breaches originate with a compromised identity. By providing a single layer of visibility and control across heterogeneous identity environments, the platform is positioned to reduce that exposure without requiring significant changes to existing infrastructure.
With 51–200 employees and a founding date of 2023, Linx Security is at an early but funded stage of growth, operating in a market that includes identity governance, access management, and emerging disciplines such as non-human identity security.
