Linx Security vs Microsoft Sentinel
Side-by-side comparison of AI visibility scores, market position, and capabilities
AI-native identity security platform governing human, non-human, and AI agent identities. Raised $50M Series B (Insight Partners, March 2026); $100M+ total raised; targets enterprise NHI sprawl and AI agent credential risks.
About
Linx Security is an AI-native identity security company that addresses one of the fastest-growing attack surfaces in enterprise security: the explosion of non-human identities (NHIs) and AI agent credentials that now outnumber human user accounts in most large organizations. Founded to tackle identity governance for the AI era, Linx recognizes that traditional Identity and Access Management (IAM) tools were designed around human employees and cannot effectively govern the service accounts, API keys, OAuth tokens, and AI agent identities that now permeate enterprise environments. A single misconfigured NHI can become an attacker's entry point to critical systems.\n\nLinx's platform provides unified visibility and governance across human identities, non-human identities, and AI agent credentials in a single control plane. It continuously discovers, classifies, and monitors identity relationships and access permissions across cloud environments, SaaS applications, and internal systems—surfacing misconfigurations, over-privileged accounts, and anomalous access patterns that traditional tools miss. As enterprises deploy autonomous AI agents that access APIs, databases, and sensitive systems, Linx's ability to govern AI agent identities with the same rigor as human identities becomes a critical security capability.\n\nIn 2026, Linx Security raised a $50M Series B led by Insight Partners, one of the most active investors in cybersecurity. This funding validates Linx's market thesis and provides capital to expand its platform capabilities and enterprise sales motion. The timing is significant: as AI agent deployments accelerate across enterprises, the NHI governance market is growing rapidly. Linx competes in the identity security space alongside established vendors like CyberArk and SailPoint, but its AI-native architecture and NHI-first focus give it a product advantage for the security challenges that matter most in 2025-2026.
Microsoft's cloud-native SIEM/SOAR platform with AI-powered threat detection and Copilot integration; part of Microsoft's $20B+ security business competing with Splunk/Cisco and IBM QRadar.
