Elisity

Elisity is an identity-based microsegmentation platform that enables enterprise organizations to implement Zero Trust network security without agents, hardware changes, or network downtime. Founded in 2019 in San Jose, California, Elisity's IdentityGraph technology automatically discovers and classifies all users, workloads, and devices across enterprise networks — including IoT and OT assets — and enforces dynamic, least-privilege access policies based on identity and behavioral context. The platform ingests metadata from existing security tools such as CrowdStrike, Active Directory, and Armis to automate policy creation and prevent lateral movement from ransomware and cyberattacks. Elisity is trusted by organizations in healthcare, manufacturing, and commercial enterprise. The company has raised $72.6M across four funding rounds, including a $37M Series B in 2024 led by Insight Partners, and was named a Gartner Cool Vendor in Cyber-Physical Systems Security in 2025.
