Elisity

Elisity provides identity-based microsegmentation solutions for enterprise networks spanning IT, IoT, and OT environments. The company's platform discovers and identifies every user, workload, and device on a network and correlates this information into its IdentityGraph system. This enables organizations to implement granular security policies based on identity rather than network topology.

The platform is designed for deployment within weeks without requiring network downtime or infrastructure rearchitecture. It leverages existing network switching infrastructure to enforce cloud-managed security policies in real-time. The solution automatically classifies devices and applies dynamic security policies that follow entities wherever they appear on the network, including ephemeral devices.

Elisity's approach addresses the limitations of legacy hardware and agent-based segmentation methods by mapping least-privilege policies directly to entities such as users, devices, applications, and workloads. The system continuously evaluates dynamic identity context to enforce access controls and contain threats, enabling organizations to prevent lateral movement across their networks.

The company serves Fortune 500 enterprises across regulated sectors including healthcare, manufacturing, and critical infrastructure. Founded in 2019 and headquartered in San Jose, California, Elisity has been recognized in Gartner reports including Cool Vendors in Cyber-Physical Systems Security and as a Representative Vendor in the Market Guide for Network Security Microsegmentation.

The company reports that over 83% of its enterprise customers achieve full segmentation rollout within 90 days.
