Elisity

Elisity is a privately held cybersecurity company that specializes in identity-based microsegmentation for enterprise networks. The company was founded in 2018 by a team of networking and security veterans, including Chandra Shekhar Pandey and Sriram Sitaraman, and is headquartered in San Jose, California. Elisity's platform, Cognitive Trust, uses AI and machine learning to discover, profile, and segment all endpoints and workloads—including IT, IoT, and OT devices—without the need for agents or network changes. This approach enables organizations to enforce least-privilege access policies and reduce attack surface across campus, data center, and cloud environments. Elisity targets large enterprises in sectors such as manufacturing, healthcare, financial services, and critical infrastructure, where legacy segmentation methods are often complex and costly. The company's solution integrates with existing network infrastructure and security tools, providing visibility and policy enforcement through a single pane of glass. Elisity has raised venture funding from investors including Insight Partners and has been recognized for its innovative approach to zero trust security. As a private company, Elisity does not disclose detailed financials, but it continues to expand its customer base and partnerships, positioning itself as a key player in the growing microsegmentation market.

Elisity was founded in 2018 by Chandra Shekhar Pandey, Sriram Sitaraman, and other networking and security veterans. The company emerged from stealth in 2020 with its Cognitive Trust platform, which introduced agentless identity-based microsegmentation for enterprise networks. In 2021, Elisity raised a $26 million Series A funding round led by Insight Partners. The company has continued to develop its platform, adding support for OT and IoT environments and forming partnerships with network infrastructure vendors. Elisity's technology is designed to simplify segmentation and zero trust adoption for large enterprises.
