§ Private Profile · San Jose, CA, USA
Software platform providing identity-based microsegmentation for enterprise Zero Trust network security across IT, IoT, and OT infrastructure.
Based in San Jose, California, Elisity provides identity-based microsegmentation software that enables enterprises to implement Zero Trust network security architectures without requiring hardware or network changes. The platform utilizes artificial intelligence and machine learning to automate asset discovery and policy enforcement across IT, IoT, and OT devices for clients in healthcare, manufacturing, and energy. The company experienced a fivefold surge in active policies during the fourth quarter of 2024, with organizations implementing an average of over 1,000 active segmentation policies. Enterprise deployments average 14 days to the first active policy, and over 83 percent of Fortune 500 customers implement critical security protocols across their infrastructure within 90 days. Elisity is backed by investors including TCV and Chevron Technology Ventures, and its leadership includes veterans from Cisco, Palo Alto Networks, and McAfee. The company was founded in 2018.
Elisity has raised $78.5M across 3 funding rounds.

Elisity is a cybersecurity company that builds an AI-powered, identity-based microsegmentation platform to enable Zero Trust security. It serves enterprises, including Fortune 500 companies, government agencies, healthcare organizations, and industrial sectors with IT, IoT, OT, and IoMT devices, solving the problem of network blind spots, lateral movement by attackers, and complex legacy segmentation by providing rapid discovery, classification, and enforcement of least-privilege policies without agents, hardware, or network changes.[1][2][3][4][5][7]
The platform deploys in days to weeks—averaging 14 days to first active policy—using existing switching infrastructure (e.g., Cisco, Juniper, Aruba, Arista) via Virtual Edge technology, instantly discovering 100% of devices and applying dynamic, cloud-managed policies that persist across networks.[3][4][5][6] Elisity has shown strong growth momentum, with double-digit year-over-year customer traction in 2024, a 5x surge in active policies in Q4 2024, and rapid deployments like GSK adding three sites weekly.[3][5]
Elisity was founded in 2019 (with some sources noting roots since 2018) by a team with over 25 years of experience designing, building, marketing, and selling network and security products.[1][2][3] The idea emerged to address shortcomings in traditional network segmentation amid rising cloud adoption, mobility, and connected devices, aiming to untangle security from underlying network constructs and leap forward in architecture for Zero Trust maturity.[1][2]
Early traction came from its agentless, downtime-free design that leverages existing infrastructure for rapid implementation, quickly gaining Fortune 500 customers and a global employee footprint. The company is supported by a renowned Board of Directors and Advisors with deep tech leadership experience, fueling its focus on proactive risk prevention and complexity reduction.[2][3]
Elisity rides the Zero Trust trend, accelerating maturity by replacing implicit-trust legacy architectures with scalable microsegmentation amid rising ransomware, malware, and compliance mandates like HIPAA 2025 network segmentation and IEC 62443 for OT.[3][5][7] Timing is ideal as enterprises converge IT/OT/IoT environments, face east-west attack surges in cloud/microservices, and seek to maximize existing infrastructure investments without rip-and-replace overhauls.[2][5][6]
Market forces favoring Elisity include explosive IoT/OT growth, shadow IT proliferation, and budget constraints pushing agentless solutions—positioning it ahead of hardware-heavy competitors. It influences the ecosystem by enabling unified IT/Security/IoT operations, faster compliance, and ecosystem integrations, helping organizations like GSK scale globally while reducing complexity.[3][5][6]
Elisity is poised for continued acceleration into 2026, building on 2024's record momentum with expanded adoption in healthcare (HIPAA-driven), industrial OT (IEC 62443), and government sectors needing rapid, compliant segmentation.[5][6][7] Trends like AI-enhanced adaptive policies, multi-cloud/OT convergence, and ransomware blast-radius reduction will shape its path, potentially driving further customer growth and policy surges as enterprises prioritize resilient, infrastructure-agnostic Zero Trust.
Its influence may evolve by setting standards for "light and secure" network control on unmanaged devices, tying back to its core strength: redefining security access simply and scalably in a hyper-connected world.[9][2]
Elisity has raised $78.5M across 3 funding rounds. Most recently, it raised $45.0M Series B in April 2024.
