Company Overview
About Elisity
Elisity is a cybersecurity company founded in 2019 and headquartered in San Jose, California, that provides AI-powered Zero Trust network access and identity-based microsegmentation for enterprise organizations with complex hybrid environments. The company's platform enables organizations to define and enforce granular security policies based on the identity of users and devices — rather than network segments or IP addresses — without requiring changes to existing network infrastructure. This identity-centric approach to microsegmentation is designed to dramatically reduce the attack surface available to lateral movement by malicious actors, containing breaches that penetrate the network perimeter.
Business Model & Competitive Advantage
Elisity's platform is particularly focused on environments that combine traditional IT infrastructure with operational technology (OT) systems, IoT devices, and medical devices — environments where legacy equipment cannot run traditional endpoint security agents and where the risk of network segmentation failures has direct physical or safety consequences. Healthcare (protecting medical devices and patient data) and industrial/manufacturing (OT network security) are key verticals where Elisity has developed specific use cases. The platform's policy automation capabilities — using AI to analyze device behavior and recommend appropriate segmentation policies — reduce the manual configuration burden that has historically made microsegmentation difficult to implement at scale.
Competitive Landscape 2025–2026
The company raised a $31 million Series B in 2024, demonstrating continued investor confidence in its approach to a market where Zero Trust network access and microsegmentation have moved from aspirational concepts to board-level security priorities following high-profile ransomware and supply chain attacks. Elisity competes with microsegmentation vendors including Illumio, Guardicore (acquired by Akamai), and Xilica, as well as broader ZTNA vendors including Zscaler, Palo Alto Networks Prisma Access, and Cloudflare One.
