Who it fits
Elisity also addresses manufacturers with connected IT and OT networks, and enterprises with users, devices and workloads to contain. Financial institutions that connect branch services, corporate systems and acquired environments are another group Elisity describes. Elisity positions its enforcement as running through supported network infrastructure rather than software agents on the assets being protected.FireMon's products are aimed at organizations that manage rules and prove compliance across on-premises, virtual, and cloud network controls. FireMon describes buyers who run multi-vendor firewalls, cloud networks, and microsegmentation environments. FireMon is channel-only by design, and resellers, MSSPs, GSIs, distributors, and technology partners can bring FireMon into the architectures and services they already deliver.From its own pages, Illumio sells mainly to organisations running hybrid and multi-cloud environments. Illumio publishes pages for financial services, energy and utilities, healthcare, government, manufacturing, telecom, and small and midsize businesses. Illumio says it helps financial institutions, utility operators, and telecom providers. Illumio also says its platform is built to be fast, simple, and flexible for small and midsize businesses.The pages give little detail on buyers. They do not name customers, industries or organisation sizes the company serves. What is described are product and solution menu labels, not statements about who buys them. Based on what is available, no reliable fit description can be given.

About Elisity

Elisity sells identity-based microsegmentation for the network a customer already runs. Elisity connects identity and risk context across users, devices, workloads and AI agents. Elisity enforces least-privilege policy through a customer's existing network infrastructure. Elisity has an agreement to join IonQ.[1][3]

Elisity Cloud Control Center is the cloud-delivered console for visibility, policy and reporting. Elisity uses AWS to host Cloud Control Center. Elisity IdentityGraph combines network observations with context from identity, endpoint, CMDB, IoT and cloud tools to build one record per asset. Elisity Intelligence proposes device classifications, Policy Groups and policies with the evidence behind each suggestion. The Elisity Assistant answers plain-language questions about devices, traffic and policies inside Cloud Control Center.[1][4]

Elisity Virtual Edge connects a customer's network infrastructure to Cloud Control Center. Elisity Virtual Edge sits outside the data path and programs policy into the data plane. Elisity enforces identity-based policy through supported wired network infrastructure from Cisco, Arista, Juniper, HPE Aruba and Hirschmann. Elisity enforces identity-based policy through Cisco Catalyst 9800 wireless controllers. Elisity shares Policy Group membership with Palo Alto Networks firewalls as Dynamic Address Groups. Protected devices do not need an Elisity endpoint agent. On supported network infrastructure, the last configuration stays in place if a plant loses its connection to the cloud.[1][5][6]

Elisity lets administrators simulate policy against observed traffic before enforcing it. Suggested policies from Elisity Intelligence start in simulation, and administrators decide what moves to enforcement. Elisity flags Allow policies that have carried no traffic over a review window. Elisity IdentityGraph brings AWS and Azure workloads in alongside users and devices, with cloud tags and instance details available as policy context. Elisity applies access policy to the device or workload running an AI agent. Elisity enforces through the network, outside the agent's runtime. Elisity is extending IdentityGraph to additional non-human identities, including service accounts and machine credentials.[1][3]

Elisity Open Connector is for custom API sources, and Custom Connector is for a customer's own asset inventory. The Zero Trust Posture Score rates segmentation posture from 0 to 100, refreshed daily. Scheduled Snapshot reports map Elisity segmentation and policy evidence to selected IEC 62443, HIPAA Security Rule and PCI DSS requirements.[1]

Elisity helps healthcare teams contain lateral movement across clinical networks and medical devices. Elisity helps manufacturers contain lateral movement across connected IT and OT networks. Elisity helps enterprises contain lateral movement across users, devices and workloads, including those running AI agents. Elisity describes financial institutions as needing to connect branch services, corporate systems and acquired environments while limiting what a compromised asset can reach. Main Line Health deploys Elisity microsegmentation enterprise-wide across its Cisco infrastructure with Armis integration.[1][3][5][6][7][9]
