What it sells: Zero Networks

What Identity Segmentation does[1][2][8]
Zero restricts privileged account access to operational needs only to remove the risk of credential theft. Zero learns all logon activities, account behaviors, and asset access patterns to create automated policies based on legitimate behavior. Service, admin, and agent accounts are restricted to pre-approved assets and logon types, so lateral movement and unauthorized access are blocked even if credentials get stolen. Admins can only log on to pre-approved assets after MFA.
What Secure Remote Access does[1][2][5][7][12]
Zero combines the speed of VPN with the security of ZTNA to connect remote employees and vendors. Policies allow user access to all or pre-approved apps and services. Zero remote access enforces access controls, tracks user activity, creates audit trails, and enforces MFA user authentication.
What RPC Firewall does[2][10]
RPC Firewall allows only legitimate and crucial RPC traffic and blocks unwarranted operations. RPC Firewall addresses threats including lateral movement, remote code execution, internal discovery, and relay attacks. Domain Controllers, Certificate Authorities, and Federation Services are essential services covered by the solution.

About Illumio

Illumio is a security company that sells the Illumio Breach Containment Platform, which includes Illumio Insights and Illumio Segmentation for hybrid and multi-cloud environments.[1][7]

Illumio says it addresses lateral movement, the workload-to-workload movement inside an environment. Illumio says cloud-native controls were not built to cover this east-west traffic, and that each cloud provider has its own console, so there is no single policy view across Azure, AWS, GCP and OCI.[8]

Illumio Insights is described on the Illumio site as a tool to identify lateral movement, detect attacks, and stop breaches at cloud scale. Illumio says it is powered by an AI teammate called Insights Agent, which supports prioritisation of threats with context-rich analysis, deep observability, and one-click containment.[1]

Illumio Segmentation is described as a way to secure critical assets, workloads, and devices across a hybrid, multi-cloud environment. Illumio says it lets customers see risk, set policy, and prevent lateral movement.

For cloud security, Illumio says its platform works across the data center, endpoints, containers, Azure, AWS, GCP, and OCI, with or without an agent. Illumio says policy is label-based and follows the workload through auto-scaling, redeployment, and IP changes. Illumio says Draft-view shows which connections a rule would change before it goes live.[8]

Illumio publishes pages for several industries. For financial services, Illumio says it helps secure systems from core banking to mobile apps. For energy and utilities, Illumio says it helps operators identify risks, detect threats, and contain breaches across IT and OT systems. For healthcare, Illumio says it blocks the spread of attacks across IT, OT, and medical devices. Illumio also has pages for government, manufacturing, telecom, and small and midsize businesses.[9][10][11][15]

For compliance, Illumio names GDPR, HIPAA, PCI DSS, and DORA, and says it can generate audit-ready evidence of segmentation, policy enforcement, and breach containment efforts. Illumio says Microsoft deploys Illumio across its entire corporate IT environment.[3][12][13][14][16]
