Appgate provides a high-performance Zero Trust Network Access (ZTNA) solution designed for complex hybrid and multi-cloud environments. The platform utilizes a Software-Defined Perimeter (SDP) architecture to create 1-to-1 encrypted tunnels, replacing legacy VPNs and hardware-based firewalls with identity-centric access controls. It features 'direct-routed' architecture to eliminate cloud latency bottlenecks and supports granular, attribute-based access control (ABAC) for both users and machine-to-machine communications.

Arista Networks is an industry leader in data-driven, client to cloud networking for large data center/AI, campus and routing environments. Arista's award-winning platforms deliver availability, agility, automation, analytics and security through an advanced network operating stack.

Blast is a preemptive cloud defense platform that shifts security from reactive monitoring to proactive prevention by leveraging native cloud infrastructure controls. It automates the implementation of guardrails that limit blast radius and enforce least-privileg access at the network and identity layers. By turning complex cloud configurations into preventive policies, it reduces the operational burden of manual remediation of misconfigurations.

ColorTokens' enterprise microsegmentation platform gives you the peace of mind of knowing that your computing environment is always prepared for a breach-by-design. With our Xshield platform, your critical business systems are protected by micro-perimeters, preventing the spread of malware or ransomware.

Elisity is a leap forward in network segmentation architecture. We enable CISOs to lead the enterprise effort to achieve Zero Trust maturity, proactively prevent security risks, and reduce network policy management complexity.

Extreme Networks ExtremeControl is a centralized Network Access Control (NAC) solution that enforces role-based access policies for wired, wireless LAN, and VPN users across multi-vendor switches and access points. It integrates authentication via 802.1X, Web-based, Kerberos, and RADIUS; vulnerability assessment for security posture checks; and location services to authorize endpoints. ExtremeControl engines detect devices by MAC/IP addresses, assign VLANs or policy roles on Extreme switches, support RFC 3580 quarantine, IPv6, Microsoft NAP, and TNC interoperability. Best for enterprises with Extreme Networks infrastructure seeking BYOD, IoT, and granular post-connect enforcement with assisted remediation.

Illumio is the first and only platform built for breach containment. Powered by an AI security graph. Enabling your Zero Trust journey.

We filter out noise and pinpoint critical risks, empowering organizations to safeguard every asset in the cloud, on-premises, or in SaaS environments.

Riptides appears to be an early-stage security vendor focused on Zero Trust / SASE, but publicly available product information is limited in the provided search results. Based on the category scope, a buyer would expect identity- and policy-based access control for users, devices, and applications, delivered through cloud-managed access points rather than a traditional VPN. If Riptides offers adjacent networking or security functions, they are not evident from the sources provided. This profile is therefore conservative and should be validated against Riptides’ own product documentation before procurement decisions.

TrueFort is a workload protection and microsegmentation vendor focused on blocking lateral movement across hybrid environments. Its platform builds behavioral baselines from workload telemetry, then generates segmentation policies and pushes enforcement to host firewalls or supported workload agents. The product is aimed at enterprises running mixed Windows, Linux, virtualized, container, Kubernetes, on-premises, and cloud workloads that need application-level segmentation without relying only on network-based controls. TrueFort is positioned as a specialist in zero-trust segmentation and runtime workload protection, with an emphasis on application behavior visibility, policy automation, and containment of ransomware, compromised credentials, and insider threats.

Unisys Stealth is a zero-trust microsegmentation platform that uses identity-based access controls and cryptographic cloaking to transform networks into segmented environments. The suite includes Stealth(core) for enforcement via micro-segmentation and encryption, and Stealth(aware) for network discovery and policy automation. Deployed across on-premises, AWS, and Azure environments, Stealth holds NSA NIAP certification and serves government and enterprise customers requiring east-west traffic isolation and dynamic workload protection.

Zentera Systems offers a Zero Trust Network Access (ZTNA) and microsegmentation platform centered around its Virtual Chamber technology. It provides a secure overlay for IT, OT, and AI infrastructure that requires no changes to underlying network architecture. It is often used to replace traditional VPNs and complex firewall-based segmentation with a more agile identity-centric access model.

Zero Networks is a microsegmentation vendor that automates network asset discovery, policy creation, and enforcement to stop lateral movement and reduce blast radius. Its Segment product is positioned for enterprises that want segmentation across on-premises, cloud, and OT/IoT environments without manually building firewall rules or deploying agents. The company also sells adjacent zero trust capabilities, but its microsegmentation offer centers on agentless, identity-driven segmentation with MFA-controlled access for workloads and unmanaged devices. It appears aimed at organizations replacing legacy segmentation projects with faster policy rollout and centralized control.
