Best Microsegmentation Software in 2026

Illumio Core provides granular control over network communication, reducing the attack surface and preventing lateral movement of threats. It visualizes application dependencies and creates security policies that adapt to changes in your environment, enhancing security posture across hybrid IT.

VMware NSX Data Center delivers a complete L2-L7 networking and security virtualization platform. It enables microsegmentation by distributing security functions throughout the virtualized network, providing granular protection for individual workloads and applications.

Palo Alto Networks' approach to microsegmentation is part of their broader Zero Trust framework, focusing on preventing unauthorized access and limiting lateral movement. It leverages network security platforms to enforce granular policies based on user, application, and content identity.

Cisco Tetration provides pervasive visibility across data centers and multi-cloud environments, enabling automated policy enforcement and microsegmentation. It uses behavioral analytics and machine learning to understand application dependencies and generate granular security policies.

Guardicore Centra offers deep visibility into data center and cloud flows, enabling precise microsegmentation and breach detection. It identifies and stops lateral movement with flexible policies and integrates deception technology to detect advanced threats.

Akamai Guardicore Segmentation, formerly Guardicore Centra, provides robust microsegmentation for on-premises, cloud, and hybrid environments. It offers deep visibility, automated policy recommendations, and real-time threat detection to prevent unauthorized lateral movement.

Aporeto, now part of Palo Alto Networks, delivers cloud-native identity-based microsegmentation for containers and microservices. It enforces granular policies based on workload identity, securing application communications across any cloud or infrastructure.

While not solely a microsegmentation tool, HyTrust DataControl (now part of VMware) enables granular encryption and access controls for virtual machines. This contributes to microsegmentation by restricting access at the data layer, complementing network-based segmentation.

Unisys Stealth uses identity-based microsegmentation to create secure communities of interest, cloaking endpoints and preventing unauthorized access. It establishes trusted zones for communication, reducing the attack surface and protecting sensitive data in hybrid environments.

Versa Networks' SASE platform incorporates microsegmentation capabilities as part of its unified network and security services. It enables granular policy enforcement at the edge, securing users, devices, and applications across distributed environments and clouds.

Arista Microsegmentation provides fine-grained security policies and enforcement for applications and workloads across data centers and cloud environments. It helps reduce the attack surface and prevent lateral movement of threats by isolating critical assets and controlling communication.

Zscaler Workload Segmentation extends zero trust principles to protect applications and workloads wherever they reside. It offers identity-based segmentation, preventing unauthorized access and lateral threat movement within hybrid and multi-cloud environments, enhancing overall security posture.

Forcepoint Adaptive Micro-segmentation delivers intelligent, context-aware segmentation that adapts to user behavior and data sensitivity. It provides granular control over network access, protecting critical applications and data from internal and external threats by continuously assessing risk.

Juniper Networks vSRX Virtual Firewall provides robust security for virtualized and cloud environments, enabling micro-segmentation capabilities. It offers advanced threat prevention, intrusion detection, and granular policy enforcement to protect individual workloads and applications from network-based attacks.

Cyxtera AppGate SDP (Software-Defined Perimeter) implements a zero trust approach to micro-segmentation, dynamically creating secure, one-to-one connections between users and the resources they need. It minimizes the attack surface by making applications invisible to unauthorized users, regardless of location.
