Zscaler Reviews, Ratings & Features 2026 | Gartner Peer Insights

Gartner defines network security microsegmentation — also referred to as zero-trust network segmentation — as an effort that can create more granular and dynamic access policies than traditional network segmentation (often north-south traffic segmentation). It allows the insertion of a security policy between any two workloads in the same broadcast domain — with microsegmentation technologies narrowing fine-grained network zones down to individual assets and applications. Microsegmentation tools support the implementation of finer-grained zoning across public, private and hybrid cloud infrastructures. Cybersecurity leaders must understand the key features, use cases, and role of microsegmentation in their environment, as well as determine which model is the best fit for their needs.

I've installed this tool in my work laptop to eliminate old-school VPN solution. I am using linux based device and installation was not straightforward for me since it needs a lot of packages needs to be installed. Once the installation completed, the tool works seamlessly and it does not require that much of effort to connect to the company resources.
