Selecting the right microsegmentation solution is crucial to achieving these benefits and ensuring a secure, resilient, and efficient network.

The variety of microsegmentation solutions available in the market can make it challenging to identify the best fit for your organization's unique requirements. This blog post aims to guide you through the process of evaluating microsegmentation solutions by providing an overview of the essential factors to consider. We will discuss the critical features and functionalities that a microsegmentation solution should offer, the pros and cons of building your solution versus opting for a third-party provider, and best practices for deploying a microsegmentation solution. By considering these factors, you can make an informed decision that will set your organization on the path to enhanced network security and performance.

Microsegmentation Platform Architecture Types

Before evaluating specific microsegmentation platforms, it is important to understand the four primary architecture approaches available in the market today. Each model has distinct trade-offs in deployment speed, coverage, and operational complexity.

Agent-Based Platforms

Agent-based microsegmentation platforms require installing software agents on every endpoint, server, or workload. These agents enforce policies directly on the host operating system. While this approach provides deep workload-level visibility, it introduces significant deployment overhead, ongoing agent management, and cannot protect devices that do not support software installation (such as OT sensors, IoT devices, and legacy systems).

Agentless, Network-Native Platforms

Agentless microsegmentation platforms enforce policies through the existing network infrastructure rather than requiring endpoint software. This approach enables rapid deployment (often days instead of months), eliminates agent lifecycle management, and extends protection to unmanaged devices including OT, IoT, and medical equipment. Elisity is a leading example of this architecture, using identity-based policies enforced at the network switch level.

Hypervisor-Based Platforms

Hypervisor-based microsegmentation platforms operate at the virtual network layer, enforcing policies between virtual machines within a data center. While effective in fully virtualized environments, this approach is limited to workloads running on supported hypervisors and does not extend to physical endpoints, IoT devices, or multi-cloud environments without additional tooling.

Cloud-Native Platforms

Cloud-native microsegmentation platforms leverage cloud provider APIs and constructs (such as security groups, network policies, and service meshes) to enforce segmentation within cloud environments. These tools work well for cloud workloads but often lack visibility and control over on-premises infrastructure, creating gaps in hybrid environments.

Understanding these architecture types is the first step toward selecting a microsegmentation platform that aligns with your environment, security goals, and operational capacity.
