# Best Microsegmentation Software - Page 2

  *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)*

   Microsegmentation software is a network security solution designed to divide workloads and control them individually using policy-driven, application-level security. These tools isolate components of data centers and cloud workloads using network virtualization to deploy and protect them independently. This helps companies better visualize their assets and workloads to improve visibility, detection, and remediation time all while eliminating an attacker’s ability to move laterally throughout the network.

Companies use microsegmentation to both improve protection on individual workloads and improve network observability. When components of a data center or other environments are compromised without microsegmentation, attackers may be allowed to jump from one asset to the next, moving laterally throughout the network. With microsegmentation in place, the attack surface greatly reduces using granular security controls and policy-based security triggers to protect workloads even once attackers penetrate perimeter defenses.

Microsegmentation technology is often used to achieve zero trust security architecture, but should not be confused with [zero trust networking software](https://www.g2.com/categories/zero-trust-networking). While there is some overlap between the two categories, zero trust networking solutions are designed specifically to manage identities and control privileged access to internal applications or computing environments. While microsegmentation technology is also used for application-level security, the tools are more focused on creating secure zones, establishing security policies, and isolating workloads individually.

To qualify for inclusion in the Microsegmentation Software category, a product must:

- Utilize network virtualization to isolate application workloads
- Restrict lateral access across networks, data centers, and cloud environments
- Dynamically adjust policies to ensure consistent workload protection

### SecureW2 JoinNow

SecureW2 is a cloud-native authentication solution designed to enhance security by eliminating credential compromise through its innovative JoinNow Platform. This platform combines Dynamic Public Key Infrastructure (PKI) and Cloud RADIUS to facilitate real-time trust validation and continuous authentication for users accessing networks and applications. Each access request initiates an identity-based risk assessment, which determines the issuance of certificates and the corresponding access privileges. Once access is granted, the system continuously validates the compliance of devices, ensuring that only verified entities maintain their authorization. The JoinNow Platform caters to a diverse range of users, including K-12 and higher education institutions, mid-market businesses, and global enterprises. By providing scalable and resilient authentication solutions, SecureW2 addresses the unique security needs of various sectors without placing an additional burden on IT teams. The platform's ability to seamlessly integrate with existing identity providers, such as Entra ID (formerly Azure AD), Okta, and Google Workspace, allows organizations to implement adaptive, passwordless authentication without the need for complex upgrades or disruptions. SecureW2 effectively tackles several prevalent security challenges. Credential compromise remains a significant concern, as traditional passwords and multi-factor authentication (MFA) can be vulnerable. By utilizing certificate-based authentication, SecureW2 eliminates these risks entirely. Additionally, the platform addresses high operational overhead associated with managing legacy security systems by automating certificate issuance, revocation, and lifecycle management. This automation not only saves IT resources but also enhances visibility and control, providing real-time insights into authentication processes. Key features of SecureW2 include its agentless architecture, which eliminates software bloat while ensuring secure and frictionless authentication. The extensive policy engine allows organizations to create customized policies that are automatically enforced both before and after authentication. Continuous authentication adapts in real time, validating access dynamically based on evolving security conditions. Furthermore, the platform’s interoperability ensures compatibility with any identity provider, mobile device management (MDM) system, and security stack, making it a versatile choice for organizations looking to enhance their security posture. In summary, SecureW2 redefines authentication for modern businesses by ensuring that every access request is trust-validated. Its scalable, lightweight design enables rapid deployment and effortless scaling, allowing organizations to maintain robust security without the complexities and costs typically associated with traditional authentication solutions.

  ## What Are the Top-Rated Microsegmentation Software Products in 2026?
### 1. [Zero Networks Segment](https://www.g2.com/products/zero-networks-segment/reviews)
  Least privilege networking solution that prevents attacks from spreading and causing damage by automatically restricting network access to only what is normally needed, everything else goes through 2-step verification. With the addition of identity segmentation, Zero Networks is creating a new sphere of security capabilities. The combination of Zero’s network and identity segmentation capabilities redefines least privilege architecture, providing a level of protection that the market has never seen before. It allows security teams to control network device segmentation down to the port and protocol level and then layer complete control of user logon access by logon type – network, local, service, etc. As if that wasn’t enough, you can also add multi-factor authentication to any of those controls. You simply can’t do this using any other platform on the market today. Zero’s combined capabilities of network and identity segmentation are going to rewrite the playbook auditors and examiners use to assess security programs. Security teams need to take note and get ahead of the game.
