Learn More About Zero Trust Networking Software

Zero Trust Networking Software Buying Insights at a Glance

Zero trust networking software enforces the principle of "never trust, always verify" by authenticating every access request, limiting lateral movement, and maintaining granular control over network resources. Instead of treating network perimeters as secure boundaries, these platforms assume breach and verify each connection attempt, whether from users, devices, or applications, before granting access. The result is a security architecture that feels more like continuous authentication and less like traditional perimeter defense.

Zero trust networking software has become central to modern cybersecurity strategies. Security teams rely on these platforms to implement application whitelisting, control network access without VPNs, enforce least-privilege policies, and maintain visibility across endpoints. In practice, the best zero trust networking software acts as the connective layer between identity management, endpoint security, and network access control workflows.

Based on G2 review data, users rate zero trust networking software strongly overall. Zero trust network products in the category have an average star rating of 4.60/5 and an average likelihood to recommend of 9.20/10. Ease-of-use metrics trend high across the category, with 6.32/7 for Ease of Use, 6.27/7 for Ease of Setup, and 6.38/7 for Quality of Support. These scores suggest that most security teams are able to adopt zero trust software relatively quickly once policies are configured.

The biggest buying pattern that appears across reviews is that teams evaluating zero trust network solutions are trying to balance two priorities at once: implementing comprehensive security controls and maintaining operational efficiency. Strong platforms typically succeed by combining application control, network segmentation, and user-friendly policy management that reduces manual oversight.

Common use cases include endpoint protection through application allow listing that blocks unauthorized software execution, secure remote access enabling users to connect to resources without traditional VPNs, lateral movement prevention restricting network traffic between systems, privilege management controlling admin rights and elevation requests, threat detection identifying malicious activity before execution, and compliance enforcement maintaining audit trails and access controls. Finance teams also rely on these platforms for DNS filtering, conditional access policies tied to device posture, and microsegmentation that isolates critical assets from the broader network.

Pricing for zero trust network companies usually scales with the number of protected endpoints, the number of enabled feature modules, managed detection and response services, and integration complexity. Entry-level plans typically start with basic application control and network filtering, while enterprise zero trust networking software offers advanced threat prevention, 24/7 SOC support, and zero trust network access (ZTNA) capabilities.

What I Often See in Zero Trust Networking Software

Pros: What I See Users Consistently Appreciating

  • Zero trust architecture prevents unauthorized application execution through default-deny policies

“I like the application control aspect of ThreatLocker Platform and the fact that it uses a Zero Trust method to prevent unknown execution or installation of software. With the application control, I get a wealth of information about what application is trying to run, where it’s running from, and what the application can do, such as talk to the internet or access other files. The zero trust method gives me full control, ensuring no application will run in my environment unless I approve of it first. I would say the initial setup, based on learning through their University, is pretty seamless, and ThreatLocker has an amazing team that helps make the process easier.” - Dino L., ThreatLocker Platform Review

  • Secure network access eliminating traditional VPN dependencies for remote users

“I appreciate how Zscaler Private Access secures remote connectivity for our hybrid workforce without the need for traditional VPNs, enabling safe access to internal applications from any location. I am impressed by the product's ability to noticeably reduce latency and enhance the overall user experience, all while upholding a robust security posture and compliance standards. Setting it up has been straightforward for me, thanks to the clear documentation and the support of an active community. 

I also value how users can connect directly to the specific applications they require, without exposing the entire network. The solution is lightweight and fast, removing the hassle of managing VPNs and their often sluggish tunnels. The admin console offers excellent visibility, and integration with identity providers like Azure is seamless. I find the cost of Zscaler Private Access to be reasonable and attractive, particularly for enterprises, and I appreciate its recognition as a market leader.” - Ritik S., Zscaler Private Access Review

  • Application whitelisting stops malware before it runs on endpoints

“I really like the strict application control and the ease of managing the ThreatLocker Platform. It ensures that only authorized applications can run, and the interface makes managing the application whitelist straightforward. The platform provides a solid and secure operation. Additionally, discovery and policy enforcement were easy, allowing for a quick standard of service.” - Mark A., ThreatLocker Platform Review

Cons: Where I See Many Platforms Falling Short

  • Complex policy configuration requiring extensive planning during initial deployment

“The initial setup and implementation can be a bit complex and time-consuming, especially for first-time users. Sometimes troubleshooting issues takes longer than expected. Also, the pricing feels on the higher side and some advanced features require additional configuration knowledge. Improving documentation and simplifying setup would make it easier for new teams.” - Deepak S., Zscaler Private Access Review

  • Steep learning curve navigating advanced features across multiple security modules

“While the core functionality is strong, the initial learning curve for configuring risk-based policies and understanding the ML-driven device classification can be a bit steep, especially for teams new to OT environments. Additionally, the product documentation could be more detailed regarding troubleshooting advanced detection scenarios. Pricing can also become a concern for smaller organizations with hybrid networks, particularly when scaling to multiple remote sites or factories.” - Verified User in Information Technology and Services, Palo Alto Networks IoT/OT Security Review

My Expert Takeaway on Zero Trust Networking Software in 2026

Review data suggests that zero trust networking software performs particularly well in areas that tend to drive long-term product adoption. The category averages 4.60 out of 5 stars, paired with a 9.20 out of 10 likelihood-to-recommend score, which indicates that most security teams see meaningful value from these platforms once they become part of the security workflow.

Where I see the biggest difference between average and high-performing security teams is how they use these tools beyond basic endpoint protection. The most successful teams treat zero trust software as a comprehensive security framework, not just as an application blocker. They actively leverage network control features, implement conditional access policies based on device posture, and use unified audit capabilities to track threats across their environment. That approach helps maintain stronger security postures and reduces time-to-detection when incidents occur.

I also notice stronger adoption patterns in industries where security threats are particularly intense, such as information technology services, computer and network security, healthcare, and financial services. In those environments, security teams often need to protect against sophisticated attacks while maintaining user productivity. Zero trust networking systems make it easier to enforce strict controls without losing visibility into endpoint activity.

Another clear trend in the data is that ease of deployment and support strongly influence adoption. Products with the highest recommendation scores tend to combine powerful security capabilities with learning modes that allow gradual rollout across organizations. Metrics like Ease of Setup (6.27/7) and Quality of Support (6.38/7) reinforce the idea that most teams can implement these platforms without significant operational friction, especially when vendors provide proactive engineering support.

If I were advising a team evaluating the best zero trust networking software, I would focus on three things early in the buying process: how easily security teams can configure policies without disrupting legitimate workflows, how effectively the platform provides visibility into blocked threats and access attempts, and how well it integrates with existing identity and endpoint management tools. The tools that perform best in those areas usually become foundational infrastructure for modern security operations.
