Best Zero Trust Security Software for Linux

If you’ve ever dealt with slow VPNs, or clunky ZTNA agents that degrade app performance, you’re not alone. Many IT teams are stuck balancing security with usability—and often end up sacrificing both. Here is a different approach. The high-performance ZTNA service that is part of a personal SASE solution from Cloudbrink can upgrade or replace traditional VPNs while fixing the performance and complexity that come from other vendors in the ZTNA and SASE space. Built as a software-only service, Cloudbrink delivers sub-20ms latency and 1Gbps+ speeds per user using dynamically deployed FAST edges and a proprietary protocol that recovers packet loss before it impacts the app. Security isn’t bolted on—it’s built in. With mutual TLS 1.3, short-lived certs, and no exposed IPs, Cloudbrink provides real zero trust without making users suffer through poor connections or overloaded POPs. If you’ve been burned by “next-gen” solutions that still feel like 2008, it might be time for something new.

OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) and business VPN solution that gives organizations full control over their own secure network. It's software organizations deploy directly into their own environment — on-premises hardware or their own cloud account on AWS, Azure, Google Cloud, or others — with tunnel traffic flowing directly between users and the server. With Access Server Link, teams can go from zero to a fully configured deployment in minutes: point-and-click setup across AWS, Azure, and GCP, automatic SSL certificate provisioning and renewal, and a web-based admin portal for managing users, certificates, and access — no SSH or manual DNS work required. Access is granted per application and per identity using domain names rather than broad network-level access, so users only reach what they're explicitly permitted to, and lateral movement is structurally blocked.

The way we work has changed. People now work from anywhere, not just from an office. Applications are based in the cloud, not just on-premise. And the company network perimeter is now spread across the internet. Using a traditional, network-centric VPN for remote access is not only outdated and difficult to maintain, but exposes businesses to security breaches. VPN infrastructure is costly and time-consuming to procure, deploy, and maintain. Inability to secure access at the app level means hacks can expose whole networks. Twingate enables organizations to rapidly implement a modern Zero Trust network that is more secure and maintainable than VPNs. Delivered as a cloud-based service, Twingate empowers IT teams to easily configure a software-defined perimeter without changing infrastructure, and centrally manage user access to internal apps, whether they are on-prem or in the cloud.
