Best VPN & Zero Trust Networks Tools
Secure remote access solutions including VPN servers and zero-trust networking tools.
Open-source VPN and zero-trust networking tools provide mechanisms for secure remote access, device-to-device connectivity, and policy-driven network segmentation. Projects such as Headscale, NetBird, Teleport, and OpenZiti are commonly used to replace or augment traditional VPNs with identity-centric controls. These solutions can be self-hosted or integrated with SaaS offerings, allowing organizations to tailor encryption, authentication, and routing to their specific security posture while leveraging community support and transparent codebases.

What to evaluate
01Security model
Assess the strength of encryption, authentication methods (e.g., mutual TLS, OAuth), and how the solution enforces least-privilege access.
02Scalability and performance
Consider the ability to handle large numbers of concurrent users, mesh topology efficiency, and impact on latency.
03Deployment complexity
Evaluate required infrastructure, configuration effort, and availability of automation tools or containers.
04Community activity and support
Review repository activity, issue response time, documentation quality, and availability of commercial support.
05Integration capabilities
Check compatibility with identity providers, orchestration platforms, and existing network monitoring tools.

Zscaler is a cloud security platform offering Secure Web Gateway and Zero Trust Network Access solutions. Instead of routing traffic through corporate networks, users connect to Zscaler's cloud, which inspects web traffic for threats and enforces security policies (blocking malicious sites, filtering content). For private applications, Zscaler brokers a secure connection between the user and the app based on identity and context, eliminating the need for VPNs while keeping internal services hidden from the internet. By doing so, Zscaler provides fast, secure access for remote and mobile users and simplifies network security in a cloud-first world.
Typical usage patterns
01Remote workforce access
Provide employees working off-site with encrypted tunnels that respect identity-based policies rather than static IP ranges.
02Inter-datacenter connectivity
Create a mesh network linking multiple data centers or cloud regions without exposing traffic to the public internet.
03Secure IoT device communication
Enroll devices into a zero-trust fabric that validates posture and identity before allowing data exchange.
04Application-level access control
Enforce granular permissions for specific services or APIs, reducing the attack surface compared to broad network access.
05Hybrid cloud networking
Bridge on-premise resources with public cloud workloads using a unified, policy-driven overlay.
Frequent questions
What is the main difference between a traditional VPN and a zero-trust network?
Traditional VPNs grant network access based on location or device, while zero-trust networks require continuous identity verification and enforce least-privilege policies for each connection.
Which open-source projects are most widely adopted for zero-trust networking?
Headscale, NetBird, Teleport, OpenZiti, and Netmaker are among the most starred and actively maintained projects in the open-source zero-trust space.
How do these tools handle authentication and encryption?
They typically use mutual TLS for encrypted tunnels and integrate with external identity providers (OAuth, SAML, LDAP) to authenticate users and devices.
Can the solutions be self-hosted in on-premise environments?
Yes, all listed open-source projects can be deployed on-premise, in private clouds, or in container orchestration platforms like Kubernetes.
What performance considerations should be evaluated when deploying a mesh VPN?
Key factors include node count, bandwidth overhead from encryption, latency introduced by hop routing, and the efficiency of the underlying peer-discovery mechanism.
How do licensing and community support affect the choice of an open-source solution?
Most projects use permissive licenses (e.g., Apache 2.0, MIT) and rely on community contributions; organizations should assess activity levels, issue response times, and availability of commercial support if needed.
