Twingate

Twingate replaces legacy corporate VPNs with a zero-trust network access (ZTNA) model. Instead of putting users on the network, it creates identity-aware, encrypted, peer-to-peer connections directly from a device to the specific resource it needs, whether that is an internal app, a database, a Kubernetes cluster, or an on-prem server, without exposing the rest of the network. Admins deploy Twingate in minutes with no changes to existing infrastructure or DNS, then manage least-privilege access policies from a central dashboard with support for device posture checks, SSO providers like Okta and Entra ID, and infrastructure-as-code via Terraform. It is aimed at distributed engineering and IT teams that want VPN-level access control without VPN-level latency or attack surface.

NordLayer

NordLayer is a business-focused network security platform built by Nord Security, distinct from the consumer NordVPN service. It gives organizations a cloud-native business VPN, Zero Trust Network Access, and site-to-site VPN to secure remote and hybrid teams without deploying traditional hardware. The platform adds threat prevention that blocks malicious sites, dark web monitoring for leaked credentials, and device posture checks, and NordLayer states it is ISO 27001, HIPAA, SOC 2, and PCI-DSS compliant. NordLayer says over 15,000 businesses use the platform and that deployment can take as little as 10 minutes rather than months.

NetBird

NetBird is an open-source zero trust networking platform that replaces traditional VPN gateways with a WireGuard-based peer-to-peer mesh network, letting devices connect directly to each other instead of routing through a central bottleneck. It enforces least-privilege network segmentation with granular policies and integrates with identity providers like Okta, Google, and Microsoft for SSO and MFA. It checks device security posture such as firewall status, antivirus, geolocation, and MDM/EDR before granting access, logs all configuration changes and connection events with real-time SIEM streaming, and can be deployed as a free managed cloud service or fully self-hosted under its BSD-3 open-source license.

Teleport

Teleport is a software solution that provides secure access to infrastructure, allowing users to easily manage and protect their resources. It offers a simple and secure way to access and manage infrastructure, eliminating the need for VPNs, SSH, and other complex security measures.

OpenVPN Access Server

OpenVPN Access Server provides a secure, centrally managed VPN that can be deployed on‑premise or in the cloud. It offers a web‑based admin console, LDAP integration, and client‑side software for all major platforms. The free tier allows up to two concurrent connections, while additional users are licensed per connection. It is widely used by small businesses, remote teams, and enterprises needing granular access control and easy scalability.
