Pritunl
Pros
- + Free Community tier with a single server and unlimited users — usable without registration or a credit card
- + Per-server pricing with unlimited users keeps licensing flat as teams grow
- + Real identity integration: SSO providers, LDAP/Active Directory/OAuth sources, TOTP and push second factors
- + Security engineering beyond the category norm: SELinux policies, TPM and Apple Secure Enclave device attestation, dynamic firewall
- + Both OpenVPN and WireGuard clients, plus WireGuard/IPsec site-to-site links and multi-cloud VPC peering
- + All source code public on GitHub since 2013 — auditable and customizable via the Python plugin system
Cons
- - SSO, failover clustering, and site-to-site links are gated behind the $70/month Enterprise tier
- - Self-hosting means you own patching, MongoDB operations, certificate rotation, and incident response
- - No vendor SLA or published support response guarantees in the documentation we reviewed
- - MongoDB becomes part of the VPN trust boundary and needs its own hardening
- - Scale claims (thousands of concurrent users) are vendor statements we could not verify independently
strongSwan
Pros
- + Complete IKEv2 (RFC 7296) implementation with IKEv1 legacy support, free under GPLv2
- + Deep authentication: X.509 attribute certificates, PKCS#11 smartcards, TPM 2.0, EAP/RADIUS
- + Multiplatform — Linux, FreeBSD, macOS, Windows (MinGW), and a native Android client
- + Two-node HA mode with state takeover, MOBIKE for roaming peers, full IPv6 support
- + Plugin architecture and distro packages make it embeddable and easy to deploy
Cons
- - Steep configuration learning curve — swanctl, IKE proposals, and IPsec policy are expert tooling
- - No vendor SLA; free community support, commercial support is optional and limited
- - Overkill for simple server-to-server encryption where WireGuard is easier and faster
- - Patching and PKI operations are entirely on you
- - No control plane, dashboard, or appliance — it is a component, not a product
