Twingate is rated higher (4.0 vs 3.7). Modular open-source IPsec/IKE (IKEv2, RFC 7296) suite for site-to-site and remote-access VPNs, with X.509, smartcard/TPM, and EAP authentication. Runs on Linux, FreeBSD, macOS, Windows, and Android; GPLv2, free. Fast TLS-based tunnels with SSO integration — Twingate does not use WireGuard.

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
Twingate
Pros
- + Genuinely free Starter tier for up to 5 users — not a trial, with 50 Resources and 10 networks
- + Outbound-only connectors: no open inbound ports, no bastion hosts, no published IPs to scan
- + Policy depth: device posture, WebAuthn MFA, SCIM, just-in-time and usage-based access
- + Public component-level status page, documented relay redundancy, published incident write-ups
- + Terraform, Pulumi, Helm and Docker deployment paths — access managed as code
Cons
- - SaaS control plane holds your access policy — disqualifying for fully self-hosted mandates
- - Not an internet VPN; per-resource model requires disciplined resource inventory
- - Geoblocking, static IPs and privileged access are Enterprise-only; DNS filtering is an add-on
- - Per-seat pricing scales linearly and gets expensive with many contractors or seasonal staff
- - Contractual SLAs are custom/Enterprise-only; the 99.99% figure is a reliability claim, not an SLA
