| Best for | AWS-committed teams that need segmented networks, private subnets, and hybrid connectivity; overkill for single simple servers | Infrastructure teams building standards-compliant IPsec gateways, site-to-site tunnels, or certificate/EAP-based remote access on Linux, BSD, or embedded hardware, who are comfortable operating open-source security software. |

AWS VPC
Pros
- + Free core service — no charge for VPCs, subnets, route tables, or security groups
- + Deepest virtual networking feature set available: peering, Transit Gateway, PrivateLink, flow logs, traffic mirroring
- + 39 Regions / 120+ Availability Zones with real multi-AZ fault isolation
- + Native IPv6 (dual-stack and IPv6-only) at no extra charge
- + Free baseline DDoS protection via AWS Shield Standard
Cons
- - NAT gateways add up fast: $0.045/hour per AZ plus $0.045/GB processed
- - No SLA attached to VPC itself
- - Architecture-level cost opacity — public IPv4, cross-AZ and egress charges interact
- - Steep learning curve and AWS lock-in once topology grows
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
