Enclave Networks
Pros
- + Eliminate VPN bottlenecks—direct peer-to-peer encryption removes centralized gateways
- + Reduce attack surface—zero trust model means no implicit trust, only cryptographic verification
- + Deploy faster—WireGuard-based setup requires minimal firewall or network reconfiguration
- + Scale efficiently—mesh topology handles growth without performance degradation
Cons
- - Smaller ecosystem compared to established VPN/SD-WAN vendors
- - Requires identity provider integration for policy enforcement—not plug-and-play for basic use cases
- - Learning curve steeper than traditional VPN for teams unfamiliar with zero-trust models
Nebula
Pros
- + Open source by Slack engineers
- + Scales to hundreds of thousands of nodes
- + Firewall rules built into protocol
Cons
- - Requires manual configuration
