6WIND Virtual Service Router (VSR) vs Secturion DarkLink: Side-by-Side Comparison (2026)

Secturion DarkLink

Enterprise and mid-market security teams moving sensitive data across multi-site networks need DarkLink if they're bound by DoD compliance requirements or operate in environments where Ethernet-layer encryption is a hard architectural constraint. The tool delivers 256-bit AES-GCM encryption at up to 400 Gbps with native support for DoD EDE specification compliance, and its MESH technology eliminates the need to rebuild site-to-site connectivity around commercial VPN stacks. Skip this if your organization runs cloud-first infrastructure or lacks the on-premises network footprint to justify dedicated encryption appliances; DarkLink is purpose-built for traditional data center and government contractor environments, not hybrid cloud.
