Blue Ridge Networks LinkGuard vs Goldilock TruAirgap™: Side-by-Side Comparison (2026)

Blue Ridge Networks LinkGuard

Mid-market and enterprise security teams defending distributed workforces should consider LinkGuard for its network micro-segmentation paired with cellular-aware remote access, a combination most NAC vendors skip. The vendor covers all four NIST CSF 2.0 categories from access control through continuous monitoring, and the quantum-resilience encryption layer adds genuine future-proofing against data harvesting attacks. Skip this if your priority is visibility into east-west traffic anomalies; LinkGuard emphasizes enforcement and asset obfuscation over the detection analytics that catch lateral movement in real time.

Goldilock TruAirgap™

Enterprise and mid-market teams protecting critical infrastructure or handling high-stakes third-party access will value Goldilock TruAirgap™ for its physical, out-of-band isolation that survives network compromise. The 12-port Layer 1 switching with non-IP management and SMS-based authentication means an attacker controlling your production network cannot flip a port without a separate, parallel command channel. The tool strengthens PR.IR capabilities by design; it's weak on RS.MI, so pair it with incident response automation rather than expecting TruAirgap™ to contain lateral movement on its own. Skip this if your threats are primarily application-layer or you lack dedicated infrastructure staff to manage per-port scheduling.
