Sphyrna NGXS UGW-100 Unidirectional Gateway vs Monitorapp AISVA: 2026 Comparison

Sphyrna NGXS UGW-100 Unidirectional Gateway

Enterprise and mid-market security teams protecting high-value unidirectional data flows from compromised networks will find the NGXS UGW-100 uniquely suited to this job; the optical-electrical-optical architecture is physics-based assurance, not policy-based, and the EAL 4+ certification plus NSA approval matters when you're defending against nation-state adversaries. The two-person approval requirement for configuration changes enforces accountability in environments where insider risk is a live threat. Skip this if you need bidirectional communication or sub-10Gbps performance; the tool is purpose-built for one-way transfer and doesn't compromise on that constraint.

Monitorapp AISVA

Mid-market and enterprise security teams encrypting 40–60% of network traffic will find Monitorapp AISVA worth the deployment effort because it actually decrypts SSL/TLS at scale without breaking failover or certificate management. The automated certificate lifecycle and transparent proxy integration mean your ops team isn't manually patching expiration dates or rebuilding policies after outages. Skip this if your organization runs primarily cloud-native or SaaS workloads where decryption happens upstream; AISVA's value is on-premises networks with hybrid traffic inspection needs.
