Sphyrna NGXS UGW-100 Unidirectional Gateway is a commercial next-generation firewalls tool by Sphyrna Security. Zecurion Secure Web Gateway is a commercial next-generation firewalls tool by Zecurion. Compare features, ratings, integrations, and community reviews side by side to find the best next-generation firewalls fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
