Sphyrna NGXS UGW-100 Unidirectional Gateway is a commercial next-generation firewalls tool by Sphyrna Security. Endian UTM is a commercial next-generation firewalls tool by Endian. Compare features, ratings, integrations, and community reviews side by side to find the best next-generation firewalls fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Mid-market and SMB teams needing perimeter security with actual visibility into encrypted traffic will find Endian UTM does the job without overengineering. It covers the basics well: IPS, web filtering, email filtering, and VPN at a price point that doesn't require justifying to finance, plus hardware and virtual deployment options mean you're not locked into one model. Skip this if you're an enterprise expecting 24/7 vendor support or need deep integration with your existing SIEM; Endian's a straightforward gateway that stops threats at the edge, not a platform that talks to everything else in your stack.
