Sphyrna NGXS UGW-100 Unidirectional Gateway vs Olfeo On-Premise Secure Web Gateway: 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.

Olfeo On-Premise Secure Web Gateway

SMB and mid-market teams needing to inspect HTTPS traffic without a cloud dependency will find Olfeo On-Premise Secure Web Gateway's SSL/TLS decryption and local proxy filtering straightforward to deploy behind existing firewalls. The granular policy engine tied to Active Directory and time-based rules handles the common case of controlling web access by user role and shift, which most competitors either oversimplify or lock behind expensive modules. Skip this if your organization has already standardized on cloud-native security or needs behavioral detection beyond signature scanning; Olfeo prioritizes traffic filtering over anomaly hunting, and the 54-person vendor means slower feature velocity than larger competitors.
