Cohesive VNS3 Cloud Firewall vs Sphyrna NGXS AGW-200: Side-by-Side Comparison (2026)

Cohesive VNS3 Cloud Firewall

Mid-market teams managing multi-cloud infrastructure will get the most from Cohesive VNS3 Cloud Firewall because it actually handles network segmentation and transit routing without forcing you into a single vendor's ecosystem. The containerized plugin architecture and multi-cloud deployment support mean you're not rearchitecting when you move workloads between AWS, Azure, or on-premises; NIST PR.AA coverage confirms granular access control across those boundaries. Skip this if you need a managed service with minimal operational overhead; VNS3 demands hands-on network configuration and assumes your team understands IPsec and policy enforcement.

Sphyrna NGXS AGW-200

Enterprise and mid-market security teams protecting classified or highly sensitive networks will value the NGXS AGW-200 for its unidirectional enforcement; once data crosses this gateway, it cannot flow backward, which eliminates an entire category of exfiltration risk that standard firewalls merely monitor. Common Criteria EAL 4+ certification and ITSG-33 compliance confirm the hardware-based diode architecture, and the dual audit ports let you maintain separate forensic trails on each network segment. Skip this if you need east-west microsegmentation or dynamic policy updates; this tool solves a narrower problem, which is exactly why it solves it well.
