What is the difference between HOPZERO Sphere of Trust vs Portnox Cloud?

**HOPZERO Sphere of Trust**: Network containment tool using TTL/hop limits to restrict data travel distance. built by HOPZERO. Core capabilities include TTL-based packet lifetime containment — restricts how far packets travel by setting and enforcing TTL values, Network geo-fencing — prevents data from leaving defined network regions or cloud zones, Application tethering — confines applications to only their approved network resources.. **Portnox Cloud**: Cloud-native unified access control platform with NAC, ZTNA, and RADIUS. built by Portnox. Core capabilities include Network Access Control (NAC), Zero Trust Network Access (ZTNA), Cloud RADIUS authentication.. Both serve the Network Access Control market but differ in approach, feature depth, and target audience.
