OneLayer Bridge vs Zscaler IoT and OT Security: Side-by-Side Comparison (2026)

OneLayer Bridge

Mid-market and enterprise operators of private 5G networks or cellular IoT deployments need OneLayer Bridge because it enforces Zero Trust segmentation at the cellular core layer, not just the edge, where most network segmentation tools stop. The platform covers the full asset lifecycle from device fingerprinting through persistent tracking and policy enforcement via PCF/PCRF integration, addressing NIST ID.AM and PR.AA gaps that generic network segmentation leaves open in cellular environments. Skip this if your cellular infrastructure is brownfield with minimal new deployments; OneLayer's value concentrates in organizations building or substantially upgrading private networks where device classification can happen at enrollment rather than retrofitted onto existing traffic patterns.

Zscaler IoT and OT Security

Enterprise security teams managing sprawling IoT and OT networks will see immediate value in Zscaler IoT and OT Security's agentless device discovery and segmentation, which bypasses the usual firmware compatibility headaches that plague traditional firewall-based approaches. The platform's zero trust segmentation without agents covers both ID.AM asset management and PR.AA access control, two areas where most OT shops have critical blind spots. Skip this if your environment is heavily air-gapped or your vendors won't tolerate cloud-based visibility; the cloud deployment model is a feature for most, a non-starter for some.
