Byos Secure Lobby is a commercial operational technology network segmentation tool by Byos. Zscaler IoT and OT Security is a commercial operational technology network segmentation tool by Zscaler. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology network segmentation 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:
Mid-market and enterprise security teams protecting operational technology networks from lateral movement will find Byos Secure Lobby's microsegmented SDN overlay harder to bypass than perimeter-only approaches. The combination of Layer 2 encryption, RSA-secured outbound connections with zero pre-tunnel internet exposure, and direct inter-microsegment routing means attackers cannot pivot between OT devices without explicit policy allowance. Skip this if your priority is threat detection and response rather than access prevention; Byos is deliberately positioned on the containment side of the NIST framework, with minimal visibility into what's happening inside the microsegments once policies are enforced.
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.
