Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Dispersive for Cyber-Physical & OT/IoT Security
Mid-market and enterprise operations teams defending OT/IoT networks should choose Dispersive for Cyber-Physical & OT/IoT Security because it actually works with legacy equipment instead of demanding rip-and-replace, and does this through network obfuscation rather than trying to bolt authentication onto devices that were never designed for it. The SOC 2 Type II SaaS option and software-defined overlay deployment mean you can start without overhauling your existing stack. Fair warning: this tool prioritizes access control and resilience over detection and response, so pair it with a separate monitoring layer if your SOC expects real-time anomaly hunting on OT traffic.
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.
