Features, pricing, ratings, and pros and cons, compared head to head.
Nozomi Networks Nozomi Smart Polling is a commercial ot asset discovery tool by Nozomi Networks. Sepio Cyber is a commercial cps protection tool by Sepio Cyber. Compare features, ratings, integrations, and community reviews side by side to find the best ot asset discovery fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
Mid-market and enterprise operations teams managing OT/IoT environments where passive discovery leaves blind spots will get the most from Nozomi Networks Nozomi Smart Polling; active polling finds non-communicating devices and firmware patch status that network traffic alone cannot surface. The tool integrates directly with Guardian's passive baseline, meaning you're adding surgical interrogation to existing visibility rather than bolting on another silo. Skip this if your OT footprint is small enough that passive discovery already covers your critical assets, or if you lack the network segmentation to safely execute active polling without production risk. Mid-market and enterprise operations teams struggling to inventory unmanaged devices on their network will find real value in Sepio Cyber's agentless discovery and rogue device detection, which catches shadow assets that traditional asset management tools routinely miss. The platform's strength in NIST ID.AM and PR.PS aligns directly with the hardest part of device hygiene: knowing what's actually connected before you can control it. Skip this if your priority is endpoint response or forensics; Sepio is purely about finding and inventorying what you didn't know you had.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
