Kamerka is a free operational technology asset discovery tool. Armis Centrix™ for Medical Device Security is a commercial operational technology asset discovery tool by Armis. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology asset discovery 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:
Industrial security teams without existing OT asset visibility should start with Kamerka before buying expensive discovery platforms. It's free, runs on Shodan's public internet scan data, and surfaces exposed industrial devices in minutes; 788 GitHub stars reflect active use by practitioners who actually hunt ICS/IoT risks. The major caveat: Kamerka only sees what's internet-facing, so networks properly segmented from external access won't benefit, and you'll still need manual validation and network-specific tools to understand what lives on your actual operational floors.
Armis Centrix™ for Medical Device Security
Mid-market and enterprise healthcare security teams drowning in unmanaged medical device sprawl need Armis Centrix because it actually finds what you don't know is there, then tells you which devices actually matter for patient safety. Passive discovery across unagented devices combined with patient-centric risk prioritization covers NIST ID.AM and DE.CM without requiring network cooperation or device access, which is critical when you're managing legacy ventilators and infusion pumps alongside IT assets. Skip this if your organization wants one platform handling both OT and IT vulnerabilities end-to-end; Centrix prioritizes visibility and continuous monitoring over remediation workflow integration, so you'll still need separate patch management for the devices it surfaces.
