Compare features, ratings, integrations, and community reviews side by side to find the best operational technology asset discovery fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Maritime operators managing mixed legacy and modern vessel fleets will find CyberOwl Medulla essential for IMO 2021 compliance without ripping out existing systems; the platform monitors operational technology assets across distributed vessels while surfacing cyber risk in terms board members actually care about. Deployment is cloud-based with no requirement to replace onboard systems, and the vendor's continuous monitoring focus (NIST DE.CM) means anomalies get flagged before they become incidents. This tool assumes you're already managing cybersecurity as a fleet-wide problem rather than ship-by-ship; buyers expecting traditional IT network visibility or integration with enterprise SOCs will find Medulla too specialized.
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.
