CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise maritime operators need RAD because it discovers OT assets across hybrid IT/OT networks without requiring onboard hardware or disrupting vessel systems, a constraint that kills most traditional discovery tools in this domain. The ClassNK certification and passive scanning with 60-minute active phases prove the vendor understands maritime ops; E26 compliance support closes a real gap in the category. Skip this if your fleet runs purely air-gapped networks or if you need NIST ID.RC recovery capabilities built in; RAD prioritizes asset visibility and continuous monitoring over incident response orchestration.
