CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams drowning in unknown assets and exposure backlogs will see immediate value in A3Sec CTEM's continuous discovery paired with automated attack simulation; it forces prioritization by actual exploitability rather than CVE noise. The vendor's coverage across NIST ID.AM, ID.RA, and DE.CM reflects genuine strength in asset mapping and risk contextualization where most exposure tools leak. Skip this if your organization prioritizes incident response over exposure prevention or lacks the resources to act on continuous remediation workflows; A3Sec assumes you can operationalize findings at scale.
Mid-market and enterprise teams responsible for OT and IoT security should pick Claroty Exposure Management because it actually discovers and maps cyber-physical assets that traditional IT tools ignore, using passive monitoring and safe active queries that won't destabilize operational networks. The platform covers ID.AM and ID.RA across NIST CSF 2.0, meaning it handles both asset visibility and risk prioritization for environments where downtime costs more than the breach itself. Skip this if your environment is primarily IT-focused or if you need deep forensics and response capabilities; Claroty prioritizes discovery and attribution over post-incident investigation.
