A3Sec CTEM is a commercial exposure management tool by A3Sec. Onit Security is a commercial exposure management tool by Onit Security. Compare features, ratings, integrations, and community reviews side by side to find the best exposure management 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:
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.
