A3Sec CTEM vs ResilientX Unified Exposure Management: Side-by-Side Comparison (2026)

A3Sec CTEM

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.

ResilientX Unified Exposure Management

SMB and mid-market teams without dedicated third-party risk programs should start here: ResilientX automates vendor security assessments and dark web monitoring in ways that let skeleton security staff actually track supply chain risk without hiring two more people. The platform covers all four relevant NIST CSF 2.0 areas,asset discovery through vendor monitoring,and the automated questionnaire workflows eliminate the spreadsheet back-and-forth that kills these programs at smaller organizations. Skip this if you're Enterprise with mature GRC tooling and vendor teams already running independent assessments; the automation value shrinks when you've got headcount to throw at manual processes.
