A3Sec CTEM vs Astelia AI-Native Exposure Management Platform: 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.

Astelia AI-Native Exposure Management Platform

Mid-market and enterprise teams drowning in disconnected vulnerability and asset data will get immediate value from Astelia AI-Native Exposure Management Platform because it actually models network reachability instead of just listing CVEs in isolation. The platform's attack path visualization and agentic AI-driven correlation across network topology, runtime context, and compensating controls maps directly to NIST ID.RA and ID.AM, giving you the asset risk picture your current tools pretend to deliver. Skip this if your organization lacks network visibility as a baseline; garbage topology data means garbage remediation guidance, and Astelia won't fix that upstream problem.
