On 2026-09-16, Horizon3.ai released two downloadable, vendor-produced evaluation resources aimed at security leaders and evaluation teams assessing Continuous Threat Exposure Management (CTEM) technologies. The first, a CISO's CTEM Evaluation Checklist, poses five questions covering proof of exploitability, demonstrated impact, remediation verification, and long-term reduction of exploitable exposure; it flags reliance on scanner findings, risk scores, closed tickets, and isolated test results as red flags and urges evidence gathered from the buyer's own environment. The second, a CTEM Technology Evaluation Scorecard, scores technologies on a 0-3 scale across the six-stage CTEM operating model — from discovering exposure through verifying risk removal — with weighted overall scoring and evidence levels ranging from none to proven in your environment. Both resources share the same core message: evaluations should be based on repeatable, demonstrated evidence of exploitability and verified remediation in the evaluator's environment rather than stated feature claims. No independent validation of these materials was provided in the reports; both are explicitly identified as Horizon3.ai marketing content.
