CTEM isn’t failing. It’s not being operationalized

Continuous Threat Exposure Management (CTEM) programs often fail not because organizations don't understand the Gartner framework's five phases, but because they can't operationalize it. The real challenge lies in execution: unclear ownership, fragmented accountability across security and infrastructure teams, inconsistent validation, and no reliable way to measure whether exposure is actually decreasing. Success requires shifting focus from framework phases to operational questions — who owns the process, how findings move between teams, and how remediation outcomes are verified. The post promotes a webinar and a playbook from Horizon3.ai on building a repeatable CTEM operating model.
