Overview

Move over ASM, 'CTEM is the way'. If you're responsible for managing your organization's external attack surface, chances are you're already doing parts of Continuous Threat Exposure Management (CTEM), you just haven't been calling it that. In this webinar, we'll go beyond the buzzwords and explain what CTEM really is and how it aligns with our definition of 'true ASM' required to keep pace with a constantly evolving threat landscape.

To coincide with the release of Searchlight Cyber's new ebook, ASM in the age of CTEM, we've invited Searchlight's Head of Threat Intelligence, Luke Donovan, and Customer Success Manager Joe Honey, to cover:

  • Why ASM has become too narrow to address modern threats
  • Real-world examples of CTEM in action and how it improves security outcomes
  • Practical steps to help your team move from asset discovery to exposure reduction

For years, Attack Surface Management (ASM) has been positioned as the answer to managing external risk. But in recent times, the term has become misapplied, often reduced to asset discovery tools with limited impact on actual risk reduction. CTEM restores the full picture and more effectively represents how mature cybersecurity teams manage external risks as part of a continuous cycle of discovery, enrichment, validation, and mitigation.
