The Continuous Threat Exposure Management or CTEM is a five-stage approach to continuously expose an organization's networks, systems, and assets to simulated attacks to identify vulnerabilities and weaknesses. This allows shifts from point-in-time vulnerability assessments to a repeatable security posture remediation and validation program.

It also helps prioritize potential risk mitigation strategies and continually refine the security posture improvement plan. This is done by regularly exposing an organization's assets to simulated attacks to identify and fix vulnerabilities and control gaps before malicious actors can exploit them.

CTEM is implemented through a combination of automated tools and manual testing. This includes red teaming, penetration testing, vulnerability scanning, and other activities. It feeds into key security-related functions and governance, risk, and compliance mandates to enhance and enrich them and support a more advanced security posture.

Five Core Stages of a CTEM Program

The five stages of a CTEM program with what should be done in each step is listed below:

  • Scoping: Understand and identify the most important assets and potential impacts to the business.
  • Discovery: Uncover assets and their risk profiles, including misconfiguration of assets, security controls, and other weaknesses.
  • Prioritization: Identify and address the threats most likely to be exploited against an organization.
  • Validation: Validate how potential attackers can exploit an identified exposure and the potential response of monitoring and control systems.
  • Mobilization: Operationalize findings by reducing obstacles to approval, implementation processes, and mitigation deployments.

By focusing on these five pillars, organizations can build a CTEM program that effectively safeguards their critical assets and data.
