Everything you need to know to maximise your cyber defence with CTEM and ASV
You are under constant threat. In an increasingly digital world, your data can be compromised any day, without notice.
But here’s the unpopular opinion: you can  take steps to reduce the risk and make your world safer.
This is especially true and critical for organisations who need to retain their customers’ personal and sensitive records in order to serve them better. In doing so, organisations face a multitude of threats that require robust and proactive measures.
Two must-have approaches for today’s cyber defence are Continuous Threat Exposure Management (CTEM) and Automated Security Validation.
Here’s everything you need to know about these concepts, their differences, and their overlaps and why they’re essential for maintaining a strong security posture and mitigating cyber threats effectively for your organisation.
Let’s dive in.Â
What is Continuous Threat Exposure Management (CTEM)?
CTEM a proactive and continuous cyber security strategy introduced by Gartner in 2022, designed to shift the focus from traditional, reactive vulnerability management to a more dynamic and continuous approach.
Think of it as your personal continuous feedback loop that identifies, assesses, and mitigates risks to your organisation’s networks, systems, and assets.
How does CTEM work?
By leveraging attack simulations and continuous monitoring to identify vulnerabilities and enhance security resilience. CTEM integrates various tools and techniques, such as penetration testing, attack surface management, and threat intelligence, to provide a proactive defence against potential threats.
What is Automated Security Validation (ASV)?
Automated Security Validation, on the other hand, focuses on the automated testing and validation of your security controls. Using technologies like automated penetration testing and breach and attack simulation, it not only continuously tests but also validates your organisation’s security posture to ensure they are effective against potential threats.
How does ASV work?
By leveraging automation to conduct ongoing assessments, providing real-time insights into security gaps and vulnerabilities through:
- Continuous testing: Regularly performing automated penetration tests to identify vulnerabilities.
- Real-world simulation: Emulating adversary tactics to test the organisation’s defences.
- Validation: Ensuring that security controls are functioning as intended.
- Breach and Attack Simulation (BAS): Conducting automated breach and attack simulations to assess security controls.
- Continuous assessment: Providing ongoing validation of the organisation’s security measures.
- Threat emulation: Using the latest threat intelligence to simulate real-world attack scenarios.
CTEM vs ASV: A Quick Summary
- CTEM offers a holistic, programmatic approach to managing cyber risks, focusing on continuous monitoring, threat intelligence integration, and comprehensive security posture management.
- ASV provides targeted, automated validation of specific security controls, making it ideal for resource-constrained environments and organisations needing to meet specific compliance requirements.
Both approaches emphasise continuous monitoring, proactive threat management, and the integration of security measures with existing programs.

Overlapping areas of CTEM and ASV
While CTEM and ASV are vulnerability assessment and exposure management solutions, and have distinct approaches and goals, they also share several overlapping areas that enhance an organisation’s security posture.
These commonalities help integrate both methods into a cohesive cybersecurity strategy.
- Continuous monitoring:Â Both CTEM and ASV place a strong emphasis on continuous monitoring of your cyber environment like real-time threat detection, ongoing assessment and continuous security validation.Â
- Validation techniques: Validation is a critical component of both CTEM and ASV, using various technologies to ensure the effectiveness of security measures like automated testing, stimulated attacks and manual assessments.
- Proactive approach: Both CTEM and ASV adopt a proactive approach to cybersecurity, aiming to identify and mitigate vulnerabilities before they can be exploited like early detection, preemptive remediation and continuous improvement.
- Integration with existing security programs: CTEM and ASV can complement traditional vulnerability management and other security initiatives, enhancing overall security resilience like enhancing security programs, supporting business goals, and improving security posture.
In Summary
By leveraging the overlapping areas of CTEM and ASV, your organisation can develop a robust exposure management program that enhances your overall security resilience. This integrated approach ensures that your security team can proactively manage risks, validate security controls, and continuously improve your security posture in alignment with business goals.
