The Need for Continuous Threat Exposure Management (CTEM)

In an exclusive conversation with Global Leaders Insights, Btissam Laaouina, Regional Information Security Officer at Vantive, explains how Continuous Threat Exposure Management (CTEM) is transforming the way organizations approach cyber risk. Laaouina highlights the shift from traditional vulnerability management toward a more contextual approach that prioritizes real-world exposure and business impact rather than simply counting vulnerabilities. She discusses the key stages of building an effective CTEM strategy—from scoping critical assets and discovering exposures to validation and remediation—while emphasizing the importance of cross-team collaboration. Laaouina also explores the role of AI and automation in helping security teams analyze complex threat landscapes and respond faster to emerging risks, while stressing that human expertise remains essential in guiding cyber-risk decisions.

What is CTEM and why is it so important in today’s cyber risk environment?

Continuous Threat Exposure Management, or CTEM, is, in essence, a way for organizations to understand where they are actually exposed to cyber threats on a continuous basis.

Traditionally, organizations have focused on identifying vulnerabilities, whereas today’s problem is slightly different, as organizations face hundreds of vulnerabilities, of which only a small percentage are actually exposed and pose a threat to the organization’s business.

CTEM is essential as it helps organizations understand what is actually important, as it links threat exposure with business risk and helps organizations prioritize those vulnerabilities that are actually being exploited by the attacker, as the digital environment is continuously changing.

How does CTEM differ from traditional approaches to vulnerability management?

Traditional approaches to managing vulnerabilities are largely about scanning systems, identifying vulnerabilities, and prioritizing them based on the severity score, e.g., CVSS.

CTEM is a little different in the sense that, instead of looking at the severity of the vulnerability, it looks at the context. For example, is the system exposed to the internet? Is there an exploit available? Does it lead to a critical system?

So, it's a shift from the number of vulnerabilities to the actual exposure. In other words, CTEM is about prioritizing what actually represents risk to the organization

What are the key stages that are usually involved in the development of an effective CTEM strategy?

There are a number of key stages that are usually involved in the development of an effective CTEM strategy. These stages include:

First, organizations need to identify the scope, including their critical assets and business services. Next, organizations need to conduct exposure discovery, which involves the identification of the organization's potential weaknesses.

This is followed by prioritization, where organizations identify the exposures that are of the highest risk, depending on their exploitability and business impact.

Validation is also a critical step, where organizations need to ensure that the identified exposures are indeed exploitable, usually through simulations. Finally, organizations need to conduct remediation and mobilization, including ensuring that the right teams are mobilized to deal with the identified risks.

What are the major challenges that organizations face while implementing CTEM?

One of the major challenges that organizations face while implementing CTEM is the issue of visibility. For instance, organizations have always had difficulties in keeping track of their assets, especially if they have deployed the cloud.

Another major challenge that organizations face while implementing CTEM is the issue of information overload. For instance, the security teams have information overload, which is caused by the numerous alerts that they have to deal with. Therefore, if they have to deal with CTEM, they may end up with information overload.

Finally, another major challenge that organizations face while implementing CTEM is the issue of organization. For instance, CTEM involves the collaboration of several teams, including the security teams, the IT teams, the DevOps teams, and the business teams.

What advice would you give organizations starting their CTEM journey?

My main advice would be to start small and focus on what matters most. Instead of attempting to analyze the whole infrastructure, organizations should begin with their most critical assets or services.

It’s also important to consider CTEM in the context of the broader risk management strategy, so that the conversation around risk exposure is one of business impact, rather than purely technical results. The goal is not perfection from day one, but rather continuous improvement.

How does CTEM evolve with the advent of AI, automation, and emerging technologies?

AI and automation have an important role to play in the evolution of CTEM. AI and automation can aid security teams in analyzing vast amounts of data, identifying attack paths, and predicting the likelihood of vulnerabilities being exploited.

At the same time, automation can aid organizations in responding to attacks in a timely manner, reducing the time between detection and mitigation. Even with the aid of AI, human expertise cannot be avoided. Decisions still have to be made.
