\u201cWe already manage our vulnerabilities; we perform regular security scans.\u201d<\/p>\n\n\n\n

If you\u2019re a CIO or CISO, you may have said this before. And it\u2019s a valid point: your tools are likely in place, your analysis cycles are scheduled, and your dashboards are filling up. On the surface, everything seems under control.<\/p>\n\n\n\n

The problem is that between scans, your attack surface continues to evolve. And your assets, once considered secure, may no longer be so.<\/p>\n\n\n\n

The challenge is therefore no longer just to detect your vulnerabilities at regular intervals, but to manage your exposure in real time<\/strong>, based on threats, your context, and your actual remediation capabilities.<\/p>\n\n\n\n

This is exactly what CTEM (Continuous Threat Exposure Management) <\/strong>promises: moving from a periodic control approach to continuous, structured risk management<\/strong>.<\/p>\n\n\n\n

In this article, we\u2019ll break down this now-essential approach, understand how it redefines vulnerability management, and explain how Cyberwatch enables you to integrate it into your practices.<\/p>\n\n\n\n

<\/a>CTEM: A New Approach to the Limitations of Traditional Vulnerability Management<\/strong><\/h2>\n\n\n\n

For years, vulnerability management (VM) and information system security relied on periodic audits: a monthly scan, a quarterly penetration test, an annual compliance audit.<\/p>\n\n\n\n

But this approach is no longer in step with the reality of modern information systems. And this is for several reasons:<\/p>\n\n\n\n

<\/a>1) Increasingly dynamic and ephemeral infrastructures<\/strong><\/h3>\n\n\n\n

The traditional vulnerability management model is based on a simple principle: taking a snapshot of the information system\u2019s security status at a given moment<\/strong>, analyzing the results, and then fixing the identified issues.<\/p>\n\n\n\n

But here\u2019s the thing: in the age of the cloud and continuous deployments, that snapshot becomes outdated the moment it\u2019s taken.<\/p>\n\n\n\n

Imagine a monthly scan cycle that runs on the 1st of the month. On the 3rd, your DevOps team deploys a microservice with a vulnerable dependency. On the 7th, a critical CVE is published for a component present in 30% of your infrastructure. On the 15th, an intern launches an EC2 instance to test a POC and forgets to deactivate it.<\/p>\n\n\n\n

Your next scan will uncover these issues 2 to 4 weeks later, at best.<\/p>\n\n\n\n

This scenario is not hypothetical. In modern architectures, with hybrid multi-cloud environments, thousands of microservices, Kubernetes-orchestrated containers, serverless functions, and publicly exposed APIs, your attack surface is effectively multiplied, and changes to your infrastructure are constant<\/strong>.<\/p>\n\n\n\n

The consequence is immediate: the asset inventory on which your analysis relies quickly becomes obsolete<\/strong>, and some assets slip through the cracks.<\/p>\n\n\n\n

<\/a>2) An exploding volume of vulnerabilities<\/strong><\/h3>\n\n\n\n

Beyond these blind spots in asset monitoring, the volume of vulnerabilities to address is increasing at an unprecedented rate<\/strong>.<\/p>\n\n\n\n

According to figures from FIRST<\/a> (Forum of Incident Response and Security Teams), nearly 50,000 CVEs were recorded in 2025. This represents an increase of approximately 21% year-over-year, following a rise already estimated at +39% between 2023 and 2024.<\/p>\n\n\n\n

Added to this avalanche of vulnerabilities is a shortening of exploitation timelines: attackers are now industrializing the exploitation of critical flaws, <\/strong>and for the most high-profile vulnerabilities (such as Log4Shell a few years ago), the time between disclosure and the first attacks sometimes drops to less than 24 hours.<\/p>\n\n\n\n

The result: the remediation window is shrinking drastically, further widening the gap with periodic analysis cycles.<\/p>\n\n\n\n

<\/a>3) <\/strong>Prioritization that remains too disconnected from actual risk<\/strong><\/h3>\n\n\n\n

In this context, you can no longer address everything: you need to know what to fix first, and by when.<\/p>\n\n\n\n

However, in traditional approaches, prioritization still relies heavily on generic technical scores (CVSS), without taking into account:<\/p>\n\n\n\n
