Exposure management: See yourself like an attacker
Oct 8th, 2025 by Jesper Kråkhede
For years, vulnerability management has meant a long list. Thousands of missing patches and misconfigurations, sorted by severity score. The teams work through it, the list never ends, and the attackers still get in through something that was ranked medium.
Exposure management is a different way of looking at it. Instead of a list, it looks at your environment the way an attacker does: as a graph of identities, devices, applications, cloud resources and the connections between them. The question isn´t ‘what is vulnerable?’, but ‘how can an attacker get from the internet to the things that matter, and which step is easiest to break?’
That is what attack paths show. A vulnerable server exposed to the internet, which has a cached credential of an admin, who has rights in a cloud subscription, where the customer database lives. Each step on its own might look medium. Together they are a highway. Fix one link, the chokepoint, and many paths disappear at once.
But none of this works unless you have defined your critical assets. Exposure management needs to know what you are protecting: the domain controllers, the identity platform, the admins, the databases with customer data, the systems that run production, the backup. If everything is critical, nothing is. Defining critical assets is a business decision as much as a technical one, and it is the single most important step. Microsoft Security Exposure Management lets you classify them, and the attack paths and recommendations are prioritised around them.
Then the work changes. Instead of patching for the sake of the list, you remove the paths to what matters most. Fewer actions, more effect.
Measure exposure, not effort. Report how many attack paths lead to your critical assets, and how that number goes down.
Stop counting vulnerabilities. Start counting the ways in.
