How Adversaries Exploit the Blind Spots in Your EASM Strategy

Internet-facing assets like domains, servers, or networked device endpoints are where attackers look first, probing their target’s infrastructure to determine if there is a viable way in. External attack surface management (EASM) is how security teams stay ahead of such vulnerabilities, which is why it’s become so critical for shoring up defences.

However, many security teams only rely on Microsoft Defender for EASM, which might not be enough. We regularly see some of the most security-mature organisations suffer breaches, indicating that there are some gaps in how EASM is being implemented across industries.

How EASM Blind Spots Become Entry Points

With powerful, widely available scanners like Shodan, Censys, or custom-built scanners, attackers are always probing the internet to identify any exposed assets. Something as simple as an open port or misconfigured server can signal to them that a service is active and potentially exploitable.
