Exposed: The Comedy of EASM Blind Spots and Cybersecurity Blunders
External attack surface management (EASM) is crucial for protecting against cyber threats, but relying solely on Microsoft Defender might not cut it. Many security-mature organizations still face breaches due to EASM blind spots, like unmanaged subdomains or legacy servers. Boost your defenses with continuous scanning and an additional EASM layer beyond Defender.

Hot Take:
So, you’ve got a fortress surrounded by a moat, but you forgot to lock the back door? Welcome to the world of External Attack Surface Management (EASM), where the real challenge isn’t just about having a shield—it’s about making sure you’ve got all the holes plugged. Spoiler alert: Microsoft Defender alone won’t cut it. It’s like bringing a knife to a cyber gunfight—great for peeling oranges, not so much for warding off cyber ninjas.
Key Points:
- Attackers target internet-facing assets first, looking for vulnerabilities.
- Microsoft Defender is widely used but might not be sufficient alone.
- Common EASM blind spots include shadow IT, old infrastructure, and third-party risks.
- AI helps both attackers and defenders in EASM, making it a double-edged sword.
- Continuous scanning and multi-layered EASM strategies enhance security.
