Which should you choose?

Choose CrowdStrike EASM if

  • it matters most to you that it fits the enterprise stack (8/10)
  • it matters most to you that it finds the unlisted estate (7/10)

Choose CrowdStrike EASM if your team already works in the Falcon console and wants external exposure next to endpoint and vulnerability data. Look elsewhere if you need proof of exploitability on external assets, attribution to subsidiaries or a published price.

Choose Microsoft Defender EASM if

  • it matters most to you that it fits the enterprise stack (8/10)
  • it matters most to you that it finds the unlisted estate (7/10)

Choose Microsoft Defender EASM if you are Azure-first and want an external inventory you can try today. Look elsewhere if you need proof, containment or a built-in fix loop.
