## Our take

What our shortlists say about the one we picked.

### [Sophos MDR](https://cybersectools.com/tools/sophos-mdr)

Best for: Teams without a SOC that run mixed security products

Sophos MDR makes the list because it works on top of the products you already own, and incident response comes with no hourly caps. That suits companies of any size without their own SOC, especially if you would rather not replace your endpoint product. Ask which response mode you are buying, because the option you pick decides how much the analysts do on their own.
