Features, integrations, deployment and the company behind each one, side by side.

## Our take

What our shortlists say about the one we picked.

### [Sophos EDR](https://cybersectools.com/tools/sophos-intercept-x)

Best for: Mid-sized teams wanting one cloud console

It earns its place because detection and response come in the same agent as prevention, so teams that already run Sophos Endpoint can turn on EDR from the Sophos console without a new agent. That suits teams that want one console for endpoints and other Sophos products. Only one integration is listed, so check how it will feed your SIEM if you run one.
