## Our take

What our shortlists say about the one we picked.

### [Sophos Firewall](https://cybersectools.com/tools/sophos-firewall)

Best for: Small IT teams wanting firewalls and endpoints in one console

Sophos is here because the firewall, endpoints and MDR can act on the same threat together, which means fewer steps for a small IT team. It sells to all sizes but fits best where a few people run the whole network. The value depends on running Sophos endpoints too, so if you use another endpoint product, weigh it as a firewall alone.
