## Our take

What our shortlists say about the one we picked.

### [Searchlight Exposure](https://cybersectools.com/tools/assetnote-attack-surface-management-tool)

Best for: Teams wanting hourly scans and zero-day warnings

It earns a place on speed, because hourly scans and its own vulnerability research mean you hear about a new exposure or zero-day sooner. That suits a team whose external footprint changes every day. Ask how its proof-of-concept exploits are shared and used, because they are strong evidence but need careful handling.
