## Our take

What our shortlists say about the one we picked.

### [Bitsight External Attack Surface Management](https://cybersectools.com/tools/bitsight-external-attack-surface-management)

Best for: Teams reporting cyber risk to boards and insurers

It earns a place because Bitsight IQ ties each discovered asset to the entity that owns it, and cloud IP addresses sync from AWS, Azure and Google Cloud several times a day. That suits a company with many subsidiaries or suppliers to map. Ask how attribution gets checked, since an asset tied to the wrong entity sends work to the wrong owner.
