## Our take

What our shortlists say about the one we picked.

### [Proofpoint Core Email Protection](https://cybersectools.com/tools/proofpoint-threat-protection)

Best for: Large companies wanting deep email filtering

It earns a place because it goes past filtering into DLP, encryption, archiving and fraud defense from one vendor, which suits a large company that wants to run email security as one program. Archiving and supervision for SEC and FINRA rules matter if you work in financial services. Weigh which parts you really need, because the whole platform is a bigger commitment than a filter.
