Amazon GuardDuty vs. Proofpoint Advanced Threat Protection

In a multi-account/multi-tenant environment, GuardDuty often alerts us to possible malicious traffic before it becomes an issue. The ability to automatically enable GuardDuty creates baseline security which is crucial when an account is first created. It also helps greatly in environments where other users are able to create resources as often GuardDuty alerts us to insecure resources we did not know about. It can however sometimes be a little overzealous with its assessments alerting on benign activity which then requires suppression rules.

It is great out of the box and uses AI and machine learning to identify threats with minimal input. It does need to be configured and tuned to meet the needs of the organisation. Industry specific software that sends or receives emails may be affected by this product.

Proofpoint offers a lot of products, but they are not particularly well integrated. They all look different, and there is no central location to access them all from, which is disappointing. However, I do know they have a big push for upgrading the UI and usability, so this should improve in the coming months I hope.

Even though the product is good, the support can be lacking at times. The support needs to know their product inside and out, but there are times in which we figure out things before their support does. I feel as if we should not be able to fix issues that their support cant fix, hence the main reason for support.
