Experience boosts operational efficiency while performance sees room for improvement
I don't have specific information on whether it was purchased on the AWS marketplace or somewhere else. I am working with Dynatrace Operator. I am also working with Algosec, Alluvio, CrowdStrike, Firemon, Gigamon Deep Observability Pipeline, and other solutions. I think it's a good tool, and I am satisfied with it. We have not stored cloud workloads with Gigamon Deep Observability Pipeline yet; we are still on-premises. The technical support takes about one to two hours to respond, which is acceptable. I am satisfied with the scalability of the product. The interface is good.

Has provided reliable threat detection and simplified policy management
I do not have experience with Microsoft Purview products, but I know some Proofpoint products. I apologize, I do not have experience with the Purview one, but I do know the Proofpoint products. I'm not sure about the features of the Purview one. Compared to other products, Proofpoint's real-time threat intelligence makes it less noisy. They collect and share threat information effectively, which benefits all customers. I have seen a lot of improvements in Proofpoint's reporting and analytics compared to earlier days. As a leader in the market, I find the pricing for Proofpoint Email Protection is a little high. Their licensing models vary, and even the premium model adequately supports awareness campaigning, so I find it acceptable. Normally, they sell their products through resellers, not directly through AWS Marketplace. For us, we are clients of Proofpoint. I rate Proofpoint Email Protection a nine out of ten.
