Room For Improvement

Microsoft Defender Vulnerability Management needs enhanced accuracy, better integration, user-friendliness, cost-effectiveness, and improved platform management and reporting.
Proofpoint Email Protection struggles with setup complexity, feature enhancements, pricing issues, and requires improved support and interface design.

Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.

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.
