Senior Cybersecurity Specialist at a retailer with 10,001+ employees
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.

Has improved email security through advanced filtration and timely threat detection
I work with Trend Micro Apex One. I have used the Deep Discovery's Sandbox analysis feature, and we utilize another appliance known as Deep Discovery Analyzer, abbreviated as DDA. This tool makes analysis for URLs and attachments contained in inbound emails, so whenever we receive an email with a URL or attachment, it will be analyzed by Trend Micro Deep Discovery Analyzer. In evaluating Deep Discovery's real-time visibility on network traffic, it is important to note that we applied our Deep Discovery Analyzer for Trend Micro to conduct sandboxing specifically for email channels only, and we do not utilize it for network channels. For network channel sandboxing, we use a solution called FortiAnalyzer, which belongs to another team called network security. I assess Deep Discovery's effectiveness in identifying sophisticated attack patterns by looking at how it handles high traffic loads, and how effectively it can use its instances and images to analyze numerous URLs and attachments simultaneously. Additionally, I evaluate its ability to maintain round-robin or load balancing across different analyses without leaving samples queued for analysis. The performance is critical when the product updates for signatures are up-to-date, as this aids in the detection and classification of URLs and attachments without delay in the analysis process. On a scale of one to ten, I rate Trend Micro Deep Discovery a nine.
