Featured Reviews

Siva_Prasad - PeerSpot reviewer
Principal Consultant at Infosys
Email defenses have reduced phishing incidents and protect sensitive data across our enterprise
As things are evolving and threats develop in unpredictable ways, Proofpoint must adopt AI solutions and agentic solutions more aggressively and provide them to customers as part of service offerings. Inbuilt AI solutions would add more value and make Proofpoint a more premium choice for customers. With the help of AI solutions, agentic AI, and generative AI capabilities, the product would be more efficient than it currently is. Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam. Proofpoint should focus more on this area with back-end agents or other tools. Proofpoint should decide which emails are genuine and which are spam so it is not a challenge for end users. When receiving an email, end users should not have to determine whether to respond or not. Proofpoint should not release such spam emails and should strictly block such spam and spoof emails based on connection IPs. Currently, false positives occur in the product, and while this occurs in every product, it is an area where Proofpoint can focus on improving and reducing false positives. One email is enough for an end user to be deceived and lose money, so addressing this area is critical.
Anastasia Wairimu - PeerSpot reviewer
Team Manager at Ford
Gateway filtering has protected our organization and provides complete email threat prevention
In my opinion, the best features Trellix Email Security offers include its use for malware analysis as well as the enterprise-wide email quarantine system. My experience with the malware analysis and quarantine features is that they are easy to manage and they have been very effective because we have been able to quarantine any suspicious emails or prevent any attempt before it affects our systems. It is also very user-friendly and has a simple interface. Policies and rules are easy to create and they work with very little downtime or operational impact. Email delivery issues are easy to investigate and troubleshoot. Trellix Email Security has positively impacted my organization as it is user-friendly and does a good job detecting malicious attachments in email, providing complete email protection against all users and working well to stop advanced threats. The price is relatively the same as other competitors.
