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.
Omkar Korulkar - PeerSpot reviewer
Technology Analyst at a tech vendor with 10,001+ employees
Centralized visibility has improved SOC investigations and supports faster, more accurate incident response
I think ReliaQuest GreyMatter could be improved further in a few areas. First, I want to see more flexibility in dashboard customization so analysts can configure views based on their roles and investigation requirements. Second, improving alert correlation accuracy and reducing overall false positive rates would help analysts focus on genuine possible threats rather than spending time validating repetitive low-priority alerts or false positives. Third, more detailed investigation timelines, better reporting capabilities, and simpler investigation integration configuration would make the platform more effective. I suggest continuously improving automation workflows to reduce repetitive manual tasks while allowing analysts to maintain control over critical response actions. Overall, I think these enhancements can make the platform more user-friendly and improve the efficiency of SOC operations. One additional improvement would be enhancing the investigation experience by providing more detailed context directly within the alert. For example, having a clear incident timeline, related alerts, historical activity, and threat intelligence information available in one place would make investigations easier. I believe these improvements would make day-to-day SOC operations smoother and allow analysts to focus more on proactive threat hunting and other complex investigations.
