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.

Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Proofpoint Email Protection is a strong and reliable solution for defending against advanced email threats, especially phishing and targeted attacks."
"Proofpoint Email Protection has definitely impacted my organization positively."
"Proofpoint Email Protection is very effective because they are very proactive, always ahead of the attackers, and were already detecting new kinds of attacks before customers thought about them."
"Proofpoint Email Protection's initial installation is straightforward. It took us less than a day to complete the implementation."
"Out of these three, no other email gateway can be compared with Proofpoint Email Protection."
"Using Proofpoint Email Protection has significantly improved SOC analyst workloads for my customers by enhancing response times and adding value through built-in threat investigation tools."
"It's easy to use, even for those new to IT."
"Proofpoint Email Protection is the best solution from the perspective of email security."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
"ReliaQuest GreyMatter saves around 60% of time or resources."
 

Cons

"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"The false positives are an issue."
"I want Security Awareness Training in there as a package deal. A lot of companies are starting to value email security a little bit more and take it a little bit more seriously, and the great product that we link together with a lot of these sales is a training product called Security Awareness Training. It is an upsell that we do with Proofpoint, and it is definitely something that I recommend everybody with email security to look into. It would be great if Security Awareness Training is included with the email security."
"One major threat is QR code phishing, along with TOAD (Telephone-Oriented Attack Delivery). TOAD attacks don't include links, URLs, or attachments in emails. Instead, attackers try to trick you into calling them, often by offering something enticing like a 50% discount on football matches."
"The solution can be expensive."
"The initial setup is complex."
"Regarding improvements or enhancements in Proofpoint Email Protection, I find the platform somewhat chaotic. It has too many different sections that perform the same function, which is very confusing."
"Some of the old portal features of Proofpoint Email Protection are missing in the new portal, so some of the settings could be modernized."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The end customer is buying our solution, which can be for monthly or annual usage depending on our payment and business model."
"Pricing has recently been increased and the cost is a downside"
"In general, the pricing is competitive."
"The solution uses a licensing model that is reasonable compared to other products."
"The licensing model for Proofpoint Email Protection is simple. It's based on the number of users. Price-wise, Proofpoint Email Protection is a five out of ten because it's a pretty expensive solution."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"The solution is expensive."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
