Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Centralized archiving has transformed how we manage compliance, audits, and investigations
Overall Proofpoint Intelligent Compliance Platform is a strong platform for compliance and information governance, but there are a few areas where it could improve in the future. One improvement area is the user experience and interface consistency across different modules. Some workflows can feel complex, especially for a new user or the team managing multiple compliance functions simultaneously. Community feedback has also highlighted that certain administrative interfaces and navigation flows could be more modern and streamlined. I also think there is room for improvement in support responsiveness and operational simplicity for complex deployments. Some users in the community have mentioned challenges around the ticket response time and troubleshooting efficiency for advanced configurations that needs to be improved. From a product perspective, a continued investment in AI-driven detection, the reduction of false positives, and easier policy tuning would make the platform even more effective at scale. Proofpoint already provides strong automation and machine learning capabilities, but a highly regulated environment still requires significant tuning and oversight to optimize the workflow. One additional improvement for Proofpoint Intelligent Compliance Platform would be making policy configurations and workflow management more intuitive, especially for organizations with complex compliance structures and multiple regulatory requirements. I also think more customizable dashboards and reporting capabilities would help teams gain faster operational insight and improve visibility into the compliance trends, investigations, and reliable workload.

Quotes from Members

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

Pros

"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"The feature of Microsoft Defender for Office 365 that I like the most is probably the email features specifically, because those are the ones that a typical end user will accidentally click on a link not knowing what it is, and it'll catch it, and then it'll feed it over to Defender and stop the attack from happening before it actually can."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"Microsoft Defender for Office 365 is a cloud-based email filtering service that helps protect our organization against unknown malware and viruses by providing robust zero-day protection and includes features to safeguard our organization from harmful links in real-time."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Our experience with the platform has been positive as it has maintained consistent control over spam and malware threats."
"Overall, Proofpoint Intelligent Compliance Platform is a very strong and reliable platform for compliance, archiving, supervision, and information governance."
 

Cons

"I was looking for some advanced features, like if I would receive an email that contains a legitimate file type, but the content is malicious, how I can protect against that?"
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"The GUI is sometimes slow to fetch the device report and could be improved."
"The XDR dashboard has room for improvement."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"You should be able to deploy Defender for every subscription without the need to add servers."
"The UI needs to be more user-friendly."
"The Proofpoint Intelligent Compliance Platform does not provide features that help reduce manual efforts, so additional human resources are still required to manage security."
"Some workflows can feel complex, especially for a new user or the team managing multiple compliance functions simultaneously."
 

Pricing and Cost Advice

"The product is very expensive."
"It's a user-base subscription."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The pricing is normal. Considering its popularity, it's not overpriced."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The product is expensive."
