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 most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The product is not resource-intensive."
"One of our clients didn't have the budget to invest in a SOC team, but we deployed the solution for them, and they now run a SOC with only one analyst."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"It definitely is a must for email protection and O365 app DLP, and combined with Microsoft Defender for Endpoint, Microsoft Defender for Identity, and MCAS, it provides a holistic solution for threat protection, email protection, O365 apps protection, and DLP for both internal and external risks."
"The product's scalability is good."
"The initial setup was easy."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"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

"Its price should be improved. Its cost is a major concern for us."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"There is room for improvement in terms of reporting."
"Several simulation options are available within 365, and the phishing simulation could be better."
"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

"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"I know that the product is incredibly expensive."
"The product is expensive."
"The license is expensive because the cost is based on the number of users."
"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."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
