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.

Effectively reduces spam and malicious emails with reliable detection capabilities
It would be helpful to make it easier for end users to filter and see items in the quarantine within the Proofpoint Intelligent Compliance Platform. As an admin, I believe it would be sensible if end users could also see the quarantine folder in the Proofpoint Intelligent Compliance Platform so they can create their own rules. The reports are all predefined, and I cannot create custom reports, so I am not fully satisfied with their visibility. I would appreciate the ability to generate my own reports.

Quotes from Members

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

Pros

"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"With Defender for Office 365, we have been able to increase the security posture across our organization."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The product's scalability is good."
"Microsoft so far has been good; we haven't faced any kind of disruption or anything else, it's a good product and good platform, I must say, and overall it's a good product and good service and we haven't dealt with bugs or glitches."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"Our experience with the platform has been positive as it has maintained consistent control over spam and malware threats."
 

Cons

"The custom alerts have to improve a lot."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"The product must provide better malware detection."
"We are always looking for other tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"If you look at other products, such as Wiz or Palo Alto's cloud, because they also have similar components in terms of how they protect cloud infrastructure or enable cloud security, Microsoft Defender for Office 365 is not up to that extent."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The Proofpoint Intelligent Compliance Platform does not provide features that help reduce manual efforts, so additional human resources are still required to manage security."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"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."
"The license is expensive because the cost is based on the number of users."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"The product is 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."
"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."
