Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Quotes from Members

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

Pros

"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"There are several features that I consider valuable."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"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."
"Scalability-wise, I do not think there are any issues so far."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"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."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"Menlo Security RBI's best feature is its threat isolation engine."
"I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace."
"The solution scales well."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
"The Tap and Trap features. They are the best features."
"Proofpoint Email Protection's advantage is that, when it's working properly, it tends to catch more threats as compared to other products."
"I recommend all of my customers to migrate and start using Proofpoint as it is secure, minimizes risk, and eliminates phishing attacks."
"The anti-spam features are excellent on the email firewalls."
"The tool has improved our workflow by ensuring people receive only the emails they need for work rather than being inundated with hundreds or thousands of unnecessary emails daily."
"The solution is very user-friendly."
 

Cons

"We need a separate license and we don't know how to get the license that is required."
"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 UI needs to be more user-friendly."
"There's room for improvement regarding the time frame for retrieving emails."
"Configuration at the mid-level could be improved for the support team."
"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."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"Pricing for the platform could still be cheaper."
"Proofpoint Email Protection is an expensive solution."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"Proofpoint Email Protection could improve by reducing the price."
"The solution should add post-sales training."
"The flexibility of the solution can be improved."
"Phishing detection could improve further to match some of the capabilities offered by competitors."
