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.

Stable and scalable solution with a great threat isolation engine
Menlo Security RBI is mainly used to do basic cloud migrationary technologies Menlo Security RBI's best feature is its threat isolation engine. Menlo Security RBI could be more cloud-friendly, and its mobility could be improved. In the next release, I'd like Menlo Security RBI to include a…

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's most valuable feature is its performance."
"The email protection is excellent, especially in terms of anti-phishing policies."
"The deployment capability is a great feature."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"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."
"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."
"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."
"Menlo Security RBI's best feature is its threat isolation engine."
"A one-stop shop for email protection"
"The solution's technical support is good. I rate the technical support a ten out of ten."
"It's the top choice because no company can operate without security. Ensuring email protection is a major priority for any organization when building its infrastructure."
"The solution is very user-friendly."
"Provides better control over emails, especially those sent via Office 365 on the cloud."
"Proofpoint Email Protection is a good product, and its most beneficial feature is the Threat Response Auto-Pull. I also like that it's an integrated email security solution."
"The most valuable feature of Proofpoint Email Protection is the central location dashboard for viewing all the related information for risk."
"The Phish Alarm button allows users to submit questionable emails for review and complete analysis."
 

Cons

"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"Several simulation options are available within 365, and the phishing simulation could be better."
"There's room for improvement regarding the time frame for retrieving emails."
"We need to be able to whitelist data at the backend."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"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."
"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."
"The stability and UI are the two areas of the solution with certain shortcomings that need improvement."
"There is room for improvement in detecting and preventing phishing attacks. While the solution performs well in some aspects, it struggles with phishing threats."
"The high cost of the product is an area of concern where improvements are required."
"Integration for reporting needs to be improved, it's too complex."
"You only receive one model in Proofpoint Email Protection and the other ones you have to purchase at a high price. There should be more available with the solution and additional models should be less expensive."
"The false positives are an issue."
"Pricing for the platform could still be cheaper."
"The solution should add post-sales training."
 

Pricing and Cost Advice

"The pricing has become expensive."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
