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…

Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

"Menlo Security RBI's best feature is its threat isolation engine."

"I like the product's ZAP feature."
"It provides security to both on-premises and Azure infrastructures."

Cons

"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The pre-sales cost calculations could be more transparent."
"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."
"The product must provide better malware detection."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Configuration requires going to a lot of places rather than just accessing one tab."

"Some of the searchability when looking for specifics in Exchange logs is tedious."

"When the product is being updated, it changes some of the setups. The support team is also not good."
"The security features could be better."
"It would be helpful for customers if Plan 1 features were included with EOP."

Pricing and Cost Advice

"I know that the product is incredibly expensive."
"The pricing has become expensive."
"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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It's a user-base subscription."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Menlo Security RBI can be very costly."
"The product is bundled with Microsoft 365."
"It is a low-price solution."
"Online Protection is fairly expensive."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The solution is expensive but is backed by Microsoft's reputation."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The price of Microsoft Exchange Online Protection is reasonable."
