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

"The email protection is excellent, especially in terms of anti-phishing policies."

"The good part is that you don't have to configure it, which is very convenient."
"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.

Cons

"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The XDR dashboard has room for improvement."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"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."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Microsoft Defender for Office 365 should be more proactive."

"The platform's control panel needs enhancement."

"The technical support from the company is not always very good at solving issues, but they offer access to a good community of users where problems are easily solved."
 

Pricing and Cost Advice

"The license is expensive because the cost is based on the number of users."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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."
"The pricing has become expensive."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."

"Email Security Gateway's pricing is good."
"I rate the application’s pricing a five out of ten."
"The platform offers a yearly license."
"The overall price of SonicWall Email Security should be reduced and there should be an option to purchase one or two licenses more instead of their current policy of bulk increases only. There should be more flexibility in the licensing model. Each license cost approximately $33 annually."
"The cost is cheaper than Sophos. I would rate it as five out of ten."
"We have a two-year license subscription and the price is very high."
"Our customers purchase the solution's yearly license."
