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.

Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.
Girish Vijay - PeerSpot reviewer
A stable and reasonably priced solution that performs well and has a very good malware database
Since Symantec merged with Broadcom, they might have lost some good technical engineers. Maybe that’s the reason why the product is performing poorly. When we have a good marketing and sales team, even though our product cannot perform, we will sell it at a high price because of the buzzwords. However, at the end of the day, the product should perform. Most of the products might not perform. Symantec is a very good product, but the services are basic. I rate the technical features of the product a nine out of ten. However, I would rate the services provided by the solution a six out of ten. Overall, I rate the tool an eight out of ten.

Quotes from Members

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

Pros

"There are several features that I consider valuable."
"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."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The product's scalability is good."
"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."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
"It is a solid and stable product."
"The most valuable feature of the solution is the content filtering policies because the solution offers huge options for configuration, such as hardware manipulation, et cetera, and the dictionaries make the work easier."
"The setup is pretty simple."
"The most valuable features of Symantec Messaging Gateway are advanced content filtering, malware, and antivirus defense."
"The solution is highly customizable. You can make rules for domains and configure policies for spam or malware. Messaging Gateway is an on-prem solution, so it's useful for companies without a cloud presence."
"The solution is "set and forget". You pay for it and everything is done for you."
"Symantec’s spyware and malware signature database is very good compared to other products."
"Symantec Messaging Gateway has a good GUI, and it is very powerful in detecting viruses and spam."
 

Cons

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"The pre-sales cost calculations could be more transparent."
"There is a different console for different things; I just want one consolidated console."
"We need to be able to whitelist data at the backend."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Scalability is lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong."
"The functionalities could be improved, such as the isolation feature."
"They have updated the version of the Messaging Gateway and the new features they are adding the need to be re-evaluated. They have done some changes on the policy."
"Messaging Gateway's advanced malware detection could be improved."
"What's lacking when you compare it with Proofpoint and other threat protection solutions is that it does the basic stuff, but we need more advanced threat handling."
"It is a nice product but is not user friendly in terms of the graphical interface. It is poor and is not rich in terms of the human interface."
"Symantec Messaging Gateway can improve detection because most of them are false negatives or false positives that we are trying to troubleshoot. Additionally, we are having routing problems and they are somehow connected to DNS issues."
"It will provide Excel reports and PDF reports, but it would be great if they supported the concept of Crystal Reports."
"The product must improve the user dashboards."
"The biggest problem is it's an on-prem product and we're trying to get out of having equipment in data centers."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The product is very expensive."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
