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.

Provides end-to-end antivirus protection and has good stability
Symantec Endpoint Protection provides end-to-end protection. Along with antivirus protection, it has a lot of key areas, including intrusive prevention, firewall features, and application and device control. It can integrate with other Broadcom solutions, such as Symantec Messaging Gateway and Symantec DLP. If you want to send an email, it gets scanned through endpoint protection and DLP. We get all Symantec functionality in a single pane.

Quotes from Members

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

Pros

"Defender helps us prioritize threats across our organization."
"Microsoft Defender for Office 365 is a stable solution."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"There are several features that I consider valuable."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The most valuable feature is NetFlow threat protection."
"What I like most about Symantec Advanced Threat Protection is its notification capability."
"The great advantage in using this product is it creates multiple services."
"All of the solution's features are quite valuable for us. We especially like the threat protection it provides."
"Currently we have 800-plus nodes connected with this solution, without any issues. The solution is scalable."
"Technical support is very responsive. You just have to open a ticket. They respond in a timely manner. Their response is good. I'm satisfied."
"You don't have to buy a separate email security platform. You can enable that using their endpoint, and I like that. You don't have to have two agents running on the same box."
"The most valuable feature is Click-time URL protection."
 

Cons

"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"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."
"We need a separate license and we don't know how to get the license that is required."
"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."
"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."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"An improvement could be made on the reporting because then it would be easier to collect information and submit it for compliance."
"The cloud platform needs to have improvement in terms of the user interface and the different capabilities it has available. It needs to match the other leading next-gen EDR products that are available in the market. That's the reason why we are stepping away from Symantec. Their cloud environment is just generally lacking in comparison to others."
"Symantec appliances need improvement. The whole appliance environment is a robust system and it needs a massive amount of storage space. If you have to increase or speed up the background storage it's a pretty complicated process. The scalability and sizing is critical, and if you do it wrong you run into issues pretty quickly."
"The security features need to be improved."
"The administration interface needs a lot of improvement. It should be UI based, and simple. They need to improve it. It's pretty much not that friendly compared to what we were using as Bitdefender before. It's okay but is improving, actually."
"Entire threat protection is not available for the advanced features."
"There are some ‎features that would add value to this product. One of them would be a graphical presentation of threats that the system has encountered."
"It also needs network-based threat protection for shared folders and files."
 

Pricing and Cost Advice

"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."
"It's a user-base subscription."
"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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing has become expensive."
"The product is very expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The price is quite expensive."
"Symantec Endpoint Protection has an average price."
"The pricing of this solution is inexpensive and affordable."
"Pricing is good. It is nice to have a great product at a fair price."
"Symantec Advanced Threat Protection's pricing is comparable."
