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.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

A simple and easy-to-handle solution that does not need multiple configurations, but its pricing could be improved
Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations. A single IT admin supporting over 100 or 200 users can easily understand everyday reports. Trustifi Inbound Shield is a user-friendly solution that even simple lay people can understand. The product helps our customers avoid 95% of unwanted phishing emails.

Quotes from Members

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

Pros

"Since we have started using the solution, there have been fewer compromises."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The good part is that you don't have to configure it, which is very convenient."
"The technical support is good and quick to resolve issues."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The ability to respond to threats if very important."
"Microsoft Defender for Office 365 is a stable solution."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"It can retract unsafe emails and remove them from the entire communication channel."
"The customizable rules allow you to change aspects."
"Email encryption enhances end to end security of any data before it passes through the networking system."
"Avanan is a stable software. My company hasn't faced any issues, bugs, or problems with the performance of Avanan."
"This technology is one of Check Point's acquisitions, and it is currently a powerful tool that provides all the protection that is not found in other tools."
"Email Attachment Protection detects any insecure files and quickly blocks them to prevent the spread of viruses to other secure documents."
"Email inspection has saved many employees from spam attacks and viruses from unauthorized sources."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"There is a different console for different things; I just want one consolidated console."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"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."
"You should be able to deploy Defender for every subscription without the need to add servers."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The cost can be reviewed to enable SMEs to acquire it and enjoy great security features."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"The user experience must be improved."
"Familiarization with performance for new teams may take a long time."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"Sometimes it seemed like the allow list wasn't working. I've created many allow list rules however, they still seem to be blocked; the same is true with the blocked list rules."
"It should reduce the amount of time needed for thorough scanning."
"It is very difficult to find the required documentation."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The license is expensive because the cost is based on the number of users."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"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."
"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."
"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."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"The pricing of Avanan is reasonable."
"Good pricing arrangement as an SaaS offering."
"Avanan’s price is comparable to Barracuda."
"The product is not the cheapest in the market."
