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

"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"It has significantly decreased my time to detection and response."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Microsoft Defender for Office 365 is a stable solution."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"The stability of Microsoft Defender for Office 365 is fantastic."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Spam protection is the most valuable feature."
"I like Avanan's SmartDLP module. It's seamless, and the administrative overhead is low. We aren't a very sophisticated operation. We just want to reduce our exposure, so we find ThreatCloud helpful. Avanan's acquisition by Check Point was beneficial for them."
"The ease of installation and the AI capacity of the product are valuable."
"Email inspection has saved many employees from spam attacks and viruses from unauthorized sources."
"Email Attachment Protection detects any insecure files and quickly blocks them to prevent the spread of viruses to other secure documents."
"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."
"The program has reduced the dangers related to phishing, malware, ransomware, and other vulnerabilities."
"It is simple to deploy this platform and interact with the set features."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

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."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"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."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Configuration at the mid-level could be improved for the support team."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"It should reduce the amount of time needed for thorough scanning."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"The system response in a slow computing device affects performance when sending and receiving emails."
"The system could be designed to give corporate emails first priority due to demands."
"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."
"They should come up with a mobile application so that it can be more flexible."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"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."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"The product is expensive."
"I know that the product is incredibly expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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."
