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 deployment capability is a great feature."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"The basic features are okay and I'm satisfied with the Defender."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"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 initial setup was easy."
"There are several features that I consider valuable."
"The ease of installation and the AI capacity of the product are valuable."
"Email encryption enhances end to end security of any data before it passes through the networking system."
"Email Attachment Protection detects any insecure files and quickly blocks them to prevent the spread of viruses to other secure documents."
"When we don't understand some functionalities, the customer support staff responds fast to our calls and provides immediate action."
"It can retract unsafe emails and remove them from the entire communication channel."
"The customizable rules allow you to change aspects."
"Easy to use for non-technical users."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"The phishing and spam filters could use some improvement."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"The UI needs to be more user-friendly."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"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."
"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."
"The system could be designed to give corporate emails first priority due to demands."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"It should reduce the amount of time needed for thorough scanning."
"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 is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"Being cloud first and because we are in the movie business, we use a lot of Macintoshes. So, there is absolutely no reason for us to have Active Directory whatsoever. However, if you are using Office 365, you must have Active Directory in order to reset passwords. Even though we have a single sign-on provider, we must have Azure Active Directory for Office 365, which is really stupid. As a cloud application, you would think that I don't need Active Directory, which I don't need for anything else except Office 365. We have one server inside that space to help us manage Active Directory just for Office 365. This is a very sore point, but it is what it is."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"The system response in a slow computing device affects performance when sending and receiving emails."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"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."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The product is expensive."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"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."
"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 pricing of Avanan is reasonable."
"Avanan’s price is comparable to Barracuda."
"Good pricing arrangement as an SaaS offering."
"The product is not the cheapest in the market."
"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."
