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.

Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.

Quotes from Members

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

"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"Since we have started using the solution, there have been fewer compromises."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"They are very easy to use."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"Trend Micro effectively detects and blocks NAS devices and identifies potential threats."
"The most important feature is behaviour detection."

"Trend Micro Worry-Free Services Suites has an inbuilt auto scan facility. It is very good at detection and response, and it includes a web filtering option."
"The load balancer feature is excellent."
 

Cons

"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"We need to be able to whitelist data at the backend."
"I'd like some additional features any product can give me to protect our environment in a better way."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Email security checks contain a small number of false positives."
"Network vulnerability scanning could be improved."
"The solution's documentation is not good, and I'm struggling to change global configurations."
"Trend Micro should improve its Worry-Free Services Suites, particularly the agent for Windows operating systems."
"The solution’s scalability is limited."
"The licensing aspect seems costly, and the license cost increases yearly, which is a concern for us."
"The EDR part of the product is an area of concern where improvements are required."
"Trend Micro Worry-Free Sevices Suits' pricing remains a concern for our non-profit organization. Despite receiving some discounts, we find the pricing on the higher side."
"The log management feature needs to be improved, specifically, the ability to send logs from the console via API."
 

Pricing and Cost Advice

"It's a user-base subscription."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"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."
"I know that the product is incredibly expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."

"The product is very expensive."
"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."
"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
"The product is available at a very good price point."
"We pay a yearly licensing fee for the solution, which is too expensive."
"I rate the tool's pricing a five out of ten."
