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.

Reasonable pricing and good spam filtering but does not offer robust gatekeeping
It's mainly suited for mid-size companies, not for bigger companies like us. We are more than 1,000 people. In fact, we're over 2000 users, so that's why we investigated some other products, and Clearswift, for example. We likely won't increase usage. We're looking at GFI in a year or so.

Handles security, malware and spam of email systems
We use Email Security Gateway on email systems for handling security, malware, and spam.  The solution is easier to manage than FortiMail. You can implement policies easily.  The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very…

Quotes from Members

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

Pros

"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"The basic features are okay and I'm satisfied with the Defender."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The product's scalability is good."
"Defender helps us prioritize threats across our organization."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The deployment is simple and once up and running it is easy to manage."
"It actually filters the compromised emails when on a network layer itself."
"One major benefit of the Fortinet FortiMail product is its ease of management."
"I would rate Fortinet FortiMail ten out of ten overall."
"The most valuable feature of this solution is the spam filter."
"FortiMail possesses notable strengths, and one key feature is its store-and-forward concept."
"The anti-spam functionality is good and works well."
"I love the integration between Fortinet products."
"It helps reduce spam and phishing attacks."
"The solution is easier to manage than FortiMail. You can implement policies easily."
 

Cons

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"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 needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"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."
"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."
"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."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"There are features that other solutions have that this one is lacking, such as reporting options. I hope in future releases they advance their features list."
"Limited ability to upgrade hardware may lead to some performance issues that might otherwise be improved."
"The infrastructure could be improved."
"A room for improvement in Fortinet FortiMail is that it only has a hardware version. I also didn't find the solution scalable, so that's another area for improvement."
"The solution could improve by making the UI more user-friendly and increasing spam and threat detection capabilities."
"Maybe FortiMail's integration could be better."
"The solution lacks to provide more visibility when there is a problem, and it needs to be tracked."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"Its pricing could be affordable."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
 

Pricing and Cost Advice

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"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 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."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."
"There is a license required for this solution and it is on an annual basis. I am satisfied with the price."
"FortiMail is not cheap."
"This is a good solution and value for the money."
"We paid approximately $30,000 for the solution. It is less expensive than some other solutions. We have one license that carries all the features that we wanted."
"The licensing model for this solution is better because it is based on the box and not the number of users."
"Fortinet FortiMail has an annual license agreement."
"Compared to its competitors, Fortinet's products are available at a higher price range."
"Email Security Gateway's pricing is good."
