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.

Effective threat prevention, reliable, and beneficial keyword blocking
The most valuable feature of SonicWall Email Security is the blocking of emails using keywords. If there are any particular keywords in the subject, that we want to block from receiving from a particular person we can do it. Additionally, the blocking of emails is easy. we can release that one and we can block some of the keywords also like that.

Quotes from Members

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

Pros

"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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 basic features are okay and I'm satisfied with the Defender."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"The product is not resource-intensive."
"Defender helps us prioritize threats across our organization."
"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."
"This excellent email gateway minimizes spam, inspects suspicious emails and isolates infected attachments with little administrative effort."
"The number of false positives is minimal."
"The anti-spam feature is very valuable."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"The most valuable aspects of this solution are that it protects us from spam and phishing attacks. We had a lot of attacks coming in and then we deployed this solution and they stopped. We no longer have any spam or phishing issues."
"Fortinet FortiMail is a complete product addressing mail security concerns. It helps to know spam subscriptions and create restriction policies."
"Troubleshooting is very simple because you can see where the email was not delivered and why it would be considered as spam."
"Fortinet FortiMail is easy to use and the detection rate is very good. You can customize content filters and profiles are done easily. Additionally, there is a sandbox integration feature that is good."
"Setup was easy. It took about 30 minutes."
"This solution provides very good email security that protects us against spamming and malware."
"The product is easy to manage in terms of configurations."
"There are no wasted extras and the interface is really simple."
"According to our customers, the product's most valuable feature is the ability to detect spam and reduce phishing emails."
"The anti-spam aspect of the solution is its most valuable feature."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
 

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."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"You should be able to deploy Defender for every subscription without the need to add servers."
"The phishing and spam filters could use some improvement."
"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."
"We need a separate license and we don't know how to get the license that is required."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"The GUI is sometimes slow to fetch the device report and could be improved."
"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."
"I think the security of the product could improve."
"I would like the integration to be easier."
"I have little to say about possible improvements, but the configuration for content blocking could be better. So, for example, if the email includes the line "You have a Bitcoin", I would like it to be easier to block it before it enters an inbox. Fortinet could maybe offer better or simpler help on how to do this properly."
"The biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
"The solution could improve by making the UI more user-friendly and increasing spam and threat detection capabilities."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"The area that could use some improvement in Fortinet FortiMail is the integration process. I would like the integration to be easier."
"There could be definition updates included in the subscription."
"We would like to see more information on a dashboard about what is happening when it comes to spamming and malware."
"The reporting needs improvement."
"Updates could be released more frequently."
"They should integrate the solution with third-party platforms."
"The technical support from the company is not always very good at solving issues, but they offer access to a good community of users where problems are easily solved."
"SonicWall Email Security could improve by making the file blocking and the release feature easier to use"
"They need well-trained partners in Nigeria."
