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.

Offers advanced protection from email-based attacks and consistently blocks spam
The most valuable features are Fortinet FortiMail ( /products/fortinet-fortimail-reviews )'s ability to protect from advanced features of email-based attacks, including protection against ransomware and malware attacks. It is especially effective in blocking spam through standards like wrong source IP for email-based attacks. Its high scalability and stability, especially for financial institutions, are noteworthy.
Amey Darekar - PeerSpot reviewer
Has an easy implementation phase to deal with for users
I primarily use the product in our daily security operations since it is implemented in all of our company's systems and is used in our environment. Normally, email security tools like FireEye or Trellix help to protect ourselves from spam, malware, and other email-oriented threats. The tool is used extensively in our company's environment. It is more like a collaboration email security that is used in our company. Whether my company plans to increase the number of users of the product or not is something that depends on the growth of the organization. I recommend the product to those who plan to use it. The product is stable and reliable, considering the results my company gets out of it. When it comes to Trellix or FireEye Endpoint Security (HX), the tools offer antivirus as well as the modern real-time security feature, which is used to automate the detection and protection of the endpoints against all the security threats that are currently there in the industry. I don't see any challenges with the integration part of the product, but since a different team manages it, I don't have visibility into it. In terms of the value offered by the product, the solution does help our company protect data and the complete infrastructure. I rate the tool a nine out of ten.

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."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"Scalability-wise, I do not think there are any issues so far."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"Fortinet FortiMail's most valuable features are its performance and security."
"I like the anti-spam and security features of Fortinet FortiMail, and that its features complement each other."
"The integration with FortiSandbox is good, and something that we utilize often."
"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."
"It can block a lot of fake emails."
"I am satisfied with both the scalability and the stability of this solution."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"It is one of the most efficient solutions in our environment. We have more than nine hundred users. All of these users are protected by Fortinet FortiMail."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
"The product protects my email."
"We have had very good results from the use of FireEye Email Security. We are very comfortable with this technology, but I don't know if it's necessary to move into the cloud, we will check other technologies and study them. Additionally, the solution has good integration."
"The initial setup is simple."
"FireEye is good for malware depicting and security."
"The product helps reduce the number of malicious emails reaching the user's inbox."
"I like FireEye's filtering, spam digests, and its advanced threat review of email flow. It also has a broad range of riskware rules you can deploy."
"What I find most valuable with the solution is that it can integrate with cloud solutions, such as Google and Microsoft. Additionally, the solution is easy to use."
 

Cons

"We need to be able to whitelist data at the backend."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"The XDR dashboard has room for improvement."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"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."
"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."
"Several simulation options are available within 365, and the phishing simulation could be better."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"In the Latin America market, some spam messages use Portuguese language. Some clearly spam messages would be better identified by the anti-spam if not for the language."
"The tool needs to improve its pricing policy. Also, it needs to be more user-friendly. I would want it to improve email security as well."
"Online support sometimes takes up to a week to get back to you."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"Fortinet FortiMail's technical support team has shortcomings and needs improvement."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"In general, our company should make the tool more robust to protect our systems."
"I would like the solution to be able to automatically quarantine the malicious emails before getting to the user's mailbox and continue with regular email operations. This could result in the user clicking the email before the purge operation is completed."
"The custom tailoring is limited."
"The solution must provide features to scan QR codes for threats."
"There is a need for improved integration with totally different products, such as a rapid server."
"The solution is not easy to set up. However, we have employees that have the knowledge that can do the difficult implementation. It would be better if the process was easier."
"I would rate them as a 1.5. The new hub created in India is not good."
"FireEye needs single sign-on. They say it's on their roadmap. They should also implement support for Microsoft Authenticator app for 2FA."
 

Pricing and Cost Advice

"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."
"The license is expensive because the cost is based on the number of users."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."

"The product is very expensive."

"The product is expensive."

"I have no information on pricing for the competition because right now, my company is working only with Fortinet, but I can say that in general, the price for Fortinet FortiMail was accepted by the customers easily. The POC is also important when a customer is buying a solution. The customer wants to see how the product runs, and as Fortinet FortiMail is a stable product that runs without big issues, it has a bigger chance of getting chosen by customers over its competitors, even if its price may be a little higher.
