"Removal of spam, viruses and malware."

4/5

What do you like best about FortiMail?

I love Fortimail since I can configure it easily. It also helps me to filter spam effectively, in addition to quarantining potential spam for later review. I also like it because malware also attacks it in a timely manner. Simply put, it helps me protect my email from potential threats. In addition to this it is easy to handle and very flexible in every function. Review collected by and hosted on G2.com.

What do you dislike about FortiMail?

I think that the quarantine should check your more accurately, since sometimes there are emails that are there and are not spam. They should also invest a little in guides, tutorials and news about the program. It should be noted that updates are made not as recurring as previous months. Review collected by and hosted on G2.com.

Recommendations to others considering FortiMail:

Without a doubt, it is suitable for organizations with vulnerabilities or with recurring threats via mail. By implementing this tool, all those negative circumstances that refer to spam, viruses, malware will be attacked with the greatest potential and efficiency. It will do an effective job to keep your network secure and finally it is useful for small businesses and large companies. Review collected by and hosted on G2.com.

Create a POC with other ideas to see if it suits the company well. Review collected by and hosted on G2.com.

What problems is FortiMail solving and how is that benefiting you?

In our organization we have deployed the FortiMail Cloud solution and it is quite successful. The alternative is to buy an annual subscription in one, two or three years. The longer the rise, the lower the price, of course. FortiMail blocks emails very effectively. We have rendered proof with Proofpoint and FortiMail for idea checking. Our performance in filtering was almost equal to that of both. Fortimail, however, was one-third the cost. To stick to their solution is so much lower risk. I believe Proofpoint had a few other features in addition, but the price argument was not worth it. Review collected by and hosted on G2.com.
