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.

Secure email management improves through advanced filtering and dynamic virus scanning
Fortinet FortiMail offers capabilities like settings for mail delivery, mail filtering, spam controls, and email bursting prevention. It also allows for email forwarding, dynamic filtering, and scanning based on virus signatures. I can set varying levels of security. The tool is flexible and provides essential features for mail security and management.
George Kajaia - PeerSpot reviewer
Work hours are not lost searching through spam emails to determine which emails are legitimate
In history on the reporting graph, when you are trying to search for sender by address, it won't search by domain. I could send an email from SendGrid with my domain, but with SpamTitan, if you search by that domain then it wouldn't search it. It only searches from the field, not in the envelope field. Unfortunately, mass mailing companies, like SendGrid, send email with the form address and that completely differs from the domain envelope form address. There is no way to search for the envelope form. So, I gave them an idea to improve this filtering. For example, if I have to search an email sent by SendGrid, then I am forced to search by the recipient, then find the emails marked as spam. This is quite a huge hassle. They told me that they are aware of this and will try to add it, but they haven't added it yet. I would like to implement a secondary delivery pool for mass mailings, having an alternate pool for mass mailing lists since there is only a single mail queue with SpamTitan. For example, if 10,000 emails are being sent, then the queue will be large. Unfortunately, without a secondary delivery pool, legitimate emails will wait in the queue to be delivered to my email. Therefore, I would like to have two queues: one for everyday emails and another for mass mailings. Now, I have to decide whether to buy a second SpamTitan license just for this reason because I am very satisfied with the functionality of SpamTitan overall and don't want to use another sender's appliance for this. From 2020 to 2021, there was a huge switch in the types of spam coming in. SpamTitan's anti-spam should be enabled to catch this spam. The spam catching rate went down over the last three to four years. I think this is because spammers are evolving and using different methods to send spam emails. The phishing rate of SpamTitan is not great, even Exchange Online Protection catches phishing better than SpamTitan. The most worrying are the phishing emails. I would like SpamTitan to upgrade and improve the phishing catch rate. The sandbox of the Bitdefender engine is not working correctly. They sent me an email that they pulled it because it was not working as it was intended to work. So, they are working on this as well, and maybe the sandbox will be fixed. The sandbox is for viruses. If something goes through then it is sent to the sandbox for analysis. However, I am not using the sandbox right now. I am just quarantining this type of attachment right away.
