Its user interface is pretty old-fashioned, and sometimes, it's hard to find the features that you are looking for. The user interface definitely needs some improvement.

I don't need any additional features. It works very well, and it does the job.

The weaknesses of Trend Micro ScanMail are that it doesn't fully protect ad-based web access and lacks proper security for Outlook, iOS, and web browser access. As a result, I need to use multiple security products: ScanMail for regular email and another solution for securing Outlook web access. I would like to have a single security solution that covers all my email and web access needs.

The price could be better. I think it's pretty good compared to other solutions as far as the features are concerned. It basically covers most of the stuff which we require for email security. But it would be better if they made it a little cheaper and more cost-effective. That would make it easier for us to sell it.

ScanMail was one of the best solutions a few years ago, but it is no longer the best solution because of its old-fashioned management console. Customers associate it with something that is old because there is no change in the management console. It has old icons, and it is not fresh enough. It is also not easy to use or play with. The report engine is also old-fashioned. Customers want something easier, quicker, and cleaner. 

It should communicate with other products. For example, any information about spam or ransomware coming from one IP should be sent to perhaps a firewall or antivirus of a client to indicate that a particular source IP has to be excluded to avoid any ransomware problem.

The sandboxing part can be improved. 

They should also add standard and advanced management-type features. Some additional security for email cases should also be added in the next version.
