i love how customizable it is with many options you can use from whitelisting all attachments or just specific ones! very user friendly especially for new users! nothing really but its ok and good overall a great product keep using this software! we at my current employer have started implementing everything Avanan so far has recommended to us which includes email scanning and DLP filtering out certain file types like image and video files ect. I like how easy it is to set up new rules/policies with this software. It's very user friendly and not too technical of an application. There isn't much out there right now that can take over someones email without them knowing about it. If you want something simple but effective then use this product. We're using this along side our existing anti virus/antimalware solution so we have complete control over all aspects of my users emails when they are logged into our system.
