We use ClearIn to scan our emails for viruses before we open them. It does this very quickly at no additional cost! There's nothing that I don't like about it. If you're looking for an easy way to ensure your employees are safe from malware when they send or receive eMails then look into clearing their messages through ClearIn today!! They offer excellent customer service too which is always reassuring as well. You can trust ClearIn because every time one of my staff opens an attachment or clicks on any links within these attachments there has never been anything found wrong with the process (or so far anyway!). I'm sure if something was detected there would be some sort of notification given but I haven't had issues yet myself.
