"Spam & virus free email without changes to your infrastructure"

You want to protect your email environment against spam , viruses and unwanted content. Spam represents nowadays over 85% of the total amount of  mail you would normally receive on your own mail server and is a burden for your internet connection, the mail server, the backups and most importantly your personnel. It's not only the irritation; it is above all the time spam consumes for employees with looking at the mails, whether to decide it's spam and deletion. Furthermore spam harbours a significant security risk. The intention of spam is to lure ignorant users to a website with the intention to sell you something, or is a fake website of your bank. The majority of these sites tries to exploit an (un)known leak in your internet browser in order to install malicious software (malware). The consequence can be that a user thinks he is using his well known and trusted internet banking application but in reality he is connected to a rogue website that is the spitting image of the real one. The consequences are clear.
