For services such as e-mail, FTP & VPN services it is necessary to expose parts of the server to the internet. This of course represents a potential security risk such as malicious hackers and e-mail spammers to name but two. It is therefore paramount that you "lock down" the system to ensure only valid users have access to these services. A Mach One consultant will assess your requirements based on risk of attack, number of users, network traffic and budget then put together a package for the supply and installation of a solution along with the ongoing support and security monitoring by Mach One.
