MessageLabs' headquarters are housed in three yellow-brick buildings near Gloucester. The buildings can only be entered by using a swipe card. Visitors must be announced 24 hours beforehand and have to be accompanied by a member of staff at all times.
The Network Operations Centre (NOC) monitors MessageLabs' customer infrastructure, and is the first line of defence in combating malicious code and spam. This part of the company scans all mail destined for a client, before deciding whether the mail is spam, contains malware or is safe.
The system in NOC used to monitor customers' email infrastructure and traffic is called 'Big Brother'. The monitor on the wall shows traffic and threats to customer servers, and threats within customers' emails.
