A strong feature set makes McAfee’s Security Internet Gateway (SIG) a heavy hitter in any organisation’s architecture. The SIG provides anti-virus scanning against all protocols, while anti-spyware scanning blocks potentially harmful spyware, cookies and adware from getting on to the network. To protect against spam the SIG uses an engine consisting of anti-spam, anti-phishing rule sets, permit-or-deny lists and a spam-learning feature. The SIG enforces policy and compliance issues regarding out-going data transmission as well as some forms of data leakage. This appliance is easily configurable by IT staff and, once configured, requires minimal administrator intervention.
