Energize Updates Minimize Administration and Maximize Protection
To provide you with maximum protection against the latest types of spam and virus attacks, Barracuda
Networks maintains a powerful operations center called Barracuda Central. From this center, engineers
monitor the Internet for trends in spam and virus attacks and post updated definitions to Barracuda
Central. These updates are then automatically retrieved by your Barracuda Spam Firewall using the
Energize Update feature.
By spotting spam trends early on, the team at Barracuda Central can quickly develop new and improved
blocking techniques and virus definitions that are quickly made available to your Barracuda Spam
Firewall.
Energize Updates provide your Barracuda Spam Firewall with the following benefits:
■ Access to known offending IP addresses
■ Known spam messages instantly blocked
■ Known spam content blocked
■ Virus definitions constantly updated
