Barracuda Networks Real-Time Protection

Barracuda Real-Time Protection draws from the largest and most diverse installed base in the industry to detect early trends in email-borne threats. Once Barracuda Central engineers identify a potential virus or malware outbreak based on the frequency, diversity of sources and the metadata about the message itself, Barracuda Central validates the hypothesis by collecting samples of suspect emails from Barracuda Spam Firewalls around the world that elect to participate in data collection.

Immediately upon virus or malware classification, Barracuda Central responds to any Barracuda Spam Firewalls submitting the corresponding fingerprints with an instruction to immediately block the message, stopping the attack in real time and providing the fastest response to email-borne virus threats in the industry.

Further, after identifying new virus and other malware outbreaks, Barracuda Central automatically distributes new spam and virus definitions to all Barracuda Spam Firewalls through Energize Updates. Upon receiving the next Energize Update, the Barracuda Spam Firewall can block the virus or spam variants associated with the new outbreak via the Barracuda Spam Firewall’s traditional antivirus protection layers.
