Barracuda's Advanced Threat Protection (ATP) combines behavioral, heuristic, and sandboxing technologies to protect against zero hour and targeted attacks. ATP automatically scans email attachments in real-time; suspicious attachments are detonated in a sandbox environment to observe behavior. In addition to blocking the attachment, the results are integrated into the Barracuda Real Time Intelligence System providing protection for all other customers.

With a long-standing heritage in spam protection, Barracuda Networks remains the leader in identifying and blocking spam. A comprehensive set of security layers ensures that organizations remain productive in the face of evolving threats.
The Barracuda Email Security Gateway leverages Barracuda Central to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware domains. Its industry-leading techniques protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.
As virus attacks become more sophisticated, email infrastructures require advanced virus protection. The potential for the destruction and release of information, or the disruption of a network, severely impacts productivity and can lead to financial loss.
The Barracuda Email Security Gateway scans email and incoming files by using three powerful layers of virus scanning technology. It also decompresses archives for complete protection. Powerful virus definitions are automatically updated via Energize Updates to maintain the latest protection against email-borne viruses.
To provide protection from tainted internal email, a Microsoft Exchange Plug-In safeguards organizations against the spread of viruses that don’t access the email gateway. The virus definitions are also regularly updated to ensure the most current protection.
Not every attack is focused on viruses, getting users to send their credit card number, or clicking on a malicious link. Often, the objective of the attack is focused on compromising or completely disabling a network. As a device that sits in front of an email server, the Barracuda Email Security Gateway is positioned to stop spammers before they overload an email server.
The Barracuda Email Security Gateway ensures that email can still be delivered even during email server failures or loss of connectivity. In the event of on-premises disruptions, email can be spooled in the Cloud Protection Layer (CPL) for up to 96 hours. An alternate destination can also be specified if delivery to the primary destination fails.
During email server outages, the email for all mail servers is visible through the Cloud Protection Layer. From the message log, administrators can see the status of all spooled emails and whether email has been re-delivered
The Barracuda Email Security Gateway is integrated with a cloud-based service that pre-filters email before delivery to the onsite Barracuda Email Security Gateway. The Cloud Protection Layer is continuously updated with definitions in real time from Barracuda Central. In addition, Barracuda’s global cloud infrastructure provides the flexibility to handle email surges during specific periods of the day and during Denial of Service attacks.
The Cloud Protection Layer ensures that an organization’s email security infrastructure scales with the increasing growth in email volume, attachment sizes, and the organization as a whole. By leveraging the bandwidth and computing power of the CPL, organizations can easily scale their email security solution.
