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 Spam Firewall 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 Spam Firewall 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.
Denial of Service (DoS) Attack 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 Spam Firewall is positioned to stop spammers before they overload an email server.
