Anti-Virus Protection

As virus attacks become more sophisticated and complex, email infrastructure requires 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 Essentials for Email Security scans email and incoming files using three powerful layers of polymorphic virus scanning technologies.

It also decompresses archives for complete protection. Powerful virus definitions are automatically updated to maintain the most up-to-date protection against email-borne viruses.

Anti-Spam Protection

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 Essentials for Email Security leverages Barracuda Central to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware domains.

It leverages many of the same industry-leading techniques found in the Barracuda Spam Firewall that protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.

Anti-Phishing & Anti-Malware Protection

The Barracuda Essentials for Email Security combats phishing attempts by combining anti-fraud intelligence, behavioral and heuristic detection, protection against sender spoofing (i.e., spammers spoofing valid email addresses), along with domain name validation to detect and block phishing attempts.

The Barracuda Essentials for Email Security leverages the cloud for dynamic, real time threat analysis, attachment sandboxing and URL protection to prevent malware from affecting email users.

Advanced Threat Protection

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 System providing protection for all other customers.

Link Protection

A popular method that attackers use to deliver malware relies on URLs that contain malicious code, which can be invisibly downloaded and can trigger a much larger attack.

Link Protection automatically rewrites these URLs so that the Barracuda Essentials for Email Security can sandbox the request at click time to block malicious links.

Typosquatting Protection

More sophisticated attackers make clever modifications to URLs so they look genuine, but are not.

The most common technique is omitting letters or using convincing “typos” that even users who check URLs before clicking often miss.

Barracuda’s Link Protection includes typosquatting detection, which automatically identifies and redirects these URLs to our sandbox at click time to block malicious activity.

Agentless Email Encryption

he Barracuda Essentials for Email Security offers a number of encryption features without requiring complicated key management. It is fully integrated with a cloud-based email encryption service for outbound email. Emails that match predefined policies are sent securely via TLS to the Barracuda Message Center.

The Barracuda Message Center uses AES with 256-bit keys to encrypt emails. To encrypt email traffic between sites over the Internet, the Barracuda Essentials for Email Security supports SMTP over TLS. This can be used between organizations that leverage a Barracuda email security solution or other email servers that support SMTP over TLS.
