Spam Filtering

In a world dependent on email communication, one of the most frustrating things businesses have to deal with is email spam.  Fortunately, various technologies exist which empower providers to conduct spam filtering and reduce the amount of unwanted or unsolicited mail.

J&S Electronic Business Systems has partnered with Barracuda Networks, the #1 spam filtering technology on the market today, to deliver a solution that removes this frustration.  Here are some of the features you’ll enjoy:

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 Spam & Virus Firewall 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 & Virus Firewall that protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.

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 Spam & Virus Firewall scans email and incoming files 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 most up-to-date protection against email-borne viruses.

To provide protection from tainted internal email, a Microsoft Exchange Plug-In allows organizations to protect against the spread of viruses that don’t access the email gateway. The virus definitions are also regularly updated to ensure the latest protection.

Barracuda Central

All Barracuda products are supported by Barracuda Central, a 24×7 advanced security operations center that works continuously to monitor and block the latest Internet threats. Barracuda Central collects data from more than 150,000 collection points worldwide and analyzes it to develop defenses, rules, and signatures. As new threats emerge, Barracuda Central is quick to respond to early outbreaks and delivers the latest definitions through Barracuda Energize Updates. These updates require zero administration and ensure that the Barracuda Spam Firewall provides comprehensive and accurate protection against the latest Internet threats.

Denial of Service (DoS) Attack Protection

Not every attack is focused on getting users to send their credit card number, getting users to click on a malicious link, or to plant a virus. Often, the objective of the attack is focused on disabling a network or mitigating its effectiveness. As a cloud-based service, the Barracuda Spam Firewall is positioned to stop spammers before they overload an email server.

Email Spooling

The Barracuda Spam & Virus Firewall 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 for up to 96 hours. An alternate destination can also be specified for delivery, 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, you can see the status of all spooled emails, and whether mail has been re-delivered.

Spam and Virus Pre-Filtering

The Barracuda Spam & Virus Firewall is integrated with a cloud-based service that pre-filters email before delivery to the on-site Barracuda Spam & Virus Firewall. The Cloud Protection Layer is continuously updated with definitions in real time with updates from Barracuda Central. The elasticity of 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 and attachment sizes; as well as the growth of companies. By leveraging the bandwidth and computing power of the CPL, organizations can easily scale their email security solution.

Encryption *

The Barracuda Spam & Virus Firewall offers a number of encryption features. It is fully integrated with a cloud-based email encryption service for outbound email. Email that matches policy or are marked for encryption via the Barracuda Outlook Add-in are securely sent via TLS to the Barracuda Message Center.

The Barracuda Message Center uses AES with 256-bit keys to encrypt email. To encrypt email traffic between sites over the Internet, the Barracuda Spam & Virus Firewall Message Transport Agent supports SMTP over TLS. This can be used between Barracuda Spam & Virus Firewalls or other email servers that support SMTP over TLS.

Outbound Filtering **

Outbound filtering prevents organizations from being put on spam block lists and prevents sensitive data in email from leaving the organization. Employees can inadvertently cause internal systems to become a source for botnet spam. Using a subset of its defense layers, the Barracuda Spam Firewall’s outbound filtering stops outbound spam and viruses. It also lets administrators enforce content polices for data loss prevention (DLP) and to meet other content standards in outgoing email. Predefined filters and custom policies can be used to detect sensitive data and block or encrypt email.

* DLP addon required for encryption functionality.
** Outbound filtering currently only available for Microsoft Exchange
