Company A always delivers total support in their materials deposition processes, and to be able to ensure that its customers continue to receive this high-quality support and service, it is necessary for Company A employees to have solid, uninterrupted means of communication, company-wide as well as with customers. Before 2005, Company A struggled with keeping email, one of its most important communication channels, flowing due to increasing amounts of unsolicited email hitting employees’ inboxes.

The legacy email filtering system Company A relied on was not stopping the spam from bombarding the company’s 800+ globally based email users who were located both in the field and 18 satellite offices. According to their IT security analyst, an estimated 20% of spam was getting through to its email users.

Spam Wastes Company’s A Time and Resources

Originally Company’s A MIS department began filtering email to ensure compliance, however, spam had become a primary issue. Previously, the MIS department would check its email filter periodically. However, this became nearly a full-time task, which included the risk that a genuine email, possibly an order from a long-standing customer, could be inadvertently deleted.

Finding a New, Reliable, Email Security Solution

Plagued by complaints from frustrated users who had to wade through massive amounts of spam, as well as those who had lost important emails, the main task was to find a more capable email security solution that could also provide protection against ever-present threats. Compliance was also paramount to Company A. The MIS department and Company A management were keen to stop inappropriate content from entering the company and they also needed to ensure that employees did not send email that might include inappropriate language or content to customers.

Barracuda Spam Firewall Stops Spam and Helps Ensure Compliance

After researching and evaluating several solutions, the IT manager spoke with a Hertfordshire-based IT company that recommended a Barracuda Spam Firewall and he was pleased that Barracuda Networks offers a 30-day free evaluation unit.

“It was difficult to test a potential product fully as it required (simulating real email traffic) using large volumes of unsolicited email to test effectively,” says the IT manager. “This is why a 30-day evaluation from Barracuda Networks was put straight into a live environment, not something we would do lightly, but the benefits were immediately obvious.”

Company A was so impressed with the results of the trial and the Barracuda Spam Firewall’s affordable price that the company purchased four Barracuda Spam Firewall models: Company A placed two Barracuda Spam Firewalls at each mail gateway, one at their UK headquarters and another at its office in Germany, in a clustered environment for redundancy. This allowed the units to share one rule base and users only needed to access one site to check their own quarantine areas.

Company A also purchased two Barracuda Spam Firewall 300s for outbound email filtering in both the UK and German offices. Internal mail servers direct email to the Barracuda Spam Firewalls in outbound mode via a fake MX zone. This ensures that the most available Barracuda Spam Firewall receives the email to send out, which reduces the risk of downtime due to connectivity issues.

The Bottom Line

“We went from receiving approximately 20% of the spam email sent to us to about 2%, with extremely low false positives – those numbers speak for themselves,” reveals Company A. According to them, between January 2005 and October 2007, Company A received 4.3 million emails of which only 850,000 were allowed as legitimate email.

Overall, the Barracuda Spam Firewall has saved Company A an immeasurable amount of time and resources. “Previously we had someone virtually full-time, manually sift through emails to determine what was spam and what was not,” recalls the IT Management Team. “The time this person spent doing a miserable job is now spent doing something more interesting and constructive.
