Butler University Deploys Innovative Hybrid Solution From Proofpoint to Stop Spam and Viruses

Hybrid Deployment of Physical and Virtual Appliances Provides Cost-Effective Way for University to Manage High Volume of Inbound Email, Stopping Nearly a Million Spam Messages a Day

SUNNYVALE, CA--(Marketwire - August 11, 2008) - Proofpoint, Inc., the leading provider of unified email security, archiving and data loss prevention solutions, today announced that Butler University has deployed the Proofpoint Messaging Security Gateway™ appliance and the Proofpoint Messaging Security Gateway - Virtual Edition for complete anti-spam and anti-virus protection. This "hybrid" approach of combining physical and virtual appliances can scale indefinitely to support millions of inbound and outbound email messages per day and provides the university with 100 percent system redundancy.

Since 2004, Butler University has used the Proofpoint Messaging Security Gateway appliance to defend against inbound messaging threats such as spam, viruses and denial-of-service attacks. The university originally selected Proofpoint based on the appliance's ease-of-use, high rate of anti-spam effectiveness, Web-based management interface and flexible end-user controls.

"When we evaluated Proofpoint four years ago, it was obvious that the Proofpoint Messaging Security Gateway required very little customization or ongoing administration in order to accurately block spam," said Nathan Partenheimer, Systems Administrator, Information Resources department at Butler University. "Proofpoint has performed exactly as we've needed, eliminating all types of spam messages while also eliminating the need for a full-time email / spam administrator."

Like most large organizations, Butler University has seen overall email volumes rise significantly over the years. Today the university averages one million inbound messages per day, 90 percent of which are spam. As the university's email volumes have grown, its Proofpoint deployment has also expanded.

Most recently, Butler University has taken advantage of Proofpoint's hybrid deployment options, adding Proofpoint Messaging Security Gateway - Virtual Edition appliances to create a mixed hardware / virtual environment. The university uses hardware appliances to scan inbound mail, while virtual appliances, which leverage the university's existing VMware infrastructure, scan the outbound messaging stream to ensure that sent messages are also free from spam content, viruses and other malicious code. This prevents students from propagating spam and viruses and enables the university to detect botnet infections among its user base.

"The Proofpoint virtual appliance was extremely easy to deploy and provides the same high-level of spam and virus protection as Proofpoint's hardware appliance," said Partenheimer. "With the Proofpoint virtual appliance in place we can easily and cost-effectively scale to manage spikes in inbound or outbound email, as new virtual appliances can be provisioned in minutes to address our changing email requirements."

All policy management and administration tasks for both the Proofpoint hardware and virtual appliance are controlled via Proofpoint's single Web-based administration console, resulting in zero-overhead administration for Butler University. The university also takes advantage of Proofpoint's end-user digest feature, allowing students, faculty and administration to personally manage email quarantines and adjust individual levels of anti-spam protection as desired.

"Proofpoint provides organizations with the most flexible messaging security solutions on the market, with all features -- including anti-spam, anti-virus, multi-protocol content security, policy-based encryption and reporting features -- able to be deployed in nearly any configuration," said Sandra Vaughan, senior vice president of products and marketing for Proofpoint. "Proofpoint also offers unique hybrid deployment options that allow customers to combine Proofpoint's hardware or software with Proofpoint's virtual appliance or Proofpoint on Demand to leverage the best aspects of virtual, hosted and on-premise solutions."
