PRESS RELEASE

Feb 16, 2010 — San Francisco, CA -- OpenDNS, provider of the world's leading Internet navigation and security services that make networks safer, faster, smarter and more reliable, today introduced Block Page Bypass, a new feature of its industry-leading cloud-based Web content filtering service designed to deliver more granular filtering control and power in the most efficient way possible. The announcement is significant as it eliminates a final remaining hurdle for global enterprises, large school districts and other organizations with per-user filtering, per-department filtering or filter-override needs for making the switch to OpenDNS Enterprise.

The much-anticipated Block Page Bypass feature works by empowering the network administrator or OpenDNS Enterprise account manager to assign individuals permission to bypass network-wide blocks and access designated Web sites. This highly effective and efficient method of granting access on a per-user basis does not require proxying of all Web sites, which is a weakness among appliance-based filtering products and services as it generally slows down network speeds. In contrast, OpenDNS Enterprise works by proxying only sites being bypassed.

Block Page Bypass hits a sweet spot with organizations that have the simple need of providing uninhibited Internet access to management while limiting access for the rest of the company. Also for organizations needing to provide different levels of access to different departments " such as HR and marketing being allowed to visit social networks like Facebook.com, while restricting access for customer support " but that don't want to deploy and manage costly appliances to accomplish the straightforward task. Additionally, OpenDNS is seeing heightening demand from organizations looking to reduce costs enterprise-wide, and finding that OpenDNS Enterprise with Block Page Bypass meets all of their Web content filtering needs.

OpenDNS Enterprise was delivered in response to customer demand for a better performing and more cost-effective Web content filtering solution than what was previously available via a pricey appliance. OpenDNS Enterprise removes both the complexity and the cost of managing Web content filtering: the total cost of ownership for OpenDNS Enterprise is a small fraction of what hardware, services and fees for Websense and Blue Coat cost.

"Since the wildly successful launch of OpenDNS Enterprise late last year, we've heard growing demand for a function that allows customers to assign filtering preferences on a per-user basis. It became very clear that this was something we needed to deliver, but the standard way this is accomplished by appliance vendors like Websense and Blue Coat is completely inefficient. What we present proudly today is significantly more intelligent, and no less than what you've come to expect from OpenDNS," said David Ulevitch, CEO of OpenDNS. "I personally encourage any company still paying for Websense or Blue Coat to give OpenDNS Enterprise a good look now that one of the final remaining hurdles to switching has been removed."

Block Page Bypass is available immediately in OpenDNS Enterprise and will also be available in 2010 as an add-on to OpenDNS Deluxe. For pricing and full feature lists, please visit: http://www.opendns.com/start
