Because the Sentinel application has a real-time connection to the TippingPoint service, which updates its database at least every two hours, it has the latest information to secure the network. And because it only captures DNS traffic instead of the full flow of Web-browsing data, it can work efficiently, Sanchez said.
HP is actively working on a commercial version of Sentinel and expects one to be available this year, Sanchez said. HBO is an early release customer, and the software is being prototyped and tested on that company's network, he said. HP has also been talking to several telecommunications carriers about using Sentinel on their backbone networks, Sanchez said.
Sentinel is complementary to the current TippingPoint offering but its scalability is a key benefit to carriers and enterprises, according to HP.
"In order to get the kind of coverage and scale that you get with software-defined networking, what people would have to do today is deploy a lot of appliances throughout their network. And let's face it, not many people are willing to do that unless they're very, very paranoid," Sanchez said.
