Company Description

Centripetal is bringing to market advanced network hardware and software products to implement trusted networks. We believe current cyber security methods and techniques will not be effective against the future threat. Today cyber countermeasures consist of point solutions that require large investments of time, attention and manpower for every vulnerable organization. As the target base expands, this approach to security is clearly unsustainable. We need a new approach to the problem. Instead of point solutions, we believe that Cyber Security needs to be built into the very infrastructure of the Internet.
