Cryptography Research protects its core operations from outside attack by maintaining a secured local network that is not connected to the Internet at all. Employees who need to work with sensitive data have two computers on their desks — one to access the secure network, and a separate computer to access the Internet.[6]

In 2009, Frost & Sullivan awarded the company the World Smart Card Technology Leadership of the Year Award, noting that the company is "one of the highest-volume and highest-value technology licensors in the semiconductor industry" and that "more than 4 billion security chips are produced under its licenses every year".[7]
