Apple, on a webpage I’ve never seen before, about a standard I didn’t know was a thing until today:
An internationally approved set of security standards which provides a clear and reliable evaluation of the security capabilities of Information Technology products. By providing an independent assessment of products and the ability to meet security standards, Common Criteria gives customers more confidence in the security of Information Technology products and leads to more informed decisions.
Security-conscious customers, such as the U.S. Federal Government, are requiring Common Criteria certification as a determining factor in purchasing decisions. Since the requirements for certification are clearly established, vendors can target very specific security needs while providing broad product offerings.
