I'll assume you guys have mirrored PAIN and have looked in to NIAP?

From Wiki: "The National Information Assurance Partnership (NIAP) is a United States government initiative to meet the security testing needs of both information technology consumers and producers that is operated by the National Security Agency (NSA), and was originally a joint effort between NSA and the National Institute of Standards and Technology (NIST)."
