NSA OIG investigates a wide variety of allegations of waste, fraud, abuse, and misconduct involving NSA/CSS programs, operations, and personnel. The OIG initiates investigations based upon information from a variety of sources, including complaints made to the OIG Hotline; information uncovered during its inspections, audits, and reviews; and referrals from other Agency organizations. Complaints can be made to the OIG Hotline online, by email, regular mail, telephone, or in person. Individuals can do so anonymously or identify themselves but indicate that they wish to maintain their confidentiality.

Whistleblowers play a critical role in identifying instances of waste, fraud, and abuse in U.S. government operations. It is critical that whistleblowers feel free to provide information without fear of retaliation. The NSA OIG Hotline provides a mechanism for whistleblowers to make protected communications, and the Investigations Division carefully examines all credible claims of whistleblower reprisal.
