US regulators mandate on-site review for sensitive bank data
US banking agencies will now review highly sensitive information on-site rather than downloading it, a shift aimed at reducing cyber risks that will alter how executives prepare for regulatory exams.
The Federal Reserve, Federal Deposit Insurance Corporation, and Office of the Comptroller of the Currency have jointly established new security procedures for handling highly sensitive information during bank examinations. Going forward, examiners will review sensitive materials on-site at supervised institutions rather than transferring the data onto regulatory agency systems.
Changes to examination logistics
The July 16 statement details a coordinated approach across the three agencies to identify precisely which documents qualify as highly sensitive. For bank executives and compliance teams, this mandates a fundamental shift in how they prepare for regulatory oversight. Lenders must now allocate secure, localized environments for examiners to conduct their work, ending the standard practice of securely transmitting this data to government servers.
Balancing access and cybersecurity
By keeping highly sensitive data on bank premises, the regulators aim to mitigate the cybersecurity vulnerabilities associated with data in transit and at rest on external networks. The agencies emphasized that this procedural change is designed to protect confidential supervisory information against unauthorized access or disclosure. Crucially, the agencies stated these enhanced procedures will not impede their work, noting they will ensure access to such information at all times during an examination.
A 72-hour breach notification standard
Alongside the on-site mandate, the agencies introduced a strict disclosure timeline for any potential or confirmed material data breach involving confidential supervisory information. Regulators are now explicitly committed to notifying affected banks as soon as practicable. This notification must occur no later than 72 hours after discovery, unless specific legal restrictions prevent it.
Impact on institutional risk
This 72-hour requirement establishes a new level of accountability for federal regulators regarding data stewardship. For market professionals and bank risk officers, it removes historical uncertainty about how and when regulators would disclose a compromise of confidential data. This clarity is particularly relevant as financial institutions face increasing pressure to map out third-party and regulatory counterparty risks. Institutions can now incorporate this guaranteed 72-hour warning window into their own incident response frameworks, allowing for faster internal assessments if federal systems are ever breached during an exam.
