FedRAMP Security Inbox

The FedRAMP Security Inbox rules ensure FedRAMP can reliably contact the security and compliance staff responsible for every FedRAMP-authorized cloud service offering. These rules also set expectations for urgent communications, response time testing, and routing important messages separately from general support or customer service channels.


General Provider Responsibilities

These rules apply to providers with any type of FedRAMP Certification.

Maintain a FedRAMP Security Inbox

FSI-CSO-INB

Changelog:

  • 2026-05-04: Initial reset for the Consolidated Rules for 2026 Public Preview.

Providers MUST establish and maintain an email address to receive messages from FedRAMP; this inbox is a FedRAMP Security Inbox (FSI).


Be careful using a personal email tied to an individual for this inbox due to the significant risk to future communications after a change in personnel!


Notes:

  • Unless otherwise notified, FedRAMP will use the listed Security Email on the Marketplace for these notifications.
  • If a provider establishes a new inbox in reaction to this guidance that is different from the Security Email then they must follow the FSI-CSO-NOC rules to notify FedRAMP.
