AFC-FRP-CDS MUST — Criticality Designators

FedRAMP MUST convey the criticality of the message in the subject line, IF the message requires an elevated reaction, using one of the following designators:

Checklist items:

• Emergency: There is a potential incident or crisis such that FedRAMP requires an extremely urgent reaction; emergency messages will contain aggressive timeframes for reaction and failure to meet these timeframes will result in corrective action.
• Emergency Test: FedRAMP requires an extremely urgent reaction to confirm the functionality and effectiveness of the FedRAMP Security Inbox; emergency test messages will contain aggressive timeframes for reaction and failure to meet these timeframes will result in corrective action.
• Important: There is an important issue that FedRAMP requires the cloud service provider to address; important messages will contain reasonable timeframes for reaction and failure to meet these timeframes may result in corrective action.

Terms: FedRAMP Security Inbox, Incident, Provider

Affects: FedRAMP

Note: Messages sent by FedRAMP without one of these designators are considered general communications and do not require an elevated reaction; these may be resolved in the normal course of business by the cloud service provider.

Recent update: 2026-06-24 — Official launch of the FedRAMP Consolidated Rules for 2026.

Terms: Debilitating Customer Effect, FedRAMP Certified, Provider

Terms: Provider

Affects: FedRAMP

Note: Anyone at GSA can send email from @fedramp.gov or @gsa.gov - FedRAMP team members will typically have “FedRAMP” or “F20B” in their name but this is not universal or enforceable. The nature of government enterprise IT services makes it difficult for FedRAMP to isolate FedRAMP-specific team members with enforceable identifiers.
