Significant Change Notification under Consolidated Rules 2026

Significant Change Notices: Notify, Do Not Ask

Key takeaway: Under CR26, providers notify necessary parties of a significant change instead of asking for approval first. FedRAMP does not require agency approval of a change, and each notice names the provider's own internal approver. What a provider owes depends on the type of change: routine recurring changes need no notice, adaptive changes are notified within 10 business days after they finish, and transformative changes are announced at least 30 business days before they start. The ruleset applies to Rev5 providers from January 1, 2027, with a grace period to June 1, 2027.


See What Is FedRAMP 20x, the 20x roadmap, OSCAL for FedRAMP and NISTcompliance.ai for the tooling that keeps notices and evidence in one record.

Regulatory comparison

From request to notification

Under Rev5, providers submitted a Significant Change Request and waited for approval. CR26 replaces that gate with a notice.

Operating modelPrior approval. Providers requested and waited.Notification. Providers notify and record their own approver.
Who decidesThe authorizing official approved or rejected the request.The provider decides and notifies. FedRAMP may require delays or advance approval only under a Corrective Action Plan (SCN-FRP-CAP).
TimingThe change waited on the approval.By change type, from no notice at all to 30 business days of advance notice.
FormatStandalone request documents.Notices in human-readable and JSON formats (SCN-CSO-HRM), recorded in FedRAMP Certification Data.
AssessorReviewed the request before the change.Third-party assessor review should be engaged before a transformative change when human validation is needed (SCN-TRF-TPR).

The notification threshold is the same idea as the old request threshold. What changes is the gate: providers no longer wait for approval, and the notice carries the evidence that the posture is maintained.

Operational triggers

How to classify a change

The type of change sets the notice a provider owes. Examples below are the ones FedRAMP gives.

Routine recurring

No formal notice

Routine work by staff during normal duties, with no major availability impact and no executive approval. FedRAMP says providers should not send formal notices for these (SCN-RTR-NNR).

Provisioning capacity for elasticity
Generating or refreshing API or access tokens
Routine patching of devices, operating systems, software or libraries
Updating security service or endpoint signatures
Adaptive

Notify within 10 business days after

Minimal changes to security plans or procedures, with some planning and verification of functionality and secure configuration afterward.

Updates with known breaking changes
Changing a cryptographic module to one with the same standards and characteristics
Replacing a like-for-like component where some procedures change
Adding models to an approved AI service without exposing federal customer data to new services
Transformative

Plans 30 and 10 business days before

Changes the service risk profile or customer responsibilities, needs significant new design and testing, or needs extensive updates to assessments and documentation.

Adding, removing or replacing a critical third-party service
Raising the security categorization of a service that handles federal customer data
Replacing underlying management planes
Migrating a datacenter across boundaries
Adding an AI capability that affects federal customer data differently
Emergency

Proceed, then notify and assess

During an emergency or incident a provider may make significant changes without following the SCN rules in advance. It must still follow its procedures, notify necessary parties, provide SCN materials afterward and complete an assessment (SCN-CSO-EMG).

Providers evaluate every potential change in order: is it a significant change, does it change the certification class, is it routine recurring, is it transformative, and otherwise it is adaptive. A change of certification class needs a new assessment, not a notice (SCN-CSO-EVA).

Notice timing

What to send, and when

Business days are counted by the provider. The rules for adaptive and transformative changes are the same for 20x and Rev5.

Notice timing and content by rule
RuleWhenWhat to send
SCN-ADP-NTFAdaptiveWithin 10 business days after finishingNotice to all necessary parties, with a summary of new risks or vulnerabilities if applicable.

SCN-CSO-EMGEmergencyDuring the emergency or incidentNotify necessary parties and provide SCN materials retroactively, then complete an assessment.
Effective dates

When the SCN ruleset applies

For 20x certifications it applies from July 4, 2026 to obtain certification and from January 1, 2027 to maintain it, and the grace period ends at the first independent assessment started after January 1, 2027. For Rev5 certifications it applies from January 1, 2027, with a grace period to June 1, 2027. A provider must adopt the ruleset by its grace date or FedRAMP Certification will be revoked.

How Cybertorch and NISTcompliance.ai support the notice lifecycle

Cybertorch generates validation evidence as a by-product of SOC operations. NISTcompliance.ai organizes that evidence into the notice, the SSP update and the POA&M.

Inheritance shrinks scope

Inherited controls stay inside Cybertorch's boundary, so your own change evaluation centers on the components you own and configure. Your inheritance responsibilities are confirmed in your Cybertorch responsibility matrix.

Evidence from monitoring

Cybertorch's continuous monitoring supplies the verification evidence a notice points to, so the notice and the evidence come from the same operating record.

SSP and POA&M upkeep

In the NISTcompliance.ai continuous monitoring platform, the SSP and POA&M stay current and the affected controls, evidence and impact analysis are organized so the notice record is complete.

One change, several frameworks

The same change updates CMMC Level 2 and FISMA documentation alongside FedRAMP, from one evidence base.

Common questions about Significant Change Notices

What does SCN stand for?
Significant Change Notification, also called a Significant Change Notice. Under CR26 it replaces the Significant Change Request.
Is approval required before I make a change?
No. FedRAMP does not require agency approval, and the notice names the provider's own approver. FedRAMP may require delays or advance approval only under a formal Corrective Action Plan (SCN-FRP-CAP).
What is the difference between an SCN and an SCR?
An SCR was a request that waited for approval. An SCN is a notification, timed by the type of change, that carries the plan, the impact and the evidence.
What changes need a notice?
Adaptive and transformative changes. Routine recurring changes need none, and a change of certification class needs a new assessment instead.
What counts as a routine recurring change?
Routine work done by staff during normal duties with no major availability impact and no executive approval, such as provisioning capacity, refreshing tokens, routine patching, updating signatures, and shipping normal fixes in a regular development cycle.
When must I notify?
Adaptive: within 10 business days after finishing. Transformative: initial plans at least 30 business days before starting, final plans at least 10 business days before, a notice within 5 business days after finishing, and another within 5 business days after verification, assessment or validation.
What must a notice contain?
The FedRAMP ID, the assessor name if applicable, the related vulnerability if applicable, the change type and its categorization, a description, the reason, the customer impact, the plan and timeline, the impact analysis, and the approver's name and title.
Who is notified, and how?
All necessary parties, with updates recorded in FedRAMP Certification Data. Providers choose the delivery mechanism and document it in the certification package.
What if there is an emergency?
A provider may make the change without following the SCN rules in advance. It must still follow its procedures, notify necessary parties, provide the SCN materials afterward and complete an assessment.
When does SCN apply to me?
For 20x certifications, from July 4, 2026 to obtain and January 1, 2027 to maintain. For Rev5, from January 1, 2027, with a grace period to June 1, 2027.
How does Cybertorch affect my SCN burden?
Inherited controls stay inside Cybertorch's boundary, so your change evaluation centers on the components you own and configure. Your responsibility matrix defines exactly which changes are yours to evaluate.
