Artificial intelligence is only as trustworthy as the controls that govern it. For U.S. federal agencies, that means FedRAMP - the government’s standardized approach to security assessment, authorization, and continuous monitoring of cloud services under FISMA. FedRAMP is not a paperwork exercise; it’s a continuous-monitoring operating model that aligns cloud services to NIST SP 800-53 controls and forces rigor around identity, logging, data protection, configuration, and supply chain.

Below is a practical guide to using Microsoft AI capabilities (Copilot for Microsoft 365, Copilot Studio, and Azure AI Foundry) in a way that keeps you aligned to FedRAMP requirements, plus the Microsoft security and compliance tools that help you sustain authorization.

TL;DR - The Bottom Line

  • Run AI where FedRAMP applies. Choose the right Microsoft government cloud and services that are in scope for FedRAMP (Moderate/High) and, where needed, DoD IL levels. Microsoft publishes which services are covered across Azure, Azure Government, and Microsoft 365.
  • Use Microsoft’s government-ready AI stack.
    • Azure OpenAI Service is approved within FedRAMP High for Azure for U.S. Government and also approved for DoD IL4/IL5—the cornerstone for compliant LLM workloads. It’s worth noting that Azure OpenAI Service is available in the Azure IL6 boundary. IL6 leverages the DoD Cloud Computing Security Requirements Guide (SRG), managed by DISA.
    • Copilot Studio (US Gov) runs in a FedRAMP High-compliant GCC environment, letting you build/extend copilots with government data boundaries.
    • Azure AI Foundry is available in Azure Government, giving agencies a sovereign environment to design, evaluate, and ship AI apps and agents.
  • Know where Copilot for Microsoft 365 stands. Copilot is available as an add-on for GCC today; GCC High remains in development with GA targeted later in 2025, pending government authorization.
  • Operationalize compliance with Defender for Cloud, Purview, and Defender for Cloud Apps (CASB) to continuously map to FedRAMP controls, manage data risks, and govern SaaS and OAuth apps.

Mapping Microsoft AI to FedRAMP: What “Good” Looks Like

Azure AI Foundry + Azure OpenAI
  • Where it runs: Azure AI Foundry is available in Azure Government, ensuring prompt flows, data connections, and agent orchestration remain inside a sovereign environment aligned with FedRAMP High and DoD IL4/IL5 requirements. For classified workloads, the Azure OpenAI Service is also available within the DoD IL6 boundary, adhering to the DoD Cloud Computing Security Requirements Guide (SRG) managed by DISA.
  • The model service: Azure OpenAI inside Azure Government is FedRAMP High authorized and certified for DoD IL4/IL5, providing agencies with compliant access to LLMs. The IL6 offering supports classified workloads with alignment to control families such as AC (Access Control), SC (System & Communications Protection), and AU (Audit & Accountability).
  • Controls: 
    • Configuration Management (CM): Azure Policy can enforce encryption at rest (SC-12, SC-13), use of customer-managed keys (SC-28), and private networking (SC-7, SC-31).
    • Audit & Accountability (AU): Defender for Cloud ensures continuous monitoring and centralized logging, supporting AU-2 (Auditable Events), AU-6 (Audit Analysis), and AU-12 (Audit Record Generation).
    • Access Control (AC): Entra ID with Conditional Access and Privileged Identity Management enforces MFA and least-privilege access (AC-2, AC-3, AC-5, IA-2).
    • System & Information Integrity (SI): Defender for Cloud detects anomalous behavior, helping satisfy SI-4 (System Monitoring) and SI-7 (Software Integrity Checks).
Copilot for Microsoft 365

GCC: Available today as an add-on for Microsoft 365 GCC tenants.
GCC High/DoD: The tentative GA is targeted for late 2025, pending government authorization.
Controls:

  • Data Protection (SC, MP): Microsoft Purview sensitivity labels and DLP enforce classification and protection for sensitive content (SC-28, MP-5, MP-6).
  • Access Control (AC): Conditional Access policies and MFA enforce account security (AC-2, AC-17, IA-2).
  • Audit & Accountability (AU): Unified Audit Logs and Insider Risk Management map to AU-6 (Audit Review/Analysis) and AU-8 (Time Stamps).
  • Identification & Authentication (IA): Strong authentication methods (PIV/CAC or FIDO2) meet IA-2 and IA-5 requirements.
  • System & Communications Protection (SC): Exchange Online Protection and Information Barriers provide boundary and data flow control (SC-7, SC-31).
Copilot Studio for US Government
  • Environment: Runs in GCC with FedRAMP High compliance, enabling safe bot/copilot authoring.
  • Controls: Apply DLP policies for connectors, restrict cross-tenant flows, and use Managed Environments for governance.
    • Data Loss Prevention (DLP): Policies restrict which connectors can access sensitive data, satisfying AC-4 (Information Flow Enforcement) and SC-7 (Boundary Protection).
    • Configuration Management (CM): Managed Environments enforce change management and ALM practices, mapping to CM-2 (Baseline Configuration) and CM-6 (Configuration Settings).
    • Access Control (AC): Role-based access and least-privilege assignments ensure proper segregation of duties (AC-5, AC-6).
    • Audit & Accountability (AU): Copilot Studio activity logs integrate with Microsoft Purview and SIEM tools, satisfying AU-2 (Auditable Events) and AU-12 (Audit Generation).
    • System & Integrity (SI): Secure connector validation and monitoring help ensure data integrity across services (SI-4, SI-7)

Getting Practical: The Control Plane for Staying Compliant

Defender for Cloud

Maps Azure resources to FedRAMP High with built-in initiatives, posture visibility, and compliance dashboards—essential for continuous monitoring.

Purview

  • Compliance Manager: Provides FedRAMP templates, improvement actions, and evidence exports.
  • Data lifecycle: Auto-labeling, DLP, and retention policies keep AI training data and prompts compliant.

Defender for Cloud Apps (CASB)

  • Governs SaaS and shadow AI usage, provides OAuth app governance, and enforces access/session policies.
  • Aids compliance by ensuring only vetted AI and SaaS apps are in use.

A FedRAMP-Aligned AI Architecture

  1. Identity: Entra ID + Conditional Access, CAC/PIV/HSPD12 etc.
  2. Data Boundary: Azure Government with Defender for Cloud FedRAMP High initiative.
  3. Model Layer: Azure AI Foundry + Azure OpenAI (Gov).
  4. Productivity AI: Copilot for Microsoft 365 (GCC today; GCC High coming).
  5. Governance: CASB for SaaS/OAuth apps.
  6. Monitoring: Purview Compliance Manager + Defender for Cloud dashboards for continuous authorization evidence.

Programmatic Steps Toward ATO

  1. Select FedRAMP-covered services.
  2. Stand up Azure Gov landing zones with FedRAMP initiatives.
  3. Gather control evidence with Purview + Defender for Cloud.
  4. Harden data with Purview DLP/labels.
  5. Govern SaaS/AI usage with CASB.
  6. Continuously monitor and export reports for auditors.
