Microsoft Copilot Governance Framework

The risks specific to generative AI in the enterprise

Microsoft 365 Copilot isn't just one more productivity tool. It's a system that reaches every piece of content the user is entitled to see, generates content presented as factual, and can influence or even make decisions. Three dimensions of risk come on top of what traditional tools carry:

• Oversharing risk: Copilot surfaces everything a user can access to that user - including content that's been overshared for years and that no one remembers.
• Hallucination risk: Copilot can generate factually incorrect information with a high degree of apparent confidence. Without human validation, the errors spread.
• Regulatory risk: Law 25 section 12.1 imposes specific obligations on automated decisions. Europe's GDPR (and the AI Act) adds further constraints when you operate internationally.

The cost of no governance

Three scenarios we saw in 2024-2025 at companies that had no governance framework in place:

Scenario 1: an employee asks Copilot for a recap of the HR projects underway. The answer is thorough and detailed - and it includes a colleague's ongoing salary negotiations, exposed through a SharePoint sharing mistake dating back to 2022. No malicious intent, but a major confidentiality incident to deal with.

Scenario 2: a sales rep uses Copilot to draft a proposal. The final document cites the wrong client references - Copilot had blended two similar cases together. The proposal goes out to the client. The factual error surfaces at signing.

Scenario 3: an HR team member uses Copilot to screen 200 applications. No human review at any point. A candidate later files a complaint citing section 12.1 - and the organization has no record of the process and no documented review mechanism.

Pillar 1 - A formal usage policy

A short document (2-4 pages), approved by leadership and shared with every Copilot user. It spells out: what Copilot may be used for, what it must not be used for, who may configure and administer it, how to report an incident, and who the accountable sponsor is.

This policy is attached to the employment contract, or to an addendum, for Copilot users. It's reviewed annually.

Pillar 2 - A practical user charter

Shorter (1 page), plain-language, handed out and signed when Copilot is activated. It turns the policy into concrete rules a user can understand and follow.

See the charter template provided in the appendix of this white paper.

Pillar 3 - Technical controls in Purview

Paper governance isn't enough. Microsoft Purview provides the technical mechanisms to enforce the policy:

• Sensitivity labels: labelling and encrypting sensitive documents, with filtering by Copilot.
• Data Loss Prevention (DLP): policies that block certain data types from being included in Copilot responses.
• Insider Risk Management: detecting abnormal Copilot usage (volume, sensitive topics, exfiltration).
• Copilot audit logs: traceability of every prompt and every response, retained 1 year or more.
• Retention policies: how long Copilot conversations are kept.

Pillar 4 - A use-case approval process

For high-risk uses (decisions about people, processing of highly sensitive data, automation of business processes), an up-front approval process is essential.

A monthly AI committee: representatives from the CISO office, the privacy officer (Law 25), legal, the business, and IT. It reviews every new use case proposed and decides: approve, approve with conditions, or decline.

Pillar 5 - Training and awareness

The initial Copilot training (90 minutes) covers: a walkthrough of the use cases, the usage charter, best practices (validation, citing sources, caution with sensitive data), and incident reporting.

Ongoing awareness: a monthly "use case of the month" email, a short quarterly quiz, internal lessons learned, and an annual refresh of the training.

Pillar 6 - Measurement and continuous improvement

A quarterly dashboard shared with the leadership committee:

• Adoption (% of active users, volume of interactions).
• Quality (user satisfaction, rate of reported errors, incidents).
• Compliance (Purview audits, DLP policies triggered, Law 25 requests handled).
• Use cases approved vs. declined (tracked by the AI committee).
• Relevant Microsoft developments (new Copilot capabilities, new Purview features).
