Microsoft Copilot Studio empowers organisations to create custom AI agents tailored to internal workflows—ranging from HR onboarding to finance process automation. But as these agents increasingly connect with sensitive data sources and business systems, Australian enterprises must address one critical area from day one: cybersecurity.
Copilot Studio brings powerful capabilities—but it also introduces new vectors of exposure. Without clear safeguards, even well-intentioned AI agents can inadvertently surface confidential information, violate governance rules, or create access loopholes. Below, we outline the seven most important cybersecurity considerations to guide a safe and compliant Copilot Studio rollout.
1. Design for Principle of Least Privilege (PoLP)
Every agent you build should operate with the minimum permissions required. Assign scoped access using Microsoft Entra ID (formerly Azure AD), limiting each agent’s access to only the connectors, environments, and data tables they truly need. This reduces the risk of overreach or unintended data exposure—especially important in regulated industries like finance and healthcare.
2. Use Dedicated Environments for Dev, Test, and Production
Copilot Studio lets you create separate environments in Power Platform. Leverage this to isolate development from live environments, apply RBAC to each stage, and reduce the blast radius of errors or vulnerabilities. For production deployments, enable environment-level DLP policies that control which connectors agents can use—and monitor changes proactively.
3. Control Access to Third-Party Data & APIs
While Copilot Studio supports connecting to external data via custom connectors, every integration must be vetted. Document and assess each external API against your internal risk posture. Use OAuth 2.0 with scopes and token expiry, enforce throttling, and inspect how third parties handle encryption, logging, and data storage.
4. Configure Secure Logging & Monitoring
Copilot agents may surface responses drawn from internal systems—making observability essential. Implement centralized logging via Microsoft Dataverse and monitor agent behavior using tools like Microsoft Defender for Cloud Apps or Azure Monitor. Track prompts, responses, and data retrieval activities for audit and forensics.
5. Use Prompt Filtering and Content Moderation
Agents are only as safe as their prompts. To reduce prompt injection risks or misuse, validate user input and use pre-approved phrases or guardrails within conversational flows. Avoid exposing sensitive variables (e.g., authentication tokens, PII) in user-accessible messages. Where feasible, use Microsoft’s built-in content moderation features in Copilot Studio or layer with Azure Content Safety APIs.
6. Encrypt Everything—In Transit and At Rest
All data moving between Copilot Studio agents and connected services should be encrypted using TLS 1.2+ with strong cipher suites. In addition, data stored in Dataverse or linked services must be encrypted at rest using managed keys. If your enterprise requires customer-managed keys (CMKs), use Azure Key Vault integration.
7. Enforce Governance with Copilot Studio Policies
Develop a Copilot Studio-specific governance policy. This should include:
- Agent review workflows and change control
- Security training for makers and low-code developers
- Version control, release approvals, and rollback strategies
- Ongoing vulnerability scanning of connectors and dependencies
Microsoft recommends maintaining a governance board or Centre of Excellence (CoE) for Power Platform and Copilot Studio combined.
