Seamless security alerts with Sophos and Copilot Studio via Power Automate
A new integration lets users retrieve Sophos Central security alerts by simply typing a request into a Copilot Studio chat—no dashboards or manual API calls required. The setup uses Power Automate to bridge the agent and Sophos API, delivering formatted responses directly in the conversation.
How the pieces fit together
The system relies on three components working in sequence. A Copilot Studio agent receives the user’s query, a Power Automate flow handles authentication and data retrieval via the Sophos API, and the response is passed back to the agent for presentation. Keeping API logic in the flow simplifies the agent and avoids exposing credentials.
The flow, named Sophos - Get Alerts, is built in a solution called Sophos Integration. It starts with an HTTP trigger when called by Copilot Studio, then initializes four variables: the Sophos Client ID, Client Secret, Tenant ID, and the API host URL based on region. An OAuth token is requested using client credentials, and the access token is parsed from the response. The token is then used in a GET request to Sophos Central’s alerts endpoint, with the Tenant ID included in a dedicated header.
Managing credentials and avoiding pitfalls
Credentials are currently stored as restricted flow-scoped variables, with plans to migrate to Azure Key Vault when available. Alternative options like Dataverse environment variables were considered but introduced unnecessary complexity. During debugging, temporarily disabling secure input/output on HTTP actions helped inspect request and response bodies, though these were re-enabled once troubleshooting was complete.
The most time-consuming issues involved misplaced headers and broken variable references after renaming actions. A header’s Content-Type was accidentally placed in the Value column instead of the Key column, leading to a vague rejection from Sophos. Renaming an action without updating downstream references also caused runtime errors. These lessons highlight the importance of careful configuration and validation in low-code automation.
