Central IT Services provides the UNIL community with an institutional version of Microsoft 365 Copilot Chat \u201cProtected\u201d<\/strong>, activated under the CASA-EES contract. It is currently the only generative language model<\/strong> made available to the entire UNIL community because the negotiated contractual terms meet legal compliance requirements and UNIL security standards. Other solutions could be considered in the future, provided they meet similar conditions and appear on the list established by the DPO.<\/p>\n\n

What You Can Do with Microsoft 365 Copilot Chat<\/h4>\n\n

Microsoft 365 Copilot Chat, like other Microsoft 365 tools deployed at UNIL (OneDrive, Teams, Outlook), has been validated for temporary use<\/strong> as part of the collaborative tools made available. It can therefore be used to process private documents or content subject to official secrecy, under the same contractual security conditions.<\/p>\n\n

\u26a0\ufe0f Warning:<\/strong> the Copilot Chat interface does not have a button to enable or disable web search<\/strong>. Depending on the wording of your request (e.g., “find me the latest work by…” or “what is the news on…”), Copilot may automatically trigger a search via Bing<\/strong>, resulting in data transmission outside the protected environment<\/strong>. Avoid any request likely to trigger an online search<\/strong> when working with private documents or those subject to official secrecy (see the “Use the UNIL agent \ud83d\udcd8 [Secure]” section below).<\/p>\n\n

Use the UNIL \ud83d\udcd8 [S\u00e9curis\u00e9] agent<\/h4>\n\n

To avoid any risk of accidental external search, a dedicated UNIL \ud83d\udcd8 [Secure] <\/strong>agent is available in Copilot Chat. This agent has been configured so that web search (Bing) is disabled by default<\/strong>, ensuring that your data remains within the protected Microsoft 365 environment. It is recommended to prioritize this agent for processing private documents or content subject to official secrecy.<\/p>\n\n

Sensitive Data: Do Not Enter<\/h4>\n\n

Certaines donn\u00e9es sensibles au sens de la l\u00e9gislation suisse<\/strong>, comme des dossiers m\u00e9dicaux, des informations de sant\u00e9 identifiantes ou des donn\u00e9es RH confidentielles, ne doivent pas \u00eatre saisies dans Microsoft Copilot<\/strong>. Leur traitement requiert des syst\u00e8mes sp\u00e9cifiquement approuv\u00e9s par l’UNIL comme des\u00a0mod\u00e8les locaux d\u00e9ploy\u00e9s sur les infrastructures du Centre informatique ou sur des ordinateurs personnels<\/strong> (voir tutoriel<\/a>), sans recours \u00e0 des services cloud.<\/p>\n\n
