Microsoft Purview Information Protection also called as Microsoft Information Protection (MIP) helps discover, classify, and protect sensitive information wherever it exists or travels.
Microsoft Purview compliance portal, also called as Azure Information Protection (AIP) is a cloud-based solution. To integrate Trellix DLP Network with Microsoft Information Protection (MIP) you must have access to both Microsoft Purview Information Protection (called as MIP) and Microsoft Purview compliance portal (called as AIP). Integration of Trellix DLP Network with AIP allows you to use the functionalities of AIP including file encryption and data protection:
Allows you to integrate Trellix DLP Network with AIP to act as a decryption proxy client (MIP client) and use valid AIP credentials to decrypt AIP protected files. Trellix DLP Network decrypt all data submitted for data protection analysis.
Users can apply sensitivity labels to the M365 documents, PDFs, text files, email, and web uploads to comply with the company policy. You can configure sensitivity labels in AIP for different data protection policies either with encryption or without encryption.
You can use Labelinfo in MSIP classifications to support reading MIP label information or metadata in co-authored or auto-save enabled documents.
