Safeguarding Sensitive Data in Microsoft 365 Copilot with Purview DLP (GA Release)

on
The challenge with sensitive data and access to Copilot Microsoft 365 Copilot empowers users with AI-driven assistance across Microsoft 365 apps, but it also raises concerns about accidental oversharing of sensitive information. In response, Microsoft has extended its Purview Data Loss Prevention (DLP) capabilities to Microsoft 365 Copilot, allowing organizations to enforce information protection policies within AI workflows. The DLP for Microsoft 365 Copilot has been in preview for some time, but Microsoft has now announced it is released for GA (General Availability). Among some of the interesting features are new features like alerting and policy simulation. Key details:  Rollout Timeline: As of June 2025, the rollout has begun. It should be completed worldwide by late July 2025. Scope: Initially, DLP for Copilot was available for Copilot Chat scenarios. By the time of GA this is expanding to Copilot in core Office apps (Word, Excel, PowerPoint) as well. Ensuring that DLP prote...

Microsoft 365 Copilot Chat - Pay As You Go

on

Here is an update that really caught my eye this week. Microsoft is introducing Microsoft 365 Copilot Chat (BizChat) as a Pay-As-You-Go (PayG) service. This option will be available starting late January 2025, with full availability by mid-February 2025.

Key Highlights:
  • Flexible Access: Organizations can offer Copilot on company data without requiring individual licenses. However, a license is still needed for Copilot within applications like Outlook, Teams, and PowerPoint.
  • Controlled Costs: The PayG service is disabled by default and only activates after billing setup in the Microsoft 365 admin center, preventing unexpected expenses.
  • Easy Setup: To enable PayG billing, navigate to "Settings -> Org Settings" in the Microsoft 365 Admin Center. An Azure subscription and a dedicated Resource Group are required.

The PayG model offers a low-cost entry point to Microsoft 365 Copilot Chat, ideal for testing or intermittent usage. It provides flexibility to scale usage based on actual needs, avoiding the cost of unused licenses. However, it's crucial to monitor usage to prevent unexpected costs, as PayG can be more expensive than fixed licenses if not managed properly. For consistent, high usage, a fixed license per seat may be more cost-effective.

Fixed licenses offer predictable costs and additional features, making budgeting simpler. While PayG is limited to the Chat application, it’s a great way to introduce Copilot into your organization.

It is going to be interesting to see if organizations embrace this new model, and how it potentially can drive the usage of generative AI even further within companies.
