Minimize Oversharing Risks
Oversharing can increase risk as Copilot accesses more data across your environment. This infographic shows how Microsoft Purview helps detect overshared content, apply policy recommendations, and protect sensitive files. Have a look at it to see how you can minimize oversharing risks.
How do I customize this PowerPoint infographic template for my brand?
You can treat this PowerPoint deck as a ready-made framework and then layer your brand on top of it:
1. **Set up brand look and feel in Slide Master**
- Open **View → Slide Master**.
- Update the **theme fonts** to your brand typefaces.
- Update the **theme colors** to your brand palette.
- Replace any **placeholder logos** in the master with your own logo.
2. **Customize highlighted areas**
- In the slides, look for **highlighted text or graphics**—these indicate where you should insert your own content.
- Replace the placeholder copy with your **brand-specific messaging**.
- Once updated, **remove the highlight** so the text matches the surrounding style.
3. **Adjust layout and typography**
- Resize headlines and body text so they fit the layout without crowding.
- Make sure line breaks, spacing, and alignment are consistent with your brand standards.
4. **Update visuals (optional)**
- You may **replace stock photography or icons** in the template with your own images or icon sets.
- Keep in mind: images and icons that ship with the template are **licensed only for use inside this template** and should not be reused or altered for other materials.
5. **Finalize and export**
- Remove any **off-slide instructions** and any remaining highlighting.
- Use **File → Export** and save the final version as a **PDF**.
- Name the file according to your internal naming convention and choose the appropriate storage location.
Following these steps lets you quickly reimagine the template as a branded infographic without rebuilding the design from scratch.
What are the risks of oversharing data with Microsoft 365 Copilot?
When you bring Microsoft 365 Copilot into your environment, it works with the files and permissions you already have in place. While Copilot **honors existing user permissions**, it can surface content that people technically have access to but don’t actually need for their role. That’s where oversharing risk comes in.
Key points to keep in mind:
- Many organizations are adopting Copilot as a **trusted generative AI solution** for working with sensitive data.
- At the same time, a meaningful share of **US workers upload sensitive data to public AI platforms** (the source text references this trend, even though the exact percentage isn’t specified).
- A large portion of **current generative AI projects include a security component**, and a notable share of **AI-related security incidents result in compromised data** (again, the template cites these trends without exact percentages).
Why this matters:
- If file permissions are too broad—such as **organization-wide access**—Copilot may surface documents to users who don’t truly need them.
- This can lead to **unnecessary exposure of sensitive information**, even if no one intentionally breaks the rules.
- Oversharing can complicate compliance, increase the impact of any future breach, and erode trust in AI tools.
In short, Copilot itself respects permissions, but if your underlying access model is too open, you may unintentionally reshape how widely sensitive content is discoverable inside your organization.
How can Microsoft Purview help us secure and govern Microsoft 365 Copilot?
Microsoft Purview is designed to give you visibility and control over how content is shared and accessed before and during your Microsoft 365 Copilot rollout.
Here’s how it helps:
1. **Detect oversharing risks**
- Purview provides **enhanced visibility** into files that are broadly shared, including those with **organization-wide permissions**.
- It helps you **identify overshared content** so you can see where sensitive information might be exposed more widely than intended.
2. **Get actionable policy recommendations**
- Based on what it finds, Purview offers **policy recommendations** to tighten access.
- These recommendations help you **restrict broad access**, adjust sharing settings, and align permissions with your security and compliance standards.
3. **Remediate and enforce access controls**
- You can **remediate oversharing permissions** directly—removing unnecessary access and narrowing who can see what.
- Access controls help ensure people have **the right level of file access for their role**, not more.
4. **Control how Copilot interacts with sensitive files**
- Purview can **prevent Copilot from processing certain sensitive files**, adding another layer of protection around high-risk content.
5. **Support a complete Copilot governance approach**
- Combined, these capabilities help you set up a **complete solution to secure and govern Microsoft 365 Copilot**.
- This approach aligns with broader industry findings that a significant share of **AI projects now include a security component**, and that **AI-related security incidents often involve data compromise** (sources cited in the template include KPMG and IBM’s *Cost of a Data Breach Report 2025* and *Securing generative AI*, May 2024).
By using Purview alongside Copilot, you can rethink how you manage access, reduce oversharing, and give teams the benefits of generative AI with more confidence in your data protections.
