AI and Oversharing: Who Can See Your Business Data?

AI and Oversharing: Who Can See Your Business Data?

Generative AI is changing how employees find, summarise and use business information. Tools such as Microsoft 365 Copilot can help people work more efficiently, but they also make it important to understand exactly what information employees are permitted to access.

And that's where things can get interesting.

Many organisations have files, folders and SharePoint sites that have accumulated permissions over time. Access may have been granted for a project, shared with a wider team or simply never reviewed.

Introduce AI into that environment and information that was previously difficult to find may suddenly become much easier to discover.

The important distinction is that enterprise AI tools such as Microsoft 365 Copilot respect existing permissions. They don't automatically give employees access to information they weren't authorised to see.

But they don't fix overly broad permissions either.

Why does AI oversharing matter?

An employee might have legitimate access to a document without necessarily needing that information for their current role.

AI-powered search and summarisation can make that information easier to surface, increasing the importance of reviewing existing access arrangements.

Before introducing AI across your organisation, it's worth asking:

  • Do employees have access to more information than they need?
  • Have SharePoint and Microsoft 365 permissions been reviewed recently?
  • Is sensitive information appropriately classified and protected?
  • Are external sharing arrangements properly controlled?
  • Do you understand which business information your AI tools can access?

Getting AI ready starts with understanding your data

AI governance isn't just about deciding which tools employees can use. It's also about making sure the right information is available to the right people.

Reviewing permissions, addressing oversharing and applying appropriate data protection controls can help organisations benefit from AI without introducing unnecessary exposure.

Watch our short video to understand why existing permissions matter when introducing AI into your workplace.

Have a question? You may find the answer here!

Can AI governance tools help with compliance?

Yes. Auditors are generally more impressed by evidence than assurances that everyone has been very sensible.

Governance platforms can help document AI systems, policies, risks, controls and responsibilities, as well as collect evidence showing that those controls are operating. This can support frameworks such as ISO 42001 and the NIST AI Risk Management Framework and help organisations prepare for relevant regulatory obligations.

Can we see who is using AI and how often?

Yes. “Someone in Marketing, probably” can be narrowed down considerably.

Usage monitoring can provide visibility into which supported AI applications are being accessed, by whom and how frequently. This helps identify adoption patterns, unexpected tools and areas where additional guidance or controls may be needed.

Can we protect against malicious AI prompts?

Yes. Apparently prompts need cybersecurity now too.

Some AI protection platforms can detect potentially harmful prompt techniques, including prompt injection, and either alert on or block them. This becomes increasingly important as AI services and agents interact with business data and other systems rather than simply generating text.

Can we monitor AI first without blocking anything?

Yes. Sometimes finding out what’s happening before stopping it is surprisingly useful.

A sensible starting point can be a monitoring or detect-only period. This provides visibility into the AI tools people are already using, which departments rely on them and where sensitive-data risks exist. You can then introduce controls based on real usage rather than guesswork.

Can we govern AI agents as well as chatbots?

Increasingly, yes, and agents make governance considerably more important.

AI agents may be able to access applications, databases, files and other tools and take actions rather than simply answer questions. Governance therefore needs to consider what each agent can access, what it is permitted to do, who owns it and how its activity is monitored.

Can we detect confidential information being pasted into AI?

Yes. Because asking everyone to “please be careful” has its limits.

Data loss prevention controls can inspect supported AI interactions for sensitive or regulated information and either record the event or prevent the information from being submitted. This adds a technical control behind your AI policy rather than relying entirely on employees remembering it.

Can we block AI tools such as ChatGPT?

Yes. Although blocking everything is rarely the most imaginative AI strategy.

AI security controls can restrict access to particular AI applications or services based on your organisation’s policy. You might block some completely, allow approved alternatives or simply monitor usage first so you understand what people are actually using before making a decision.

Can we allow ChatGPT but stop staff entering sensitive information?

Yes. Access to the tool and permission to give it your customer database are two different things.

AI protection technology can inspect supported prompts and uploads for sensitive information and either alert on or prevent certain data from being submitted. That can include personal, financial, health or confidential business information, depending on the controls and policies you put in place.
