A New Way to Keep Your Screen Secure in Public Spaces

We recently started working with a new client whose team often works remotely – in cafés, co-working spaces, and on trains. During onboarding, they shared a concern that’s becoming more common: how do you protect sensitive information when working in public?

One of their staff had been reviewing confidential documents on a train when they noticed someone nearby glancing at their screen. It was a subtle moment, but it sparked a bigger conversation about privacy risks outside the office.

Microsoft Might Have an Answer

A new feature called Onlooker Detection is reportedly in development for Windows 11. It’s designed to spot when someone is trying to view your screen and alert you.

Depending on your settings, it could:

• Dim the screen to make it harder to read
• Send a warning notification
• Or do both

This builds on Microsoft’s existing Presence Sensing technology, which already locks or dims your screen when you step away. The new feature adds a layer of real-time protection while you’re actively working.

What You’ll Need to Use It

To make this work, your device needs a presence sensor – technically known as Human Presence Detection (HPD). It’s found in newer laptops, especially those using chips from Qualcomm, AMD, or Intel.

If you’re unsure whether your device supports it, you can check by going to: Settings > System > Power & battery

Some of our clients are already reviewing their hardware to see if they’ll be compatible. For teams working in public or hybrid environments, this could be a valuable upgrade.

Why It Matters for Businesses

Privacy isn’t just a personal issue – it’s a business risk.

We’ve seen cases where sensitive client data, financial reports, or internal communications were exposed in public settings. Even a quick glance from a stranger can lead to unintended consequences.

This feature could help prevent:

• Accidental data exposure
• Breaches of confidentiality
• Violations of internal privacy policies

And because it works automatically, it doesn’t rely on staff remembering to be cautious. That’s a big win for busy teams.

What’s Next?

While Microsoft hasn’t officially confirmed the release date, Onlooker Detection has appeared in Windows 11 preview builds. That’s usually a strong sign that it’s on the way.

In the meantime, we recommend:

1. Reviewing your current devices for HPD compatibility
2. Updating privacy policies to include public working environments
3. Training staff on best practices for working securely in shared spaces
4. Look into physical privacy screens for laptops, not as sleek as a built in solution but very effective when used. We have had great sucess with this Privacy Screen from Amazon. (Please note we receive a commission on any sales made using this link, commission paid for by the seller.)
