Video calls, screen sharing, and personal device boundaries

Remote work runs on video calls, and video calls create their own ways to leak information: what you share, what's visible behind you, and who can hear you.

Screen sharing hygiene

Before sharing your screen, close everything you don't need: email, chat, browser tabs, and any document unrelated to the meeting. Notifications are the classic failure, a message preview about one client popping up while you present to another. Turn on do-not-disturb before you share. Prefer sharing a single window rather than your whole desktop, so a stray click can't expose something else. When the relevant part of the meeting ends, stop sharing; don't leave your screen broadcasting while the conversation moves on.

Who's around, and what's behind you

Check what your camera shows. A whiteboard of client names or a pinned org chart behind you is readable to everyone on the call and to anyone who screenshots it. Use a blurred or virtual background if your surroundings are sensitive. Think about who can hear the call too: sensitive discussions need a closed door, not a shared kitchen. Wear headphones so the other participants' words aren't broadcast to your household, and remember the smart speaker guidance from Section 1.

Photos of screens

Taking a phone photo of your screen creates an uncontrolled copy of work information on a personal device, outside every protection your organisation has. It ends up in your camera roll, synced to your personal cloud, and one mis-tap from being shared. If you need to capture or move information, use approved tools. The same goes for photographing documents.

BYOD boundaries

If your organisation permits work on personal devices, that permission has limits. Typically it covers specific apps, like a managed email profile, and comes with conditions: a screen lock, up-to-date software, encryption, and the organisation's right to wipe its data from the device. Respect the boundary. Don't forward work material into personal apps because they're more convenient, and don't let family members use the profile or apps that hold work data.
