How it plays out on a deal
Fence view targets a specific risk: someone photographing a screen, or a passer-by reading a document in a shared office. Because only a strip of the page is legible at a time, a single capture shows very little.
It slows reading noticeably, so it is normally applied to a handful of very sensitive files rather than a whole room. Not every platform offers it; when one does, it is worth checking whether it can be required for a specific folder or group rather than only switched on room-wide.
What to check in a review or demo
- 1Whether fence view can be required for selected files or groups only.
- 2Whether it works on tablets and phones, or blocks mobile viewing instead.
- 3How readable a dense contract is in fence view at normal screen size.
Read alongside
- Screenshot protectionMeasures that try to stop or deter screen captures of documents in the viewer, such as blanking the page when a capture tool is detected or when the window loses focus.
- Dynamic watermarkingAn overlay stamped on a document at the moment it is viewed, printed or downloaded, showing details such as the reader's name, email, IP address and the time.
- Secure viewerThe in-browser document viewer a data room uses to display files without handing the reader the original, so protections such as watermarks and copy limits can apply.
- View-only accessA permission that lets a user read a document in the room's viewer but not download, print or edit it.
