If an application works natively with Wayland (*not* running through the [XWayland](https://wayland.freedesktop.org/xserver.html) compatibility layer), consider revoking its access to X11 (`--nosocket=x11`) and the [inter‑process communications (IPC)](https://en.wikipedia.org/wiki/Unix_domain_socket) socket (`--unshare=ipc`) as well.

Many Flatpak apps ship with broad filesystem permissions such as `--filesystem=home` and `--filesystem=host`. Some applications implement the [Portal API](https://docs.flatpak.org/en/latest/portal-api-reference.html), which allows a file manager to pass files to the Flatpak application (e.g. VLC) without specific filesystem access privileges. Despite this, many of them [still declare `--filesystem=host`](https://github.com/flathub/org.videolan.VLC/blob/master/org.videolan.VLC.yaml).
