On your sites and servers

The two pieces of CheckRoost that run on your own machines, documented in full before you install them.

Everything else CheckRoost does happens from the outside and needs nothing installed. These two report what only the machine itself can see — plugin updates and files that should not be public on a WordPress site, disk and memory on a server — and each says what it reads and what it refuses to do before it says how to install it, because that is where the decision to install is made. Both refuse an update that is not signed.
