Perimetry Research
Studies of how well public bodies, and the .fr domains as a whole, protect their websites and e-mail, measured with the same passive checks as Perimetry Cloud. Each study is repeated every quarter, so progress shows. We name the good performers, never the others, and report serious issues privately first.
