Geheimagent is perfect for restrictions, or permissions if you prefer. Not quite a textfont, not quite a headlinefont, it’s a bit of both.
The Italic versions break up the strictness of the regular fonts. They are fast and forward and make a perfect mix with the servere upright uppercases. Try to render the font and trash it up a bit.
Cut it, paste it, it will survive. Because it has already seen everything since its origin as a prohibition sign in an industrial harbour.
