This is what glyph of warding is for isn't it? Just have the sleeper agent feed the party bad passwords or stuff some rats into individual containers and throw them at glyphs (or set up traps that drop caged animals into glyph areas) with area damage spells to force trigger them or do it themselves if immune to the damage type.

Make the entire HQ portable using Structures such as the Pocket Stage for giving announcements, the Portable Gaming Hall for having meetings, and the Private Workshop for doing business. So then in an emergency, the Organization can pack up and move their HQ somewhere unknown - leaving nothing but a warehouse looking building with empty rooms.
Ward Domain always pops to mind in those cases.
As for the good guy vs bad guy thing it's irrelevant, you're telling a story here, it would be sense for the good guys to have several defenses in place that are hasards. Hazards aren't solely the province of the antagonists, they're a thing for GM's to use.
Perhaps some of them even summon creatures of a level on par to be challenging to the PC's.
... 6th level and lower magic (including rituals).Drat.
Hmm...
Dinosaur Fort should be 6th level.
