"secure" eh?

"Secure" workplaces means that you have to have the appropriate clearances and background checks to be allowed in and out. I'm sure there are more secure workplaces, but the security of your average SCIF largely depends on the people allowed inside of it not being bad actors.

Outside of strip searches upon arrival and leaving I'm not sure how you could eliminate that risk.
