Red Team vs Pentest vs Purple Team

These three words get used interchangeably in sales decks and they should not be. A penetration test counts holes in a wall. A red team checks whether anyone notices a person climbing through one. A purple team puts the climber and the watcher in the same room until the watcher learns to spot the climb every time. Same people, same tools, completely different questions — and buying the wrong one wastes a quarter of your security budget.
