The goalkeeper principle: Why your last line of defense can never fail
The goalkeeper is the only player on the pitch whose mistake immediately costs a goal. No recovery time. No second chance. That’s what makes credential security different from every other control. When it fails, the game is already over. Every other layer in your stack has someone behind it. Endpoint controls, network segmentation, privilege management, and policy enforcement are all players doing a job, each one backed up by another. Credentials aren’t like that. They sit behind all of it.
