Your internal threat model is the bedrock of your organization’s cybersecurity posture. It’s the map you use to navigate the treacherous landscape of potential adversaries who already have a foothold within your digital perimeter. Think of it as the watchful sentinel at the gates of your digital castle, constantly scanning for threats that have already breached the outer walls.
