Through granular access controls, micro-segmentation, and relentless authentication, zero trust significantly reduces the attack surface and limits the potential devastation a successful breach can cause.

Let’s contextualize this concept within another paradigm from computer science known as divide and conquer. This algorithmic approach involves continually breaking down a larger problem into smaller, more manageable components until they are easily solvable.
