What does Zeroize mean in cybersecurity?this means erasing electronically stored data in a way that it cannot be retrieved.
What is the primary purpose of zeroization in a cryptographic device?
A method of erasing electronically stored data, cryptographic keys, and credentials service providers (CSPs) by altering or deleting the contents of the data storage to prevent recovery of the data. In this Recommendation, an action applied to a key or a piece of secret data.
DEFINITIONS

How does zeroization work?
Zeroization erases all potentially sensitive information in the router memory. This includes the erasure of the main memory, cache memories, and other memories containing packet data, NVRAM, and Flash memory. The Zeroization button on the faceplate is used to invoke zeroization.
