URL rewriting, a service designed to neutralize malicious URLs by redirecting users to a safe environment, has been a common practice in email security. However, as cyberthreats evolve, it's becoming clear that this approach has limitations and potential vulnerabilities.

The approach involved rewriting potentially harmful URLs so that when clicked, they would first go through an analysis engine to determine their safety.
