This process is essential for improving defenses and preventing future incidents. When successful attacks go unreported, the knowledge gained from the incident remains within a silo, hindering the organization's ability to learn from mistakes and bolster security measures.

Secondly, internal reporting triggers a series of response protocols, such as incident response teams investigating the breach, preserving evidence, and ensuring that all affected systems are fortified. This proactive approach is vital in managing the fallout from the attack and maintaining overall resilience.

This lack of transparency can ultimately allow other vulnerabilities to persist, increasing potential risks and threats.

While notifying the public, the police, or examining access rights are also important practices, they do not carry the same immediate risk to the integrity of the organization's
