🔐 Introduction
Despite the best tools, training, and awareness, phishing
emails still get through. Even the most security-conscious people can be
caught off guard. That’s why it’s critical to have a clear, structured
response and recovery plan in place.
In this final chapter, you’ll learn exactly what to do if
a phishing email is opened, clicked, or acted upon — whether at the
individual level or as part of a company’s incident response strategy. We’ll
also cover post-incident forensics, notification responsibilities, and
long-term recovery and hardening techniques.

🧠 Summary
Phishing prevention is powerful — but when prevention fails,
swift response and smart recovery are everything. The way an
organization handles a phishing incident directly affects its reputation, legal
standing, and operational continuity.
By building a resilient incident response system,
empowering employees, and learning from each incident, you can turn every
phishing attempt into a valuable opportunity for strengthening your defenses.
