Phishing attacks remain one of the most common cybersecurity threats faced by organizations today. These attacks involve deceptive attempts to trick individuals into revealing sensitive information such as passwords, credit card numbers, or personal data. Effective detection and response strategies are essential to safeguarding organizational assets and maintaining trust.
