Phishing has become complex enough to warrant real-time security solutions because the threat now exists at an alarming frequency. The research investigates the multiple attack methods in phishing campaigns along with an examination of standard protection approaches’ weaknesses. The research investigates sophisticated artificial intelligence (AI) and machine learning (ML) systems because they present improved detection and faster prevention capabilities against phishing attempts. The paper delivers a complete examination of AI-based cyber defense systems while analyzing their position in enhancing business cybersecurity structures. The research adopts a position that intelligent adaptive defenses ought to be integrated because AI technologies serve as a proactive method to reduce risks in modern phishing attacks.
