The exponential increase in cyberattacks, ranging from sophisticated ransomware to state-sponsored espionage, has highlighted the limitations of traditional rule-based security mechanisms. Artificial Intelligence (AI) has emerged as a transformative force capable of augmenting cybersecurity defenses by learning complex patterns, detecting anomalies in real time, and autonomously responding to threats. This review presents a comprehensive overview of the integration of AI techniques in cybersecurity and threat detection. It analyzes the evolution of AI-driven defensive systems, compares machine learning (ML) and deep learning (DL) approaches for intrusion and malware detection, and evaluates their performance using standard datasets such as NSL-KDD and CICIDS2017. The study further explores advanced paradigms like reinforcement learning and natural language processing in phishing prevention, alongside hybrid models that combine multiple algorithms for improved robustness. In addition, the article examines major challenges—including data imbalance, adversarial evasion, and explainability—as well as ethical and privacy concerns. Finally, it identifies emerging trends such as federated learning, quantum-enhanced AI, and explainable AI frameworks for autonomous cyber defense. The synthesis aims to provide researchers and practitioners with a consolidated understanding of how AI is reshaping cybersecurity, outlining both its potential and its inherent vulnerabilities.
