Zero trust and AI: A synergistic approach to next-generation cyber threat mitigation

The increasing sophistication of cyber threats necessitates a shift from traditional security models to more resilient frameworks. Zero Trust Architecture (ZTA) represents a vital security approach that mandates trust for no entities, whether inside or outside organizational boundaries. AI integration to ZTA makes the framework more adaptable through its real-time threat detection system and continuous authentication protocols, together with automated security responses. Artificial Intelligence applied to Zero Trust models investigates network activities to detect irregularities, which allows them to implement detailed authorization mechanisms to stop insider threats and AI-based cyber assaults and APTs. The research investigates the joint operation of AI and Zero Trust through AI security models that deliver elevated functionalities for automated processes, assessment, and data analysis. Real-world deployment of AI-based Zero Trust frameworks is assessed through three different industry sectors including financial, healthcare, and enterprise. The study reveals that AI decreases exposed areas, enhances security decisions, and continuously detects system vulnerabilities. This paper helps progress modern security frameworks because it demonstrates how AI functions as a basic component to develop advanced protective strategies against threats.
