As cloud infrastructure becomes the backbone of modern enterprise operations, securing this digital frontier has evolved into a multidimensional challenge. The traditional perimeter-based defenses are no longer sufficient in the face of increasingly sophisticated cyber threats. Artificial intelligence and generative AI (GenAI) are now being explored for their potential role in how organizations detect, respond to, and mitigate security risks in cloud environments. From real-time anomaly detection to predictive threat modeling, AI is augmenting human capabilities and automating complex workflows, enabling faster and more accurate security decisions.
