In In the era of cyber threats evolving at lightning speed, the multinational companies (MNCs) must also incorporate an AI-driven cybersecurity framework to detect the threat, prevent intrusion, and manage the data security to continue to stay afloat. Using federated learning-based security models combined with ABSorbed ML, ABSorbed DL, and ABSorbed NLP, the AI-powered three-phase cybersecurity architecture is presented in this research for data management, intrusion detection, and real-time threat intelligence. In addition to the NSL, CICIDS, and UNSW-NB15 datasets, several AIs are used to train the AI using the AI, viz., Random Forest, XGBoost, CNN_LSTM Hybrid, Autoencoders, and Federated Learning AI in order to experiment with the effectiveness of intrusion detection. Federated Learning greatly outperformed standard security protocols: they found that Federated Learning had a collection of values of 99.0 percent accuracy and a minimum false positive rate. Few algorithms employing the use of NLP and AI for automated threat analysis had enabled proactive security intelligence, reduced detection reaction time by orders of magnitude, and enhanced IDS for intrusion detection systems. In addition, federation encryption methods also reduced the cost of computation by 2.5% and ensured high-performance data protection with homomorphic encryption and zero trust architecture (ZTA). Even in learning cybersecurity using AI-based frameworks, the adversarial attacks had suffered strong resistance, and through the usage of federated learning, the attack success rate under PGD attacks was lowest, with just a success rate of 8.5%. There are, however, several important subjects related to AI related to ethical issues, regulatory compliance, and responsibility. It leads research aimed at enhancing improved AI governance models, explainable AI (XAI), and adversarial AI defensive mechanisms for strengthening cybersecurity infrastructures in multinational corporations. After all, if used well, an AI-integrated cybersecurity framework can be utilized by MNCs to create scalable, flexible, and resilient security architecture with solid cyberthreat prevention and safe data management capabilities. Future research can also encompass a study on the federated AI cybersecurity protocols, quantum-safe cryptographic AI models, and improvements in the real-time monitoring tools in order to boost the performance of AI-driven cybersecurity defenses.
