Join us at RSAC 2026 in SF – Annual Gen AI Security Summit and Open Workshop – March 25th

The OWASP GenAI Data Security Risks and Mitigations 2026 guide provides a critical, forward-looking analysis of the unique data security challenges posed by the rapid, widespread adoption of Generative AI (GenAI) across enterprise environments, anticipating the landscape by 2026. This comprehensive guide moves beyond traditional software security paradigms to address the novel attack surfaces that emerge when systems process and generate information at an unprecedented scale. The paper establishes a foundational, open-source framework for securing GenAI systems, focusing intensely on the data layer—from initial training and fine-tuning datasets to user prompts and final model outputs. Security professionals must proactively integrate AI-specific security testing, constant monitoring, and robust validation from the earliest stages of model development through to deployment. Adopting and adapting a comprehensive security framework will be essential for organizations to safely harness the revolutionary capabilities of GenAI while effectively managing its profound data security risks by 2026.
