The ThreatLabz 2026 AI Security Report provides a data-driven analysis of how artificial intelligence is being integrated into modern corporate infrastructure. Drawing from nearly one trillion transactions, the report highlights an 83% increase in AI activity, with tools like Grammarly, ChatGPT, and Codeium leading the surge. While these technologies drive significant productivity gains in departments like engineering and IT, they simultaneously expand the enterprise attack surface through massive data transfers and potential policy violations. Security teams are responding to these risks by blocking nearly 40% of AI transactions to prevent sensitive data exposure. Ultimately, the research emphasizes that securing sanctioned AI applications is now as critical as defending against external threats. Successful organizations must move toward zero trust architectures to balance rapid innovation with essential risk management.
