CSA publishes addendum to guidelines and companion guide on securing AI systems
27 August 2026
On 17 June 2026, the Cyber Security Agency of Singapore (“CSA”) released an Addendum to the Guidelines and Companion Guide on Securing AI Systems (“Addendum”). The Addendum seeks to support system owners in securing their agentic artificial intelligence (“AI”) systems in view of the risks posed by agentic AI.
CSA published the Guidelines and Companion Guide on Securing AI Systems in 2024 to help organisations adopt AI securely. The Guidelines lay out the foundational security principles for system owners to secure the use of AI throughout its lifecycle, while the Companion Guide provides practical measures and controls that system owners may consider in implementing the Guidelines.
While agentic AI possesses sophisticated abilities to understand context, formulate plans, and take independent actions to achieve specified objectives, it also introduces new risks, with greater potential for impact given agentic AI’s capabilities and its access to tools and data.
In view of these risks and the growing interest in agentic AI, CSA has developed the Addendum in collaboration with industry, government, and international partners to support system owners in securing their agentic AI systems. The Addendum is designed to be read alongside the Guidelines and Companion Guide.
The Addendum outlines how risks can be identified and assessed based on the capabilities of agentic AI systems (for example, by mapping out agentic workflows to identify where threat actors could potentially exploit vulnerabilities).
In addition, the Addendum provides practical controls to mitigate relevant risks across the development lifecycle. Practical examples are also provided to illustrate how the Addendum can be applied across different scenarios and levels of system autonomy. These include use cases such as app development and coding assistants, automated client onboarding systems, and automated fraud detection systems.
The public consultation for the Addendum was conducted from 22 October 2025 to 31 December 2025.
