AWS Launches Strands Box to Mitigate AI Agent Risks Amazon Web Services (AWS) has introduced Strands Box, an open-source sandbox designed to control AI agents' behavior by combining operating system-level isolation with activity-aware policies. Released on October 7, 2026, Strands Box aims to enhance security as enterprises increase AI agents' access to applications and data. The tool utilizes Dogwood, an open-source policy language, to evaluate agents' actions based on their past behavior, allowing for more nuanced restrictions without relying solely on the agents' compliance. For instance, it can limit an agent's ability to post updates in a Slack channel to prevent flooding. While Strands Box addresses significant security gaps, it also introduces potential complexities and overhead. AWS acknowledges that not all actions are covered by Dogwood's policies, and there are concerns about the security of components running outside the sandbox. The tool currently supports Macs with Apple silicon processors running macOS 15 or later. 3 sources 28
