This article presents a study aimed at co-designing technological capabilities to support the protection of UK police officers and staff in public-facing roles. Firstly, we examined the digital literacy of police personnel, their experiences with online harms, and their requirements for a tool to equip them with privacy strategies in their use of digital platforms. These findings informed the design and development of a Self-assessment Tool that enhances police personnel’s privacy awareness and literacy. We discuss the challenges encountered in tailoring the tool to their specific needs and present the final product. The tool is a critical component of a broader strategy to reduce online harms experienced by police personnel as public-facing professionals.
