Between February and March 2025, I analysed the UK’s Cyber Resilience Testing (CRT) initiative and its associated Cyber Resilience Test Facilities (CRTFs). From that research, I developed three articles: one mapping the global standards landscape, one examining CRT’s practical challenges, and one exploring its role as a trust label. Together, they present CRT as a promising but evolving approach: not yet a standard, but under active NCSC development and consultation, with the potential to reshape product-based assurance if given clarity, support, and ecosystem alignment.
