Technical Director, Clewline.
Technical Community Architect, Linux Foundation CCC.
Sal is a cybersecurity practitioner and technologist with over a decade of experience at the intersection of security, AI, and open source governance. Her career has spanned the Missile Defense Agency, cloud infrastructure startups, and the Linux Foundation.
At the Linux Foundation's Confidential Computing Consortium, she coordinates governance across member organisations including Microsoft, NVIDIA, ARM, and TikTok.
Her book, Code, Chips and Control, addresses technology sovereignty and the geopolitical dimensions of hardware security, subjects that inform Clewline's approach to digital sovereignty consulting.
She holds a PhD from University College London, has been recognised as a Top 100 Woman in AI Ethics (2025) and UK Top 50 Open Source Contributor (2023), and was shortlisted for Security Woman of the Year (2024). She is based in London.
"The decisions being made right now about AI governance will be very difficult to reverse."
Clewline exists because the organisations responsible for those decisions need people who understand the technical reality, not just the regulatory surface.
