About Us

PESTL Embedded — short for Product Engineering for Secure Technologies Leveraging Embedded — is a UK-based consultancy specialising in the design and development of secure embedded systems.

We help businesses integrate robust security practices into their embedded product development process, from concept to production. Whether you’re building industrial equipment, specialist devices, or consumer electronics, we ensure your solutions are efficient, resilient, and secure by design.

Our founder brings a decade of experience working with embedded devices spanning software, firmware and hardware integration. From developing control systems for mining equipment to writing highly regulated software and firmware in the cyber/defence sectors, this broad background enables us to bridge the gap between hardware reliability and software security.

PESTL Embedded exists to help organisations that recognise the importance of security, reliability, and performance in their embedded products — and want expert guidance in making that vision a reality.

Secure design is not an afterthought — it’s the foundation of great engineering.
