SCI Semiconductor Limited

SCI Semiconductor is a global leader in advanced, cyber security-focused semiconductor solutions serving critical national infrastructure, industrial automation, aerospace, and the broader IoT ecosystem.

A VC funded, fabless semiconductor company, SCI Semiconductor is leveraging memory safety CHERI (Capability Hardware Enhanced RISC instruction) technology to develop high security and critical IP for applications that require exceptional reliability and cyber resilience from the silicon upward.

The company’s flagship family of high-integrity microcontrollers, “ICENI” delivers secure-by-design protection, fully memory-safe computing. ICENI enables robust software isolation, scalable security, and comprehensive defence against memory-safety vulnerabilities. SCI’s hardware-enforced cybersecurity uniquely provides 100% memory safety across target markets.

With a robust co-designed software and hardware platform, SCI transitions digital security from a high-cost “businesses insurance” technology to simple-to-implement solutions, reducing development costs, time to market, and lifecycle patching and remediation. These capabilities empower enterprises to build smarter, safer and more secure systems.

Commercially, SCI has secured over £10M in contracted revenue, two global hyperscaler lead customers in the telecom sector, and a pipeline of 30+ OEM engagements with 10 initial design wins.

The company’s leadership team has deep knowledge in microprocessor IP, cybersecurity and semiconductor development, drawing on experience at Arm, AMD, Microsoft, Rambus, Broadcom and NXP. Its advisory board includes senior figures from academia, defence and national-security communities, strengthening SCI’s capacity to deliver trusted, high-assurance technologies.
