About Corrasure

Independent Certification & Assurance Specialists

Trusted support for the Certification, Airworthiness and Assurance of Safety and Mission critical systems. Corassure is a specialist consultancy providing independent certification, assurance and regulatory-facing expertise to defence and aerospace programmes. We support organisations developing complex, software-intensive and cyber-enabled systems where regulatory approval, safety and security are critical to success. Our work spans the full lifecycle - from early concept and architecture, through development and integration, to formal certification, approval and in-service assurance.

Our Approach

Corassure exists to help delivery teams navigate the complexity of modern regulated systems. We work at the intersection of engineering, safety, security and regulation, supporting programmes that must satisfy demanding certification and assurance frameworks. Our team brings real-world experience from certification authorities, design authorities and senior technical leadership roles.

We don’t provide theoretical advice, we work directly with programmes to build evidence, close gaps, and achieve approval with confidence. We regularly support programmes operating under UK and European military and civil airworthiness, defence safety and secure systems regulatory frameworks, as well as selected civil standards where appropriate.
