JOSCAR – the Joint Supply Chain Accreditation Register – is the recognised accreditation system for suppliers working within the aerospace, defence and security sectors. Managed by Hellios, it connects nearly 40 buying organisations across the UK – including the Ministry of Defence – with pre-qualified suppliers, reducing the time and duplication involved in supplier checks across the supply chain. Base3 is now a JOSCAR registered supplier.
What it means to be a JOSCAR Registered Supplier
For organisations working on defence programmes, supplier qualification is a necessary but time-consuming part of the process. JOSCAR simplifies that by holding a single, validated supplier profile that buying organisations can access directly – covering capability, compliance, information security, and financial standing.
In practical terms, if you’re looking for an IT or cyber security supplier for a defence programme and need to verify that they meet the required standards, we’re already on the register. Which means that’s one less thing for you to worry about.
How this fits alongside our other credentials

JOSCAR registration sits naturally alongside Base3’s existing defence sector credentials:
- We are an approved Defence Cyber Certification (DCC) body, supporting MOD suppliers through the DCC scheme against Defence Standard 05-138
- We are an approved Cyber Essentials and Cyber Essentials Plus certification body, recognised by IASME and the NCSC
- We are ISO 9001:2015 certified, demonstrating independently audited quality management across all our services
- We are an AWS Partner, bringing certified cloud expertise to defence and security environments
Together, these credentials reflect a consistent commitment to meeting the standards that defence sector organisations expect from their suppliers – not as a box-ticking exercise, but as part of how we work.
