bitConcat engineers high-assurance, safety-critical software for UK defence contractors, government bodies, and public sector organisations. 25 years of trusted delivery under the highest expectations for security, reliability and compliance.
In defence and government, there are no second chances. Our engineering philosophy is built around this reality — every decision made with security, resilience and compliance as first principles.
Security is designed into every system from the first line — never retrofitted. Zero-trust, least-privilege, defence-in-depth.
Rigorous testing, assurance and audit processes built into delivery. Evidence trails, not assumptions.
Headquartered in Manchester. Full accountability under UK law, with nearshore delivery options available.
