From the report: "HCSEC is a facility in Banbury, Oxfordshire, belonging to Huawei Technologies (UK) Co Ltd, whose parent company is a Chinese headquartered company which is now one of the world’s largest telecommunications providers. HCSEC has been running for seven years. It opened in November 2010 under a set of arrangements between Huawei and HMG to mitigate any perceived risks arising from the involvement of Huawei in parts of the UK’s critical national infrastructure. HCSEC provides security evaluation for a range of products used in the UK telecommunications market. Through HCSEC, the UK Government is provided with insight into Huawei’s UK’s strategies and product ranges. The UK’s National Cyber Security Centre (NCSC, and previously GCHQ), as the national technical authority for information assurance and the lead Government operational agency on cyber security, leads for the Government in dealing with HCSEC and with Huawei more generally on technical security matters."
