Sold Secure: Security Product Testing & Approval (Sold Secure)

Sold Secure, established in 1992 and backed by the UK Home Office, tests and certifies security products, including bicycle locks, for theft resistance. Products are assessed through manual attack testing at the Master Locksmiths Association facility. Four certification levels—Bronze, Silver, Gold, and Diamond—reflect increasing resistance to attack, from opportunist to professional thieves. Approved products bear the Sold Secure mark, and information is shared with police, insurers, and the public. Sold Secure’s standards help consumers and industry identify trustworthy security products and encourage manufacturers to improve anti-theft technology[6].
