    Are your security products tested by Sold Secure?

    Recent statistics reveal that over 5000 caravans are stolen every year, highlighting the importance of caravan security. Stronghold security products carry Sold Secure Gold standard approvals* that offers peace of mind and an opportunity for an insurance discount. Sold Secure is widely recognised by the general public, Police Crime Prevention Design Advisors and insurance companies for providing high standards of independent product testing. Sold Secure tests security products to ensure the manufacturers are developing and distributing items that meet their claims. These tests are carried out in accordance with 'Attack Specifications'. The Sold Secure team of approved testers then carry out the attack specifications that applies to each category. For example, caravan security devices are attacked by drills or large pry bars that professional thieves would carry to steal caravans. When a higher level of security is needed, devices approved to Gold standard are recommended. You can check if a product has Sold Secure approval by visiting the Sold Secure website. *with some exceptions, please see individual products for details.
