SafeRec exclusively works with two standard shadow masks of 6 and 20mm. If you follow the safety standard H for hard discs and use a 20mm shadow mask you can achieve the H-5 standard. This means a guaranteed security for confidential information. Our final product however will be further crushed to even smaller pieces using the facility of a partner plant. By this additional step we ensure a complete destruction of all your data.
