Paper Shredder Security Levels Explained

Shopping around for a paper shredder? If you are, no doubt you have seen shredders tagged with a security level. What is a shredder security level and which one is best for you? I will explain the different security levels here.

There are a total of six paper shredder security levels, with one being the lowest and least secure and six being the highest and most secure. The average person will normally not need anything above a security level three. Most businesses will never need anything above a security level four. Levels five and six are designed for the most secure and top secret documents.

The shredder security level system, except for level six, was designated by the Deutsches Institut für Normung (DIN). The DIN is the German national organization for standardization. The exact DIN label for shredding measurements is DIN 32757.  Security level six specifications were designated by the U.S. government.
