Shredder Security Levels

An explanation of the DIN security level rating system

Shredders are generally advertised based on the type of cutting that they do. For example, strip-cut shredders cut documents into long, vertical strips. Cross-cut machines shred the documents both horizontally and vertically. However, there is also a security level rating system that can inform consumers about how secure the shredded documents really are. This is based not only on the shredder's cutting method, but the size of the paper left over once it's cut.

The standard security level system comes from Germany and is called the Deutsche Industrial Norm (DIN). There are five security levels in the DIN system (as well as an unofficial sixth that is used almost exclusively by the military and secret service).
