WebNamed after its developer, the Gutmann algorithm is a method of disk wiping that overwrites data using a total of 35 passes. This makes it one of the most secure data erasure methods, but also the most time-consuming. The primary benefit of data wiping and erasure is that it can often be done on-site with widely available software tools.
