A Particle of Security.....Destruction is a process--not a particle.

A very important perspective regarding document destruction.

"When considering a commercial document destruction service, don't focus soley on the size of the shredded material. Consider instead the company's data destruction process as a whole to include; collection, staging, transfer of custody, acceptance of fudiciary responsibility, processing (destruction), and the disposal of destroyed material. The process also includes employee screening and monitoring, access control, employee training, policies and procedures and audit trails."
