This is because paper shredding is one of the most effective way of disposing documents containing personal data. As we all know, when data is breached due to such document, a financial penalty may be imposed by the PDPC.

The right shredding size

When choosing how to shred your documents, you will want to consider shred size. The size of the paper shreds affects information security and possibly the cost of your service. Paper shredders use a standard classification system of P2 through P7 to determine the security of the paper being shredded through the blades. Understanding the size of the shred is the most important factor in deciding which machine is right for your needs. The smallest cut size falls under level P7, while the largest size is level P2.

Strip-cut shredders, or P2 shredders, are the most productive, but they are also the least secure. Levels Ps and P4 are the most common for businesses or home use. They are HIPAA compliant and do a great job protecting private information. P6 and P7 shredders are required for government agencies to dispose of top-secret documents, but a P7 shredder is needed for the most demanding destruction of top-secret documents.
