Shredder Security Levels: Explained

Shredders are an essential tool for keeping sensitive information confidential. There are different levels of paper shredder security, each with its own set of standards and requirements. Understanding the security levels of paper shredders can help you make an informed decision when selecting a shredder to meet your needs.

What are the Differences Between Cut Types on Shredders?

Shredder cut types are organized into four different categories, or levels. These define the security level of a shredder, which is based on the number of paper pieces from a single sheet of paper cut by its blades.

Level 1: Strip-Cut Shredders

Strip-cut shredders are the most basic type of paper shredder. They cut documents into long, narrow strips. This type of shredder offers the lowest level of security, and is suitable for shredding non-sensitive documents that do not contain personal or confidential information. Strip-cut shredders are typically less expensive and faster than other types of shredders.

Level 2: Cross-Cut Shredders

Cross-cut shredders are also commonly known as confetti-cut shredders. They cut documents into small, square pieces that are more secure than the long, narrow strips produced by strip-cut shredders. Cross-cut shredders offer a higher level of security, and are suitable for shredding documents that contain sensitive information such as bank statements, medical records, and credit card receipts.

Level 3: Micro-Cut Shredders

Micro-cut shredders are also known as particle-cut or diamond-cut shredders. They cut documents into tiny particles that are much smaller than the pieces produced by cross-cut shredders. Micro-cut shredders offer the highest level of security, and are suitable for shredding highly sensitive documents such as classified information, government documents, and financial records. They are slower and more expensive than strip-cut and cross-cut shredders, but offer the highest level of protection.

Level 4: High-Security Shredders

High-security shredders are designed for organizations that need the highest level of document security. They are capable of shredding documents into particles that are even smaller than those produced by micro-cut shredders. These shredders are typically used by government agencies, financial institutions, and other organizations that handle highly sensitive information.

In addition to these levels of shredder security, some shredders come with additional security features such as jam prevention, automatic shut-off, and noise reduction. When selecting a paper shredder, it is important to consider the level of security and features that will best meet your needs.

P-Ratings Explained

The P-rating system is a classification system used to categorize paper shredders based on their level of security. The P-rating system was developed by the National Security Agency (NSA) in the United States to provide a standard for evaluating how effective paper shredders are at destroying sensitive information.

The P-rating system is divided into six levels, from P-1 to P-7, with P-1 being the lowest level of security, and P-7 being the highest. The P-rating system is based on the size of the particles that the shredder produces, with smaller particle sizes indicating a higher level of security.

P-1 : This rating indicates that the shredder produces strips that are no wider than 12mm (0.47 inches). This level of security is suitable for shredding non-sensitive documents that do not contain personal or confidential information.

P-2: This rating indicates that the shredder produces strips that are no wider than 6mm (0.23 inches). This level of security is suitable for shredding documents that contain sensitive information such as bank statements, medical records, and credit card receipts.

P-3 : This rating indicates that the shredder produces particles that are no larger than 320mm² (0.5 square inches). This level of security is suitable for shredding documents that contain highly sensitive information such as legal documents and financial records.

P-4: This rating indicates that the shredder produces particles that are no larger than 160mm² (0.25 square inches). This level of security is suitable for shredding documents that contain confidential information such as tax records, employment records, and personal identification documents.

P-5 : This rating indicates that the shredder produces particles that are no larger than 30mm² (0.05 square inches). This level of security is suitable for shredding documents that contain extremely sensitive information such as classified documents and top-secret information.

P-6 : This rating indicates that the shredder produces particles that are no larger than 10mm² (0.016 square inches). This level of security is suitable for shredding documents that need the highest level of security, such as government documents and military records.

P-7 : This rating indicates that the shredder produces particles that are no larger than 5mm² (0.008 square inches). This level of security is suitable for shredding documents that need the highest level of security, such as top-secret documents and highly confidential information.

It's important to note that the P-rating system is not used universally, and different countries may have different standards for paper shredder security. However, the P-rating system provides a useful benchmark for evaluating how effective paper shredders are at destroying sensitive information.

Below is a table to help explain how this rating works:

Security Rating

Estimated Pieces (per A4 Sheet of Paper)

P-1

36 (strips)

P-2

75 (strips)

P-3

312 (particles)

P-4

421 (particles)

P-5

2,000 (particles)

P-6

6,000 (particles)

P-7

15,000 (particles)

Do I Need a High Security Shredder?

A high security shredder is typically needed when you have to dispose of documents or other materials that contain sensitive or confidential information that must be kept secure. Examples of situations where a high security shredder may be necessary include:

Financial Institutions: Banks, credit unions, and other financial institutions often deal with sensitive financial information, including account numbers, social security numbers, and other personal information. A high security shredder can help ensure that this information is securely destroyed and cannot be accessed by unauthorized individuals.

Government Agencies: Government agencies at all levels often deal with classified or sensitive information that must be kept secure. A high security shredder can help ensure that this information is properly destroyed and cannot be accessed by unauthorized individuals.

Medical Offices: Medical offices, hospitals, and other healthcare providers often deal with sensitive patient information, including medical records, insurance information, and personal details. A high security shredder can help ensure that this information is securely destroyed and cannot be accessed by unauthorized individuals.

Legal Firms: Law firms often deal with confidential legal documents, such as client contracts, court filings, and case records. A high security shredder can help ensure that these documents are securely destroyed and cannot be accessed by unauthorized individuals.

In general, if you are dealing with any type of confidential or sensitive information, it is important to consider using a high security shredder to make sure that this information is properly destroyed and cannot be accessed by unauthorized individuals.
