Certified Erase Protects Data and Enables the Circular Economy
Learn how securely protecting data provides economic value.
In considering the economic and environmental benefits of this device circularity data erasure approach, many customers have expressed a desire to safely and securely sanitize data that has been previously stored on drives. With due diligence, Seagate has partnered with industry standard and regulatory bodies such as the National Institute of Standards and Technology (NIST) and the International Organization for Standardization (ISO), to achieve unified standards for media sanitization.
NIST Special Publication 800-88 Revision 1 is the US federal media sanitization guideline that defines the data risk management framework for various media types, including HDDs and SSDs. Coupling NIST 800-88 with the media sanitization process specified in ISO/IEC2040:2015 provides a common and international baseline for erasure as well as a certificate of erasure.
The standards define a level of erasure known as Purge. Purge applies physical or logical techniques that render data recovery infeasible, whether an actor is using basic methods or state-of-the-art laboratory techniques.
Each of Seagate’s devices support at least one form of Purge erasure as described below:
Most of Seagate’s products sold and used throughout the world provide Purge functionality by implementing Sanitize Overwrite. This method is fully sanctioned by the standards organizations and addresses use cases in countries where encryption is not allowed or in products where it has not been procured. Thus, Seagate considers Sanitize Overwrite erase a method of media sanitization that can be used in a global setting by Seagate customers everywhere.
In addition to the Purge methods described by NIST and ISO, Seagate has developed Certified Erase. Certified Erase uses the same purge sanitization tools discussed above and adds an erasure document to provide certainty and peace of mind that data is unrecoverable. The Certified Erase document of erasure can be verified authentic to an individual Seagate drive. Seagate offers a hardware appliance that performs the Purge erasure methods and produces a signed certificate of erasure automatically for the customer. Those selecting a software implementation can work with our tools group to apply Purge erasure methods using standard interface commands and common Seagate tools.
By offering Certified Erase to customers, Seagate not only focuses on keeping customers’ data safe, but also considers an environmentally responsible circular-device lifecycle that benefits the planet and salvages economic value by promoting device reuse. We are excited about our environmental and economical approach to secure data sanitization and look forward to bringing our customers a higher standard of data security.
