AT TOKYO Offers Data Deletion and Destruction Services Compliant
With International Standards
Data Deletion and Destruction That Meets Customer Standards Performed
at Data Centers

AT TOKYO Corporation

AT TOKYO Corporation (President and Chief Executive Officer: Akira Nakamura. Henceforth “AT TOKYO”) announces that as of today it will begin providing new data deletion and destruction services that go above and beyond existing services.

For the data deletion and destruction services, AT TOKYO will delete and destroy client data recording media or its data when it is no longer needed, without the need to move the media out of the data center. Specialist technicians using dedicated machinery will perform logical deletion, physical destruction, or magnetic deletion of recording media (such as HDDs and SSDs) to reliably delete and destroy data within AT TOKYO’s data centers or at locations specified by clients.



These services can be used on HDDs, SSDs, CDs, DVDs, SD cards, USB memory devices, floppy discs, and various other types of media.  In addition, deletion will be performed in compliance with security standards of many countries, or with the security criteria and standards adopted by the client.



In disposal of data recording media that is no longer used, removal of the media from the data center could become a risk in its own. In response to calls from customers that want to avoid those risks and dispose data recording media within our data centers, AT TOKYO previously offered some physical destruction and magnetic deletion services.  This time, AT TOKYO is cooperating with TES-AMM Japan K.K., a member company of the TES-AMM Group and a leading global-scale provider of IT equipment management services, to develop and provide greatly enhanced services.



Details of the new AT TOKYO data deletion and destruction services and data deletion and destruction methods are described below.




【Details of the AT TOKYO Data Deletion and Destruction Services

This service provides data deletion and media destruction of data recording media to customers using AT TOKYO Data Centers without the media leaving the data center where they are used.
Specialized technicians using dedicated machinery will perform reliable data deletion and destruction of recording media (such as HDDs and SSDs) within AT TOKYO’s data centers or at client specified locations.




【Data Deletion Methods】


■Logical Deletion

Data deletion by overwriting all sectors of an HDD with dummy data. Logical deletion is effective in cases where physical destruction is not possible such as upon return of leased equipment.


■Physical Destruction and Deletion
Dedicated equipment is used to punch or shred recording surfaces.
Punch destruction pushes a metallic punch, with four pins for HDDs and 40 pins for SSDs, through the drives.
Destruction using dedicated shredders reduces the media into fragments ranging from 2 mm to 40 mm.
Low-noise, low-vibration, and low-dust shredders are used, and they can be used at customer sites as well.


■Magnetic deletion
A powerful magnetic field is used to degauss entire hard disks (18,000-gauss electromagnetic field). Magnetic deletion is an effective method that provides the same level of security as physical destruction and shredding.
Magnetic deletion is effective in cases where the equipment is already dead and logical deletion software cannot run, and are also effective against magnetic tape and tape cartridges.


■Media sanitizing using combination of the above*1
By using a combination of the above deletion methods, sanitizing services that comply with customer needs, industry-specific security standards, or national standards can also be provided.
Services comply with NIST 800-88-r1*2, DoD 5220.22-M*3, and DIN 66399*4, data deletion guidelines that are broadly referenced internationally.




【Other Supplementary Services】


■Certificate Issuance
Data destruction certificates and data deletion certificates are available. Certificates can be issued in Japanese or English.


■Effective use, reuse, and recycling of resources
AT TOKYO contributes to society by providing referrals for the sale of disused equipment, and recycle and use of shredded equipment as raw materials. We have run a zero landfill operation of our data centers.


AT TOKYO has always placed the highest priority on the security of customer data.

We have also designed and operated energy efficient and environmentally-conscious data centers.


Going forward, AT TOKYO will respond flexibly to customer requests while providing high-quality, highly-reliable data center services at the world’s highest levels on a 24-hour, 365-day basis for mission critical applications and expanding and enhancing services so that o

ur data centers are valuable locations for customers.





■Endorsement from TES-AMM JAPAN K.K. CEO Nobumasa Takahashi■

As the importance of problem-free data security management increases in our society, I feel the tremendous burden of responsibility to society regarding the provision, in collaboration with AT TOKYO’s world-leading data centers, of data deletion and destruction services that comply with the world’s highest standards, by our TES-AMM Group. As AI and the IoT (Internet of Things) becomes established as social infrastructure, the proper disposal of ICT equipment requires not just data security but also environmental consideration and compliance. The TES-AMM Group, which support ICT equipment as it evolves on a daily basis and provides a variety of high-quality services at 30 direct sites in 20 countries around the world, will share this value with AT TOKYO, a firm that has gained the confidence of leading-brand companies, to release new services. We will strengthen our ties with AT TOKYO in the future and continue to provide even more needed services.
