DATA & MEDIA SANITIZATION
Certified Electronic Records Destruction, Aligned with Indonesia's Archives and Personal Data Protection Laws
Datasan helps organizations destroy electronic records and documents that have passed their retention period in a verified, documented, and auditable manner. Every engagement runs under an unbroken chain of custody and concludes with a certificate of destruction as evidence of compliance.
Destroying electronic records is not the same as pressing delete. Law No. 43 of 2009 on Archives and its implementing regulations treat records destruction as part of formal records disposal: it must be based on a Records Retention Schedule (JRA), preceded by appraisal, and documented with an official report and a register of destroyed records. When those records are electronic, these procedural obligations meet a technical challenge — data 'deleted' from a system can often still be recovered from the underlying storage media.
At the same time, Law No. 27 of 2022 on Personal Data Protection (PDP Law) requires data controllers to erase and destroy personal data under certain conditions, such as when the retention period ends or upon a data subject's request. Similar obligations apply to electronic system operators under the Electronic Information and Transactions (ITE) Law and Government Regulation 71/2019. Keeping data longer than necessary has therefore become a legal risk in its own right — as serious as losing data before its time.
The gap between 'deleting a file' and 'permanently destroying data' is exactly what Datasan closes. Using sanitization methods grounded in international practice such as NIST SP 800-88 Rev. 1 — covering the Clear, Purge, and Destroy tiers — Datasan ensures that electronic records approved for destruction are genuinely unrecoverable, while producing a documentation trail ready for internal auditors, sector regulators, and your records management unit.
Why Ordinary Deletion Is Not Enough — and Is Risky
Deleted data can still be recovered
Standard delete or format commands typically remove only the references to data, not the data itself. With readily available forensic tools, 'deleted' records on HDDs and SSDs can often be reconstructed.
No evidence for auditors and regulators
Without an official destruction report, a register of destroyed records, and a certificate of destruction, organizations struggle to prove they have met records disposal and personal data erasure obligations. Verbal assurances do not survive an audit.
Retired media become a leak vector
Decommissioned servers, reassigned laptops, and hard drives that are resold or returned to leasing providers frequently leave the organization without verified sanitization. Data breaches originating from second-hand media happen repeatedly through this gap.
Expired retention compounds PDP exposure
Electronic records containing personal data kept beyond their retention period magnify the impact of any incident and may breach the PDP Law's destruction obligations, which carry administrative sanctions.
End-to-End Verified Destruction of Electronic Records
Sanitization methods grounded in NIST SP 800-88
Datasan applies the Clear, Purge, and Destroy tiers according to media type and data sensitivity — from verified overwriting and cryptographic erase to degaussing and physical destruction of media.
Auditable certificates of destruction
Every media unit and every job produces a certificate of destruction recording the media identity (make, model, serial number), the method used, verification results, execution time, and the responsible parties — ready to be attached to your official destruction report.
An unbroken chain of custody
From media handover to completed destruction, every transfer of possession is logged and signed. You always know where each media unit is, who holds it, and what has happened to it.
Support for diverse media and environments
Coverage spans HDDs, SSD/NVMe, tape, and mobile devices, as well as logical sanitization on live servers and virtualized environments — including selective destruction per file or dataset according to your approved disposal list.
Aligned with your archival and PDP procedures
Datasan's technical process is designed to slot into your formal workflow: appraisal by the records appraisal committee, management approval, official reports, and reporting to compliance and data protection functions.
Datasan is trusted for data and media sanitization by organizations in Indonesia's regulated sectors, including environments with stringent audit requirements.
How the Destruction Process Works
Assessment and scoping
Together with your records management, IT, and compliance teams, we map the electronic records and media whose retention has expired based on your retention schedule and personal data retention policies. The result is a clear destruction inventory, complete with sensitivity classifications and the recommended sanitization method for each media type.
Handover under chain of custody
Media, or access to systems, is handed over formally. Each unit is labeled and its identity recorded; chain-of-custody forms are signed by both parties so accountability for the media is documented without gaps, whether destruction takes place on-site at your premises or at a controlled facility.
Sanitization execution and verification
Destruction is executed using the agreed methods — verified overwriting, cryptographic erase, degaussing, or physical destruction. Every execution is followed by a verification step to confirm the data is genuinely unrecoverable; any failure on a particular media unit is escalated to a stronger method, never ignored.
Certificates, official reports, and delivery
You receive per-media certificates of destruction plus a summary report ready to serve as an attachment to the official records destruction report. This documentation stands as compliance evidence you can present to auditors, sector supervisors, or in demonstrating fulfilment of PDP Law obligations.
Frequently Asked Questions
Is deleting files or reformatting media enough to destroy electronic records?
No. Standard deletion and formatting generally remove only the pointers to data, leaving the content recoverable with forensic tools. True destruction requires verified sanitization methods — such as overwriting, cryptographic erase, degaussing, or physical destruction — selected according to the media type and the sensitivity of the data.
What is the legal basis for destroying electronic records in Indonesia?
Law No. 43/2009 on Archives and Government Regulation 28/2012 govern records destruction as part of disposal, which must be based on a retention schedule, preceded by appraisal, and documented with an official report and register of destroyed records. Where records contain personal data, Law No. 27/2022 (the PDP Law) adds obligations to erase and destroy data under certain conditions, and the ITE Law together with GR 71/2019 imposes comparable duties on electronic system operators.
What is the difference between Clear, Purge, and Destroy in NIST SP 800-88?
Clear uses standard logical techniques, such as overwriting, that protect against recovery with ordinary software tools. Purge uses stronger techniques — such as cryptographic erase or degaussing — so data cannot be recovered even with laboratory methods. Destroy physically destroys the media itself; the appropriate tier depends on data sensitivity and whether the media will be reused.
What does the certificate of destruction contain, and can it be used in audits?
The certificate records the media identity (make, model, serial number), the sanitization method, verification results, execution time, location, and the responsible operator and witnesses. Combined with the chain-of-custody records, it is designed as auditable evidence that can be attached to the official destruction report and presented to auditors and regulators.
What about SSDs, media in live servers, or data in the cloud?
SSDs cannot be reliably destroyed with legacy overwriting because of wear leveling, so methods such as cryptographic erase or verified built-in sanitize commands are more appropriate. For live servers, Datasan supports selective destruction per file or dataset without disrupting operations, and for cloud-resident data the approach is designed jointly, based on the controls your provider makes available.
Can destruction be performed on-site at our premises?
Yes. For highly classified data, many organizations require that media never leave their facilities, and Datasan can perform sanitization and physical destruction on-site, witnessed by your representatives. Where destruction takes place at a controlled facility, the chain of custody ensures every movement of media is recorded and accounted for.
