chain of custody Archives

Compliance audits are critical checkpoints for organizations that handle sensitive data, particularly those in the government, finance, healthcare, and other highly regulated sectors. These audits verify that your data security practices meet the standards laid out by applicable laws and frameworks—from NIST 800-88 to NSA/CSS standards.

At Security Engineered Machinery (SEM), we specialize in helping both federal and commercial clients navigate this increasingly complex space with confidence (and in compliance).

Critical Shreds

Audits focus on media sanitization. Compliance regulators want documented proof that data-bearing devices are properly destroyed.
NSA-level destruction is best. SEM recommends that physical destruction to NSA/CSS specs for all end-of-life media.
Documentation and training are non-negotiable. Staff must understand and follow stringent destruction and chain-of-custody protocols.
Equipment must be regularly maintained and serviced. Malfunctioning solutions can greatly jeopardize compliance.

Understanding Compliance Audits in Data Security

The first step is understanding what a compliance audit is and what it entails. A compliance audit is a formal evaluation that is conducted to ensure that an organization’s data handling and destruction policies align with relevant industry regulations or government requirements. For federal agencies, this typically involves ensuring strict adherence to NSA/CSS specifications for physical destruction of classified media. In the commercial space, however, there’s more variation depending on the organization’s sector:

HIPAA (Health Insurance Portability and Accountability Act) for healthcare data
GLBA (Gramm-Leach-Bliley Act) for financial institutions
PCI DSS (Payment Card Industry Data Security Standard) for organizations handling cardholder data
GDPR (General Data Protection Regulation) for companies handling EU citizens’ personal data

A critical aspect of these audits is media sanitization, also known as the process of securely destroying data storage devices (HDDs, SSDs, optical, etc.) to ensure that the end-of-life information is irretrievable. According to NIST 800-88, organizations are required to “sanitize” end-of-life media by either clearing, purging, or destroying it, depending on the confidentiality of the information. However, at SEM, we believe all end-of-life media should be physically destroyed to the NSA standard as it enforces the highest level of security, ensuring that the data is forever irretrievable.

Common Questions During a Decommissioning Audit

Given the increasing use of digital data storage devices, auditors are increasingly focusing on how organizations manage the destruction of HDDs, SSDs, optical media, and other forms of e-media. Some typical questions you can expect during a compliance audit include:

How are your HDDs, SSDs, and other media destroyed?
Where is your media destroyed?
Who has access to sensitive data, and how is it managed and recorded?
Do your destruction methods align with NSA or NIST regulations?
Are you using NSA/CSS EPL-listed equipment?
Do you maintain a verifiable chain of custody for media from when deemed end-of-life through destruction?
Can you provide documentation or logs to prove destruction was successful?

It’s important to note that these are not just technical questions—they’re legal and compliance concerns. Failing to answer them adequately can result in penalties, failed audits, or even breaches of contractual or legal obligations.

Chain of Custody and Documentation Tools

One of the biggest audit pain points is chain of custody. Auditors seek out clear evidence that from the moment a data-bearing device is taken out of service to its final destruction, every step in its handling was secure, documented, and tamper-proof. This means being able to track who accessed the device, where it was stored, how it was transported, and when destruction occurred.

Without this level of visibility and efficiency, organizations risk non-compliance, even if the destruction itself was performed properly. Documentation tools are equally critical, providing time-stamped records, asset identifiers, and confirmation that destruction was completed in accordance with policy. These records serve as proof that data disposal practices are efficient in meeting legal and regulatory standards and are often a required component of audit submissions.

Inconsistent documentation or missing data can result in audit findings, fines, or legal exposure, especially under regulations with strict accountability clauses like HIPAA, GLBA, and GDPR. And if the data is classified or top-secret? The repercussions of a breach or leak could threaten national security.

Training and Education

An effective data destruction program goes beyond having the right hardware. It includes understanding how and when to destroy assets, how to properly handle materials, and how to educate internal stakeholders. This makes training and education essential elements of a compliant data destruction program. Personnel must be familiar with regulatory standards such as NIST 800-88 and NSA/CSS specifications, and they must know how to identify, handle, and process media that is at the end of its life.

When staff are unclear on chain of custody procedures or destruction protocols, it can lead to inconsistent practices and gaps that auditors will quickly notice. Proper education helps ensure that processes are applied uniformly across departments and locations, reducing the risk of human error. It also fosters a culture of accountability where employees are empowered to follow and improve secure data handling practices. Ultimately, a well-trained team is one of the strongest defenses against audit failures and regulatory penalties.

Preventive Maintenance and On-Site Support

Nothing derails an audit faster than non-functioning equipment. Even if all policies are followed and documentation is complete, malfunctioning or poorly maintained equipment can gravely jeopardize compliance.

Preventive maintenance plays a key role in ensuring that shredders, crushers, degaussers, and other systems operate within the performance standards required by applicable regulations. Over time, even high-quality equipment can drift out of spec, potentially rendering data destruction incomplete or noncompliant. Regular inspections, service schedules, and performance testing help confirm that destruction methods remain effective and verifiable.

Additionally, having access to timely on-site support can prevent operational delays during critical periods, such as audit windows or large-scale decommissioning events. Properly maintained equipment not only protects the integrity of the destruction process but also demonstrates to auditors that the organization takes its compliance responsibilities seriously.

The Bottom Line

Compliance audits don’t need to be stressful—especially when it comes to data destruction. With regulatory scrutiny on the rise, particularly in light of growing cybersecurity threats and data breaches, it’s never been more important to ensure your media sanitization and chain of custody practices are airtight.

When compliance is on the line, SEM has your back.

As technology evolves at a relentless pace, organizations are continually refreshing their IT infrastructure to stay competitive, secure, and efficient. But with the excitement of onboarding new systems comes a less glamorous yet equally critical task—retiring outdated IT equipment. This phase is often overlooked or rushed, leading to significant security, compliance, and environmental risks. Retiring IT assets isn’t just about unplugging and discarding them; it requires a thoughtful, documented, and secure process.

Here are five common mistakes companies make when retiring IT equipment, and how to avoid them.

Assuming Data Is Gone After Deletion

Perhaps the most pervasive and dangerous misconception is that data is permanently erased simply by deleting files or formatting hard drives. In reality, deletion simply removes the pointers to data, not the actual data itself. Without proper data sanitization protocols, sensitive corporate or customer information can still be recovered using forensic tools—even from devices that appear “clean.”

To prevent this, organizations must implement certified data destruction processes that meet or exceed standards such as NIST 800-88 or NSA, depending on the industry and classification of the data being destroyed. This can involve physical destruction, such as shredding, crushing, or disintegrating, and degaussing. However, if the drive contains classified information, it should be degaussed then physically destroyed, per the NSA. This two-way destruction method ensures complete and total obliteration.

Proper documentation should include both the data’s chain of custody and the destruction process. It’s also important to retain certificates of destruction for auditing purposes. Relying on basic deletion is a gamble no organization should take, especially with data privacy regulations tightening worldwide.

Overlooking Nontraditional Data Sources

When thinking about data-bearing equipment, organizations typically focus on obvious items like servers, desktops, or laptops. However, nontraditional data sources often fall through the cracks. Devices such as printers, copiers, VoIP phones, network switches, external hard drives, and even smart devices can store sensitive configuration data, credentials, or internal communications.

The root cause of this oversight is often a lack of a comprehensive IT asset inventory. Without knowing exactly what equipment exists and what data it might contain, companies risk leaving information behind during decommissioning. Creating and maintaining a detailed asset inventory—updated continuously throughout the hardware lifecycle—is essential. It allows for thorough tracking and ensures every device is accounted for, assessed for data sensitivity, and handled properly during retirement.

Not Verifying E-Waste Recyclers

Environmental responsibility is an increasingly important part of corporate social governance, and most businesses strive to dispose of retired IT assets through recycling partners. However, not all e-waste recyclers operate ethically or securely. Some may claim to responsibly dispose of electronics but instead export hazardous waste to developing countries or improperly dispose of data-bearing devices, creating significant brand and legal risks.

Due diligence is critical when selecting a recycling partner. Look for certifications such as R2 (Responsible Recycling) or e-Stewards, which ensure adherence to high environmental and data security standards. Auditing the recycler’s practices, requesting references, and visiting their facilities when possible can also help verify their legitimacy. Partnering with a reputable recycler protects both your company’s reputation and the planet.

Delaying Decommissioning

Outdated or unused IT assets often sit idle in storage closets, server rooms, or even employee homes for extended periods. This delay in decommissioning can create a host of problems. Unsecured, unused devices are prime targets for data breaches, theft, or accidental loss. Additionally, without a timely and consistent retirement process, organizations lose visibility into asset status, which can create confusion, non-compliance, or unnecessary costs (like continued software licensing or maintenance).

The best way to address this is by implementing in-house destruction solutions as an integrated part of the IT lifecycle. Rather than relying on external vendors or waiting until large volumes of devices pile up, organizations can equip themselves with high security data destruction machinery—such as hard drive shredders, degaussers, crushers, or disintegrators—designed to render data irretrievable on demand. This allows for immediate, on-site sanitization and physical destruction as soon as devices are decommissioned. Not only does this improve data control and reduce risk exposure, but it also simplifies chain-of-custody tracking by eliminating unnecessary handoffs. With in-house destruction capabilities, organizations can securely retire equipment at the pace their operations demand—no waiting, no outsourcing, and no compromise.

Failing to Establish a Chain of Custody and Involve Compliance Teams

Retiring IT equipment isn’t just a logistical or technical task—it’s also a matter of governance and accountability. Many organizations fail to establish a documented chain of custody when IT assets are moved, stored, or handed off to third-party vendors. This lack of visibility and traceability increases the risk of data loss, theft, or mishandling.

Furthermore, failure to involve compliance, legal, and security teams in the decommissioning process can lead to overlooked regulatory obligations or missteps. In industries governed by HIPAA, GDPR, PCI-DSS, or similar regulations, improper data disposal can result in hefty fines and reputational damage. In the government sector, improper disposal can result in far worse scenarios, such as the leak of classified national secrets.

To avoid this pitfall, organizations must formalize their decommissioning policies and workflows. This includes tagging each asset, tracking its movement through every stage of decommissioning, and involving all relevant stakeholders. A documented chain of custody ensures accountability and supports audits or investigations, should they arise. Including compliance and security teams in the planning stages helps identify applicable regulations and ensures proper adherence from start to finish.

Why In-House, High-Security Data Destruction Matters More Than Ever

All of the above mistakes share a common theme: a lack of control. The more hands data passes through, the higher the risk of exposure. That’s why in-house high-security data destruction is not only a best practice—it’s becoming a necessity.

By investing in high security data destruction solutions that are designed specifically for in-house data destruction, companies maintain full custody of their data from start to finish. Physical destruction solutions such as NSA/CSS-listed disintegrators, degaussers, and hard drive shredders allow businesses to render data unrecoverable before any asset leaves the premises. This eliminates the reliance on third-party vendors, reduces the risk of chain-of-custody failure, and reinforces compliance with the most stringent data protection regulations.

Moreover, in-house solutions offer operational flexibility and peace of mind. Assets can be destroyed immediately, in a controlled environment, by trained staff—ensuring sensitive data never leaves corporate oversight. For sectors like defense, healthcare, finance, and critical infrastructure, this level of control isn’t just helpful—it’s essential.

Organizations that take data destruction seriously are recognizing that outsourced convenience doesn’t always equal security. As threats to information security become more sophisticated, the safeguards must follow suit. Security Engineered Machinery’s (SEM) data destruction equipment is a proactive investment in compliance, reputation, and operational integrity.

In the end, how an organization disposes of its IT assets says just as much about its values as how it deploys them. When the goal is to protect data at every stage of its lifecycle, the most secure option is the one that never lets it out of your sight.
