Data is arguably one of the most valuable assets driving modern businesses today, but its lifecycle must include not just collection and use, but also compliant disposal. This presents the challenge of managing vast amounts of information effectively while ensuring outdated data is securely erased or destroyed.
For small and medium businesses (SMBs), the value and validity of data held across customer profiles, transaction records, and sensitive company assets, cannot be underestimated. With rising regulatory pressure and data breaches now averaging $4.88 million per incident, secure disposal is imperative. According to IBM’s Cost of a Data Breach Report 2024. SMBs, often with limited IT resources and cash flow, are particularly vulnerable – 94% reported an incident in 2024 alone, up from 73% in 2023. Retaining outdated or irrelevant data only expands a company’s attack surface, increasing risk.
Though often used interchangeably, data destruction and erasure serve distinct purposes. When combined, they enhance security, ensure compliance and optimize resources. For SMBs balancing compliance and budget constraints, a seamless approach to data destruction and erasure can strengthen security and operational efficiency. Let’s explore how businesses can implement these processes effectively.
What is Data Destruction?
Data destruction refers to the physical removal of data storage media to ensure that any stored information cannot be recovered. As a result, any hardware is rendered completely unusable thereafter.
Data destruction can include:
- Shredding: Mechanically destroying hard drives, SSDs, or other storage devices into small pieces
- Degaussing: Using powerful magnetic fields to scramble the magnetic data on storage media
- Incineration: Burning storage devices at high temperatures until they melt or vaporize
Physical destruction methods go beyond simply resigning hardware into the trash. Hardware that’s discarded without proper destruction of data can be recovered. However, the methods above comprise some of the ways that highly sensitive information is irretrievable.
For example, when a healthcare firm disposes of old drives or servers containing patient records, the physical destruction of this hardware ensures that people cannot be identified.
Documented data destruction methods establish compliance with relevant data protection regulations and create a transparent audit trail for regulatory purposes.
What is Data Erasure?
Contrastingly, data erasure is the process of removing stored data from media or hardware without physically destroying the device. This process allows for the potential reuse, resale or repurposing of hardware.
Erasure methods include (but are not limited to):
- Secure wiping: Overwriting existing data with random undecipherable patterns multiple times
- Cryptographic erasure: Deleting the encryption keys that protect encrypted data, rendering the encrypted data unreadable
- Factory reset plus: Enhanced versions of manufacturer reset procedures with additional security measures
- Targeted data removal: Selectively removing specific files or datasets while preserving others
Data erasure methods are helpful for businesses prioritizing sustainable IT practices. Rather than discard functional hardware, erasure allows for the reuse of devices. Many SMBs – under scrutiny from evolving environmental, social and governance (ESG) regulations – are opting for electronic device reuse given the compounding electronic waste (e-waste) problem.
When upgrading company equipment, proper data erasure ensures that all stored data is completely removed before the hardware is allocated to other departments, or repurposed through approved vendors to go to other users outside the organization. For example, in 2024 alone, electronics retailer MPB reported 570,000 electrical items recirculated through its portal, indicating a clear rise in circular business practices.
Data erasure and hardware reuse extend the lifecycle of technology and reduce a business’s carbon footprint.
Similarities and Differences Between Data Erasure and Data Destruction
While data destruction and erasure are often used interchangeably and serve the same core purpose – making data unrecoverable – they differ in several key aspects.
| Issue | Data Destruction | Data Erasure |
| Hardware Integrity | Renders hardware unusable | Preserves physical device |
| Environmental | Exacerbates e-waste footprint | Promotes sustainability through reuse |
| Costs | Higher immediate cost, potential loss of asset value | More cost-effective, preserves asset value |
| Verification | Visual confirmation possible | Requires software certification |
Both data erasure and destruction processes provide irrefutable evidence of data protection, but the most appropriate solution depends on each business case. Factors such as data sensitivity and volume, hardware condition, incumbent policies, environmental goals and regulatory requirements will all need to be considered.
Benefits of Integrating Destruction and Erasure Processes
Methodically designing an integrated, aligned approach to both erasure and destruction unlocks tremendous value for businesses. Not only will they reach their goals of ultimately destroying irrelevant data, but they will also be able to discover valuable business intelligence benefits that can drive their organizations forward.
- Procurement costs: By monitoring which assets undergo erasure versus destruction, organizations can make more informed procurement decisions based on the average hardware lifecycle.
- Improved risk management: Aligning erasure and destruction processes empowers businesses to be more clued into possible risk factors.
- Regulatory compliance: Approved data erasure or destruction methods can help businesses maintain compliance with evolving industry regulations.
- Efficiency: Combining erasure and destruction processes streamlines workflows, minimizes disruption, and optimizes resources.
- ESG goals: Businesses can reuse devices in good working condition until the end of their lifecycle before they are ultimately destroyed, maximising their usage and minimizing their environmental contributions.
Considerations When Choosing Destruction and Erasure Methods
When it comes to deciding on data destruction and/or erasure methods, businesses should weigh up their decision carefully.
Not all data requires the same level of protection, so a tiered approach based on data classification may be preferable. Highly sensitive data may warrant full destruction or erasure processes, whereas publicly available or non-proprietary information may not need the same level of disposal.
For example, HIPAA requirements mandate the need for stringent data destruction and erasure processes, while others like SOX and GLBA suggest other solutions. Depending on your industry, you may not be guarded by so much red tape.
The physical state of your hardware devices and their potential reuse value must be considered. Assets that still work are better candidates for erasure, while obsolete or damaged devices would be better suited for destruction.
Cost assessments should be conducted to consider the direct upfront and long-term costs of destruction and erasure, the potential value recovered through reuse or resale, and environmental disposal costs versus savings.
Security Standards in Data Handling
It’s worth paying close attention to established security standards and frameworks to measure the effectiveness of your data disposal process(es). This includes:
- NIST (National Institute of Standards and Technology)
- DoD 5220:22-M (Department of Defense)
- ISO (International Organization for Standardization)
- PCI DSS (Payment Card Industry Data Security Standard)
- Relevant industry regulations depending on your business sector(s) of operation
How SMBs Can Navigate Changing Data Regulations
For SMBs trying to conserve resources, meet regulations and sustainability targets, and achieve their business goals, keeping pace with data protection regulations is no easy feat. To ensure you get the most out of your time and resources, it’s important to be adaptable when it comes to disposing of obsolete data and/or hardware.
- Rather than treating data destruction as a siloed process, incorporate it into a cohesive data governance strategy.
- Establish clear accountability and ownership rights for data assets and hardware.
- Implement robust access control processes to ensure only authorized personnel can access sensitive data.
- Leverage automation to reduce manual handling time and minimize the risk of human error (e.g. software that documents the chain of custody and tools that scan for obsolete data based on retention policies.)
- Consider using AI and automation tools to unlock more granular insights into your sustainability efforts and improve decision-making.
- Consider partnering strategically with third-party data erasure and destruction partners to handle physical media.
- Keep abreast of regulatory requirements and changes that may affect current processes.
- Maintain certificates of erasure and/or destruction for complete peace of mind.
- Schedule regular reviews of your data erasure and destruction processes.
- Adjust processes based on emerging technologies and recommendations.
