How to Vet a Scanning Provider for GDPR Compliance
If your documents contain any personal data — names, addresses, dates of birth, financial details, health information, employment records — your scanning provider is a data processor under GDPR. As the data controller, you are legally responsible for ensuring that processor handles data lawfully, securely and in compliance with the regulation. Simply choosing a cheap provider and hoping for the best is a compliance failure.
What GDPR Requires of a Data Processor
Under Articles 28 and 32 of the GDPR, a data processor must:
- Process personal data only on documented instructions from the controller (you)
- Ensure all staff processing data are bound by confidentiality obligations
- Implement appropriate technical and organisational security measures
- Not engage sub-processors without your prior written authorisation
- Assist you in responding to data subject rights requests (subject access requests, erasure requests)
- Delete or return all personal data at the end of the contract
- Make available all information necessary to demonstrate compliance
- Allow and contribute to audits and inspections
These are not optional — they are legal requirements. A scanning provider that cannot demonstrate compliance with these requirements is not a suitable processor for personal data.
The Data Processing Agreement
A Data Processing Agreement (DPA) is mandatory under GDPR Article 28(3). The DPA is a legally binding contract between you (controller) and the scanning provider (processor) that must specify:
- Subject matter and duration: What data is being processed and for how long
- Nature and purpose: The scanning project specifics — what documents, what output
- Types of personal data: Names, financial data, health data, etc. — be specific
- Categories of data subjects: Employees, customers, patients, etc.
- Controller’s obligations and rights: Your right to instruct and audit
- Processor’s obligations: Security measures, confidentiality, sub-processor restrictions, breach notification, data deletion
Ask for the provider’s standard DPA before signing any contract. Review it against GDPR requirements — a template that simply states “we comply with GDPR” is not sufficient. The DPA should contain specific, detailed provisions.
Technical and Organisational Measures
GDPR Article 32 requires appropriate security measures. For a scanning provider, this means specific controls you should verify:
Technical Measures
- Encrypted storage for scanned files (AES-256 or equivalent)
- Encrypted data transfer (SFTP, TLS 1.2+, encrypted media)
- Access controls — staff can only access projects they are assigned to
- Firewalls, anti-malware and intrusion detection on all systems handling data
- Regular security patching and vulnerability management
- Secure backup with encryption
- Audit logging — recording who accessed what data and when
Organisational Measures
- DBS-checked staff with confidentiality agreements
- Regular data protection training — documented and refreshable
- Physical security — restricted access, CCTV, secure document storage
- Documented information security policies and procedures
- Incident management and breach response process
- Clear desk and clear screen policies
- Secure disposal of waste paper (cross-cut shredding minimum)
Breach Notification
Under GDPR Article 33, if a personal data breach occurs, you must notify the ICO within 72 hours. This means your scanning provider must notify you even faster — ideally within 24 hours — so you have time to assess the breach, determine whether notification is required and prepare the report.
Check that your provider’s breach notification process includes:
- A defined internal process for identifying and escalating potential breaches
- A commitment to notify you within a specific timeframe (24-48 hours)
- A description of what information they will provide: nature of the breach, data affected, number of records, likely consequences, measures taken
- Named contacts on both sides for breach communication
Where Data Is Stored
GDPR restricts transfers of personal data outside the European Economic Area (EEA). Ask:
- Where are your servers physically located? UK or EU data centres are simplest for compliance
- Do you use any cloud services that might store data outside the EEA?
- Are backups stored in the same jurisdiction?
- If you use sub-processors, where are they based?
If the provider stores data outside the EEA, they need appropriate safeguards in place — Standard Contractual Clauses, adequacy decisions, or other approved mechanisms. For most UK scanning projects, the simplest approach is to use a provider whose infrastructure is entirely UK-based.
End of Contract
GDPR requires that processors delete or return all personal data when the processing is complete. Verify:
- The DPA specifies what happens to data at contract end — deletion or return
- There is a defined retention period after project completion (typically 30-90 days for QA), after which all data is securely deleted
- The provider will confirm deletion in writing
- Deletion includes backup copies, not just primary storage
- If physical documents are being retained or destroyed, the process and timeline are documented
How to Verify Claims
Providers will tell you they are GDPR compliant. Verification requires evidence:
- ISO 27001 certificate: Ask for a copy and check the certification body is UKAS-accredited. Verify the scope covers their scanning operations, not just their head office
- DPA review: Read it properly — does it address all Article 28(3) requirements?
- Facility visit: See the physical and technical controls in person
- Training records: Ask for evidence of staff data protection training
- Audit rights: The DPA should give you the right to audit — exercise it, or at least confirm the right exists
- References: Ask for references from organisations in regulated sectors (healthcare, legal, financial) who have vetted the provider’s compliance
