How to keep business documents confidential
when outsourcing admin

Outsourcing document work to an AI service raises legitimate questions about data security and confidentiality. Asking those questions before you start is exactly the right approach — and the answers should be specific, verifiable, and independently certified.

Why document confidentiality matters when using AI

Business documents often contain sensitive information — client details, financial figures, personal data, commercially sensitive content, or information subject to regulatory requirements. When you outsource document work, that information leaves your control temporarily. Understanding exactly what happens to it during that process is not optional — it is a basic due diligence requirement.

The concern is particularly relevant with AI services because many consumer AI tools — ChatGPT, Claude, Gemini — have historically used user inputs to improve their models. Sending sensitive business documents through a consumer AI tool without understanding the data policy is a genuine risk.

The risk with consumer AI tools

Consumer AI tools are designed for general use. Their data policies vary and change over time. Some use conversation data for model training by default unless users opt out. Some store conversation history in ways that are accessible to the provider. Some have data processing arrangements that do not meet UK GDPR requirements.

For business use — particularly in regulated industries like healthcare, legal, and financial services — this is not an acceptable risk. The consequences of a data breach or regulatory non-compliance are serious enough that the convenience of a consumer tool does not justify the exposure.

What to look for in an AI admin service

When evaluating any AI service for document work, five questions give you the information you need:

1
Is the service registered with the ICO? The Information Commissioner's Office is the UK's data protection regulator. Registration is a legal requirement for any organisation processing personal data in the UK. An unregistered service is not compliant with UK law.
2
Is the service GDPR compliant? Full compliance with the UK General Data Protection Regulation covers how data is collected, stored, processed, and deleted. Ask for a data processing agreement if you are sending personal data.
3
Are the systems independently certified? ISO 27001 and SOC 2 are internationally recognised security certifications that require independent audit. A service that claims security without independent certification is making an unverifiable claim.
4
Is your data used to train AI models? This is the most important question for confidentiality. If the answer is yes — or if the service cannot confirm it is not — your sensitive business information may be incorporated into a publicly accessible AI model.
5
Are public consumer AI tools used in the process? If a service processes your documents through ChatGPT or similar consumer tools, the data policies of those tools apply to your information — not just the service's own policies.

How Stratiform AI handles document confidentiality

Stratiform AI is built around the confidentiality requirements of UK businesses from the ground up. Here is how each of the five questions is answered:

ICO Registered
Stratiform AI Ltd is registered with the UK Information Commissioner's Office. Registration number available on request.
GDPR Compliant
Full compliance with UK GDPR. Data processing agreements available for clients handling personal data.
ISO 27001 & SOC 2
Every platform in our workflow is independently certified to ISO 27001 or SOC 2 standards. Certifications available on request.
No Training Data Exposure
Client data is never used to train public AI models. Your information is processed and protected — not incorporated into any shared dataset.

No public consumer tools: Stratiform AI does not process client documents through consumer AI tools. All processing occurs within a controlled, private environment. The AI systems we use operate under enterprise data agreements that prohibit training data use.

Special considerations for regulated industries

Businesses in healthcare, legal, and financial services face additional regulatory requirements around document handling. Stratiform AI works within these requirements with clearly defined boundaries:

  • Healthcare: We handle administrative documentation — care reports, referral letters, case summaries — but not clinical records, prescriptions, or data subject to specific clinical governance requirements.
  • Legal: We handle client correspondence, compliance documents, and policy formatting — but not legal advice, litigation strategy, or content requiring a practising solicitor's sign-off.
  • Financial services: We handle operational documents, reports, and correspondence — but not regulated financial advice, investment recommendations, or FCA-governed outputs.

Practical steps before outsourcing document work

Before sending any sensitive documents to an AI service, take these steps:

  • Confirm ICO registration — searchable at ico.org.uk
  • Request confirmation of GDPR compliance and ask for the data processing agreement
  • Ask which specific AI systems are used and confirm their data policies
  • Confirm that your data will not be used for model training
  • Check whether the service has a security page with certification details

Any reputable AI admin service should be able to answer all of these questions immediately. If a service cannot or will not provide clear answers, that is the answer.
