Build a GDPR Data Map

A GDPR data map helps an organisation understand what personal data it handles, where it comes from, how it is used and where it goes. We work with relevant teams to establish a clearer picture of processing activities across systems and business processes.

We identify the personal data your organisation collects, where it comes from, which systems process it, who can access it and where it is shared or transferred. We organise these findings into a practical GDPR data map that can support wider compliance activities. The map can then be used as a working reference when processing changes, new suppliers are introduced or privacy risks need to be reassessed.

What's included

How our data flow mapping works

Data can flow widely across an organisation, so mapping those flows is crucial to identifying the risks around the visibility, transfer and sharing of data.

✓Mapping how personal data moves across your organisation
✓Identifying risks linked to the visibility, transfer and sharing of data
✓Producing a graphical data flow map, the clearest format in most cases
✓Giving you a document to retain as evidence of your understanding of your data flows
✓Feeding the map into risk assessments such as Data Protection Impact Assessments (DPIAs)

Practical GDPR Data Mapping

GDPR data mapping can identify data flows, recipients, suppliers, access points, retention arrangements and other important processing details. We help turn this information into a practical resource that supports wider data protection governance and risk management.

Our GDPR data mapping can cover personal data sources, systems, business processes, recipients, suppliers, sharing arrangements, transfers, access points and retention considerations.

Use Data Flows to Improve Compliance

A clear view of data flows can support audits, risk assessments, DPIAs and records of processing activities. By understanding how information moves through the organisation, teams can make better-informed decisions about controls, sharing and privacy.

Understanding Personal Data Flows

Our data mapping support is suitable for organisations that need greater visibility of personal data flows to support GDPR compliance, audits, risk assessments, DPIAs and wider data protection governance.

Using Data Mapping for Better Governance

We focus on creating a GDPR data map that is useful for ongoing compliance rather than simply producing a static diagram. Clear GDPR data mapping can help organisations understand processing, identify risks and support informed decisions.

From our experience

Mapping data flows for new technology

For an Irish wealth management and investment banking firm, our team documented the data flows for a new technology used to assess eligibility for its products, alongside several privacy assessments.
