Risk matrix: A visual tool for GDPR risk assessment

A risk matrix is a visual representation of risks that helps organizations assess and prioritize threats based on probability and impact. It is commonly used in GDPR compliance to evaluate data protection risks and implement appropriate mitigation measures.

By using a structured risk matrix, organizations can effectively identify, monitor, and address vulnerabilities in their data processing activities.

How does a risk matrix work?

A risk matrix consists of two key axes:

  • Probability (Likelihood) – The likelihood of a risk occurring.
  • Impact (Severity) – The potential consequences of the risk.

Each identified risk is assigned a score for probability and impact, then placed within the risk matrix to determine its priority level:

  • Low risk – Minimal impact and low probability.
  • Medium risk – Moderate probability or impact, requiring monitoring.
  • High risk – Significant impact or high probability, requiring urgent attention.
  • Critical risk – Severe impact and high probability, demanding immediate action.

Why use a risk matrix for GDPR compliance?

A risk matrix helps organizations:

  • Visually assess data protection risks and prioritize mitigation efforts.
  • Ensure GDPR compliance by identifying high-risk processing activities.
  • Improve decision-making with clear risk categorization.
  • Strengthen security measures by addressing critical vulnerabilities.

How to create and use a risk matrix for GDPR compliance

1. Identify risks in data processing activities

  • Conduct risk assessments to detect vulnerabilities in data collection, storage, and sharing.
  • Categorize risks based on their potential impact on data subjects.

2. Assign probability and impact scores

  • Evaluate how likely a risk is to occur (low, medium, or high).
  • Determine the severity of its impact on data protection and compliance.

3. Implement mitigation strategies based on risk level

  • Monitor low risks but take minimal action.
  • Apply security measures for medium and high risks.
  • Immediately address critical risks with strong safeguards.
