15. UK GDPR Security of processing requirements (Article 32)

1. Service Description

ACTINUM Limited provides independent support for meeting UK GDPR security of processing requirements under Article 32.

This service helps organisations assess whether their technical and organisational security measures are appropriate to the risks presented by their processing activities. We focus on proportionate, risk‑based security decisions that can be clearly justified to the ICO and other stakeholders.

Security of processing is a legal requirement under UK GDPR, not a technical choice.

Assumption challenged: Many SMEs believe security is purely an IT issue. Under UK GDPR, security is an organisational accountability obligation owned by leadership.

2. What This Service Delivers

This service delivers clarity on security risk and defensible security decisions.

It provides:

  • Clear assessment of security risk linked to processing activities
  • Proportionate security controls aligned to risk, not size
  • Justification of what is considered “appropriate security”
  • Reduced likelihood and impact of data breaches
  • Stronger evidence for regulators and auditors

Appropriate security under UK GDPR is risk‑based, not size‑based.

3. How ACTINUM Limited Helps

ACTINUM Limited supports organisations by:

  • Assessing security risk arising from personal data processing
  • Reviewing technical and organisational security measures
  • Advising on access controls, data protection, and resilience
  • Supporting alignment between security controls and processing risk
  • Challenging assumptions about what is “sufficient” security
  • Supporting documentation of security decisions
  • Advising on improvements where gaps are identified
  • Supporting leadership understanding of security obligations

Security measures must be appropriate to the risk posed to individuals.

4. Who This Service Is For

This service is particularly relevant for:

  • UK SMEs unsure whether security controls are adequate
  • Organisations handling sensitive or large volumes of personal data
  • Businesses using cloud platforms or remote access
  • Organisations relying on third‑party service providers
  • Regulated organisations subject to scrutiny
  • Senior leaders accountable for breach risk
  • Boards seeking assurance on security posture

Security obligations apply regardless of organisation size.

5. Common Triggers for This Service

Organisations typically require this service when they are:

  • Unsure whether current security controls are appropriate
  • Reviewing security following a data breach or near miss
  • Introducing new systems or cloud services
  • Allowing increased remote access
  • Preparing for audits or regulatory engagement
  • Responding to customer or partner security concerns

Weak security controls are a common cause of reportable breaches.

6. Outcomes For Your Organisation

  • Clear understanding of security risk
  • Proportionate and defensible security controls
  • Reduced likelihood and impact of data breaches
  • Improved alignment with ICO expectations
  • Stronger evidence during audits or investigations
  • Greater confidence for senior leadership and boards

Well‑justified security decisions reduce enforcement risk.

7. Our Independence Matters

Independent & Business Aligned Advice

ACTINUM Limited provides independent, non-product led business advice, and hands-on pragmatic support.

We do not focus on selling software, platforms, or technology solutions. This allows us to act as a trusted, objective challenge to vendor claims, internal assumptions, and assurance statements and programme decisions.

8. Common Questions

What does “appropriate security” mean under UK GDPR?

It means security measures that are proportionate to the risks posed by the processing, considering likelihood and severity of harm.

Do SMEs need the same security as large organisations?

No. Security must be appropriate to risk, not organisation size.

Is encryption always required?

Not always. Controls must be selected based on risk and context.

Does using cloud services meet security requirements automatically?

No. Organisations remain accountable for security even when using suppliers.

Can ACTINUM Limited review existing security controls?

Yes. We regularly review and assess existing security measures against UK GDPR expectations.
