1. Service Description
ACTINUM Limited provides independent data breach and incident management support for UK organisations.
This service helps organisations respond calmly and defensibly to suspected or confirmed personal data breaches. We support timely assessment, decision‑making, notification, and documentation in line with UK GDPR and ICO expectations.
Effective breach management is a legal and accountability requirement under UK GDPR.
Assumption challenged: Many SMEs believe breaches only involve cyber attacks. In practice, most reportable incidents arise from human error, supplier issues, or process failures.
2. What This Service Delivers
This service delivers clear breach decisions, reduced regulatory exposure, and controlled incident response.
It provides:
- Rapid clarity on whether an incident constitutes a personal data breach
- Defensible decisions on ICO and data subject notification
- Structured documentation aligned with regulator expectations
- Reduced escalation, confusion, and reputational damage
- Improved readiness for future incidents
Not all incidents require ICO notification, but all require assessment and documentation.

- Assessing suspected or confirmed data protection incidents

- Evaluating risk to individuals’ rights and freedoms

7. Our Independence Matters
Independent & Business Aligned Advice

8. Common Questions
What counts as a personal data breach under UK GDPR?
A personal data breach involves accidental or unlawful loss, destruction, alteration, unauthorised disclosure of, or access to personal data.

Where notification is required, the ICO must be informed within 72 hours of awareness.
Do SMEs have the same breach obligations as larger organisations?
Yes. UK GDPR breach requirements apply to organisations of all sizes.
