How we support you
Privacy and data protection requirements are embedded in business processes, technology, supplier relationships, and information security controls.
Independent audits help organisations understand whether privacy governance, data protection management systems, and processing controls are designed appropriately and operating effectively.
Assessments can focus on entire data protection management systems, selected processing activities, business units, suppliers, applications, or specific regulatory obligations.

Why Halderstone
Our approach
Audit planning informed by risks, objectives, and the intended use of audit results
Audit activities aligned with recognized auditing principles and guidance, including ISO 19011 where appropriate
Findings based on objective evidence obtained through interviews, documentation review, observation, and sampling
Conclusions supported by corroboration across multiple evidence sources and audit methods
Practical reporting focused on decision-making, assurance, and continual improvement
What we deliberately do not do
Mandates that compromise auditor independence
Audit engagements where we influence the selection of samples, evidence, or interview partners
Conclusions based solely on interviews without corroborating evidence
