GDPR Compliance Audit and Assurance Services

Demonstrate GDPR compliance through structured, evidence-driven audits that validate privacy control and uncover compliance gaps to provide credible assurance to regulators and strengthen accountability across your organization.

Why it matters

The GDPR Compliance Challenges Organizations Face

Proving GDPR Compliance to Regulators and Stakeholders

Organizations often struggle to demonstrate compliance through clear documentation, evidence, and audit-ready governance frameworks.

Fragmented Privacy Governance Across Business Units

Inconsistent policies, controls, and accountability across geographies and departments create gaps in how GDPR requirements are implemented.

Limited Visibility into GDPR Risk Exposure

Without structured assessments, organizations lack clarity on high-risk processing activities, compliance gaps, and remediation priorities.

Operational Inefficiencies in Data Subject Rights Management

Handling data access, deletion, and correction requests can become complex and error-prone without standardized processes and oversight.

Rising Customer and Partner Demand for Independent Assurance

EU-based clients and partners increasingly require demonstrable evidence of GDPR compliance through independent audits and assessments.

Gaps in Breach Response and Regulatory Notification Readiness

Many organizations lack well-defined processes to investigate, document, and report breaches within GDPR’s strict timelines.

Our Approach

Five step approach

SISA’s Risk-Driven Methodology for GDPR Compliance Assessment

We begin by defining the scope of the audit based on the organization’s data processing activities, regulatory exposure, and operational risk profile.

Relevant GDPR requirements are mapped to existing privacy controls, governance frameworks, and operational processes to establish a clear assessment baseline.

Controls are evaluated through detailed evidence validation and testing of both design and operating effectiveness across key GDPR requirements.

Identified gaps are prioritized based on regulatory risk and operational impact, with practical recommendations to strengthen compliance readiness.

A structured report provides leadership with clear insights into compliance posture, risk exposure, and actions required to strengthen GDPR compliance.
