CPATurk Independent Audit

It’s not enough for everything to seem right. You need to prove it. In today’s financial sector, success is not judged solely by outcomes—but also by process, traceability, and evidence.

Auditability of digital operations, regulatory compliance, and assurance reporting are no longer “nice-to-have”—they’re the new baseline. Moreover, compliance obligations apply not only to your organization but also to affiliates, external service providers, FinTech partners, and vendors.

2. Audit & Control Framework Design for IS

Systems are only as strong as their auditability:

  • Establishment or enhancement of internal control frameworks
  • Testing of key IS controls (audit trails, access management, logging, etc.)
  • Definition of regulation-specific IS control sets
  • Test scenario design in coordination with audit functions
  • Setup of automation, monitoring, and reporting tools

3. Assurance Reporting & International Standards Alignment

Compliance is not enough—you need to demonstrate it:

  • Service assurance audits under GDS 3402, ISAE 3402, SOC 1/2/3
  • Custom assurance reports via GDS 3000, ISAE 3000
  • Alignment with frameworks like ISO 27001, ISO 22301, ISO 31000, ISO 38500, COBIT, CMMI, TOGAF, ITIL
  • Analysis of IS requirements under SOX, Euro-SOX, J-SOX
