CPATurk Independent Audit

Your critical service may be outsourced — but the responsibility is still yours. Outsourcing in the financial sector is rapidly increasing: Cloud services, SaaS platforms, software developers, external data centers, third-party support providers…

Yet every external service introduces operational, financial, or reputational risk. And the regulation is crystal clear: Even if the service is outsourced, the control must remain in-house.

What We Do

Through our Information Systems Supplier Risk & Governance Services, we strengthen your vendor relationships with a governance model that is transparent, auditable, and sustainable.

1. Supplier Asset & Risk Analysis

The first step is to make hidden risks visible:

  • Classification of IS third-party vendors (critical / non-critical)
  • Analysis of vendors’ operational processes and systems access
  • Risk profiling across operational, cybersecurity, and legal dimensions
  • Mapping of dependencies and embedded risks between your company and its vendors
  • Identifying vendors subject to audit obligations under regulations

2. Supplier Governance Model

External services can be managed with internal-level discipline:

  • Governance framework aligned with supplier lifecycle (selection, approval, monitoring, renewal)
  • Definition of SLAs, KRIs, KPIs, audit rights, and assurance mechanisms
  • Integration of strategic and regulatory clauses into contracts (access, continuity, security, exit terms)
  • Dedicated monitoring and evaluation frameworks for critical suppliers

3. Performance, Assurance & Sustainability

An unmanaged supplier isn’t just a cost—it’s a risk:

  • Monitoring dashboards and performance indicators for suppliers
  • Periodic evaluation meetings and structured feedback processes
  • Reviewing business continuity and disaster recovery plans from the supplier’s perspective
  • Continuity scenarios in the event of vendor transition or termination
  • Compliance checks aligned with BRSA, CMB, CBRT, MASAK regulations
  • If required, conducting independent assurance audits aligned with GDS 3402, ISAE 3402, SOC 1/2/3 for critical service providers
