CPATurk Independent Audit

Digital risks are growing — compliance, assurance, and service continuity are no longer luxuries, but necessities. For financial institutions, technology is no longer just infrastructure — it’s the heart of regulation, reputation, and competitive advantage.

Our IT Audit Services portfolio offers a comprehensive perspective on the compliance, performance, and sustainability needs of all financial institutions — from banks to fintech companies, from asset management firms to brokerage houses. Every institution’s risk landscape and journey is unique. That’s why we work modularly, responding to your specific needs through six core advisory and audit modules.

Why IT Audit & IT Consulting Services?

You should invest in IT Audit and IT Consulting. Why?

1

Strong IT audits reduce surprises and increase foresight.

2

Through audits, risks can be turned into opportunities before they become problems.

3

IT audits enhance trust and ensure business continuity.

4

Because we see risks not in reports, but in the business; and we produce solutions not at the table, but in the field.

5

Because audits only become meaningful when we turn findings into action.

Here’s what we’ve consistently heard — and solved — over 20+ years in the financial industry:

No. Common Issue Our Solution Next Step
1 “We panic every time an audit begins.” Continuous monitoring + pre-audit test cycles Want to see an audit-ready demo?
2 “Regulations change faster than our processes.” Compliance calendar + early warning system Let’s plan how to stay ahead.
3 “The vendor is in the cloud, but we have no logs.” SOC 1/2/3 + access mapping Bring external risks under internal control.
4 “Our disaster plan is outdated — and unknown.” BIA + live simulation cycles Ready to stress-test your plan?
5 “Controls exist — but there’s no evidence.” Auto-generated audit trail + reporting schema Let’s make your proof visible.
6 “Our IT budget grows, but value isn’t seen.” KPI–KRI dashboards + governance boards Turn investment into visible impact.
7 “Our license file is ready — but the architecture isn’t.” Enterprise architecture + process design Let’s fast-track your licensing.
8 “We have data — but not compliance.” Data governance policies + anonymization controls Turn data from risk into strength.

How Do We Integrate These Regulations?

Our audit approach ensures alignment, efficiency, and compliance across multiple regulations:

1

Our IT audit plans align with each regulation’s defined audit frequency (often 3 years, sometimes annually) and required reporting formats.

2

For fintechs and non-bank entities developing new products (e.g., Banking-as-a-Service, Open Banking), we apply CBRT Communiqué No. 31676 and BRSA Regulation No. 31069 jointly, addressing 'API security,' 'identity authentication,' and 'outsourcing (cloud) control' requirements together.

3

We manage cross-regulation obligations (e.g., KVKK 6698 and CMB III-62.2 both require access control and log integrity) via unified audit test planning to avoid duplication.
