Why Is Data Security So Important?
In the digital age, data has become the most valuable asset of businesses. However, protecting this valuable asset is both a legal obligation and the foundation of customer trust. Data breaches can cause companies millions in financial damage and hard-to-repair reputation loss.
At BUZ Yazılım, since 2007, we have kept data security as the top priority in all software projects we develop. We provide KVKK-compliant solutions to over 100 clients.
What Is KVKK?
The Personal Data Protection Law (KVKK), which came into effect on April 7, 2016, is Turkey's fundamental data protection legislation that regulates the processing of personal data. It has a parallel structure with the European Union's GDPR (General Data Protection Regulation).
Fundamental Principles of KVKK
The fundamental principles that must be followed when processing personal data:
- Compliance with law and good faith: Processing data based on a legal foundation
- Accuracy and being up-to-date: Keeping data accurate and current
- Processing for specific, explicit, and legitimate purposes: Clearly defining the processing purpose
- Being relevant and limited to the purpose: Collecting only necessary data
- Retention for the required period: Deleting data when its purpose no longer exists
Types of Personal Data
Personal data under KVKK is divided into different categories:
General Personal Data
