KVKK compliance in Turkey means mapping which personal data your organisation processes, why, where and for how long, then building the legal bases, privacy notices, retention rules and technical safeguards around that map. The process is not one-off paperwork: it starts with a data inventory, is enforced through access rights and logs, and stays alive through regular audits.
Key takeaways
- KVKK compliance starts with a personal data inventory; privacy notices, the retention and disposal policy and technical safeguards all rest on it.
- According to the KVKK 2025 Annual Activity Report, the Board fined 876 data controllers in 2025; 594 cases concerned VERBIS duties.
- Data subject requests must be resolved within 30 days, and breaches notified to the Board within 72 hours of becoming aware of them.
- Law No. 7499 amendments, in force since 1 June 2024, rewrote the rules on cross-border transfers and special category data.
- KVKK compliance is not a project that ends: review the inventory, access rights and policies at least once a year.
What is KVKK, and why does compliance so often stall?
KVKK is Türkiye's Personal Data Protection Law (Law No. 6698), in force since 2016 and enforced by the Personal Data Protection Authority and its Board. It is often compared with the EU General Data Protection Regulation (GDPR) and shares much of its logic: data controllers need a lawful basis, must inform people, keep data secure, answer data subject requests and report breaches. Any company with employees, customers or suppliers in Türkiye, including foreign-owned subsidiaries, is almost certainly a data controller.
Many organisations handled KVKK in 2016 by publishing a privacy notice, drafting a consent form and moving on. The real problem with KVKK compliance is that the documents never reached the systems. ID copies sit in an HR folder for years, a former employee's mailbox is still open, and the customer list lives on a shared drive everyone can reach. On paper the company looks compliant; the first complaint or breach proves otherwise.
The law has also moved on. Amendments made by Law No. 7499, in force since 1 June 2024, rewrote the conditions for processing special categories of data and the rules on cross-border transfers. Any business sending data to an overseas cloud service (see our guide to cloud migration cost and data location) or working with a foreign vendor should revisit its earlier assessment. We cover the new transfer rules and standard contract notification in detail in KVKK cross-border data transfer.
That is why KVKK compliance works best as a managed process rather than a project with an end date. If you will run compliance with outside support, how to choose the consultant is covered in our guide to choosing a data protection consultant.
What does KVKK non-compliance cost? The Board's 2025 figures
The Authority's own annual data shows that KVKK enforcement is real:
According to the KVKK 2025 Annual Activity Report, the Board imposed administrative fines on 876 data controllers in 2025: 594 for failing registration and notification duties with the Data Controllers' Registry, 142 in connection with breach notifications and 140 following complaints and reports.
The volume of complaints is rising too. The same KVKK 2025 annual report records 12,512 complaints and reports received in 2025, and 2,528 Board decisions that year. A complaint from an employee, a job applicant or a customer is now an ordinary business risk, not an exception.
Fines are only part of the picture; the breach itself is the larger cost. According to the IBM Cost of a Data Breach Report 2026, the global average cost of a data breach rose 12% to a record $4.99 million. Only 37% of breached organisations said they encrypt sensitive data both at rest and in transit (IBM 2026 press release).
Suppliers are part of the chain as well: the Verizon 2026 Data Breach Investigations Report found that breaches involving a third party reached 48% of the total. Every software vendor, payroll bureau or cloud service working without a data processing agreement adds to that risk.
What are the KVKK compliance steps? An 8-step roadmap
The KVKK compliance sequence below works for a 20-person office and for a multi-site manufacturer alike. Each step feeds the next: you cannot write a privacy notice without an inventory, or a disposal plan without retention periods. The table structure and how to pull it from your systems are covered in our personal data inventory guide, and keeping it in one source with your reporting data dictionary is explained in our data governance framework.
- Appoint owners and set the scope. Name an executive sponsor plus representatives from HR, IT, legal and sales. Record which legal entities, sites and systems are in scope.
- Build the personal data inventory. For each process, answer: which data categories, which data subjects (staff, applicants, customers, visitors, supplier contacts), what purpose, which legal basis, where it is stored, who receives it and how long it is kept. Include email, file servers, ERP, time and attendance, IP camera recordings and the licence plate recognition records at your car park gate.
- Separate legal bases from explicit consent. Asking for consent where a contract, legal obligation or legitimate interest already applies is a common mistake. Reserve explicit consent for processing that genuinely needs it; we show the distinction with examples in explicit consent vs privacy notice.
- Write privacy notices and set up a request channel. Draft a clear notice for each group of data subjects. Create a channel and workflow for data subject requests; the law requires a response within 30 days at the latest; the workflow is detailed in handling data subject requests. If you use security cameras, you also need a layered notice at the entrance; we explain how in CCTV recording and KVKK.
- Check your VERBIS obligation. Registration with the Data Controllers' Registry depends on headcount, balance sheet total and core activity; being exempt does not remove any other duty. Our VERBIS registration guide covers the thresholds, exemptions and registration steps.
- Write a retention and disposal policy. Set a retention period for each data category and the method used when it expires: deletion, destruction or anonymisation. Neglected deletion is a real source of complaints: according to the KVKK 2025 annual report, 551 applications in 2025 concerned failure to erase, destroy or anonymise data. Our data retention and disposal policy guide walks through it.
- Embed technical and organisational measures. Role-based access, multi-factor authentication, encryption, access logs, backups, same-day removal of leavers' access, processor agreements and staff training form the backbone. Add a written AI usage rule as well: staff pasting customer or employee data into public AI tools can amount to an unplanned cross-border transfer (is it safe to enter company data into ChatGPT?). The legal framework for such a rule is set out in our guide to AI and personal data protection.
- Prepare a breach response plan and an audit calendar. Under a Board decision, breaches must be notified within 72 hours of becoming aware of them, so responsibilities have to be written down in advance (our 72-hour response plan). Review the inventory, permissions and policies at least once a year.
Which document answers which question?
| Document / record | Question it answers | What triggers an update |
|---|---|---|
| Personal data inventory | What do we process, why and where? | New process, software or supplier |
| Privacy notices | What do we tell people? | Change of purpose or transfer |
| Retention and disposal policy | How long do we keep it, how do we delete it? | Legal or retention change |
| Permission matrix and access logs | Who can access it, who did? | Joiners, movers, leavers |
| Data processing agreements | How does the vendor protect it? | New service contract |
| Breach response plan | Who does what during an incident? | After a drill or reorganisation |
What are the most common KVKK compliance gaps?
Most KVKK compliance problems we find sit in the technical systems. Leavers' mailboxes and file access stay open for weeks; our article on removing email access when employees leave explains how to close them. "Everyone can see everything" becomes the default on shared folders; our file sharing permissions guide proposes a permission matrix instead.
Email piles up indefinitely; we summarise retention and access rules in email archiving and data protection. Systems that process special category data, such as fingerprint-based attendance terminals, need their own assessment, covered in biometric attendance and data protection.
Basic security hygiene is part of compliance too. Our SME cyber security checklist is a practical starting point for passwords, backups and patching; the other compliance topics are gathered in our Cyber Security & Compliance guide. If you want to turn these measures into an auditable management system, read our guide to ISO 27001 certification for SMEs.
How we run KVKK compliance at Digital Bridge
In our data protection compliance consultancy we put legal documents and systems on the same table. Because the same team builds our software and hardware, we can answer "where does this data actually live?" at server, database and application level.
- We build the inventory from the systems. Process interviews are cross-checked against databases, file servers and mail, so undocumented data flows come to light.
- We implement technical safeguards. Access control, logging and penetration testing are delivered together with our cyber security consultancy team.
- We define data ownership and quality. Who owns which table and where duplicate personal records sit is clarified through data governance and quality work.
- We build retention rules into software. Retention periods and disposal lists per document type go straight into document management system projects, and we design role-based access for staff data in HR and payroll software.
We do not sell off-the-shelf packages: after a needs analysis we provide a written proposal setting out scope, phases and cost.
Smart360: the technical side of compliance for email and files
Business email and file sharing are where personal data is most scattered. Our own Smart360 product family makes the technical steps easier in both areas:
- One identity, access removed in one action. SmartMail and SmartFiles share a single identity (SmartID); a leaver's access to every product is closed in one action, and a department change updates access across all products.
- Granular permissions. SmartMail offers nine separate permissions per mailbox; SmartFiles has eight independent rights, including read, write, delete and history, managed in one matrix. SmartMail keeps an audit log and an action history on every message.
- Data separation and encryption. Each organisation's data sits in a separate database for each product; mailbox passwords are generated by the system, stored with AES-256-GCM encryption and never handed out to staff.
- Session and link control. Sessions are listed with device details and can be ended remotely; SmartFiles download and preview links expire within minutes.
- Retention periods and personal data scanning. In SmartFiles file management a folder can carry a retention period, and documents past it are listed for the person responsible; readable documents are scanned for values such as national ID numbers, IBANs and phone numbers.
The family is not limited to email and files: SmartPass access control and attendance, which works with the same identity, automatically removes the fields linking expired access records to a person every day, and SmartMail checks every incoming email with SPF, DKIM and DMARC and quarantines suspected phishing together with the reasoning behind the decision. To buy SmartMail and SmartFiles, use the Smart360 purchase page.
Next step
One table is enough to start: list five processes that handle personal data (recruitment, payroll, sales, visitor entry, customer service) and note, for each, which system holds the data and who can reach it. Bring that table to us via our contact page; we will prioritise the gaps together and turn your compliance roadmap into a written plan with scope and phases.
