Turkey's Kisisel Verilerin Korunmasi Kanunu (KVKK), Law No. 6698, requires every organisation processing the personal data of Turkish residents to implement technical and administrative safeguards, report breaches within 72 hours, and register with the VERBIS registry. This guide maps what those obligations mean at the endpoint level, and how Zecurit Endpoint Manager helps you meet them.
The Kisisel Verilerin Korunmasi Kanunu (KVKK), officially Law No. 6698, entered into force on 7 April 2016, making Turkey one of the first countries outside the European Union to enact comprehensive personal data protection legislation. Modelled closely on the EU Data Protection Directive that preceded the GDPR, KVKK establishes a broad framework of obligations for data controllers and processors handling the personal data of Turkish residents, regardless of where those organisations are based.
Turkey's official name changed to Turkiye in 2022, recognised by the United Nations and the US State Department. The law itself remains officially titled KVKK, and enforcement is carried out by the Kisisel Verileri Koruma Kurumu (KVKK Authority, or TDPA), established as a financially and administratively independent supervisory authority in early 2017.
This guide maps KVKK's technical measure obligations to specific capabilities in Zecurit Endpoint Manager, so IT and compliance teams can translate the law's Article 12 requirements into day-to-day endpoint controls.
KVKK's obligations apply differently depending on the role an organisation occupies in the data processing chain:
The natural or legal person who determines the purposes and means of processing personal data. Controllers carry primary accountability for KVKK compliance and VERBIS registration.
A natural or legal person processing personal data on behalf of a data controller. Both controllers and processors share joint responsibility for data security under Article 12.
The natural person whose personal data is being processed. KVKK grants data subjects rights to access, rectification, deletion, restriction, and objection to automated decision-making.
The Data Controllers Registry Information System. Most organisations processing Turkish personal data must register with VERBIS and keep their records current, with changes updated within seven days.
Personal data that requires heightened protection: race, ethnic origin, political opinion, religion, health data, biometric data, genetic data, sexual life, criminal convictions, and trade union membership.
A mandatory appointment from 2025 for organisations exceeding defined thresholds in data processing volume. The DPO monitors compliance, liaises with the Authority, and serves as the contact point for data subjects.
KVKK's reach extends well beyond Turkey's borders. The law applies to:
Administrative fines under KVKK are adjusted annually by Turkey's statutory revaluation rate. The 2026 revaluation rate of 25.49% produced the following current fine ranges, effective for 2026:
| Violation | Minimum Fine (TRY) | Maximum Fine (TRY) |
|---|---|---|
| Failure to inform data subjects | 85,437 | 1,709,200 |
| Failure to fulfill data security obligations | 256,357 | 17,092,242 |
| Failure to comply with Board decisions | 427,263 | 17,092,242 |
| Failure to register with or notify VERBIS | 341,809 | 17,092,242 |
| Failure to notify SCCs for cross-border transfers | 90,308 | 1,806,377 |
KVKK's obligations for technical measures flow from six foundational data protection principles that every data controller must observe. Understanding these principles makes it easier to see where endpoint controls fit.
Personal data must be processed in accordance with law and in a fair manner. Technical controls that prevent unauthorised access directly support this principle by ensuring only lawful processing can occur.
Data must be collected for specified, explicit, and legitimate purposes and not processed in a manner incompatible with those purposes. Software inventory and device control help enforce these boundaries at the endpoint.
Only data adequate and relevant to the purpose must be collected. Controlling which applications and devices can access or store personal data is how minimisation is enforced technically.
Personal data must be accurate and, where necessary, kept up to date. Hardware and software change alerts detect configuration drift that could allow unauthorised modification of data-handling systems.
Data must be retained only as long as necessary. Remote script execution can automate scheduled data cleanup across managed endpoints, supporting retention and erasure workflows at scale.
Technical and administrative measures must be implemented to prevent unlawful processing, unauthorised access, and destruction or alteration of personal data. This is the most directly endpoint-relevant obligation in the law.
KVKK has evolved significantly since its 2016 enactment, with two rounds of amendments that materially affect how organisations manage endpoint security and personal data.
The 2025 amendments, the most significant since the law's introduction, introduced several changes with direct endpoint implications:
The following sections translate KVKK's technical measure obligations under Article 12 into the specific Zecurit capabilities that support each one.
Article 12 requires data controllers and processors to take all necessary technical measures to ensure the security of personal data. The 2025 amendments explicitly named encryption systems as a required technical measure, covering both data at rest and data in transit. An unencrypted device containing Turkish resident personal data represents a direct Article 12 violation if lost or stolen.
BitLocker Management enforces drive encryption across every managed Windows endpoint from a central console, with TPM-only, TPM+PIN, and passphrase authentication modes. Recovery keys are backed up automatically, and BitLocker Compliance Reports identify any unprotected device across the fleet, giving your DPO fleet-wide, audit-ready encryption evidence for KVKK compliance.
Organisations must ensure personal data can only be accessed by authorised personnel, and that access is governed by purpose limitation. The 2025 amendments explicitly require multi-layered authentication systems for accessing sensitive personal data, beyond simple password protection.
Configuration Management's User and Group Management lets IT teams create, modify, and disable local user accounts remotely, enforce password policy across the fleet, and audit all account changes from a central console. Remote Access sessions require explicit session confirmation from the end user and are governed by role-based access controls with full session logging, supporting both the access restriction and the accountability obligations Article 12 requires.
Article 12 explicitly requires measures to prevent unlawful processing and disclosure of personal data. Unmanaged USB drives, Bluetooth transfers, and unauthorised peripherals are among the most common routes through which personal data leaves an organisation without authorisation, and Article 12 holds both the controller and processor jointly responsible for these failures.
Device Control enforces allow, block, or trusted-only policies for removable storage, Bluetooth, wireless adapters, and Windows Portable Devices, with BadUSB keystroke injection prevention. Policies are enforced even when endpoints are offline, closing a gap that network-based controls cannot address. Every connection attempt and blocked event is logged with a timestamp and user account, building the audit trail Article 12 compliance requires.
The 2025 amendments require regular audits to evaluate compliance with data protection protocols and mandate intrusion detection capabilities. Unpatched systems are the most common vector through which attackers gain access to personal data, and regulators treat missing patches on systems holding personal data as a direct failure of Article 12's technical safeguard obligations.
Patch Management continuously scans every managed endpoint for missing patches, ranking them by CVSS score and active exploit intelligence for immediate triage. Patches deploy automatically during configured maintenance windows, and Patch Compliance Reports document remediation timelines with dated, per-device evidence. Vulnerability Management maps installed software against known CVEs, directly supporting the regular audit and security testing requirements introduced in 2025.
Following the 2025 amendments, all data breaches must be reported to the KVKK Authority within 72 hours of discovery, regardless of severity or harm threshold. A mandatory Data Breach Response Plan must be maintained. Detecting a breach quickly is the precondition for meeting the notification clock, and that detection starts at the endpoint where breaches originate.
Real-time Security Alerts flag disabled antivirus, firewall, and BitLocker protection the moment they change, rather than during a periodic scan. Device Control logs and User Logon Reports give incident response teams the forensic detail needed to scope and classify a breach quickly enough to meet the 72-hour notification window, including the nature, categories, and approximate number of affected records.
Data controllers must maintain a detailed inventory of all personal data processing activities for VERBIS registration, including the categories of data, purposes, retention periods, security measures, and the systems and devices that handle the data. This inventory is the foundation for accurate VERBIS registration and for any KVKK Authority inspection.
Hardware Inventory automatically collects specification data from every enrolled device, and Software Inventory tracks every installed application in real time with version data. This gives your DPO the complete picture of which devices and applications handle personal data across the organisation, directly feeding the data inventory that VERBIS registration and Article 10 require.
Article 12 requires technical measures to maintain data integrity and prevent alteration or destruction of personal data. The 2025 amendments emphasise proactive compliance, meaning configuration controls must be continuously enforced rather than periodically checked. Unauthorised software installations and configuration drift are both integrity risks.
Configuration Management enforces consistent security baselines across all managed endpoints, with hardware and software change alerts detecting the moment any device deviates from its approved configuration. Software Alerts notify IT teams when prohibited software is installed, and Software Licence Management ensures only authorised applications operate on devices handling personal data.
The KVKK Authority has broad inspection powers and requires data controllers to demonstrate that their technical measures were actually implemented and operational, not just documented in a policy. When the Authority investigates following a complaint or breach notification, the difference between producing a unified audit trail immediately and reconstructing fragmentary evidence over days frequently determines the outcome of the investigation.
Compliance and Reporting provides 100+ built-in report templates, including pre-mapped templates for GDPR, ISO 27001, PCI-DSS, HIPAA, CIS, and NIST. Security Reports surface BitLocker gaps, firewall status, and antivirus health across all endpoints. Scheduled Report Delivery emails these reports automatically, building a continuous, exportable compliance record that makes evidence production a matter of minutes rather than days.

The KVKK Authority's enforcement shift in 2024 and 2025, from guidance to large-scale active investigation, means that having a privacy policy is no longer sufficient. With 16,350 organisations investigated in a single month and over 500 million TRY in penalties issued, the Authority is testing whether technical measures are actually implemented and operational, device by device.
The 2025 amendments raised the bar further, explicitly naming encryption systems, multi-layer authentication, regular security audits, and mandatory Data Protection Officers as compliance requirements. These are not abstract legal concepts. They are controls that live on the endpoints where Turkish resident personal data is stored, processed, and transmitted every day.
