Data Breach
Response (Turkey KVKK)
When a data breach occurs, the clock starts. Survive the unforgiving 72-hour KVKK notification window with immediate, strategic legal intervention from our elite Turkish attorneys, protecting your operations from maximum-tier administrative fines and public relations disasters.
The 72-Hour Legal Reality in Turkey
A data breach is an operational crisis, but mishandling the regulatory notification transforms it into a highly public legal catastrophe. Under the Turkish Personal Data Protection Law (KVKK), the severity of an administrative fine is heavily influenced by how you respond in the immediate aftermath of an incident.
Attempting to suppress a breach, or delaying notification beyond the strict 72-hour window mandated by the Board, is viewed by the Authority as an aggravating factor that invariably results in the highest tier of financial sanctions.
The Threat of Public Announcement
The Turkish KVKK framework contains a unique and severe reputational risk: Public Disclosure by the Board. Under Article 12(5), once you notify the Board of a breach, the Board may officially publish the details of your breach on their public website (www.kvkk.gov.tr).
These "İhlal Bildirimi" (Breach Notification) announcements are actively monitored by the Turkish media, consumer protection groups, and competitors. How the notification form is legally drafted dictates the narrative the Board will publish.
Statutory Framework & Board Decisions
Relevant Turkish Legislation
- KVKK Law No. 6698, Article 12(5): Notification
"In case the processed data are obtained by others by unlawful means, the data controller shall communicate this to the data subject and the Board within the shortest time. Where necessary, the Board may announce such breach at its official website or through other methods." - Board Decision No. 2019/10: The 72-Hour Rule
The Board formally clarified that the phrase "within the shortest time" in Article 12 means within a strict 72-hour timeframe from the moment of awareness. - Administrative Fines (Article 18):
Fines for failing to take data security obligations (which lead to the breach) are the highest in the KVKK, often reaching the multi-million TRY statutory cap based on the Revaluation Rate.

Contact Emergency Legal CounselFrequently Asked Questions
Critical answers on Turkish breach reporting obligations.
What is the deadline to report a data breach to the KVKK Board?
Under Article 12(5) of the KVKK, and further clarified by Board Decision No. 2019/10, data controllers must notify the Personal Data Protection Board within 72 hours of becoming aware of the breach.
What happens if we miss the 72-hour KVKK deadline?
Missing the 72-hour deadline without a justifiable reason triggers severe administrative fines. You must still submit the notification immediately, accompanied by a detailed, legally sound justification for the delay.
Does the KVKK Board make our data breach public?
Yes. This is a critical feature of the Turkish system. Article 12(5) grants the Board the authority to announce the breach on its official website. The Board routinely publishes these breach notifications ('İhlal Bildirimleri'), making them visible to the media, competitors, and the public.
How do we notify the affected individuals?
The law states you must notify the data subjects 'in the shortest time possible'. If direct contact is impossible, the Board may dictate how you communicate the breach (e.g., via a prominent banner on your website or a press release).
What is the 'İhlal Bildirim Formu'?
It is the official 'Data Breach Notification Form' published by the Authority. It must be filled out meticulously. Submitting incomplete or contradictory information on this form often leads to deeper investigations into your overall Article 12 security measures.
Can we be fined even if we report the breach on time?
Yes. Timely reporting satisfies the notification obligation, but the Board will still investigate the root cause. If the breach occurred because you failed to take adequate technical and administrative measures (violating Article 12(1)), you will be fined heavily.
We are a Data Processor in Turkey. What should we do?
As a processor, you do not notify the Board directly. You must notify the Data Controller 'without delay'. The Data Controller is legally responsible for notifying the KVKK Board within the 72-hour window.
