Information technology and cybersecurity law has recently acquired a rapidly maturing regulatory framework in Turkey. Law No. 7545 on Cybersecurity, which entered into force in 2025, is the first comprehensive legislation in this field and has imposed comprehensive obligations on public institutions, private sector entities, and critical infrastructure operators. The field is shaped at the intersection of Law No. 5651, Turkish Penal Code provisions on information technology crimes, the data security framework of the Turkish Data Protection Law (KVKK), Communications Law (BTK) regulations, and sectoral technical standards. Our firm possesses the technical and legal reading discipline to simultaneously manage this multi-layered regime.

We provide our clients with support in designing cybersecurity policies and procedures, preparing incident response plans, managing content provider, hosting provider, and access provider obligations under Law No. 5651, and preparing defense strategies in parallel BTK and BTK-KVKK processes. We conduct the legal aspects of root cause analysis, evidence preservation, and insurance and supplier indemnification proceedings following cyber incidents. In information technology crimes such as unauthorized system access, data interference, fraud, and identity impersonation, we represent our clients at the complaint, intervention, and — when company employees are defendants — defense stages.

Our practice concentrates particularly on SaaS and cloud service providers, marketplace and platform operators, financial technology companies, and digital media ecosystems that process intensive personal data. Our workflows are frequently structured in coordination with our data protection team; a single cyber incident may trigger both the 72-hour authority notification obligation and, where necessary, notification to the Office of the Chief Public Prosecutor. Security addenda in cloud service agreements, supplier risk management, and BTK-compliant log retention architecture are areas on which we work regularly.

Cybersecurity is a field in which legal compliance cannot be disconnected from technical reality. Our firm works in direct coordination with our clients' information security teams; we align policy documents with applicable control points from ISO/IEC 27001 and NIST frameworks. We closely monitor the implementation timeline of secondary regulations expected under the new Law No. 7545 and the enforcement trends of the Cybersecurity Authority, providing our clients with regular information flows.
