T\u00fcrkiye\u2019s data protection and cybersecurity regimes have evolved rapidly. The Personal Data Protection Law (No. 6698, \u201cKVKK\u201d) \u2013 in force since 2016 \u2013 is now being amended to align more closely with the EU\u2019s GDPR. As of June 2024, new legal grounds for processing \u201cspecial categories\u201d of data (including health, race, religion, etc.) have been added, mirroring GDPR provisions. For example, employers can now process employee health data without explicit consent when required by law (such as disabled employment requirements). Overall, the recent KVKK reforms broaden lawful bases for sensitive data and ease restrictions on cross-border transfers, indicating a clear trend toward GDPR-style regulation. In practice, organizations should review and update their data inventories, consents and privacy notices to reflect these changes and ensure that any processing of sensitive personal data is backed by the newly permissible legal bases.<\/p>\n\n\n\n
Turkish law explicitly requires data controllers to adopt \u201call necessary technical and organisational measures\u201d to protect personal data. While no single encryption standard is mandated, guidelines emphasize strong security frameworks. For instance, Turkish regulators have recommended that large-scale data controllers implement advanced measures \u2013 including recognised encryption methods for data in transit and at rest \u2013 especially when handling sensitive or health-related information. Sectoral rules reinforce this: healthcare providers must use encrypted channels (e.g. the KamuNet network) for medical data, and recent advisories urge encryption and multi-factor controls for cloud storage of personal data. In short, deploying robust encryption and related cyber-hygiene practices is considered best practice under KVKK security obligations, even if not spelled out as a specific \u201cencryption law.\u201d<\/p>\n\n\n\n
Under KVKK, certain organizations must register in T\u00fcrkiye\u2019s Data Controllers\u2019 Registry Information System (VERB\u0130S). Domestic controllers exceeding thresholds (over 50 employees or a TRY 100\u202fmillion balance sheet) or processing special personal data must register, and all<\/em> foreign controllers processing Turkish data are likewise required to register. Notably, any company transferring Turkish personal data abroad is deemed a Turkish data controller and must meet VERB\u0130S obligations. The hard deadline for initial registration (31 Dec 2021) has passed, and regulators now rigorously enforce compliance. Companies that register late or fail to register face steep fines for each year of delay. For example, even a foreign firm with a single employee in T\u00fcrkiye and no direct commercial activity was recently fined for a two-month registration delay.<\/p>\n\n\n\n Enforcement trends underline the need for vigilance: the Turkish DPA has begun publishing breach notices and levying substantial penalties. As of a recent report, the Authority received over 1,300 breach notifications and imposed roughly TRY\u202f463.8\u202fmillion (about \u20ac13.3\u202fmillion) in administrative fines on violators. The fine schedule has also been updated \u2013 in 2025 the maximum penalty for failing security obligations or registration is around TRY\u202f13.6\u202fmillion (approximately \u20ac700,000). Companies operating from the UK or USA with any Turkish data exposure (employees, customers, cloud storage, etc.) should immediately verify VERB\u0130S registration. Given the regulatory focus, failure to comply with VERB\u0130S now brings compounded risks (registration plus data transfer violations).<\/p>\n\n\n\n T\u00fcrkiye\u2019s cross-border data transfer rules have historically been strict. Under KVKK Article\u202f9, transfers are allowed only with explicit data subject consent or if one of the KVKK legal grounds applies in a country where an adequacy decision is in place. Since Turkey has not yet declared any country \u201csafe\u201d via adequacy decisions, and historically few undertakings were approved, many companies relied on consent. However, the March 2024 amendments (effective June 2024) significantly liberalized the framework. New provisions allow transfers if based on valid legal grounds and<\/em> one of several safeguards is met: an adequacy decision (if adopted in future), binding corporate rules (BCRs) approved by the Turkish authority, or a standard data transfer agreement published by the authority. In practice, the \u201cstandard agreement\u201d mechanism functions like GDPR\u2019s standard contractual clauses: companies can execute the model contract and simply notify the DPA within five business days (no prior permission needed).<\/p>\n\n\n\n Aside from these structured mechanisms, the law still permits occasional transfers in specific cases (e.g. explicit informed consent, contractual necessity, vital interests). Notably, the legal amendments introduced a short transition: consent-based transfers that were in place before 1\u202fJune\u202f2024 remain valid until 1\u202fSeptember\u202f2024. After that date, companies must rely on the new safeguards. Non-compliance has consequences: even routine transfers now require a formal legal basis and in many cases a notification to KVKK. For UK\/US firms, this means that simply using \u201cadequate privacy protections\u201d is not enough \u2014 one must use an approved transfer tool. In summary, post-2024, cross-border transfers require one of the Article\u202f9 safeguards, and using the standard contracts or BCRs demands notifying the KVKK, while ad hoc transfers can only occur under limited exceptions.<\/p>\n\n\n\n KVKK imposes strict breach reporting duties. Data controllers must notify the KVKK Authority \u201cwithin 72 hours of becoming aware\u201d of a personal data breach. In addition, affected individuals should be informed \u201cwithin a reasonable time\u201d. These requirements are codified in the law and reinforced by a DPA Board decision (2019) mandating that controllers have an incident response plan and clear notification procedures. In practice, companies should prepare a written breach-response protocol, conduct timely impact assessments, and file reports to the Authority promptly.<\/p>\n\n\n\n Failure to comply carries penalties. For example, not notifying the Authority can trigger fines under Article\u202f18 of KVKK: the maximum fine for neglecting security or reporting duties is in the millions of lira. Enforcement data show this is taken seriously: hundreds of breach reports have been made public, and high-profile fines (totalling over TRY\u202f460\u202fmillion) have been imposed on errant controllers. In one notable case, a large company was penalized for delayed breach notification. By contrast, firms with mature compliance programs have avoided sanction by demonstrating swift notification and mitigation. International businesses should therefore build breach response drills and ensure their Turkish operations include notification checklists, mirroring GDPR-style requirements to reduce liability.<\/p>\n\n\n\n Beyond data protection, T\u00fcrkiye regulates the use of encryption in communications. Under the Electronic Communications Law (No. 5809) and implementing regulations, entities that produce or provide encrypted communication services (such as secure messaging platforms, encrypted telecom equipment, etc.) must comply with BTK (the communications regulator) rules. A specific regulation (\u201cPrinciples on Coded or Encrypted Communications\u201d) requires service providers to notify BTK and furnish technical details about their encryption systems. Importantly, distributing encryption without authorization is penalized: violators can face jail terms (roughly 500\u20131,000 days) and administrative fines up to 3% of annual revenue. (These sanctions derive from Article 10 of the Encryption Regulation and Articles 60\u201363 of Law 5809.)<\/p>\n\n\n\n For most businesses handling data (outside of telecom operators), the electronic communications rules mean that any product or service offering end-to-end encryption must be carefully vetted. For example, if a U.S. software firm wishes to launch an encrypted messaging app in T\u00fcrkiye, it must register the app with BTK and provide required keys \u2013 otherwise it risks legal exposure. That said, simply using strong encryption for data security is not prohibited; rather, the law seeks to ensure government access capabilities. In fact, Turkish data protection guidance advises companies to use encryption as a core security measure: regulatory recommendations for sensitive data explicitly encourage \u201cinternationally recognised encryption programs\u201d and cryptographic protection of cloud-stored data. In practice, this dual regime means: (a) businesses should employ robust encryption to safeguard personal data (as a technical measure under KVKK), and (b) any telecom or cybersecurity products involving encryption must comply with BTK\u2019s licensing or notification rules.<\/p>\n\n\n\n On 19 March 2025, T\u00fcrkiye enacted its first comprehensive Cybersecurity Law (No. 7545). This law establishes a central Cybersecurity Directorate and Council, empowers regular security audits, and imposes mandatory resilience measures for public institutions and critical sectors. Key provisions include: mandatory penetration testing and security audits for entities in designated critical infrastructure sectors, creation of special Cyber Incident Response Teams (SOMEs) at public agencies, and requirement for cyber-vendors to obtain Directorate approval before operating. Service providers must now report vulnerabilities or attacks promptly to the Directorate and submit requested technical information on demand.<\/p>\n\n\n\n The law also introduces severe penalties to enforce compliance. For example, operating without required cybersecurity authorization is punishable by 2\u20134 years imprisonment or fines of TRY 1\u201310\u202fmillion; causing damage to critical infrastructure by cyberattacks carries 8\u201312 years\u2019 jail. Illegally sharing or selling sensitive data incurs 3\u201315 years\u2019 imprisonment. Even companies failing to implement mandated cybersecurity measures or failing to report incidents can face administrative fines (from TRY 1\u201310\u202fmillion) or penalties up to 5% of annual turnover. Existing rules (e.g. in ICTA regulations) remain in effect until detailed regulations under the new law are issued.<\/p>\n\n\n\n For UK\/US companies, the new law means that any Turkish operations or critical services must evaluate applicability. Multinationals in finance, energy, health or tech should audit whether they fall under \u201ccritical sector\u201d definitions (for instance, telecom, banking and public utilities are included). If so, they must prepare for mandatory security audits, ensure executive accountability for cybersecurity, and comply with any certification\/authorization regimes introduced by the Directorate. Notably, cross-border controllers should note that Turkish cybersecurity law focuses on infrastructure and products \u2013 it does not directly override KVKK data rules, but both regimes share the goal of data confidentiality. A proactive compliance approach would integrate the new cybersecurity requirements (penetration testing, incident reporting, secure certification) with existing data protection programs.<\/p>\n\n\n\n In each scenario, the pattern is clear: non-compliance triggers regulatory action, whereas proactive alignment (e.g. timely VERBIS filing, using approved transfer contracts, having incident plans, registering encryption services) mitigates risk. International businesses expanding to T\u00fcrkiye should therefore integrate Turkish-specific requirements into their compliance checklists, combining KVKK obligations (registration, legal bases, breach rules) with new cybersecurity mandates (security audits, incident reporting) and telecom regulations on encryption. By doing so, they can operate in T\u00fcrkiye\u2019s market while minimizing liability under the evolving legal regime.<\/p>","protected":false},"excerpt":{"rendered":"Cross-Border Data Transfers<\/strong><\/h2>\n\n\n\n
