In 2025, cybersecurity is no longer a technical issue—it is a core legal risk. As cyberattacks grow in volume and sophistication, Turkish regulators have tightened laws around data protection, corporate responsibility, and breach notification. The legal framework includes KVKK (Turkey’s Data Protection Law), the Electronic Communications Law, the Criminal Code (Articles 243–246), and sectoral compliance directives. Our Turkish Law Firm helps businesses assess their cyber exposure, implement legal controls, and defend against both civil and criminal liabilities. If you're an international tech company or a domestic enterprise, working with an English speaking lawyer in Turkey is essential to build a legally robust cybersecurity posture.
Key Cybersecurity Laws in Turkey
Turkey’s cybersecurity legislation is spread across multiple statutes. The most central is KVKK, which governs personal data security. Breaches must be reported within 72 hours and may trigger administrative fines and civil claims. The Criminal Code criminalizes unauthorized access, system disruption, and data manipulation. Telecommunications providers are also regulated by the ICTA (Information and Communication Technologies Authority). Our Turkish Lawyers help companies align policies with these frameworks and coordinate with IT and legal departments. Istanbul Law Firm is considered a best lawyer firm in Turkey for businesses facing regulatory inspections and data breach litigation.
Corporate Responsibility and Director Liability
Board members and company executives can be held personally liable for failing to implement cybersecurity controls. Turkish Commercial Code Article 369 imposes a duty of diligence, which extends to information security. Our Company Lawyer Turkey team advises boards on adopting cyber risk governance, conducting internal audits, and documenting breach prevention strategies. English speaking lawyer in Turkey specialists on our team draft director resolutions, risk registers, and response protocols aligned with both Turkish and international standards. When negligence leads to financial loss or data compromise, plaintiffs can pursue civil damages under tort principles—and criminal liability may also apply.
Data Breach Notification and Regulatory Defense
When a data breach occurs, companies must notify KVKK and affected individuals promptly. Failure to notify can result in fines of up to 2% of annual revenue and criminal referrals. Our Turkish Law Firm assists clients in preparing breach notification templates, forensic reports, and legal statements for regulatory filings. As a best lawyer firm in Turkey for data protection, we provide legal triage services during cybersecurity crises. Our English speaking lawyer in Turkey team also works with PR advisors to ensure compliant external communications.

Cybercrime Investigations and Criminal Defense
Cybersecurity breaches in Turkey often trigger criminal investigations—especially in cases involving financial services, critical infrastructure, or public institutions. Articles 243–246 of the Turkish Penal Code impose prison sentences for hacking, data theft, and system sabotage. Istanbul Law Firm provides both corporate and individual defense in cybercrime cases. Our Turkish Lawyers handle inquiries by prosecutors, expert testimony coordination, and digital evidence challenges. If you're named in an investigation, having an English speaking lawyer in Turkey from a trusted Turkish Law Firm is essential to protect your rights and reputation.
Industry-Specific Cybersecurity Requirements
In Turkey, regulated sectors such as banking, telecom, healthcare, and e-commerce are subject to specific cybersecurity mandates. These include encryption standards, penetration testing, and business continuity planning. Our Company Lawyer Turkey team works across sectors to adapt internal policies to these frameworks. As a best lawyer firm in Turkey for cross-sector compliance, Istanbul Law Firm helps clients in finance, logistics, and retail maintain audit-readiness and legal defensibility.

Data Protection Compliance Under KVKK and GDPR
KVKK is Turkey’s cornerstone data protection law and heavily influences cybersecurity requirements. Companies must protect personal data from unauthorized access, loss, and tampering. With Turkey's EU accession goals, GDPR alignment is also a growing priority. Our Turkish Law Firm helps clients conduct Data Protection Impact Assessments (DPIAs), draft data processing agreements, and align AI-driven systems with KVKK Article 12. English speaking lawyer in Turkey professionals from our team coordinate cross-border compliance for EU-based clients. Istanbul Law Firm is a best lawyer firm in Turkey for tech companies needing both KVKK and GDPR alignment.

Employee Conduct and Internal Cybersecurity Policies
Employees are often the weakest link in cybersecurity. Turkish employers must provide clear IT usage policies, training programs, and incident escalation frameworks. Our Company Lawyer Turkey division designs internal compliance protocols that align with labor law, including termination clauses for data mishandling. Turkish Lawyers in our HR advisory team draft electronic monitoring disclosures under Article 419 of the Turkish Code of Obligations. An English speaking lawyer in Turkey ensures international employers respect both Turkish labor law and global HR standards in cybersecurity compliance.

Vendor Risk Management and Third-Party IT Contracts
In many cases, security failures come not from internal systems but from third-party service providers. Turkish law holds data controllers liable for breaches caused by vendors. Our Turkish Law Firm reviews all IT, cloud, and SaaS contracts to include cybersecurity clauses, SLAs, liability limitations, and audit rights. We ensure that data transfer contracts comply with KVKK and clarify incident notification duties. As a best lawyer firm in Turkey, we provide vendor onboarding checklists and dispute resolution strategies. If your vendor is international, our English speaking lawyer in Turkey team prepares cross-border DPA (Data Processing Agreements) compliant with local law.
Regulatory Enforcement: Fines, Investigations and Audits
KVKK and ICTA (Bilgi Teknolojileri ve İletişim Kurumu) regularly inspect data handlers for cyber compliance. Investigations can begin with whistleblower tips, public reports, or random audits. Fines can reach 5 million TRY or more for repeat offenders. Our Turkish Lawyers manage full audit response strategies—from data room prep to defense filings. If a client is fined, we handle objection petitions and litigation. Company Lawyer Turkey consultants prepare boards for media fallout, insurance notification, and stakeholder updates. An English speaking lawyer in Turkey helps translate findings into board-level action and international investor updates.
Cyber Insurance and Legal Structuring
Cyber insurance is an emerging requirement for many Turkish sectors. However, most policies require evidence of proactive legal compliance. Istanbul Law Firm helps clients design coverage-eligible security frameworks and handles insurer negotiations. Our Turkish Law Firm advises on legal document requirements, breach exclusions, and claim conditions. As a best lawyer firm in Turkey, we’ve structured cyber insurance systems for banks, energy providers, and logistics companies. Our English speaking lawyer in Turkey team also assists in filing claims and managing insurer communication post-breach.
International Obligations for Multinational Tech Operations
Companies with cross-border operations must meet compliance obligations in multiple jurisdictions. Turkey’s cybersecurity requirements increasingly mirror EU, GCC, and U.S. expectations. We provide multinational clients with harmonized policies, regional risk assessments, and jurisdictional legal mapping. Turkish Lawyers in our international desk collaborate with partner firms across Europe and MENA. A Company Lawyer Turkey can align your Turkish compliance with your global cyber playbook.

Cybersecurity Audits and Legal Risk Mapping
Regular cybersecurity audits are critical not only for IT readiness but also for legal defense. Turkish regulators expect companies to maintain evidence of internal controls, incident logs, and compliance documentation. Our Turkish Law Firm structures these audits with both legal and technical experts, producing reports suitable for court defense or regulatory submission. Istanbul Law Firm’s English speaking lawyer in Turkey team collaborates with IT security firms to translate risk findings into legal obligations. A Company Lawyer Turkey plays a vital role in ensuring these audits are integrated into corporate governance policies. For example, we helped a logistics firm avoid penalties by submitting a proactive audit after an employee-triggered ransomware attack.
Supplier and Vendor Security Liability
Companies are now being held responsible for data breaches caused by their service providers. Under Turkish data protection law, data controllers are liable for third-party errors unless safeguards are contractually defined. Our Turkish Lawyers review vendor agreements, insert liability-shifting clauses, and draft cybersecurity annexes. An English speaking lawyer in Turkey ensures these documents are enforceable under Turkish and foreign law. Istanbul Law Firm’s best lawyer firm in Turkey status is built on anticipating such risks and providing bulletproof documentation across IT, logistics, finance, and software vendor relationships.
Cybersecurity Obligations for E-Commerce and SaaS Providers
E-commerce and SaaS companies in Turkey are regulated by the Law on Electronic Commerce and must implement security protocols such as HTTPS, data encryption, and transaction integrity measures. Additionally, they must comply with consumer protection laws and digital sales taxation rules. Our Turkish Law Firm ensures SaaS platforms are compliant across multiple regulatory areas. A Company Lawyer Turkey also works with founders and product teams to integrate legal safeguards directly into the software lifecycle (DevSecOps). Learn how tech startups manage cross-functional compliance in our article: Startup Legal and Tax Strategy in Turkey.
International Data Transfers and Cross-Border Risk
Transferring personal data from Turkey to countries lacking adequate protection is restricted under KVKK. This includes cloud services, outsourcing, and international business collaboration. Our English speaking lawyer in Turkey team advises global clients on how to structure standard contractual clauses (SCCs), obtain Board approval, or localize storage. Our Turkish Lawyers also align cross-border transfers with GDPR, if the company is dual-regulated. These risks are especially critical in fintech and medtech sectors. We explain these complex intersections in: Cryptocurrency & Cross-border Inheritance Law.
Cyber Insurance: Legal Integration and Claims Handling
Cyber insurance is becoming a must-have in Turkish business, but claims are often denied due to poor legal structuring. Our Turkish Law Firm reviews policy terms, ensures alignment with corporate bylaws, and prepares board resolutions that support valid claims. Istanbul Law Firm’s litigation team has handled cyber policy enforcement across ransomware, data breach, and business interruption cases. A Company Lawyer Turkey also manages insurer communications during crisis response.

Enforcement Trends and High-Profile Cases in Turkey
