Most organizations in Turkey approach PDPL (Personal Data Protection Law, known as KVKK) compliance as a documentation exercise: disclosure notices, explicit consent forms, data inventories. Yet Article 12 of the Law defines a far broader obligation — the technical security of systems where personal data is processed also falls within the data controller’s responsibility.

So what happens when personal data transmitted through a web application, API integration, or corporate network is exposed in plaintext because an SSL/TLS certificate has expired or is misconfigured? This constitutes sufficient technical grounds for a KVKK violation.

What Does KVKK Article 12 Say?

Article 12 of the Personal Data Protection Law requires data controllers to “take all necessary technical and administrative measures to ensure an appropriate level of security in order to prevent unlawful processing of personal data, prevent unlawful access to personal data, and ensure the preservation of personal data.”

The phrase “all necessary technical measures” is broad. Protecting every communication channel, every application interface, and every API connection that carries personal data with a valid, properly configured SSL/TLS certificate is a natural component of this obligation.

Looking at data breach notifications in Turkey, it is evident that leaks occurring over unencrypted or certificate-error-prone channels represent a growing share of incidents. When this happens, the organization must both notify the Personal Data Protection Authority and demonstrate that it failed to implement adequate technical safeguards.

How Certificate Management Gaps Create KVKK Risk

1. Expired Certificates and Exposed Communication Channels

When a certificate expires, browsers and clients either refuse the connection or redirect users to an insecure channel. In this window, personal data transmitted through forms, login pages, or API calls faces the risk of plaintext exposure. Under KVKK, this can be classified as a failure to implement technical measures.

2. Invisible Certificates: The Inventory Gap

Do you know exactly how many active SSL/TLS certificates exist across your organization’s infrastructure? Most IT teams cannot answer this with confidence. A certificate on a server or service that is nearing expiry without anyone’s knowledge continues to create KVKK risk. “Not being aware” does not eliminate legal liability.

3. Third-Party Integrations

When processing personal data, organizations are held responsible not only for their own systems but also for the third-party systems they integrate with. If an API connection to a payment infrastructure, accounting software, or HR platform transmits personal data without verifying certificate validity, the liability rests with the data controller.

4. Data Sovereignty: Where Certificate Management Data Is Stored

This point is frequently overlooked. The metadata of your certificate management solution — which certificate is on which server, who the certificate owners are, which systems are covered — can itself qualify as sensitive organizational data. If a foreign-origin solution stores this data on servers outside Turkey, a separate assessment may be required under both KVKK and Law No. 5651.

Why Domestic Solutions Are Not Just a Technical Choice, But a Legal One

International certificate management platforms may offer technically mature solutions. However, Turkish organizations should not limit their evaluation to feature lists alone.

Support language and response time: During a certificate-related outage that also carries KVKK violation risk, relying on an English-language ticketing system can cost valuable hours. Real-time support in Turkish with a local team makes a concrete difference — both for resolving the technical issue and for managing the legal process correctly.

Data processing agreements and KVKK compliance: KVKK requires data controllers to enter into written agreements with data processors. Drafting a KVKK-compliant data processing agreement with a foreign software vendor often involves lengthy legal processes. A domestic provider can offer a much faster and more straightforward path.

Local retention: Keeping certificate management data on servers in Turkey or within the organization’s own infrastructure eliminates the risk of cross-border data transfer obligations under KVKK Article 9.

How SecTrail CM Changes the Picture

SecTrail Certificate Manager is a certificate lifecycle management platform developed by a Turkey-based engineering team with enterprise needs in mind. From a KVKK compliance perspective, several features stand out:

• Full inventory and visibility: SecTrail CM’s advanced network scanning technology automatically discovers all active SSL/TLS certificates across the organization’s network. It provides coverage comprehensive enough to invalidate any “I didn’t know” defense. The proactive technical measures required by KVKK Article 12 begin with this visibility.
• Automated renewal and zero-downtime target: Automating certificate renewal eliminates the risk of human error and oversight. Particularly given that certificate validity periods are set to drop to 47 days by 2029, automation is no longer optional — it is a necessity.
• Local support: Turkish-language interface, Turkish-language technical support, and the ability to execute a data processing agreement prepared within the Turkish legal framework. In a breach scenario that requires accountability before the Authority, the advantage of working with a local provider becomes tangible.
• On-premise deployment option: Keeping certificate metadata within the organization’s own infrastructure entirely eliminates the risk of cross-border data transfer.

What Should Your Organization Do?

For organizations that treat KVKK compliance and technical security as an integrated whole, three practical questions offer a useful starting point:

1. How many active SSL/TLS certificates exist on your organization’s network — and do you have full visibility into all of them?
2. Are there any upcoming certificate expirations on systems that process personal data?
3. Is your certificate management solution domestic? Has the data processing agreement been structured in compliance with KVKK?

If you cannot answer these questions clearly, conducting a certificate inventory may turn out to be an unexpected — but critical — step in your KVKK compliance journey.
