How key sectors in Türkiye use security testing services
Security Testing Services for E-commerce
E-commerce businesses in Türkiye usually need fast storefronts, omnichannel inventory, loyalty and frictionless checkout. For them, our security testing services typically starts with web application testing (injection, cross-site scripting, broken authentication and session handling checks) and adds mobile app security as the platform grows. Progress is tracked on checkout conversion and stock accuracy.

For them, our security testing services typically starts with api security testing (authorisation, object-level access, rate limiting and data-exposure testing on endpoints) and adds vulnerability assessment as the platform grows. Progress is tracked on deposit-to-trade conversion and withdrawal processing time.
Security Testing Services for Gaming
Gaming businesses in Türkiye usually need scalable game backends, player wallets, live-ops tooling and anti-fraud controls. For them, our security testing services typically starts with mobile app security (insecure storage, weak transport security, login and access-control checks on Android and iOS builds) and adds access-control review as the platform grows. Progress is tracked on daily active players and retention day 7.
Security Testing Services for Manufacturing
Manufacturing businesses in Türkiye usually need production planning, quality traceability, machine data and supplier collaboration. For them, our security testing services typically starts with vulnerability assessment (automated scanning plus manual verification, with false positives removed) and adds remediation support as the platform grows.

Progress is tracked on overall equipment effectiveness and scrap rate.

Payments would run through TROY, data would be handled under KVKK, and success would be measured on deposit-to-trade conversion, withdrawal processing time and share of assets in cold custody.
Example: security testing services for a gaming business in Diyarbakır
Consider a gaming company in Diyarbakır (regional commerce and services). A typical security testing services engagement would start with vulnerability assessment, then access-control review, and finish the first release with remediation support — usually within 2–3 weeks.

Regulators that can shape security testing services in Türkiye
Depending on your product, these authorities may set requirements that affect security testing services:
BDDK
Türkiye's Banking Regulation and Supervision Agency, which licenses banks and supervises IT and data-localisation rules. For security testing services, payment licensing, safeguarding of client funds and operational resilience are the usual focus.
CMB (crypto asset service providers)
The Capital Markets Board of Türkiye, which licenses crypto-asset service providers under 2024 legislation. For security testing services, the key questions are whether any token, investment or trading feature is regulated and how investors are protected.
CBRT
The Central Bank of the Republic of Türkiye, which licenses payment and e-money institutions and runs the FAST instant-payment system. For security testing services, payment licensing, safeguarding of client funds and operational resilience are the usual focus.

KVKK: compliance checklist for security testing services
Before launch in Türkiye, we work through this checklist with your team and advisers:
- Map every personal-data field to a lawful purpose under KVKK.
- Decide where data is hosted and whether data about Türkiye customers must stay in-region.
- Implement consent records plus data-subject access and deletion workflows.
- Encrypt data in transit and at rest; restrict and log administrative access.
- Prepare a breach-notification procedure that meets the timelines that apply in Türkiye.
- Review contracts and data-processing agreements for every third-party service.
Hosting and data residency for security testing services in Türkiye
For clients in Türkiye we usually host on Local Turkish data centres or nearby EU regions, subject to data-transfer rules. The choice balances latency for local users, KVKK requirements on where personal data may be stored or transferred, and any sector rules your regulator sets. Backups and disaster-recovery copies follow the same residency decision.
