Security Testing Services in Croatia: market overview
Companies in Croatia increasingly look offshore for security testing services. Croatia's strong tourism sector and growing tech scene — including gaming and mobility startups — create demand for booking, payment and product engineering.
Demand is strongest across Tourism, Gaming and Fintech, and every engagement is shaped by local regulation, payment habits and working hours rather than a one-size-fits-all template.

How key sectors in Croatia use security testing services
Security Testing Services for Tourism
Tourism businesses in Croatia usually need direct booking engines, guest apps and channel-manager integrations. 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 direct booking share and occupancy.
Security Testing Services for Gaming
Gaming businesses in Croatia 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 Fintech
Fintech businesses in Croatia usually need secure onboarding, ledgers that reconcile to the cent, real-time payments and audit-ready reporting. 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 onboarding completion rate and time to approve an application.
Example: security testing services for a fintech business in Dubrovnik
Consider a fintech company in Dubrovnik (luxury tourism and travel services). A typical security testing services engagement would start with api security testing, then mobile app security, and finish the first release with vulnerability assessment — usually within 2–3 weeks.
Payments would run through SEPA Instant, data would be handled under EU GDPR, and success would be measured on onboarding completion rate, time to approve an application and fraud loss rate.
Example: security testing services for a gaming business in Zagreb
Consider a gaming company in Zagreb (tech startups, banks and government). A typical security testing services engagement would start with access-control review, then remediation support, and finish the first release with web application testing — usually within 2–3 weeks.
Payments would run through Cards, data would be handled under EU GDPR, and success would be measured on daily active players, retention day 7 and payment success rate.

EU GDPR: compliance checklist for security testing services
Before launch in Croatia, we work through this checklist with your team and advisers:
- Map every personal-data field to a lawful purpose under EU GDPR.
- Decide where data is hosted and whether data about Croatia 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 Croatia.
- Review contracts and data-processing agreements for every third-party service.
Hosting and data residency for security testing services in Croatia
For clients in Croatia we usually host on Frankfurt, Ireland or another EU region to stay within GDPR transfer rules. The choice balances latency for local users, EU GDPR 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.
