Security Testing Services in Luxembourg: market overview
Companies in Luxembourg increasingly look offshore for security testing services. Europe's fund-administration capital and an EMI licensing hub, Luxembourg needs fund-tech, tokenisation and payment platforms.
Demand is strongest across Fund administration, Payments (EMI) and Crypto (MiCA), 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 Luxembourg use security testing services
Security Testing Services for Fund administration
Fund administration businesses in Luxembourg usually need reliable, integrated software that removes manual work and scales with growth. For them, our security testing services typically starts with access-control review (role boundaries tested so users cannot see or change other users’ data) and adds web application testing as the platform grows. Progress is tracked on manual hours saved and error rate.
Security Testing Services for Payments (EMI)
Payments (EMI) businesses in Luxembourg usually need high approval rates, local payment methods, payouts and automated reconciliation. For them, our security testing services typically starts with remediation support (risk-ranked findings, fix guidance for developers and retesting to confirm closure) and adds api security testing as the platform grows. Progress is tracked on authorisation rate and cost per transaction.
Security Testing Services for Crypto (MiCA)
Crypto (MiCA) businesses in Luxembourg usually need licence-ready custody, transaction monitoring, wallet security and clear user disclosures. 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 deposit-to-trade conversion and withdrawal processing time.

EU GDPR: compliance checklist for security testing services
Before launch in Luxembourg, 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 Luxembourg 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 Luxembourg.
- Review contracts and data-processing agreements for every third-party service.
Hosting and data residency for security testing services in Luxembourg
For clients in Luxembourg 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.
