How key sectors in Bulgaria use security testing services
Security Testing Services for IT outsourcing
IT outsourcing businesses in Bulgaria usually need fast release cycles, scalable multi-tenant architecture and extra senior engineering capacity. 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 release frequency and customer churn.
Security Testing Services for Fintech
Fintech businesses in Bulgaria 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 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 onboarding completion rate and time to approve an application.
Security Testing Services for E-commerce
E-commerce businesses in Bulgaria usually need fast storefronts, omnichannel inventory, loyalty and frictionless checkout. 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 checkout conversion and stock accuracy.
Example: security testing services for a it outsourcing business in Varna
Consider a it outsourcing company in Varna (port, tourism and tech firms). 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.
Payments would run through Cards, data would be handled under EU GDPR, and success would be measured on release frequency, customer churn and time to onboard a customer.
Example: security testing services for a fintech business in Plovdiv
Consider a fintech company in Plovdiv (manufacturing and it outsourcing). A typical security testing services engagement would start with web application testing, then api security testing, and finish the first release with mobile app security — usually within 2–3 weeks.
Payments would run through SEPA, 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.

- Decide where data is hosted and whether data about Bulgaria 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 Bulgaria.
- Review contracts and data-processing agreements for every third-party service.
Hosting and data residency for security testing services in Bulgaria
For clients in Bulgaria 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.
