API Security Testing for BSS & Payment Platforms
REST, GraphQL & SOAP testing — specialized for the telecom BSS, payment gateway, and fintech APIs that carry your revenue.
Overview
APIs are the backbone of modern telecom and fintech platforms — and a prime target. We test against the full OWASP API Top 10 and apply custom logic exploitation designed for billing systems, payment gateways, and the complex business workflows that generic scanners cannot parse.

Questions
Frequently asked.
How do we share our API with you?+
Most clients provide a Postman collection or OpenAPI specification along with test credentials. We define scope together before testing.
Can you test telecom BSS and billing APIs?+
Yes — this is a core specialty. We test for billing bypass, revenue leakage, and transaction manipulation specific to telecom platforms.
Do you test GraphQL and SOAP, not just REST?+
Yes. We test REST, GraphQL, and SOAP APIs, each with techniques specific to that architecture.
