Manual API Security Testing for REST, GraphQL and gRPC in Australia

APIs are now the primary attack surface for Australian businesses. Modern Australian SaaS, fintech, Open Banking, healthcare, e-commerce and B2B platforms expose hundreds or thousands of REST, GraphQL and gRPC endpoints, and almost every recent Australian breach reported under the NDB scheme has involved an API failure, broken object level authorization, mass assignment, insecure direct object reference, missing rate limiting, exposed business logic or unauthenticated admin endpoints. Generic vulnerability scanners catch almost none of these.

Codesecure Solutions delivers manual API security testing to Australian businesses from our Chennai pentest practice. Every Australia API engagement is delivered by a named OSCP-certified consultant under a signed Australian-law NDA, with daily AEST or AEDT working day updates and a final report mapped to OWASP API Security Top 10, OWASP ASVS, SANS CWE Top 25, ACSC Essential Eight, APRA CPS 234, ISO 27001, and where relevant Consumer Data Right (CDR) and FAPI security profiles for Open Banking. Pricing is published in clear AUD bands.

API Security Testing Services in Australia We Deliver

Our Australia API security testing portfolio covers every kind of modern API stack:

  • REST API Penetration Testing: Manual testing across all OWASP API Top 10 and ASVS categories including BOLA, broken authentication, broken object property level auth, unrestricted resource consumption and unsafe consumption of APIs.
  • GraphQL API Penetration Testing: Manual GraphQL testing covering introspection, query complexity, batch attacks, depth and rate limiting, broken authorization at field level and information disclosure.
  • gRPC API Penetration Testing: Manual gRPC testing including reflection, authentication, authorization, deserialization and stream-based attack patterns.
  • Open Banking and CDR API Testing: Specialized testing for Australian Consumer Data Right APIs aligned to FAPI security profiles, OAuth flows, consent management and data minimization.
  • API Authentication and Authorization Audit: Deep audit of API auth: OAuth 2.0, OpenID Connect, JWT, mTLS, API keys, scopes, claims and authorization policy enforcement.
  • API Architecture and Threat Modeling: Architecture review and threat modeling for API gateways, service meshes, microservice topologies and BFF patterns.

Our Australia API Security Testing Methodology

Every API engagement follows a proven 5-phase methodology aligned to OWASP API Security Top 10 and ASVS Level 2.

Phase 1: Scoping and Documentation Review

Free scoping during AEST or AEDT, signed Australian-law NDA, fixed AUD price, review of OpenAPI, GraphQL schema or gRPC proto definitions.

Phase 2: Endpoint Discovery and Threat Modeling

Manual endpoint discovery, enumeration of authentication and authorization patterns, threat modeling against OWASP API Top 10 and your specific business logic.

Phase 3: Manual Exploitation

Hands-on testing by named consultants covering BOLA, broken authentication, mass assignment, broken object property auth, security misconfiguration and unsafe consumption with daily AEST or AEDT updates.

Phase 4: Reporting and Walkthrough

Auditor-ready report mapped to OWASP API Top 10, ASVS, Essential Eight, APRA CPS 234, ISO 27001 and CDR/FAPI plus a live walkthrough.

Phase 5: Retest and Sign-Off

Free retest of critical and high findings within 30 days, formal sign-off letter, customer data deleted 90 days after sign-off.

Frequently Asked Questions

A web application pentest tests the front-end UI, JavaScript, browser-side controls and the underlying APIs as one consolidated scope. An API-only pentest goes much deeper into the API itself, testing every endpoint independently of any UI, including endpoints not exposed by the UI, internal-only endpoints, server-to-server endpoints and abandoned versions still live in production. For API-heavy modern architectures including Open Banking, B2B integrations and microservices, an API-focused pentest finds issues that a web pentest never reaches.

Yes. Codesecure has tested Australian Consumer Data Right and Open Banking APIs for fintech, energy and Authorised Deposit-taking Institutions. Our methodology covers FAPI security profiles including FAPI 1.0 Advanced and FAPI 2.0, OAuth 2.0 flows including PAR and JAR, consent management and lifecycle, data holder and data recipient flows, error handling, rate limiting and CDR-specific obligations.

Codesecure publishes transparent AUD price bands. A small to mid-sized REST API pentest with up to 50 endpoints typically runs AUD 5,000 to 10,000 fixed price. Larger APIs with hundreds of endpoints or extensive business logic run AUD 10,000 to 25,000. GraphQL and gRPC APIs are priced similarly to REST. Open Banking and CDR API pentests attract a small premium due to FAPI complexity. Every quote includes free retest of critical and high findings.

Yes. Codesecure regularly tests APIs in pre-production and staging environments before they go live, including pen testing during release candidate phases. We can work with feature flags, partial implementations and continuously evolving endpoints. Some Australian customers also engage Codesecure on a quarterly retainer for ongoing API security testing as new endpoints ship through their CI/CD pipeline.

Yes. Every Codesecure API pentest report is mapped to the current OWASP API Security Top 10 (2023) including Broken Object Level Authorization (API1), Broken Authentication (API2), Broken Object Property Level Authorization (API3), Unrestricted Resource Consumption (API4), Broken Function Level Authorization (API5), Unrestricted Access to Sensitive Business Flows (API6), Server Side Request Forgery (API7), Security Misconfiguration (API8), Improper Inventory Management (API9) and Unsafe Consumption of APIs (API10), plus OWASP ASVS Level 2 controls.
