Authentication
Tokens, keys, expiry, renewal, revocation and resistance to abuse.
API penetration testing
Find authorization flaws and data exposure between endpoints and integrations.
Penetration testing for REST and GraphQL APIs, focused on authentication, authorization, data and object exposure, and business rules.
REST and GraphQL OWASP API Security Tokens and business rules
When this matters
APIs expose data and decisions the interface can hide.
The assessment looks at how endpoints, objects, identities and integrations behave when they receive calls outside the expected flow.
01
Public or partner APIs
02
Mobile apps and decoupled frontends
03
Service-to-service integrations
04
Migration or launch of a new version
Coverage
Essential controls assessed in APIs.
We use documentation, collections and credentials when available to go deeper.
Object-level authorization
Improper access to records, resources or actions that belong to other users.
Data exposure
Excessive fields, sensitive information and responses that reveal internal detail.
Flow abuse
Limits, automation, operation sequences and exploitable business rules.
Inside the delivery
See how this work takes shape.
From technical alignment to delivery, the work has to leave context, evidence and next steps visible to everyone involved.
01 / 04
Process
An assessment guided by the API's real surface.
Documentation speeds the work up, but endpoints are also correlated from the application and the infrastructure.
Scope and rules of engagement
We document assets, access, limits, execution window and owners before any activity starts.
Guided assessment
Vorvex specialists carry out the work, with Apex supporting reconnaissance, correlation and evidence handling.
Validation and prioritization
Findings are analyzed for exploitability, technical impact and consequence for the business.
Report and retest
We deliver reproducible evidence and recommendations and, when contracted, validate the fixes you applied.
Deliverables
Enough context to fix without guesswork.
The evidence states the endpoint, identity, request, response and observed impact.
Executive view of risk
Exposure summary, priority impacts and next steps to support decisions and investment.
Evidence to fix with
Technical detail, context, reproduction steps and practical remediation guidance.
Traceable record
Scope, period, methodology and finding status documented for audit and accountability.
Frequently asked questions

If your question isn't here, talk to the team directly.
Ask on WhatsAppDo you test REST and GraphQL?+
Yes. Coverage is defined according to the technology, authentication, documentation and business flows available.
Is a Swagger file or Postman collection required?+
No, but documentation or collections increase coverage and cut the time spent discovering endpoints.
Does the test include mobile apps?+
The backend and the APIs the app uses can be included. Analysis of the mobile binary has to be described separately in the scope.
Next step
Need to validate an API before releasing an integration?
Share the type of API, the documentation you have and how many access roles exist.
