Spot GraphQL Introspection Leaks and Query-Abuse Patterns
GraphQL flattens the API surface into one endpoint, which means one mistake exposes the whole schema. The scanner probes introspection, query depth and complexity limits, field-level authorization, and aliasing / batching abuse.
Try GraphQL Scanner
How It Works
From target input to actionable findings in three straightforward steps.
Point at the Endpoint
Usually /graphql or /api/graphql. The scanner handles both GET and POST.
Introspect the Schema
Dumps every type, field, and directive the server will admit — and fails the check if introspection is open.
Abuse Patterns
Runs deep-nested queries, aliased batches, and field-level authorization probes to spot missing limits.
Key Capabilities
Purpose-built scanning backed by real penetration testing expertise.
Introspection Detection
Flags open introspection in production environments — the #1 GraphQL disclosure risk.
Query Depth Testing
Sends increasingly deep queries to find the depth at which the server stops responding or times out.
Alias / Batch Abuse
Tests whether aliased fields and query batching bypass rate limits or authorization.
Field-Level Auth
Attempts to access admin-only fields as an anonymous user to catch missing field guards.
Error-Message Disclosure
Inspects error responses for stack traces, internal hostnames, and schema hints.
No-Auth & Auth Modes
Works with open endpoints or authenticated targets when you paste a bearer token.
Common Use Cases
Why Use Pentestas
Security tools built by penetration testers, not just developers.
Enterprise-Grade Accuracy
Our scanning engine is built on the same methodologies our penetration testers use in manual engagements, tuned to minimize false positives and surface genuine risk.
Fast, Actionable Results
Get findings in minutes rather than days. Every result includes severity ratings, technical evidence, and clear remediation steps your team can act on immediately.
Continuous Monitoring
Schedule recurring scans from the Pentestas platform to catch regressions before they reach production. Stay ahead of new CVEs and configuration drift.
Privacy First
Your scan data is encrypted at rest and in transit. You own your data, with full control over retention and export.
Detailed Reporting
Export findings as PDF, CSV, or JSON. Feed results directly into your SIEM, ticketing system, or CI/CD pipeline through our REST API.
Instant Setup
Run scans directly from your browser. Enter a target, click scan, and receive results. Ready in under a minute.

API Penetration Testing: The Complete Guide to Securing REST, GraphQL, and gRPC Endpoints
APIs now account for over 80% of all web traffic, yet most organizations have never had their APIs professionally tested for security vulnerabilities. This guide covers the OWASP API Top 10, real-world attack scenarios, and exactly what to expect from a professional API penetration test.
