Deep security assessment of REST, GraphQL, gRPC, and WebSocket APIs. We test every endpoint, parameter, and workflow for authorization flaws, data exposure, and logic vulnerabilities.
Complete coverage of the OWASP API Security Top 10 — the standard for API vulnerability assessment.
IDOR vulnerabilities where attackers manipulate object IDs in API requests to access other users' data without proper authorization checks.
Weak API authentication mechanisms, missing token validation, insecure API key management, and credential exposure in API traffic.
Mass assignment & excessive data exposure — APIs returning more data than needed or accepting property updates they shouldn't.
Missing rate limiting, pagination abuse, large payload attacks, resource-intensive operations without throttling controls.
Accessing admin endpoints as regular user, HTTP method tampering (GET vs DELETE), and missing role-based endpoint restrictions.
Automated abuse of business-critical flows: bulk purchasing, credential stuffing, spam registration, scraping without bot protection.
SSRF via URL parameters, webhook URLs, file imports, and any API parameter that triggers server-side HTTP requests.
Missing CORS headers, verbose errors exposing stack traces, unnecessary HTTP methods, default configurations, and TLS issues.
Shadow APIs, deprecated endpoints still accessible, undocumented API versions, and forgotten debug/staging endpoints in production.
Trusting third-party API responses without validation, following redirects blindly, and processing unvalidated data from external services.
Real vulnerabilities we consistently find across REST, GraphQL, and WebSocket APIs.
JSON/XML endpoints, CRUD operations, pagination, filtering
Queries, mutations, subscriptions, schema analysis
Protocol buffers, streaming, service reflection, auth
Real-time messaging, event-driven APIs, pub/sub
APIs are the backbone of modern applications — and the #1 attack vector. Let us find the gaps.
