Probe the Backend APIs That Actually Power Your Mobile App
The riskiest attack surface isn't the mobile binary — it's the backend it talks to. The scanner extracts endpoints from the mobile app (or a HAR capture) and runs API-focused checks: auth, BOLA, mass-assignment, JWT, rate-limit, and data exposure.

How It Works
From target input to actionable findings in three straightforward steps.
Supply the Endpoints
Upload a HAR file captured from the app, or paste the base URL if the API surface is already known.
Authenticate the Scanner
Paste a bearer token or a refresh-token flow so the scanner can reach authenticated endpoints.
API-focused Scan
Every endpoint is tested for auth / authorization / injection / business-logic weaknesses.
Key Capabilities
Purpose-built scanning backed by real penetration testing expertise.
HAR Import
Capture the mobile app with a MITM proxy and upload — we derive the complete endpoint list automatically.
Auth Variants
Bearer, custom header, refresh-token flow supported out of the box.
BOLA + BFLA
Attempts to access other users / tenants resources to surface broken object- and function-level authorization.
Mass-Assignment
Sends extra fields (role, admin, tenant_id) on write requests to spot missing field filters.
JWT Weakness
If the app uses JWT, the scanner inspects signing, expiry, and claim handling.
Rate-Limit Probe
Fires bursts to see whether login / password-reset / search endpoints throttle correctly.
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.
