Service Overview

Protect the APIs that power your entire business

APIs are now the #1 attack vector — Gartner predicted APIs would surpass web apps as the most attacked surface, and that future has arrived. Broken object-level authorization (BOLA) alone accounts for the vast majority of serious cloud breaches in recent years.

CyberAlpha tests REST, GraphQL, SOAP, and gRPC APIs with deep manual analysis focused on OWASP API Security Top 10 risks: BOLA, broken authentication, excessive data exposure, lack of rate limiting, BFLA, mass assignment, security misconfiguration, injection, improper asset management, and insufficient logging.

We use your OpenAPI/Swagger, Postman, or GraphQL schemas to build comprehensive attack surface maps — then probe every endpoint, parameter, and auth flow for real-world abuse scenarios.

Schedule a Consultation

Direct Data Access

APIs expose databases, user records, and business logic without any UI layer to slow attackers.

BOLA Epidemic

Broken object-level authorization is the #1 API risk and the root cause of many recent mega-breaches.

Automation Abuse

Without rate limits, attackers scrape, brute-force, and enumerate APIs at massive scale.

JWT & OAuth Flaws

Signature confusion, weak secrets, and misissued tokens frequently bypass authentication entirely.

Why It Matters

APIs now drive most major breaches

Direct Data Access

APIs expose databases, user records, and business logic without any UI layer to slow attackers.

BOLA Epidemic

Broken object-level authorization is the #1 API risk and the root cause of many recent mega-breaches.

Automation Abuse

Without rate limits, attackers scrape, brute-force, and enumerate APIs at massive scale.

JWT & OAuth Flaws

Signature confusion, weak secrets, and misissued tokens frequently bypass authentication entirely.

Shadow & Zombie APIs

Forgotten staging, v1, and internal APIs remain live and unmonitored long after deprecation.

GraphQL Complexity

Introspection, query depth, and aliasing abuse create unique attack paths traditional tools miss.

What We Test

Full OWASP API Top 10 coverage

Every authorization flow, every parameter, every endpoint — REST, GraphQL, SOAP, and gRPC.

BOLA & BFLA

Object and function-level authorization testing across all user roles and tenants.

Authentication Flaws

JWT signature bypass, OAuth misconfig, API key leakage, and token replay attacks.

Excessive Data Exposure

Over-fetching, verbose responses, and PII leakage in nested JSON objects.

Rate Limiting & Resource

Brute force, scraping, and denial-of-wallet attacks on API endpoints.

Mass Assignment

Privilege escalation via unvalidated fields in JSON/form payloads.

Injection & SSRF

NoSQL, SQL, command, and server-side request forgery through API parameters.

Key Benefits

What our API testing delivers

01

Full Endpoint Coverage

Every endpoint in your OpenAPI, Postman, or GraphQL schema is tested systematically.

02

Authorization Matrix

We map every role to every endpoint and find the broken boundaries scanners miss.

03

Multi-Protocol

REST, GraphQL, SOAP, gRPC, and WebSocket APIs all covered by one engagement.

04

Shadow API Discovery

Find forgotten v1, staging, and internal APIs that should no longer be exposed.

05

Audit-Ready Reports

Accepted by SOC 2, PCI DSS, and HIPAA auditors with full evidence trail.

06

Free Retest

Post-remediation retest included to validate every fix.

Common Vulnerabilities

API flaws we find every engagement

BOLA

Changing an ID in a URL to access another user's data — the #1 API risk worldwide.

JWT None/Alg Confusion

Algorithm-switching attacks, weak secrets, and unverified signatures.

Mass Assignment

Adding "isAdmin":true to requests and gaining elevated privileges.

No Rate Limiting

Unlimited OTP, password reset, and login attempts enabling mass account takeover.

Excessive Data Exposure

APIs returning full user objects with hashes, tokens, and internal flags.

GraphQL Introspection

Production introspection enabled, query depth unbounded, and batching abuse.
