What We Deliver

Security Testing Focused on API Risk

From authentication flows to OWASP API Top 10 checks we help you find and fix the vulnerabilities that matter.

Auth & Authorization Testing

Validate login, tokens, roles, and permission boundaries across endpoints.

  • JWT
  • OAuth
  • RBAC

OWASP API Top 10 Coverage

Structured checks against common API security risks and misuse patterns.

  • Top 10
  • Risk Mapping
  • Evidence

Injection & Input Abuse

Probe for injection, malformed payloads, and unsafe input handling.

  • SQLi
  • Payload Fuzzing
  • Validation

Token & Session Security

Assess token lifetime, storage assumptions, and session misuse risks.

  • Expiry
  • Replay
  • Secrets

Rate Limiting & Abuse Controls

Verify throttling, brute-force protections, and abuse resistance.

  • Throttling
  • Brute Force
  • Abuse Cases

Vulnerability Reporting

Clear findings with severity, reproduction steps, and remediation guidance.

  • Severity
  • Repro
  • Remediation
Our Process

From Threat Context to Hardened Endpoints

A clear API security workflow that moves from asset mapping to actionable remediation.

1

Discover

Map APIs, auth model, and sensitive data flows.

2

Plan

Define threat focus and test scope.

3

Test

Execute auth, access, injection, and abuse checks.

4

Report

Document vulnerabilities with severity and evidence.

5

Retest

Verify fixes and update residual risk notes.

Tools & Methods

Practical Tooling for API Security Assurance

We combine API clients, scanners, and manual expertise for credible findings.

Test Coverage

Coverage Across the Risks APIs Face Most

We prioritize the controls that protect identity, data, and business operations.

Authentication

Validate identity flows and credential handling.

Broken Object Access

Check unauthorized access to other users’ resources.

Injection

Probe unsafe input handling and query abuse.

Misconfiguration

Find insecure defaults, verbose errors, and exposure risks.

Rate Limits

Verify abuse controls under repeated and automated requests.

Reporting

Actionable findings with severity and fix guidance.

FAQ

Frequently Asked Questions

Have questions about API security scope, OWASP coverage, timelines, or retesting? Here are answers to common questions about API security projects with echoBitz.

Start an API Security Project

We typically cover authentication, authorization, injection, misconfiguration, token security, rate limiting, and vulnerability reporting aligned to your API surface.

Yes. We use OWASP API Top 10 as a core risk framework and tailor checks to your endpoints and auth model.

A focused API set may take one to a few weeks depending on endpoint count, auth complexity, and environments. We scope after discovery.

Yes. Each finding includes severity, evidence, reproduction steps, and practical remediation guidance.

Yes. Retesting is part of a complete engagement so you can confirm fixes before release.
