OWASP API Top 10 Coverage

API Penetration Testing.
Find What Scanners Miss.

Broken authentication, excessive data exposure, mass assignment, and business logic flaws don’t show up in automated scans. Our OSCP-certified testers manually probe every endpoint — REST, GraphQL, and beyond. Starting at $2,000.

Methodology

Proven Methodology. Zero Guesswork.

Every API engagement follows OWASP API Security Top 10 and PTES standards — the same framework top-tier consultancies use, without the enterprise price tag.

01

Endpoint Discovery

Full API surface mapping — documented and undocumented endpoints, versioned routes, hidden admin endpoints, and authentication flows your team may have forgotten.

02

Vulnerability Enumeration

We probe for OWASP API Top 10 flaws — broken auth, excessive data exposure, rate limit bypass, and injection — then manually validate every finding.

03

Manual Exploitation

OSCP-certified testers exploit real weaknesses to prove business impact — chaining auth bypass with data exposure to demonstrate actual breach scenarios.

04

Reporting & Remediation

Prioritized findings, reproduction steps, fix guidance per endpoint, and a free retest once you’ve patched. Delivered in 5 business days.

What We Test

REST, GraphQL & Beyond

Your API is the backbone of your product. We test every layer — authentication, authorization, business logic, and data handling.

Authentication & Authorization

Who Can Access What

Broken auth is the #1 API vulnerability. We test token handling, session management, OAuth flows, API key exposure, and every authorization boundary in your system.

  • Broken object-level authorization (BOLA/IDOR)
  • JWT & OAuth token attacks
  • Broken function-level authorization
  • API key leakage & rotation testing
  • Privilege escalation via endpoint manipulation
Best for: SOC 2 · HIPAA · SaaS Products
Business Logic & Data

What Scanners Can’t Find

Mass assignment, excessive data exposure, rate limit abuse, and logic flaws require a human tester who understands how your application is supposed to work — and finds where it doesn’t.

  • Mass assignment & parameter tampering
  • Excessive data exposure in responses
  • Rate limiting & resource exhaustion
  • Injection attacks (SQL, NoSQL, command)
  • GraphQL introspection & query abuse
Best for: PCI DSS · ISO 27001 · Pre-Launch Testing
Why Us

Why Security Leaders Choose Affordable Pentesting

Enterprise-grade API pentesting without the six-figure invoice. Here’s what you get on every engagement.

$

Transparent Flat-Rate Pricing

Starting at $2,000. No surprise scope changes, no hourly gotchas. You get a fixed quote within 24 hours of scoping.

5-Day Report Turnaround

Most engagements kick off within 48 hours and deliver an audit-ready report in five business days — not five weeks.

OWASP API Top 10 Mapped

Every finding is mapped to OWASP API Security Top 10 and relevant compliance controls — SOC 2, HIPAA, PCI DSS, ISO 27001, and NIST.

Actionable, Not Academic

Every finding includes endpoint-level reproduction steps and remediation guidance your developers can ship against in the next sprint.

Free Retest Included

After you patch, we retest every affected endpoint and deliver an updated clean report for your auditor — at no additional cost.

Human Testers, Not Bots

OSCP-certified pentesters who understand application logic. Automated scanners can’t find business logic flaws. Humans can.

What Clients Say

Trusted by Teams That Can’t Afford Mistakes

From SaaS startups prepping for SOC 2 to security-conscious engineering teams — our API pentests uncover what automated tools miss every time.

★★★★★

“They found a BOLA vulnerability in our API that let any authenticated user access any other user’s data. Our own security tool had been running for six months and never flagged it. The report was clear enough for our devs to fix it in two days.”

Series B SaaS Platform
★★★★★

“We needed an API pentest for our SOC 2 audit and had two weeks. They scoped it same day, kicked off within 48 hours, and delivered a clean auditor-ready report with five days to spare. Retest confirmed everything was patched.”

FAQ

Common Questions About API Pentesting

What APIs do you test?

We test REST, GraphQL, SOAP, and gRPC APIs. If you have API documentation (Swagger, Postman, OpenAPI), we use it as a starting point — but we also discover undocumented endpoints manually.

How is this different from a DAST scan?

DAST tools find low-hanging fruit. An API pentest finds broken authorization, mass assignment, and business logic flaws that only a human tester who understands your application can identify. Our testers manually chain vulnerabilities into real attack scenarios.

Will testing affect my production API?

No. We use safe techniques designed to prove risk without disrupting service. You’ll have a dedicated Slack or email channel with your tester throughout, and we can test against a staging environment if preferred.

Does an API pentest satisfy SOC 2 and PCI DSS requirements?

Yes. Our reports map findings to SOC 2 Trust Services Criteria, PCI DSS requirements, HIPAA technical safeguards, and ISO 27001 controls. One test, every auditor covered.

Do I need to provide API credentials or documentation?

We offer both authenticated (with credentials) and unauthenticated testing. Providing test credentials and API docs helps us go deeper — but we can also start from scratch to simulate a real attacker with no prior access.
