API Pentesting By Industry

# API penetration testing built around your industry

The APIs that matter are not the same for a SaaS platform, a fintech, a healthcare provider, or an AI company. Each carries its own critical API risk and its own compliance driver: multi-tenant isolation, money movement, patient data, or agent and model access. Choose your industry to see how agentic, continuous API testing applies to the surface you actually run.

How We Scope

## Why the industry changes what we test first

Every API surface hides the same handful of flaw classes: broken object level authorization, broken function level authorization, broken authentication, and injection. What changes by industry is which operation carries the most damage if one of those shows up, and which regulator or auditor is going to ask you to prove it does not. A SaaS platform's highest-risk operation is usually the one that reads or writes another tenant's data. A fintech's is the one that moves money. A healthcare API's is the one that returns a patient record. An AI company's is the one a model or agent can call on a user's behalf.

That is why Operator does not run one fixed checklist against every target. It reads your OpenAPI spec, maps each operation to the roles and tenants that can call it, and prioritizes the authorization and injection paths that match your industry's actual blast radius first, then still tests every operation in the spec. Every finding it reports carries a runnable proof-of-concept your engineers can replay, not a severity score you have to take on faith.

FAQ

## Common questions

Do all industries need the same API penetration testing?

No. The most common vulnerability classes, broken object and function level authorization, broken authentication, and injection, show up everywhere, but the operation that carries the most risk if one is found differs by industry. Operator scopes each run to the operations and roles that matter most for your industry, then tests every operation in your spec regardless.

Which page should I read for my industry?

Use the table above to jump to your industry's page: SaaS, fintech, healthcare, or AI companies. Each page details the top API risk, the compliance driver behind it, and how Operator tests for it, with an example finding.

What if my company spans more than one industry, like a fintech built on AI agents?

Most real targets do not fit one label. Tell us your API surface and the compliance frameworks you carry, and we scope a run that combines the relevant checks, such as money-movement logic and agentic tool authorization together, rather than picking a single industry template.
