Frequently Asked Questions about API Security Testing Services

Explore everything you need about GigaTester’s API security testing services, including process, benefits, timelines, and why it’s critical for your business safety.

Why is API security testing important?

APIs are prime targets for hackers. Testing ensures vulnerabilities are found and fixed early, protecting your users, data, and reputation.

We test REST, SOAP, GraphQL, WebSocket APIs, and more—across all industries and environments.

Ideally, after every major update, annually at minimum, and whenever there are significant system changes or threats evolve.

It varies depending on complexity, but most API security tests are completed within 1 to 2 weeks.

You’ll get a detailed vulnerability report, risk ratings, recommended fixes, and a consultation with our security experts.
