API Security Scanner — Test Your APIs for Real Vulnerabilities | Nurbak
API SECURITY SCANNER

Find the vulnerabilities in your APIs

APIs are where the data and the money live — and where most breaches happen. Nurbak's API security scanner finds broken authentication, CORS misconfigurations, exposed backends and injection points. Scan a public repo free.

Finds broken authentication

Missing auth checks, weak token handling and BOLA/IDOR — the OWASP API Top 10 issues that leak other users' data.

Catches CORS misconfigurations

A reflected origin with credentials lets any site read your API. We flag the exact policy that exposes you.

Maps the backends you expose

It reads your code to find the hosts and endpoints your app talks to, then checks each for weak configuration.

Private by design

Runs on our own model on ephemeral infra; your code and API details never reach a third-party AI and aren't stored.

How the API security scan works

1

Paste a public repo, or connect a private one read-only.

2

We map the API routes and backends from the code.

3

The model checks auth, CORS, input handling and exposure.

4

You get prioritized findings with impact and fix.

5

Add uptime and drift monitoring on a plan.

API security scanner FAQ

What API vulnerabilities does it find?

Broken object-level and function-level authorization (BOLA/BFLA), broken authentication, CORS misconfiguration, injection, mass assignment and exposed backends — aligned with the OWASP API Security Top 10.

Does it test my running API or my code?

It analyzes your repository to find the API surface and its weaknesses. Combined with Nurbak's monitoring, it also checks exposed backends passively.

Is it free?

Scanning a public repository is free with no account. Private repos, monitoring and the full report are on paid plans.

Is my API sent to a third party?

No. Analysis runs on our own model on ephemeral infrastructure; your code and API details are deleted after the scan and never reach OpenAI or Anthropic.
