Cawght
Browser Extension — Chrome & Firefox

Does your app enforce
its own rules?

Cawght understands how your app works, generates adversarial test scenarios, executes them, and tells you where the business logic breaks.

How it works

Traditional scanners can't catch this

Tools like Snyk and Burp Suite catch XSS and SQL injection — but they don't know that your discount code should only work once, or that only admins can delete posts. Business logic flaws require understanding what the feature is supposed to do.

How it works

01

Install the browser extension

Add Cawght to Chrome or Firefox. Sign in with Google and you're ready to go.

02

Use your app normally

Open the side panel, click Start, and use the feature you want to test. Cawght observes how your application behaves.

03

AI generates attack scenarios

Cawght analyzes your application and generates adversarial test scenarios — can a coupon be reused? Can a regular user access admin features? Can boundaries be bypassed?

04

Review, execute, get findings

Review the scenarios, approve or skip, then execute. Cawght runs the tests, evaluates the results, and shows you exactly where business rules break — with evidence.

What Cawght tests

Can a regular user do admin-only actions?

IDOR

Can one user access another's data by changing an ID?

Race Condition

Can limits be bypassed via concurrent requests?

Boundary Violation

Can numerical boundaries be violated?

Parameter Tampering

Can request params like price or role be changed?

State Manipulation

Can workflow steps be skipped?
