Common attack paths and issues tested

Broken object-level authorization

We test where user-controlled identifiers let standard accounts access or modify records that should belong to another customer or internal role.

Workflow abuse and state manipulation

We validate how multi-step flows can be replayed, skipped, or reordered to bypass approval logic or charge controls.

Upload and processing chains

File handling paths are tested beyond the first upload request to include storage, preview, transformation, and downstream workers.

Frequently asked questions

Do you test only the public UI?

No. We test the application as a system, including hidden routes, user roles, client-server trust assumptions, APIs, and downstream processing where relevant.

Can this be done against staging?

Yes. Many teams prefer staging for broader test freedom, but we can also scope targeted production validation with guardrails where required.
