Your web app, testedlike an attacker would.
Agents map your routes, roles, and auth flows, then attack them. Injection, broken access control, auth bypass, and logic flaws, each proven with a working exploit.

[ how it works ]
How web applicationpenetration testing works.
01
Map the app
Agents crawl the running application, load your OpenAPI spec, or read the source, and catalogue every route, parameter, role, and auth flow.
02
Attack it
Whitebox, greybox, or blackbox. Agents probe injection points, session handling, access control, and business logic in parallel.
03
Prove and report
Each finding is reproduced with a working exploit, tagged with its CWE, and delivered with reproduction steps and a fix.
[ coverage ]
The vulnerabilities thatget exploited.
The OWASP classes and the logic flaws that never appear on a checklist, for SPAs, server-rendered apps, and hybrids.
Injection
SQL, command, and template injection, and server-side request forgery.
Broken access control
IDOR, privilege escalation, and tenant boundary violations across every role.
Authentication and sessions
Login flows, OAuth and SSO, session fixation, token handling, password reset logic.
Cross-site scripting
Stored and reflected XSS, with a working payload for each.
Business logic
Checkout, invoicing, approvals, and other flows an attacker can abuse one legitimate request at a time.
The APIs behind it
REST, GraphQL, and gRPC endpoints your front end calls, authenticated or not.

[ definition ]
What is web application penetration testing?
Web application penetration testing is a controlled attack on a web app. It looks for what a real attacker could exploit: injection, broken access control, weak authentication, cross-site scripting, and logic flaws. Parameter's agents map the app's routes, roles, and auth flows, then attack them in parallel. Each finding is reproduced with a working exploit before it is reported.
