Who this test is for

Built for development teams and technology leaders running a business application who want a real picture of their security before a customer review, a release or a significant change.

Multi-tenant SaaS products

Systems where multiple customers share infrastructure, and isolation between them is a critical requirement.

Customer portals and personal areas

Systems that show personal data, documents or financial information to signed-in users.

Internal business applications

Management systems with many roles, where a wrong permission grants too much power.

What actually gets tested

Coverage is tailored to the agreed scope. These are the core areas examined in an application test.

Access control between users and roles, including access to another account's data
Authentication flows, password reset and session management
Input validation and injection attempts in the application's context
Business logic: pricing, action permissions, invalid process states
File uploads and handling of user-supplied files
Configuration, security headers and unnecessary information exposure

Coverage is set by the scope agreed in advance. No dangerous exploitation and no scanning of systems not approved in writing.

Application testing FAQ

Can the test affect system availability?

A coordinated application test significantly reduces the risk, including through an approved environment, a defined time window and a stop contact. However, zero impact can't be guaranteed, which is why coordination is defined in advance.

How is this different from an API test?

An application test focuses on the user interface and product flows, including the layer behind them. An API test focuses on the endpoints themselves, object- and function-level authorization and data exposure. Both can be combined in one scope.

Do you also test infrastructure or networks?

No. This service focuses on Web applications, SaaS platforms and APIs. Infrastructure, network or mobile testing is not part of this offering.
