Application penetration testing

Application penetration testing for web apps, mobile apps, APIs, and the workflows people rely on.

We follow the user journey across browser, mobile client, API, identity, and workflow logic, then test the places where trust can break.

Application security testing interface
Review the app and backend as one system. Interface, API, identity flow, workflow logic, and the trust between them.

Web applications

Customer portals, SaaS products, internal tools, admin panels, booking flows, payment paths, and complex business logic.

Mobile apps

iOS and Android release paths, token handling, local storage, transport security, backend assumptions, and mobile-specific trust decisions.

APIs

Authentication, authorisation, object-level access control, tenant isolation, workflow logic, rate limiting, and error handling.

Included in the report

A clear summary for decision-makers plus reproducible technical findings and remediation guidance for engineers.

Review focus

Follow the user journey, then test where trust can break.

Testing begins only after the scope and permissions are agreed. We use established application-security practice, including OWASP guidance where it helps, but the review stays anchored to how your product actually works.

  • Authentication and session handling
  • Authorisation and role separation
  • Object-level access control and tenant boundaries
  • Input handling and injection exposure
  • Mobile-to-API trust assumptions
  • Plausible attack paths within the defined boundaries
  • Evidence and remediation guidance

Application review

Use application testing when risk crosses the browser, mobile app, API, identity, or workflow logic.

Teams usually ask for this before a launch, major release, inherited-code change, platform expansion, customer review, or procurement process.

Web, mobile, and API surfaces are grouped because the risk spans more than one layer.

The report gives engineers issues they can reproduce, security teams the context to triage, and customer-facing teams a plain-language summary.

What you get

Findings for engineers, customers, and procurement.

A focused application review gives engineers reproducible issues, security teams a way to prioritise, and decision-makers enough context to act.
