Types of application security testing

Applications change with every release, and each type of test answers a different question. Which combination fits depends on your release cycle, your assurance requirements and the teams who will act on the findings. We'll work through the options with you.

Web application testing

You get hands-on testing from our consultants alongside automated scanning, measured against the OWASP Top 10 and beyond. Coverage runs across authentication and session management, access control between user roles, injection, the APIs your application calls, and the business logic flaws that surface only when a real user path is followed. Each finding reaches you with technical evidence, a risk rating and the change that resolves it.

Mobile application testing

Your iOS and Android applications are tested across three layers: the package itself, how it behaves on the device, and the services it communicates with. Coverage includes local data storage, credential handling, certificate pinning, and the API traffic between the app and your backend, where authorization gaps and excessive data exposure often sit.

Application threat modelling

Your architects sit down with our consultants to map how the application could be attacked, working from its design, data flows and trust boundaries. Design-level risk surfaces while changes are still inexpensive to make.

 

Your security and development teams hear the findings together, with the reasoning behind each priority attached.

 

Benefits of Application Security Testing

  • Findings your developers will act on: Practical details that allow your development team to resolve each issue and avoid reintroducing it later.

  • Risk you can size: Expert validation, contextual risk ratings and evidence of how each weakness could be exploited in your environment.

  • Fewer false positives: Automated tooling combined with manual analysis, leaving your team with findings worth their time.

  • Evidence for audit and compliance: Independent assessment, documented for the standards and frameworks you report against.

  • Remediation confirmed: Targeted retesting verifies that each fix has resolved the issue.

  • Coverage you can account for: A running record of which applications have been tested, when, and what is still outstanding across your portfolio.

CREST accreditation is independently assessed rather than self-declared, covering technical capability, ethical conduct and quality of delivery. Your engagement follows the methodology and standards it certifies.

Application Security Testing FAQs

What Is Application Security Testing?

Application security testing is the process of identifying vulnerabilities in web applications, mobile applications and APIs. It examines how an application handles authentication, permissions, user input, data, sessions and communications. Testing can combine automated scanning with manual penetration testing to identify weaknesses that could be exploited by an attacker. 

What is the difference between application security testing and penetration testing?

Application security testing is the broader practice of assessing application security using methods such as automated scanning, code analysis and manual testing. Application penetration testing is a hands-on assessment in which consultants simulate attacks against a running application to identify exploitable vulnerabilities.

 

What is tested during a web application penetration test?

Testing may cover authentication, session management, user permissions, input validation, business logic, APIs, file uploads, encryption, data exposure and application configuration.

Do you test mobile applications?

Yes. Integrity360 tests both iOS and Android applications, including application packages, local data storage, authentication, API communication, transport security and platform-specific controls.

Can Integrity360 test APIs?

Yes. API security testing can assess authentication, authorization, object-level access controls, input handling, rate limiting, data exposure and configuration weaknesses.

Will we receive remediation guidance?

Yes. Findings should include evidence, risk ratings, technical impact and practical recommendations to help development teams resolve vulnerabilities.

Can vulnerabilities be retested?

Yes. Retesting can confirm whether identified vulnerabilities have been remediated successfully and provide an updated record of their status.

When should an application be security tested?

Testing should be performed before significant releases, after major changes, when introducing new APIs or integrations, and periodically as part of an ongoing application security program.
