Application Penetration Testing Services

Our application penetration tests attempt to exploit web apps, APIs, or thick clients using the same tools and techniques that attackers do. Our team conducts an end-to-end assessment ensuring critical vulnerabilities and logic flaws are discovered – guided by the OWASP Top 10.

Application Penetration Testing

Get expert insights into how your apps can be exploited, so you can make them more secure.

An Application Penetration Test assesses the security of your web application, API, or thick client against the same tools and techniques leveraged by attackers. Our team of highly experienced consultants will dive deep into the inner workings of applications uncovering vulnerabilities and logic flaws.

As a core part of our methodology, we follow the OWASP Testing Guide to test for the OWASP Top 10 vulnerabilities: injection, broken authentication, sensitive data exposure, XML external entities (XXE), broken access control, security misconfiguration, cross-site scripting (XSS), insecure deserialization, using components with known vulnerabilities, and insufficient logging and monitoring.

Application Penetration Testing highlights:

  • Expert collaboration: Collaborate with our consultants and receive expert guidance to create the right assessment to meet your desired outcomes.
  • Third-party validation: Use our reports to demonstrate due diligence, as well as compliance with application security requirements.
  • Combine with other services: Bundle or combine our APT service with any of our other services to add coverage depth or deeper analysis where required.
  • Multiple delivery models: Choose from continuous delivery or point-in-time engagements to meet your unique needs.
App Pen Testing Methodology Transparent

Peek under the hood

Explore Our Application Penetration Testing Methodology

Our application penetration testing methodology identifies application security vulnerabilities by combining automated and manual testing techniques. Assessments begin by crawling and footprinting the application. Next, the assessment team conducts vulnerability scans with automated tools and manually validates the results. Finally, the team manually identifies and exploits implementation errors and business logic. Check out our complete methodology for more details on what to expect.

Achieve your security goals

Go beyond an automated scan. Get intelligent insights that strengthen security and improve compliance.


Custom tailored assessments

Wherever you fall on the spectrum of time-boxed to comprehensive testing, we always test for the OWASP Top 10 which includes: injection, broken authentication, sensitive data exposure, XML external entities (XXE), and more.


Go beyond automated dynamic scanning

Our highly skilled, creative, and experienced consultants discover business logic and privilege escalation flaws that can only be found manually. We go beyond automated dynamic scans to ensure critical vulnerabilities don't fly under the radar.


Embed security into the SDLC

In addition to validating the security of an application from a compliance perspective, application penetration tests can be used throughout an Agile or DevSecOps lifecycle to find and fix flaws before they get ‘inherited’ into production. We’ll find vulnerabilities in places you never thought to look.


Assess material impacts to the business

We simulate a real-world attack on the apps and services most critical to your business. With an attacker perspective, you can demonstrate the true business impact of vulnerabilities while also prioritizing the most critical ways you can secure the app environment.


Augment with our ASA and Threat Modeling service

Pair with an Architecture Security Assessment (ASA) and our Threat Modeling service for an in-depth assessment of the threats your application faces. By discovering your app’s full attack surface area, you’ll be able to secure it against targeted attacks.


Actionable reports, not canned PDFs

Our high-quality reporting goes above and beyond static risk ratings and generic scoreboards. In addition to being fully customized to your application, your organization, and your desired outcomes, our reports offer actionable security guidance.


Assessments performed by experts

Our consultants have decades of experience testing apps and rely on industry standard methodologies. We do this to ensure breadth of coverage and depth of testing.

“I wanted to choose a company with deep technical skills that clearly excelled at offensive security. I didn’t want to simply ‘check a box’ when it came to security.”
