Application Penetration Tests

Review your APIs, mobile applications, customer kiosks and thick clients for vulnerabilities

Bastion’s skilled penetesters can test a range of applications to identify any vulnerabilities, insecure storage, or weaknesses in your authentication, configuration, implementation, or data flows. We can help you with

API penetration testing
Kiosk penetration testing (physical and software components)
Mobile application security review (Android and iOS)

Identify vulnerabilities in your application

How secure are your applications from real-world attacks? Our application penetration testing simulates malicious behavior to uncover flaws before threat actors do.

Find the flaws before attackers do

Go beyond automated scans

Our expert-led testing digs deep into your application’s logic, roles, and input handling which automated tools often miss. Starting from a zero-access perspective, we simulate escalating privileges, tampering with data, and breaking access controls.
