Business Logic & Data Protection – Preventing abuse of application workflows, securing data at rest and in transit.

FAQ – Web Application Penetration Testing

An application penetration test evaluates the security of your web, mobile, or API applications by identifying vulnerabilities such as authentication flaws, injection attacks, misconfigurations, and access control weaknesses. Our tests follow industry-standard methodologies, including OWASP Top 10 and NIST guidelines, to ensure comprehensive risk assessment.

The duration of a penetration test depends on the application’s size and complexity. Most tests take between one to three weeks, including the testing phase and report generation. For larger applications or those with complex integrations, additional time may be required.

Pricing starts at $5,000. Contact us for a tailored estimate.

To begin testing, we need a general understanding of your application, including how it’s built, how users access it, and its key functionalities. If available, documentation on system architecture, authentication methods, API endpoints, and user roles will help ensure a thorough and efficient test.

Yes, regular testing is highly recommended, especially for applications that frequently release updates. Many organizations perform tests quarterly or after significant code changes to ensure ongoing security.

Vulnerability scanning is an automated process that identifies potential security weaknesses, while penetration testing is a manual, in-depth assessment performed by security experts to actively exploit vulnerabilities and assess their real-world impact.

No, penetration tests are designed to be safe and minimally disruptive. We coordinate testing schedules and follow best practices to prevent downtime. If needed, we can conduct tests in a staging environment to avoid any impact on production systems.

After testing, you’ll receive a detailed report outlining vulnerabilities, risk levels, and recommended remediation steps. We also offer a complimentary retest to verify that the issues have been resolved and ensure your application remains secure.

While penetration testing is not a strict requirement for SOC-2 or HIPAA, it is commonly used to verify the effectiveness of security controls and identify vulnerabilities that could impact compliance. Our penetration tests help assess risks related to data protection, access controls, and system security, providing valuable insights for organizations preparing for compliance audits.
