Web Application Penetration Testing
Your web application is the foundation of your business – it serves customers, processes data and connects with critical systems. But is it secure enough? Cybercriminals exploit even the smallest vulnerabilities to gain control, access sensitive data or disrupt application functionality.
Web application penetration testing allows you to detect and fix vulnerabilities before attackers do. Through controlled attack simulations, we verify whether your application can withstand real-world threats and ensure it meets the highest security standards.
Benefits of Web Application Testing
Detection of critical vulnerabilities
– we check for issues such as SQL Injection, XSS, and authentication flaws.
User data protection
– we help you prevent data leaks and protect customer privacy.
Regulatory compliance
– testing supports compliance with standards such as OWASP, GDPR, and ISO 27001.
Reduced risk of cyberattacks
– we identify and eliminate weaknesses before they are exploited.
What Is Web Application Penetration Testing?
Penetration testing simulates real-world attacks on your web application, conducted by cybersecurity experts. The goal is to assess your system’s resistance, uncover potential threats, and deliver clear, actionable remediation guidance.
During the test, we analyse:
- Login and authentication attacks – brute-force attempts, logic flaws, and account takeover risks.
- Database security – including SQL Injection and other code injection techniques.
- XSS vulnerabilities – the risk of injecting malicious scripts into web pages.
- API protection – we assess whether your application’s communication interfaces are securely implemented.
With our support, you’ll gain full control over the security posture of your application.
We rely on leading industry tools and best practices, aligned with global standards:
- OWASP ZAP – for automated and manual vulnerability scanning in web applications.
- Burp Suite – advanced traffic analysis and in-depth vulnerability detection.
- SQLmap – used for detecting and exploiting SQL Injection vulnerabilities.
- SonarQube – source code quality and security analysis.
All tests are conducted in accordance with the OWASP Testing Guide, ensuring the highest level of auditing quality.
Frequently Asked Questions
Can the tests impact my application’s performance?
No – testing is performed in a controlled manner to avoid disruptions in your production environment. If live systems are involved, we use cautious exploratory techniques.
How often should I perform web app penetration tests?
We recommend testing at least once a year, as well as after every major update. It’s also best to test before launching an application into production.
Do you test only the deployed application, or also the source code?
We can test both. Our approach includes black-box and grey-box testing of the live application, and optionally source code analysis to find deeper, hidden flaws.
What kind of report will I receive after the test?
You’ll receive a detailed report listing identified vulnerabilities, risk assessments, and remediation recommendations. We can also support your team with implementing fixes and re-testing security controls.
