Web application security. Tested by experts.
Your web applications and APIs are your most exposed attack surface. Our certified testers go beyond automated scanning to find the logic flaws, authentication weaknesses, and injection vulnerabilities that put your business and your customers at risk.
Every layer of your web application. Thoroughly tested.
Our web application testing goes beyond automated scanners. We combine tooling with manual testing to find vulnerabilities that matter.
OWASP Top 10 Assessment
Comprehensive testing against the OWASP Top 10 vulnerabilities including injection flaws, broken authentication, sensitive data exposure, and security misconfigurations.
API Security Testing
REST, GraphQL, and SOAP API assessments covering authentication, authorisation, rate limiting, data exposure, and business logic vulnerabilities.
Authentication and Session Testing
In-depth testing of login mechanisms, session management, password policies, multi-factor authentication bypass, and account enumeration vulnerabilities.
Business Logic Testing
Manual testing of application workflows to identify logic flaws that automated scanners miss, including price manipulation, workflow bypass, and privilege escalation.
Infrastructure and Configuration Review
Assessment of web server configuration, TLS settings, HTTP security headers, error handling, and information disclosure vulnerabilities.
Source Code Review
Optional manual source code review to identify vulnerabilities at the code level, including insecure cryptography, hardcoded credentials, and unsafe deserialization.
A structured methodology. Actionable results.
Every web application test follows a rigorous process. You know exactly what we are doing, when we are doing it, and what you will receive at the end.
Scoping and Rules of Engagement
We define the target application, authentication levels, test accounts, and any out-of-scope areas. A signed rules of engagement document protects both parties.
Reconnaissance and Mapping
Passive and active reconnaissance to map the application surface, enumerate endpoints, identify technologies, and understand the authentication model.
Vulnerability Discovery
Combination of automated scanning and manual testing to identify vulnerabilities across all OWASP categories and application-specific logic flaws.
Exploitation and Impact Demonstration
Controlled exploitation of confirmed vulnerabilities to demonstrate real-world impact, including data access, account takeover, and privilege escalation.
Reporting and Risk Rating
A clear report with executive summary, technical findings, CVSS risk ratings, and step-by-step remediation guidance for your development team.
Remediation Support and Retest
We remain available during your remediation window and provide a free retest of all critical and high findings once fixes are deployed.
