OWASP Security Testing & Vulnerability Assessment

I will conduct an OWASP Top 10-based security vulnerability assessment of your web application — covering SQL injection, Cross-Site Scripting (XSS), broken authentication, sensitive data exposure, XML External Entity injection, broken access control, security misconfiguration, insecure deserialization, known vulnerable dependencies, and insufficient logging — using a combination of automated scanning (OWASP ZAP, Burp Suite Community) and manual verification, and delivering a security assessment report with findings, CVSS severity scores, and remediation guidance. Security testing conducted only with automated scanners produces high false positive rates and misses the business logic vulnerabilities, broken access control issues, and authentication bypass paths that require manual verification to identify; this service combines both approaches.

The assessment covers automated scanning with OWASP ZAP, manual verification of scanner findings, manual testing for authentication and session management weaknesses, authorisation testing (IDOR and privilege escalation), input validation and injection testing, sensitive data exposure in API responses and error messages, and a security assessment report with CVSS score, severity rating, reproduction steps, and specific remediation recommendations for every confirmed finding.

Designed for development teams preparing for a security review, organisations handling personal or financial data, and businesses seeking Cyber Essentials or ISO 27001 certification who need a web application security assessment conducted by a qualified tester.
