Web Application Security Testing (WAPT)


What is Web Application Penetration Testing (WAPT)?

Enterprise Security Breaches Demand Immediate Action

Web Application Security Testing is essential to protect business-critical applications from cyber-attacks that exploit coding flaws, misconfigurations, and insecure design. As web applications are one of the most common attack vectors, organisations must proactively assess and secure them against evolving threats.

At Cybernetic Global Intelligence (CGI), we provide comprehensive web application penetration testing and vulnerability assessment services delivered by certified ethical hackers, aligned with OWASP, ISO/IEC 27001, PCI DSS, NIST Cybersecurity Framework (CSF), and PTES standards.

Modern development cycles often prioritise speed and functionality over security, leaving applications vulnerable to attack. Whether you are developing a custom business application or using platforms such as WordPress, Joomla, ZenCart, or other web-based systems, our web application security assessments identify exploitable vulnerabilities before attackers do.

What Our Web Application Security Testing Covers

Our testing evaluates applications across the full attack surface, including:

  • OWASP Top 10 vulnerabilities
  • Authentication and access control weaknesses
  • Session management and cookie security
  • Input validation and injection flaws (SQLi, XSS, CSRF)
  • API and backend service security
  • Business logic vulnerabilities
  • Secure configuration and deployment issues

Why Web Application Security Matters

A compromised web application can result in stolen session IDs and cookies, unauthorised account access, sensitive data exposure, database breaches, malware injection, website defacement, and reputational damage. Web application penetration testing provides a realistic assessment of how attackers could exploit these weaknesses and the potential business impact.

Web application security testing is a critical component of a mature cyber security, vulnerability management, and compliance programme, supporting requirements under ISO 27001, PCI DSS, APRA CPS 234, Essential Eight, and SOCI Act.


Benefits

Benefits of Conducting a Web Application Cyber Security Assessment

A Web Application Cyber Security Assessment helps organisations proactively identify and remediate security weaknesses in web-based applications before they are exploited by cyber criminals. As web applications are a primary attack vector, regular security testing is essential to protecting sensitive data, maintaining compliance, and reducing business risk.

Identify Critical Web Application Vulnerabilities

Web application security assessments uncover OWASP Top 10 vulnerabilities, insecure coding practices, misconfigurations, and logic flaws that may not be detected during development or routine testing.

Prevent Data Breaches and Application Compromise

By identifying exploitable weaknesses early, organisations reduce the risk of unauthorised access, session hijacking, account takeover, database breaches, and malicious code injection.

Validate Secure Development Practices

Web application penetration testing helps validate whether secure coding standards, DevSecOps controls, and application security measures are effective across development and production environments.

Support Regulatory and Compliance Requirements

Web application cyber security assessments support compliance with ISO/IEC 27001, PCI DSS, NIST Cybersecurity Framework, OWASP, APRA CPS 234, Essential Eight, and SOCI Act by demonstrating proactive vulnerability management and risk mitigation.

Protect Brand Reputation and Customer Trust

A secure web application helps protect customer data, business operations, and organisational reputation, reducing the likelihood of public-facing incidents and regulatory scrutiny.

Improve Risk Visibility for Executives and Boards

Risk-based reporting provides clear, actionable insights for senior management and boards, enabling informed decisions on application security investments and risk acceptance. Identifying and fixing vulnerabilities early is significantly more cost-effective than responding to a post-breach incident, regulatory penalties, or operational disruption.

Strengthen Overall Cyber Security Posture

Regular web application security assessments contribute to a mature vulnerability management and penetration testing programme, ensuring applications remain resilient as threats and technologies evolve.

  • Threat Modelling methodologies (STRIDE and DREAD) – Systematically identifying, categorising, and prioritising application security threats
  • OWASP Software Assurance Maturity Model (OpenSAMM) – Assessing and improving secure software development and governance practices
  • Open-Source Security Testing Methodology Manual (OSTMM) – Ensuring a comprehensive and methodical security testing approach
  • Web Application Security Consortium (WASC) Threat Classification – Enhancing vulnerability coverage and classification accuracy

What Our Methodology Delivers

By combining manual ethical hacking techniques with automated vulnerability assessment tools, our web application penetration testing methodology delivers:

  • Identification of OWASP Top 10 and business logic vulnerabilities
  • Validation of authentication, authorisation, and session management controls
  • Assessment of input validation, API security, and backend services
  • Risk-based prioritisation aligned to business impact and exploitability
  • Actionable remediation guidance for development and IT teams

Each engagement concludes with a clear, executive-ready web application security report, providing both technical detail and board-level risk visibility.

White Box Testing

White Box Testing

White Box Testing, also known as Source Code Security Testing, is a comprehensive web application security assessment conducted with full visibility into an application’s source code, system architecture, APIs, and internal logic. This approach enables a deeper and more accurate identification of security weaknesses that may not be visible through external or black box testing alone.

At Cybernetic Global Intelligence (CGI), our White Box Testing services are delivered by certified ethical hackers and application security specialists to identify vulnerabilities arising from insecure coding practices, logic flaws, weak error handling, and insecure integrations—before applications are released into production.

White Box Testing is particularly effective in identifying internal threat vectors and attack scenarios where adversaries may have partial or full knowledge of an application’s internal workings, such as compromised developers, insider threats, or advanced persistent attackers.

Cybersecurity testing

Why White Box Testing Is Critical

Application vulnerabilities can exist not only within custom code but also in third-party libraries, frameworks, APIs, and software components. Conducting White Box Testing allows organisations to identify and remediate security flaws early in the software development lifecycle (SDLC), reducing the risk of exploitation post-deployment.

Key Advantages of White Box Testing

Clean and Secure Code

White Box Testing enables detailed source code review to identify insecure coding patterns, poor error handling, hard-coded credentials, insecure dependencies, and logic flaws that could be exploited by attackers.
Early Vulnerability Detection
Identifying vulnerabilities during development significantly reduces the cost and impact of remediation compared to fixing issues after an application is publicly exposed.

Professional, Independent Assessment

Engaging external web application security experts ensures an unbiased, in-depth assessment conducted using advanced application security tools, including static code analysers, debuggers, and fault-injection techniques that may not be available to internal teams.

Compliance and Best-Practice Alignment

White Box Testing supports compliance with OWASP, ISO/IEC 27001, PCI DSS, NIST Cybersecurity Framework, and Secure SDLC best practices, providing assurance to auditors, regulators, and stakeholders.
Each White Box Testing engagement concludes with a clear, risk-rated report outlining identified vulnerabilities, exploitability, business impact, and prioritised remediation recommendations for development and security teams.

Black Box Testing

Black Box Testing

Black Box Testing is a form of web application penetration testing that evaluates the security of an application from the perspective of an external attacker with no prior knowledge of the application’s source code, architecture, or internal logic. This approach accurately simulates real-world cyber-attacks to determine how a malicious actor could compromise your web application.

At Cybernetic Global Intelligence (CGI), our Black Box Testing services are conducted by certified ethical hackers using advanced manual and automated techniques to rigorously test applications against a wide range of attack scenarios. By treating the application as a “black box,” we deliver an unbiased, attacker-centric assessment that mirrors how real cyber criminals target publicly accessible systems.

Black Box Testing is particularly effective for identifying externally exploitable vulnerabilities, misconfigurations, and weaknesses that may be overlooked during development or internal testing.
