OWASP Top 10 Coverage & Advanced Testing Methodology

Praxis-Q performs rigorous Web Application Security Testing covering the complete OWASP Top 10: injection attacks, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfiguration, XSS, insecure deserialization, using components with known vulnerabilities, and insufficient logging. Our dual-approach methodology combines automated DAST (Dynamic Application Security Testing) with hands-on manual penetration testing to uncover logic flaws, cryptographic weaknesses, and business-context vulnerabilities that scanners miss. API security testing—including REST, SOAP, and GraphQL endpoints—is included standard. Every finding receives CVSS severity scoring and proof-of-concept documentation for streamlined remediation.

UK Compliance & Regulatory Alignment

Web application vulnerabilities directly impact your UK GDPR, ICO, and FCA operational resilience obligations. Praxis-Q's testing framework aligns with NCSC Cyber Essentials, PCI DSS (payment card security), and SOC 2 controls, ensuring discovered flaws map directly to your compliance requirements. Our India-based security engineers maintain UK data protection standards and deliver reports that satisfy auditor expectations across financial services, healthcare, e-commerce, and public sector organizations. Regular testing cycles demonstrate ongoing security due diligence—critical for regulatory assessments, insurance underwriting, and customer trust.

Fast-Track Delivery & Actionable Remediation

Praxis-Q's standard 5–7 day engagement, with 15–20 day fast-track options, accelerates vulnerability discovery without compromising depth. Our scoping process—covering application scope, environments, authentication models, and API inventory—ensures efficient reconnaissance and targeted testing. Detailed reports include vulnerability descriptions, attack scenarios, severity ratings, and developer-friendly remediation steps. Business stakeholders receive executive summaries linking findings to business risk, while technical teams get step-by-step fix guidance and code examples, enabling swift patching cycles.

Authentication, Session Management & Business Logic Testing

Beyond baseline OWASP scanning, Praxis-Q stress-tests authentication mechanisms, session handling, token management, and role-based access controls to reveal privilege escalation and account takeover risks. Business logic testing identifies flaws in workflows, payment flows, user registration, and state validation that break application intent. Grey-box testing—conducted with limited user credentials—simulates insider threats and realistic attack progressions. This contextual approach prevents false negatives and uncovers high-impact vulnerabilities that directly threaten customer data, revenue, and regulatory standing.

Global Delivery with India-Based Expertise

Praxis-Q combines India's deep security engineering talent with global delivery standards and UK/EU compliance expertise. Our distributed team ensures round-the-clock progress, competitive pricing, and access to specialized researchers for advanced vulnerability analysis. From startup MVPs to enterprise multi-tenant SaaS platforms, we tailor engagement scope and timeline to your development velocity and risk appetite. Post-report, we support remediation verification, retesting, and continuous security integration guidance.

Frequently Asked Questions

What is included in web app pen testing?
OWASP Top 10, authentication testing, session management, input validation, business logic, API security, and cryptography testing.
Black box vs grey box testing?
Black box simulates an external attacker with no credentials. Grey box provides limited credentials (e.g., regular user) for more realistic testing. We offer both.
What vulnerability types does Praxis-Q's Web Application Security Testing cover?
We cover the complete OWASP Top 10: injection (SQL, NoSQL, LDAP), broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfiguration, cross-site scripting (XSS), insecure deserialization, using components with known vulnerabilities, and insufficient logging/monitoring. We also test APIs, business logic, cryptography, and session management.
How does Praxis-Q's testing comply with UK GDPR and ICO requirements?
Our testing methodology aligns with UK GDPR data protection principles, ICO guidance on security by design, and NCSC Cyber Essentials. We identify vulnerabilities that could lead to unauthorized data access or breach notification obligations, deliver findings with privacy impact assessment context, and provide remediation timelines supporting your Data Protection Impact Assessment (DPIA) and compliance evidence.
What's the difference between black-box and grey-box testing, and which should we choose?
Black-box testing simulates an external attacker with zero knowledge or credentials, validating perimeter defenses. Grey-box testing provides limited user credentials (regular user, admin), revealing privilege escalation and insider-threat scenarios. Praxis-Q offers both; many organizations run grey-box for comprehensive coverage. Your choice depends on threat model, compliance requirements, and budget.
Are APIs included in Web Application Security Testing?
Yes. Praxis-Q includes REST, SOAP, GraphQL, and proprietary API security testing as standard. We test authentication, authorization, rate limiting, input validation, data exposure, and business logic flaws within APIs. Modern applications rely heavily on APIs; comprehensive testing ensures backend security and prevents data leakage through integration points.
How quickly does Praxis-Q deliver Web Application Security Testing reports?
Standard delivery is 5–7 business days post-scoping. Praxis-Q offers 15–20 day fast-track options for organizations with urgent timelines. Report scope includes detailed vulnerability descriptions, proof-of-concept exploits, CVSS severity scores, developer-friendly remediation steps, and executive summaries linking findings to business and compliance risk.
Does Praxis-Q support retesting and remediation verification after fixing vulnerabilities?
Yes. Post-report remediation support and retesting are available. After your team applies fixes, Praxis-Q conducts verification testing to confirm vulnerabilities are resolved, document evidence for auditors, and advise on security control integration and continuous testing strategies aligned with your development lifecycle.
