Quick Answer: A web application security assessment combines automated scanning with manual testing to identify OWASP Top 10 vulnerabilities, business logic flaws, authentication bypasses, and insecure APIs. Professional assessments include authenticated testing across multiple user roles, a technical report with CVSS scores, and a complimentary retest of remediated findings.
What Is a Web Application Security Assessment?
A web application security assessment (also called a web app penetration test or WAPT) is a structured, expert-led evaluation of your web application’s security posture. Security consultants attempt to exploit vulnerabilities in your application — the same way a real attacker would — to identify weaknesses before they’re discovered and abused.
Unlike automated scanning, a professional assessment combines automated tooling with manual testing techniques to uncover complex vulnerabilities including business logic flaws, authentication bypasses, insecure API endpoints, and injection vulnerabilities that scanners routinely miss.
What Does a Web Application Security Assessment Cover?
OWASP Top 10 Testing
The OWASP Top 10 represents the most critical web application security risks. Every assessment covers:
- Injection flaws (SQL, NoSQL, LDAP, OS command)
- Broken Authentication and session management
- Cross-Site Scripting (XSS)
- Insecure Direct Object References (IDOR)
- Security Misconfiguration
- Sensitive Data Exposure
- XML External Entity (XXE)
- Broken Access Control
- Cross-Site Request Forgery (CSRF)
- Using Components with Known Vulnerabilities
Business Logic Testing
Automated scanners cannot test business logic. Our consultants manually probe your application workflows — payment flows, role-based access, multi-step transactions — to find flaws that only a human understands in context.
API Security Testing
REST and GraphQL APIs are assessed for authentication weaknesses, rate limiting, data exposure, and injection vulnerabilities. API endpoints are often under-tested and represent a growing attack surface.
Authenticated Testing
Testing with valid user credentials (across multiple privilege levels) reveals vulnerabilities that unauthenticated scanners cannot reach — privilege escalation, IDOR, insecure account management, and broken access control issues.
Who Needs a Web Application Security Assessment?
- SaaS companies before enterprise customer security reviews
- Fintech and banking applications handling financial transactions
- Healthcare platforms handling patient data (HIPAA, My Health Records)
- E-commerce sites before peak trading periods
- Government and critical infrastructure web portals
- Any company releasing a new application or major feature
Our Web Application Assessment Methodology
eShield Consulting follows the OWASP Testing Guide (OTG) and PTES (Penetration Testing Execution Standard) methodologies:
- Reconnaissance: Application mapping, technology fingerprinting, attack surface enumeration
- Automated scanning: Burp Suite Pro, OWASP ZAP, Nikto
- Manual testing: Authentication, authorisation, input validation, session management
- Exploitation: Confirmed proof-of-concept for valid findings
- Reporting: Executive summary + technical findings with CVSS scores and remediation guidance
- Retest: Verification of remediated vulnerabilities at no extra cost

Frequently Asked Questions
How long does a web application assessment take?
A typical web application assessment takes 3–10 business days depending on application complexity, number of user roles, and API endpoint count. A simple marketing site with a contact form takes 2–3 days; a complex SaaS platform with multiple roles and extensive APIs may take 8–10 days.
Do you provide a retest after remediation?
Yes — all eShield web application assessments include a complimentary retest of all confirmed findings within 90 days of the original report delivery.
What deliverables will we receive?
You receive an Executive Summary (suitable for board/management), a Technical Report with full finding details, CVSS scores, evidence screenshots, and step-by-step remediation guidance. We also provide an attestation letter for use with customers and procurement teams.
