Web Application VAPT & Penetration Testing
Protect what matters with Web Application VAPT & Penetration Testing
Your web application is the front door to your business — and the first thing an attacker probes. Aesparrow’s Web Application VAPT (Vulnerability Assessment and Penetration Testing) combines deep manual testing with trusted tooling to find the flaws that automated scanners miss: broken access control, business-logic abuse, injection, and authentication weaknesses. You get a clear, prioritised picture of what a real attacker could do, and exactly how to fix it before it costs you.
We test the way an adversary actually works — chaining small weaknesses into real impact — not by handing you a raw scanner dump. Every finding is verified by a human, rated by genuine business risk, and written up so your developers can reproduce and remediate it quickly. When you’ve fixed the issues, we re-test them at no extra cost so you can prove the risk is closed to customers, auditors, and your board.
- Certified senior practitioners
- Audit-ready reporting
- Free re-test included

Web Application VAPT & Penetration Testing — done right, the first time.
Senior practitioners. Verified findings. Free re-test.
Overview
Web Application VAPT is a controlled, authorised simulation of the attacks a real adversary would launch against your application and its APIs. We map the attack surface, hunt for vulnerabilities across authentication, authorisation, input handling and business logic, safely prove which are exploitable, and quantify the impact. The result is an evidence-based view of your true security posture — not a checklist.
What we test for
Aligned to the OWASP Top 10 and OWASP ASVS, plus the deeper checks that separate a real pentest from a scan.
- Injection — SQL, NoSQL, command and template injection
- Cross-Site Scripting (XSS) — reflected, stored and DOM-based
- Broken access control / IDOR — horizontal and vertical privilege escalation
- Authentication & session management — weak flows, token handling, MFA bypass
- Server-Side Request Forgery (SSRF) — and cloud metadata exposure
- CSRF & input validation — state-changing request abuse
- Insecure file upload — and unrestricted content handling
- Business logic abuse — workflow, pricing and rate-limit bypass
- Security headers & misconfiguration — CSP, HSTS, cookie flags
- API integration flaws — the endpoints behind your UI
Our testing methodology
A blend of manual expertise and automation across a structured, repeatable process.
Scoping & recon
We agree targets, rules of engagement and timelines, then map the full attack surface.
Automated discovery
Tuned scanning to surface the obvious quickly and free time for manual depth.
Manual exploitation
Certified testers verify and safely exploit findings to prove real-world impact.
Business logic testing
We probe workflows, authorisation and abuse cases unique to your application.
Reporting & triage
Prioritised findings with evidence, CVSS and clear remediation guidance.
Remediation re-test
We re-test your fixes and issue an updated report at no extra cost.
Framework mapping
Every assessment maps cleanly to the standards your auditors and customers expect.
- OWASP Top 10 — the industry baseline for web risk
- OWASP ASVS — verification standard for depth and rigour
- NIST SP 800-115 — technical testing methodology
- CIS Benchmarks — secure configuration baselines
- MITRE ATT&CK — techniques mapped for red-team-style engagements
Deliverables
