Web Application VAPT
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.

Web Application VAPT — 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

Whether you’re shipping a new product, responding to a customer security questionnaire, or preparing for SOC 2 or ISO 27001, a rigorous web application penetration test gives you evidence you can stand behind. Talk to our team about scoping an assessment around your stack and timelines.
Frequently Asked Questions
What is the difference between a vulnerability assessment and a penetration test?+
A vulnerability assessment finds and lists potential weaknesses, largely with tooling. A penetration test goes further: a human safely exploits those weaknesses to prove which are real and what the business impact would be. Our Web Application VAPT combines both, so you get breadth and verified depth.
Will testing affect our live application or users?+
We design engagements to avoid disruption. Higher-risk tests are scheduled in agreed windows or run against a staging environment, and we keep a direct line to your team throughout so anything unexpected is caught immediately.
How long does a web application penetration test take?+
Most assessments run one to three weeks depending on the size and complexity of the application. We scope and agree a timeline with you before any testing begins.
Do you re-test after we fix the issues?+
Yes. Remediation re-testing is included — once you have applied fixes, we verify them and issue an updated report confirming the risks are closed.
Can you help us meet SOC 2, ISO 27001 or PCI DSS requirements?+
Absolutely. Our reports map findings to these frameworks, and our GRC team can support the wider certification effort end to end.

API Security Testing (API VAPT)
APIs power your apps, partners and integrations — and they’re now the most attacked part of most modern platforms. Because APIs expose business logic directly, a single broken authorisation check can leak every customer’s data. Aesparrow’s API Security Testing (API VAPT) is built around the OWASP API Security Top 10 and goes deep on the flaws automated tools consistently miss: broken object-level authorisation (BOLA/IDOR), mass assignment, and business-logic abuse.
Red Team Assessment
A penetration test answers "is this system vulnerable?" A red team assessment answers a harder, more valuable question: "if a determined attacker targeted our business, would we detect and stop them?" Aesparrow’s red team runs a goal-based, adversary-style simulation across people, process and technology — emulating real threat actors to test your detection and response, not just your patch levels.
Mobile Application VAPT
Your mobile app runs on devices you do not control, which makes it a uniquely exposed part of your attack surface. Aesparrow’s Mobile Application VAPT tests Android and iOS apps against the OWASP Mobile Top 10 — covering insecure data storage, weak cryptography, broken authentication and the client-server APIs behind them — using both static and dynamic analysis on real devices.
