Web Application Penetration Testing
Your web application is the front door to your business. We test it the way an attacker would — from both sides of the login screen.
Where most organizations actually lose data
An old admin panel nobody remembered to lock down. An access check that only runs on the happy path. A business rule that makes sense until someone deliberately breaks it. These are the things that actually get exploited, and they're exactly what automated scanning tends to walk right past. CyberMindX tests customer-facing apps, internal portals, and admin consoles the way someone trying to get in without permission actually would — logged in and logged out.
We open with a conversation to pin down what matters most in your application, then map out everything it exposes before touching a single input field. From there, the actual testing is done by hand: every form, every role, every place the application changes state. Automated tools run in the background for breadth, but the findings that actually matter — the ones that put the business at risk — come out of that manual work. When testing wraps, so does your fix window, and then we come back and check it for free.
How we run a web application engagement
Scope & Threat Model
Before we run a single test, we put in writing exactly what's being tested, what's out of bounds, and what a realistic attacker would actually be after in your application.
Reconnaissance & Surface Mapping
We catalogue every endpoint the application actually exposes — including the ones that never made it into the documentation — so nothing catches us off guard once testing starts in earnest.
Manual-Led Discovery
Someone sits down and works through every input, every user role, and every place access should be denied but might not be — logged in and logged out. Scanners add breadth alongside this, but they don't drive it.
Exploitation & Validation
We don't report a theory — every finding we keep gets proven with a safe proof-of-concept, and where issues link together into something worse, we walk that full path without putting your production data at risk.
Reporting & Free Retest
The report is written for the people who have to fix things — reproduction steps, the actual payloads, and a fix at the code level for each finding. Patch it, and we'll check our own work at no extra cost.
Scope of testing
- OWASP Top 10 (2021) and ASVS-aligned controls
- Authentication, session, and SSO integrity
- Authorization boundaries — IDOR, privilege escalation, tenant isolation
- Business-logic flaws specific to your application
- Injection — SQL, NoSQL, command, template
- Server-side request forgery, deserialization, file upload abuse
- Client-side risks — XSS, CSRF, and browser-side data exposure
What we find most often
Broken object-level access checks
Swap an ID in the request and the server hands back someone else's record anyway — the access-control check simply isn't there. This class of bug shows up constantly and rarely needs anything more than a browser to exploit.
Injection in the places you'd least expect
Straightforward SQL injection is largely a solved problem, but it resurfaces in unexpected corners — inside ORM query builders, second-order lookups, or wherever a developer had to drop down to raw query syntax.
Client-side script injection
Frameworks have mostly closed the door on classic reflected and stored script-injection bugs, which pushes the remaining risk into the client-side bundle itself — exactly where a scanner is least likely to look.
Small issues that add up to a big one
A handful of findings that look unremarkable on their own can, put together in the right order, add up to full control of another user's — or another customer's — account.

Buyer questions, answered honestly
How long does a web application penetration test take?
Most engagements run 5–10 working days depending on the number of roles, user flows, and API endpoints in scope. We confirm the exact timeline during scoping.
What does the deliverable look like?
An executive summary for stakeholders, plus an engineer-grade technical report with reproduction steps, payloads, and suggested fixes for every finding.
Does the engagement cover the OWASP Top 10?
Yes, along with business-logic and authorization testing that automated scanners and checklist-only assessments typically miss.
Is authentication and authorization tested?
Yes — including session handling, SSO integrations, and role-based access control across every user type in scope.
Do you provide a free retest?
Yes. Every finding gets a free retest once your team has shipped a fix, at no additional cost.
Ready to scope this engagement?
We'll align on goals, rules of engagement, and timeline within one working day.
