Application Security

Web Application Penetration Testing

Manual testing of your web application the way an attacker actually approaches it — authentication, access control, business logic, and every input that touches your data, not just a scan of known signatures.

Scope

What We Test

Coverage is mapped to the OWASP Testing Guide and OWASP ASVS, tailored to your application's actual functionality.

Authentication & Session Management

Login flows, password reset, multi-factor bypass, session fixation, token handling, and account lockout logic.

Broken Access Control

Insecure direct object references, horizontal and vertical privilege escalation between user roles and accounts.

Injection Flaws

SQL injection, server-side template injection, command injection, and XSS across every user-controlled input.

Business Logic

Price manipulation, workflow step bypass, coupon and quantity abuse, and race conditions in critical flows.

File Handling

Upload restrictions, path traversal, insecure deserialization, and server-side file processing.

Security Misconfiguration

CSRF protection, security headers, verbose error messages, and exposed admin or debug interfaces.

Sensitive Data Exposure

Data in transit and at rest, API responses that over-share fields, and client-side secret leakage.

Server-Side Request Forgery

Internal network and metadata endpoint access through application-initiated requests.

Underlying APIs

Any API the application calls is tested too — see API Penetration Testing for standalone API-only engagements.

Approach

Grey-Box, By Default

Why grey-box

Most real attackers eventually operate with some level of access — a leaked credential, a compromised account, or a purchased subscription. Testing with one or two low-privilege test accounts finds access-control and business-logic flaws a fully black-box test would miss, without the added cost of a full source-code review.

Tooling & technique

Burp Suite Professional and purpose-built scripts drive coverage and evidence capture; every meaningful finding is manually verified and exploited to confirm real impact before it goes in the report — no unverified scanner output.

FAQ

Web Application Testing Questions

Black-box or grey-box?

We default to grey-box (one or two test accounts per role) because it finds far more real-world issues per day of testing. Pure black-box is available if that better matches your threat model.

Do you need our source code?

No — this is a black/grey-box dynamic test against the running application. If you also want the codebase reviewed, see Source Code Review.

Staging or production?

Either — a production-like staging environment is ideal so we can test destructive edge cases freely; testing production directly is common too, within an agreed rules-of-engagement window.

How long does it take?

Most single-application tests take one to two weeks depending on the number of user roles and workflows, confirmed during scoping.
