Web Application Penetration Testing
Could someone access or change something they shouldn't in your web application?
Your web application is the part of your business that customers actually touch. It handles their accounts, their data and often their money. A web application penetration test approaches it the way a real attacker would: find a way in, see how far it goes, and document every step.
We test within an agreed scope, verify every finding by hand, and report in two layers: technical detail for your developers, and business impact for the people who make decisions.
What we test
Authentication: login, password reset, account recovery and how sessions are established
Authorization: whether a user can reach data or functions meant for someone else, including admin areas
Input handling: injection flaws such as SQL, command and template injection
Business logic: whether workflows like pricing, discounts, orders and approvals can be manipulated
Session management: cookies, tokens, logout behaviour and session fixation
Configuration: security headers, error handling and unintended information leakage
How we test it
We agree the scope first: what to test, when, and what is off limits.
Testing combines manual work with automated tools and AI assisted analysis.
Every finding is verified by hand, with evidence captured for your team.
The weaknesses that matter
These are the kinds of findings this assessment is built to catch, each explained the way it would appear in your report.
OWASP A01:2021
Broken access control
A customer changes an identifier in a request and sees another customer's data: the most common serious weakness in web applications today.
OWASP A03:2021
Injection
A search box or form field accepts commands the application was never meant to run, turning a simple input into a serious breach.
OWASP A07:2021
Broken authentication and session handling
Sessions that survive logout, or credential checks that can be bypassed, let an attacker sit inside a legitimate account, often for weeks, without the user or the business knowing.
OWASP A04:2021
Business logic flaws
A discount code is applied twice, a price is changed after payment, or an order skips a step the business never intended to allow.
OWASP A05:2021
Security misconfiguration
Default settings, verbose error pages and missing security headers give an attacker an easier route in, and tell them exactly where to look next.
OWASP A10:2021
Server-side request forgery
The application fetches a URL supplied by a user, letting an attacker reach internal systems that were never meant to face the internet.
