About Web App Pentest

Your Partner in Web Application Security

Web application penetration testing is a hands on security assessment where our testers act like real attackers to find weaknesses in your login flows, APIs, forms, and back end logic. Automated scanners catch the obvious issues, but most serious vulnerabilities, like a checkout flow that lets someone change a price, or a user role that can be escalated, only show up under manual testing.

Most businesses run their applications publicly on the internet, which means anyone can probe them at any time. A single penetration test before a launch, a major release, or a compliance audit gives you a clear picture of what an attacker could actually do, not just a list of theoretical risks. Regular testing also keeps pace with new features, since every code change can introduce a new flaw.

Frequently asked questions

Answers to the questions we hear most. Still unsure how it applies to your environment? Our engineers are happy to talk it through.

What does a web application penetration test actually cover? 
It covers authentication, access control, input handling, session management, business logic, and server configuration, essentially every way a user or attacker can interact with your application.
How is this different from a vulnerability scan?
A scanner flags known patterns automatically. Our testers manually exploit findings to confirm they're real and assess what an attacker could actually achieve, including logic flaws no scanner can detect.
Do you need access to our source code?
No, but it helps. We can test without it (black box) or with it (white box), depending on the depth you need and your timeline.
Will testing affect our live application?
We schedule testing windows with your team and use controlled methods to avoid disrupting uptime or live customer data.
How long does a web app pentest take?
Most engagements run one to three weeks depending on the size and complexity of the application.
Do you retest after we fix the issues?
Yes, retesting is included, so you have documented proof that vulnerabilities are closed.
