See Your Website Through an Attacker's Eyes
Learning how to pentest a website is like seeing your digital property through an attacker's eyes.
Have you ever wondered what a burglar sees when they look at a house? They see opportunities and weak points, not just doors and windows.
A cybersecurity professional does the same for your website. They look for the digital cracks that criminals could exploit.
A website penetration test is a planned, simulated attack. It's designed to find weaknesses in a safe way. This lets you fix them before someone with malicious intentions finds them.

How to Pentest a Website: The Core Phases
A professional cybersecurity audit follows a clear process. Each step builds on the last. The process moves from gathering general information to running specific, targeted tests.
Step 1: Scoping and Getting Permission
This is the most important step. Without a signed contract, you’re not performing a pentest. You’re committing a crime.
This contract is often referred to as the "Rules of Engagement". It outlines what to test and what to avoid. It also sets the timeline and provides emergency contacts.
This document is the legal foundation for the test.
Step 2: Reconnaissance (Information Gathering)
This is the intelligence-gathering phase. The goal is to learn as much as possible about the website using public information. We look at all the technologies you use, like the content management system or web server software.
We do this because older software versions often have known security flaws. These flaws give us a starting point for an attack.
Step 3: Scanning and Enumeration
In this phase, our pentest experts start to interact with the website. We map out all the ways it could be attacked and use specialised tools to find open ports, running services, and hidden pages.
The goal is to build a complete picture of the website's structure and find all the possible entry points.
Step 4: The Attack Phase (Exploitation)
This is where the simulated attack happens. We use the information we’ve gathered to try and exploit any weak spots. This involves testing for common flaws.
We use industry-standard resources like the OWASP Top 10, a world-renowned list of the most critical security risks.
For example, we could try an SQL Injection. This attack uses a site's search bar or another input field, then we insert malicious code to trick your database into giving up confidential information.
Importantly: All of this is done safely, without causing real damage.
Step 5: Post-Exploitation
Getting inside is often just the start. Once in, we try to find out how much damage an attacker could actually do.
- Can they access private customer data?
- Can they take over the whole system?
This phase shows the real business risk of a security flaw. It turns a theoretical problem into a real threat.
Step 6: Reporting and Remediation
The final report is the most valuable part of the website penetration test project.
This professional report isn’t just a list of problems; it includes a short summary for managers and detailed technical notes for developers. It also rates how serious each flaw is and gives clear, actionable steps on how to resolve the issues.
This structured process forms the foundation of every professional pentest, but the real value comes from the expertise applied at each stage.
The Difference Between Theory and Expertise
These six steps provide a good framework. But simply following a checklist is not enough.
A real website penetration test is an art. It needs deep technical knowledge, creativity, and years of experience.
A DIY approach to pentesting your website is risky. You could easily miss critical flaws that automated tools cannot find. This leaves you with a false sense of security, which is dangerous. Worse, you could accidentally damage your systems. This can lead to downtime and lost data.
Outsourcing to a team of dedicated cybersecurity professionals is the best way to get a true picture of your security.
At 7ASecurity, our founder, Abraham Aranguren, created the OWASP Offensive Web Testing Framework (OWTF), an OWASP Flagship project. This shows our genuine commitment to the security community and our expertise in the field.
Our team knows exactly how to pentest a website. We work far beyond a simple checklist to find the critical issues that others miss.
A Defence That Won't Let You Down
Understanding how to pentest a website shows you the value of the process. But doing it right is a professional skill. An incomplete test will let you down, especially when an attacker finds what you missed. A professional one, backed by years of expertise, won't.
