[ 01 ]Vulnerabilities
Example web application vulnerabilities
The goal of running a web application pentest is to expose vulnerabilities before cybercriminals do. Click through examples of common vulnerabilities uncovered during web application pentests. We describe the risk level and impact, just as we do in our independent pentest report.
Possibility of SQL injection
Through insufficiently validated input fields, an attacker can execute their own SQL commands against your database, resulting in access to, modification of, or deletion of sensitive data. We test every form and every parameter for this.

[ 03 ]Our process
How does a website pentest work?
No jargon, just a clear process. Click a step or sit back and relax.
Introduction & Scope
A no-obligation conversation or an interactive questionnaire, in which we determine the scope of your website or web application together.
[ 04 ]Pentest methods
Pentesting methods
Black, Grey or White box? Pick a method below and see instantly how much knowledge the ethical hacker gets up front, and therefore how realistic the attack is.
The hacker starts completely blind
Black box Pentest
In a black box penetration testthe organization gives the ethical hacker no information about the systems and IT structure up front. The ethical hacker only receives a scope consisting of a URL and/or IP addresses. This mimics how a "real hacker" operates: a malicious actor obviously has no internal knowledge either and has to gather everything themselves.
What the hacker sees up front

โI've capped off 5+ years of experience as an ethical hacker with an OSCP, OSED, OSWE, OSEP & OSCE3 certification. With that knowledge, I make sure your networks, websites, and mobile applications are tested thoroughly.โ





Frequently asked website pentest questions
How do I secure my website against hackers?
There are various measures you can take to secure your website against hackers. For example, you can regularly install updates, use strong passwords and install an SSL certificate. It's also important to regularly run a web application pentest to detect and fix any vulnerabilities.
What are the most common vulnerabilities in a web application?
Examples of common vulnerabilities in web applications include SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and improper authorization checks. It's important to detect and fix these vulnerabilities to secure your web application.
How can I protect my website against DDoS attacks?
To protect your website against DDoS attacks, you can, for example, use a DDoS protection service or a firewall. You can also host your website with a provider that offers DDoS protection. It's important to regularly test whether your website is resilient against DDoS attacks.
What is a firewall and do I need one?
A firewall is a security measure that can filter and block incoming and outgoing network traffic. Whether you need a firewall depends on various factors, such as the size and complexity of your network, and the risk of attacks. In general it's advisable to use a firewall as an extra layer of security.
What are the best security measures for building a website?
Some best practices for building a secure website are regularly updating software, using strong passwords, implementing an SSL certificate, running web application pentests, applying access control and limiting functionality to what's strictly necessary.
How often should I have a website pentest carried out?
It's recommended to run a website pentest annually or after major updates, to detect and fix any new vulnerabilities.
How long does a website pentest take?
The duration of a pentest depends on various factors, such as the type of test, the complexity of the system and the available budget. A pentest usually takes a few days to a few weeks, but it can also take months. The duration of the pentest is always discussed with the client beforehand.
It's important to emphasize that the time an ethical hacker spends carrying out the pentest affects the thoroughness of the test and the methods applied. The more time the pentester gets, the better the test can be carried out.
Whether you need a one-day pentest or a more extensive pentest of several weeks or months, at Tozetta we always determine the duration of the test in consultation with the client. This way we can ensure the test aligns as closely as possible with your organization's wishes and needs.
