Web Security Fundamentals
For Developers

Developers with Security Skills in High Demand, Are You Prepared?

Become a Security-Oriented Web Developer and Watch Your Salary Soar Like Crazy!


This training is for developers who want to understand the WHAT, WHY, and HOW, instead of copy-pasting the code from StackOverflow.

The skill of understanding "the reasoning behind" is the superpower of top developers in the world that are in the highest demand! 🦾

In this course, you will...

✔️ Learn about the most important Web security principle that dictates how browsers run the websites (this policy rules them all!),

✔️ Understand the reasoning behind CORS errors (yes, yes - this infamous No Access Control Allow Origin headers is present error!),

✔️ Build a standard cross-site scripting attacks prevention shield 🛡 (XSS can steal cookies, impersonate users and make a lot of harm),

✔️ Set up reporting features to catch attack attempts (notifications on the security violations),

✔️ Create integrity checks on external scripts (again, to eliminate the risk of deadly XSS attacks!),

✔️ Learn how JSON Web Tokens (JWT) can be hacked (this will blow your mind) 🤯

✔️ Understand how time-based one-time passwords (TOTP) work for 2-factor authentication 🔑

✔️ Receive a comprehensive summary of OWASP Top 10 security vulnerabilities 📝

✔️ Access the exclusive Discord community of security-oriented Web developers 👩‍💻

✔️ Receive a certificate of completion with your name on it 📜


✔️ 7 must-know steps to making modern web applications secure as medieval strongholds! ⚔️ (step-by-step guide, that you won't find on Udemy)

Practical coding laboratories in JavaScript

You will see the concepts applied in practice in dedicated laser-focused coding labs and play with them on your own

In-depth theory explanations

You will learn about all the WHATS and WHYS behind the presented concepts to have a crystal-clear understanding

Do not let AI Take Your Job as a Developer in 2024!

Become a Security-Oriented Developer 🥷

The rise of Artificial Intelligence in the tech industry has caused concern among developers, who worry that they may be replaced by robots.

However, the reality is that there is still a high demand for developers who have specialized skills, especially in the field of web application security.

In a world where cyber attacks are becoming more and more frequent, companies are in desperate need of developers who have the skills to protect their online assets.

By specializing in Web security, developers can differentiate themselves from the average developer and provide valuable expertise to companies.

This not only guarantees job security but also increases their salary as they become in high demand.

As AI continues to advance, it is essential that developers take proactive measures to improve their skills and stay ahead of the curve.

The Web Security Masterclass is the perfect opportunity for developers to do just that and secure their future in the tech industry.

This course is designed to be a comprehensive, step-by-step process with coding laboratories that allow you to gain hands-on experience. 👩‍💻

The level of detail in the explanation videos and practical coding labs is highly praised ♥️ by students, making it way more effective than watching free YouTube videos. 🎬
