Adnan Kakkattil | Cybersecurity, Ethical Hacking & AI Security

I’m Adnan Kakkattil, a Cybersecurity and AI Security professional, technology entrepreneur, and cybersecurity instructor passionate about making technical education practical, accessible, and career-focused.

My expertise spans Cybersecurity, Ethical Hacking, Penetration Testing, AI Security, Web Application Security, API Security, Cloud Security, Secure Software Development, and AI Engineering. I focus on understanding how systems can be attacked, identifying security vulnerabilities, and building more secure applications and infrastructure.

I currently work as an AI Security Analyst, focusing on security challenges in modern AI applications and enterprise environments. As the Founder of ZyrOps, I also work on building innovative technology and software solutions. Through the Zero Cost Skill community, I support the mission of making high-quality technical education more accessible to aspiring learners.

My Approach to Cybersecurity Education

I believe cybersecurity is best learned by doing, experimenting, and understanding how things work under the hood.

My courses emphasize practical, hands-on learning through isolated labs, guided exercises, security testing tools, realistic attack scenarios, vulnerability assessment, penetration testing methodologies, and defensive security techniques.

Rather than simply teaching which commands to run, I aim to explain:

- What a security technique does and how it works.

- Why a vulnerability exists and what makes it exploitable.

- When to use a particular tool or testing methodology.

- How to validate findings, understand their impact, and recommend effective mitigations.

- How to practise safely in controlled lab environments.

What You Can Learn From My Courses

My teaching interests include:

- Ethical Hacking and Practical Penetration Testing

Who Should Learn With Me?

My courses are designed for aspiring ethical hackers, cybersecurity students, IT professionals, developers, penetration testers, and technology enthusiasts who want to develop practical security skills.

Whether you're starting your cybersecurity journey or expanding your existing technical knowledge, my goal is to help you build a strong foundation, think critically, practise responsibly, and develop skills you can apply in real-world environments.

My philosophy is simple: Learn by doing. Understand the why. Build the skills to secure what matters.
