Portfolio

Welcome to my Technical and Strategic Cybersecurity Portfolio

I am Juan Sebastián Berón Ramírez, a professional passionate about cybersecurity and looking to strengthen my knowledge in the field. This site combines applied technical knowledge, a commercial track record, and a passion for building secure and efficient digital environments.

The idea of this site is to compile the best and largest amount of information related to cybersecurity, so you can find it all in one place, saving you the hassle of searching.

Here you’ll find a selection of real projects developed in my home lab, with step-by-step guides on ethical hacking, SIEM implementation, vulnerability analysis, secure environment configuration, and much more.

This portfolio is designed for three key purposes:

• Learn as much as I can in this field
• Showcasing my technical and strategic competencies in cybersecurity
• Serving as an educational reference for developing professionals

I invite you to explore, learn, and connect.
I’m open to collaborations, technical challenges, and high-impact opportunities in the digital world.
