Rosalio Mayo

I’m a cybersecurity professional with hands-on experience in offensive and defensive security. I completed the Cybersecurity Professional Program at the University of Colorado Boulder and hold a CompTIA Security+ certification. I’ve worked through 50+ labs and real-world projects involving network security, threat detection, penetration testing, and digital forensics.

I enjoy digging into traffic logs, hunting threats, breaking vulnerable systems (legally), and building stronger defenses. I'm fluent in English and Spanish and always open to new challenges in cybersecurity.

🚀 What I’m Focused On

• Threat detection, incident response, and SIEM tools like Splunk and Sentinel

• Penetration testing and red teaming with Kali, Burp Suite, and Python

• Blue team operations, including traffic analysis and host forensics

• Securing critical infrastructure systems in ICS/OT environments
