Hey everyone, I’m Camron. I’m a veteran with about 8 years of experience across IT and security, and I currently work as an IT Specialist while transitioning more fully into cybersecurity. My background includes security operations, access management, system hardening, and incident response support in enterprise environments. I’m finishing a Master’s in Cybersecurity Technology along with a Digital Forensics and Cyber Investigation certificate at UMGC. I currently hold Security+, CCNA, Splunk Core User, and AZ-900 certifications. Right now, I’m focused on growing from analyst-style work into more engineering-focused roles, with a long-term interest in IAM and identity security. I joined this group to learn, share experiences, and connect with others building meaningful careers in tech.

If you see these before I get to them, please report it Thank you!
