I’m Jeff McJunkin, founder and principal consultant of Rogue Valley Information Security — a consultancy focused on penetration testing and red team engagements for organizations ranging from regional businesses to Fortune 100 enterprises.

I’m also a Principal Instructor with the SANS Institute, where I co-authored and teach SEC560: Enterprise Penetration Testing and SEC580: Metasploit for Enterprise Penetration Testing. I bring decades of systems, network, and offensive security experience, and much of my teaching comes straight from real-world assessments — how actual attackers move through enterprise environments, and how defenders can detect and stop them.

Outside of consulting and the classroom, I’ve built Core NetWars challenges, contributed to the SANS Holiday Hack Challenge, and spoken at conferences including RSA Conference, Wild West Hackin’ Fest, and events with Black Hills Information Security.
