Justin Elze

CTO, Director of Research

EXPERIENCE
Justin Elze is currently serving as Chief Technology Officer at TrustedSec. Over his 8 years with the company as an InfoSec expert, Justin has used his vast expertise in enterprise penetration testing, network security, social engineering, and red teaming to identify clients’ vulnerabilities and ultimately, protect their technology infrastructure. Prior to becoming CTO, Justin held the roles of Director of Innovation, Research, and Advanced Testing and Principal Security Consultant for TrustedSec.

With more than a decade of experience in the IT industry, Justin’s expertise is increasingly sought out by others in the field. He has taught at Black Hat and spoken at DerbyCon, where he also served on the CFP Review Board, and is also featured as an industry leader in the published books Tribe of Hackers: Cybersecurity Advice from the Best Hackers in the World and Tribe of Hackers Red Team: Tribal Knowledge from the Best in Offensive Cybersecurity.

Prior to joining TrustedSec, Justin was a Senior Penetration Tester for Accuvant LABS, Optiv, Dell SecureWorks, and Redspin, where he led numerous red team engagements and penetration tests. He has worked across a variety of industries, including roles for ISPs, hosting companies, Department of Defense contracting companies, and consulting companies. Today, he leans on what he learned throughout his roles in various capacities to inform his choices as CTO and further his thought leadership in the industry.

Outside of his work experience and “ethical hacker” persona, Justin is passionate about building, tuning, and racing cars (and, yes, occasionally hacking them) and spending time with his 3 dogs. You can find his latest musings—security-related and otherwise—on his Twitter account, @HackingLZ.
