Background

About Jonathan Arnold

I’m a cybersecurity leader with 15+ years of experience driving enterprise security, infrastructure management, and technical team growth. My career has spanned from hands-on systems administration to leading enterprise-scale security initiatives for organizations in highly regulated industries. Along the way, I’ve built a track record of strengthening security postures, leading migrations, and mentoring high-performing teams. Highlights include directing the FDA’s Zscaler migration to ZIA/ZPA with full rule configuration and team training, architecting Toyota’s enterprise Varonis migration to O365/Azure AD with governance frameworks adopted by senior leadership, and advancing from analyst to team lead at Allscripts where I mentored staff and resolved enterprise-critical incidents. I thrive at the intersection of technical depth and leadership, aligning cybersecurity strategies with organizational goals while fostering collaboration across engineers, stakeholders, and executives. Currently pursuing CISSP certification, I’m focused on advancing into Director- and VP-level roles where I can continue building secure, scalable infrastructures and guiding teams to success.
