About

With over 12 years of experience in IT, I am a passionate cybersecurity professional with a BS in Cybersecurity and Information Assurance. I have a strong background in technical support, operations, and Linux systems administration/engineering, and I hold multiple CompTIA certifications, including Project+, Network+, Security+, Pentest+, and CySA+. I currently work as an Information Security Analyst on the Governance, Risk, and Compliance team at Tenable, where I use my product and cybersecurity knowledge to respond to customer security questionnaires, conduct third-party risk assessments, and work with third-party auditors to maintain the various certifications my company holds.
