About Christopher Bristol

With over three years of experience in the cybersecurity domain, my mission has been to fortify defenses and preempt cyber threats. At Dell Technologies, my core competencies in information security and endpoint security were integral to protecting critical infrastructure. My dedication to cyber threat intelligence (CTI) and the values I share with Dell have driven me to detect and neutralize over 200 security incidents, contributing to a resilient and secure digital environment.During my tenure at Dell, I honed my skills in forensic analysis and incident response, significantly reducing response times by 25%. My collaboration with cross-functional teams enhanced threat detection capabilities and security policies. This experience, coupled with my proficiency in leveraging SIEM tools and conducting forensic artifact analysis across various environments, underscores my commitment to maintaining robust cybersecurity measures.
