Cole Bermudez | Systems Administrator

About

Security-focused Systems Administrator with experience supporting enterprise infrastructure across systems administration, vulnerability management, logging, and compliance-driven operations. I have hands-on experience with tools including Nessus, Rapid7, Wireshark, and Splunk to identify vulnerabilities, investigate anomalies, and support remediation efforts across production environments.

My background includes designing secure file transfer workflows for sensitive data, maintaining endpoint protection and vulnerability response processes, and improving operational visibility through centralized logging and documentation. I have contributed to environments aligned with NIST, CIS, SOC 2, and ISO 27001 frameworks, with a strong emphasis on practical, implementable security.

With experience spanning Linux administration, networking, virtualization, scripting, and cloud platforms such as AWS and Microsoft Azure, I approach infrastructure from both an operational and security perspective.
