Mario HS

I am a results-driven Security Operations Center (SOC) Analyst with over seven years of experience in cybersecurity, threat detection, incident response, and IT operations. I have extensive hands-on experience with SIEM platforms (QRadar, RSA, FortiSIEM, Splunk) and SOAR solutions such as Sentinel to provide continuous monitoring and rapid incident handling.

Throughout my career I have improved operational outcomes by reducing incident response times by 18%, increasing detection accuracy by 12%, and maintaining patch compliance rates above 95%. I have performed malware and malicious URL analysis, log and network traffic analysis, and supported vulnerability management using tools like Qualys while aligning work with NIST 800-53, FISMA, and ISO 27001 frameworks.

I collaborate effectively across multidisciplinary teams, leverage ticketing platforms (ServiceNow, Jira, The Hive), and communicate technical findings clearly in English and Spanish. I am pursuing a Master’s in Cybersecurity to deepen my expertise and continue driving security improvements in large-scale environments.
