As a Cybersecurity Network Analyst, I monitored and analyzed over 12,000 daily security events using Splunk, efficiently identifying and mitigating potential network security breaches. I actively participated in over 100 incident response operations, reducing average threat resolution time by 35% through effective investigation, containment, and mitigation strategies. By analyzing network traffic across systems with more than 5,000 active users, I proactively identified vulnerabilities, preventing potential cyberattacks. Additionally, I developed and deployed Python scripts to automate threat detection tasks, which reduced manual workloads by 25% and significantly improved response times to critical security events. Collaborating with cross-functional teams, I ensured compliance with industry standards such as NIST and ISO 27001, improving internal audit success rates from approximately 50% to 80% and enhancing the organization's cybersecurity posture. Furthermore, I worked closely with the software engineering team to integrate advanced security measures, safeguarding personally identifiable information (PII) and sensitive personal identifiable information (SPII) for medical patients, ensuring access was restricted to authorized users only.
