Edwin Madera Coronado

I am a cybersecurity analyst with over four years of experience building resilient security operations and advancing from threat triage to leading incident response and automation initiatives for global organizations.

At Abt Global I owned SIEM detection use case development and tuning in Wazuh and Devo, cutting false positives by 70% and improving high-fidelity alerting mapped to MITRE ATT&CK. I handled 40–70 incidents monthly and performed deep host analysis across Windows and Linux, increasing identification accuracy by 50%.

I managed the incident lifecycle using ServiceNow and Jira, partnering with stakeholders to reduce resolution times by 60%, and conducted vulnerability assessments with Tenable Nessus to prioritize remediation and lower risk exposure. I also enhanced cloud and SaaS security by implementing AWS and Azure log monitoring and improved perimeter security through FortiGate policy optimization.

I bring strong automation and operational experience—building Power Automate, Excel, and VBA workflows that drastically reduced processing time and ticket resolution—and a continuous focus on measurable outcomes, clear communication, and collaborative remediation.
