At Axus Advisory Group, I protect IT/OT environments for mining sector clients through threat detection, triage, and incident response. I work with Cisco Secure Endpoint and CrowdStrike Falcon, mapping activity to MITRE ATT&CK.
I implemented IPsec tunnels and microsegmentation for vendor access, and used IBM QRadar to implement over 15 use cases and five correlation rules. Continuous tuning reduced false positives by 70%.
I also managed phishing containment for an oil and gas client, completed Claroty CTD upgrades without affecting OT operations, and identified vulnerabilities using Nessus. Before Axus Advisory Group, I supported IT operations at Caja Metropolitana de Lima, including Active Directory administration and Windows and Linux hardening.
