Austin, TX • socanalyst@gmail.com • +1 512-555-0142
Profile Summary
- Senior SOC Analyst with 7 years of experience working 24/7 enterprise and MSSP security operations centers across SaaS, internet infrastructure, and managed-security clients, specializing in SIEM investigation, endpoint response, and phishing analysis.
- Hands-on coverage across SIEM (Splunk Enterprise Security, Microsoft Sentinel), EDR (CrowdStrike Falcon, SentinelOne), phishing defense (Proofpoint), automation (Splunk SOAR), intel platforms (MISP), and scripting (Python, PowerShell), plus a solid grounding in clean shift handovers, ATT&CK technique mapping, and incident notes that hold up in a postmortem.
- Deep expertise in ATT&CK-mapped detection coverage, log correlation across SIEM and EDR, disciplined alert triage, and intel-led threat hunting, working through the NIST SP 800-61 incident lifecycle and monthly purple-team exercises to deliver faster containment and incident reports that leadership can act on.
- Engaged collaborator working closely with IT, Legal, and the detection engineering team in 24/7, follow-the-sun environments, showing up on incident bridges, in tabletop exercises and at post-incident reviews, from the first alert to the final report.
- Emerging leader who lifts the team’s standard for alert hygiene and handover-note quality through weekly case reviews, while running a detection study group for tier 1 and writing the triage and incident templates new analysts start from.

Education
Work Experience
- Work the 24/7 alert queue for Cloudflare's global edge and corporate network (3,200+ employees), triaging 350+ Splunk and Sentinel alerts a week and meeting the 15-minute escalation SLA on 98% of confirmed threats.
- Investigated 220+ confirmed incidents across laptops, Okta, AWS workloads, and edge logs, correlating firewall, DNS, proxy, and CloudTrail logs in SPL and KQL to rebuild attacker timelines, cutting the average time to scope an incident from 3.5 hours to 70 minutes.
- Ran endpoint investigations on CrowdStrike Falcon across 4,500+ laptops and servers, using process-tree analysis, Real Time Response sessions, and fleet-wide IOC sweeps with one-click host isolation, which cut the average dwell time on an infected host from 11 hours to 34 minutes.
- Handled 40+ SEV1 and SEV2 incidents through the NIST SP 800-61 lifecycle, running containment on the incident bridge (host isolation, Okta session revokes, edge blocks) and writing each post-incident review, which cut repeat incidents from the same root cause by 61%.
- Tuned and wrote 120+ detection rules in Sigma and KQL, each mapped to a MITRE ATT&CK technique and tested with Atomic Red Team before release, cutting false positives from 68% of the queue to 21%.
- Led 30+ hypothesis-driven threat hunts based on MISP and FS-ISAC reporting about actors targeting internet infrastructure, and added automatic IOC enrichment to every alert, finding 9 compromises that no existing alert had caught.
- Worked the reported-phishing queue on Proofpoint for 8,000+ user reports a year, using header analysis, URL detonation, and sandbox runs on attachments, cutting the time to purge a campaign from every inbox from 2 hours to 11 minutes.
- Built 14 Splunk SOAR playbooks for alert enrichment, phishing triage, and account lockouts, plus the Python scripts and runbooks behind them, saving the team about 25 analyst hours a week.
- Monitored 12 client environments on the 24/7 MSSP queue in IBM QRadar and Splunk, escalating 300+ confirmed incidents a year to client IT with fewer than 3% sent to the wrong team.
- Wrote 45 incident playbooks and triage runbooks that became the SOC standard for every client, reviewed each quarter with the SOC lead, cutting escalations returned for missing data by 40%.
- Coordinated containment windows and phishing takedowns with client IT, threat intel, and legal teams, tuned 70+ QRadar rules into the team’s triage baseline, and onboarded 5 new analysts to the night shift.
