About David O.

I operate at the intersection of technical support and security operations, with 5+ years of experience in environments where speed, accuracy, and risk awareness matter.My background includes hands-on experience at Darktrace and Skybox Security, where I worked in high-volume environments handling 70–90 daily incidents, troubleshooting access issues, identifying anomalies, and maintaining precise documentation aligned with security workflows.I bring a security-first mindset to everything I do, from endpoint hardening and access control to recognizing patterns that may indicate potential threats. My experience has built a strong foundation in incident triage, log awareness, and escalation procedures used in SOC environments.Core strengths:• Alert triage and incident documentation• SIEM exposure (Splunk, Microsoft Sentinel – foundational)• Identity & Access Management (Active Directory, least privilege)• Network and endpoint awareness• Security frameworks (NIST CSF, Zero Trust, CIA Triad)I am actively deepening my hands-on SOC capabilities, with a focus on threat detection, log analysis, and real-world incident response.If you\'re building a team that values precision, consistency, and a security-first mindset, let’s connect.
