Senior🎓
Top SchoolDavid Teo is a Network Security Engineer with 12 years of hands-on experience defending enterprise environments, currently protecting customers at LevelBlue (formerly AT&T Cybersecurity) against DDoS and intrusion threats. He specializes in Splunk SIEM—designing and tuning ES use cases, normalizing log sources to CIM, and leading incident investigations and threat hunting. Comfortable bridging technical and non-technical audiences, he serves as an escalation point during incidents and translates complex findings into actionable guidance for clients. His background includes offensive-style analysis of APT malware, building live Splunk visualizers and dashboards, and operational use of Arbor, Radware, Fortigate, Palo Alto and other defenses. Outside traditional security operations, he has tracked and built systems around blockchain technologies and managed cryptocurrency mining and investment experiments. Known for a “figure-it-out” mentality, he thrives in fast-paced, hands-on roles where pragmatic fixes matter as much as big-picture strategy.
