Chris Horsley
Chief Technical Officer at Cosive
Melbourne, Victoria, Australia
Summary
👤
SeniorChris Horsley is a seasoned technology leader and co-founder serving as CTO of Cosive since 2015, with 15 years of experience building security-focused software and operations. He combines deep incident response and CSIRT expertise with hands-on engineering—automating IR workflows, large-scale data analysis, and operational data visualisation. His career includes roles at JPCERT/CC and AusCERT where he designed malware and phishing monitoring systems, ran international training, and developed tooling that turned noisy telemetry into actionable intelligence. Comfortable across Python, Perl and systems architecture, he has repeatedly bridged the gap between defensive security practice and pragmatic engineering. Based in Melbourne, he’s known for turning complex security processes into efficient, automated systems and for teaching teams to operate them under pressure. A detail that sets him apart: he pairs UI and data-visualisation experience (multi-touch kiosk projects) with deep backend automation to make security insights both accurate and usable.
