Dean Horn
@deanhorn
I am an information security engineer specializing in Check Point firewalls and high-availability infrastructure.
What I'm looking for
I am an experienced IT professional with nine years in the iGaming industry, focused on maintaining high-uptime infrastructure and securing large-scale environments. I deploy, manage and troubleshoot extensive Check Point firewall estates, create hundreds of IPSec site-to-site VPNs, and implement identity-based rules using OKTA to reduce blast radius for critical systems.
I prioritize automation, documentation and proactive monitoring—using Check Point Skyline, Zabbix and Grafana with PagerDuty to sustain 99.99% uptime—and I deliver infrastructure-as-code for repeatable deployments. I collaborate cross-functionally, conduct regular rulebase audits with Algosec, and continuously pursue certifications to strengthen security posture and operational resilience.
