Summary
👤
Senior🎓
Top SchoolGabriel Cornyn is a Senior Penetration Tester with 10 years of experience blending offensive and defensive network and application security, CI/CD automation, and infrastructure engineering. He has led and scaled consulting teams through mergers and acquisitions while owning the internal infrastructure that supports 14+ consultants, maintaining Kali builds, Jenkins pipelines, and multi-cloud/ESXi deployments. Gabriel pairs hands-on pentesting and exploit analysis with practical DevOps: he develops shell and Python tooling, administers pfSense VPNs, and delivers customer-facing artifacts via AWS S3. His background includes building hardened remote access and build systems at Rapid7 and creating IPS detection logic earlier in his career, giving him deep visibility into both attack techniques and detection design. Based in Denver, he’s equally comfortable mentoring teams and troubleshooting complex customer network environments, and he often automates repeatable tasks to turn ad hoc testing into reliable operational workflows.
