Chris Eheler

Systems, software, and security professional with six years of technical experience across application development, infrastructure, networking, and security operations. I build practical security tooling, detections, infrastructure controls, and automation grounded in real operational systems.

Selected security engineering work

Projects are documented as case studies rather than just repository links: architecture, implementation details, validation, example findings, and security tradeoffs.

Professional foundation

Security work backed by production engineering experience.

My background combines software development, systems administration, networking, virtualization, and hands-on security ownership rather than treating security as an isolated discipline.

Production security ownership

Wazuh SIEM deployment and administration across approximately 100 endpoints and machine controllers, FortiGate firewall administration, VLAN segmentation, site-to-site VPNs, event investigation, and PCI DSS remediation.

Engineering depth

Production C# development, Windows Server and Active Directory, Hyper-V, Cisco switching, SQL Server, Python, PowerShell, AWS, and Terraform.

Resume
