Hans Study

Hans Study is an independent network and security expert based in Ontario, Canada. Fifteen years across the public sector, defence, public safety, and critical infrastructure, designing networks and physical security systems for organizations where reliability and operational security are not optional.

The work is boutique. Enterprise networks, OT and ICS, controls and security systems, and the infrastructure underneath them. Hans specializes in hardening and tuning systems where the stakes are high and the margin for error is small. Primary stacks: Microsoft Windows, Cisco, Aruba, and Genetec Security Center, with regular work across Axis, Bosch, Milestone, Avigilon, C-CURE, Fortinet, Palo Alto, Juniper, and Alcatel-Lucent OmniSwitch.

Hans is the author of The Study Guide series, a practitioner-focused book series including "The Study Guide to CCTV and Access Control Systems" and "The Study Guide to Network and System Hardening: A Field Guide for Systems and Security Integrators." He hosts the StudyByt3s podcast and develops technical courseware for practitioners and integrators.

What clients get: independent advice, not vendor pitches. End-to-end engagements from site assessment through commissioning. Compliance support for CMMC, CPCSC, ISO 27001, and NIST 800-171. Honest assessment of what works and what does not.

CISSP is the one credential Hans keeps current. Others have come and gone, kept when useful, dropped when they were not. Serves clients across Canada and the United States in government, public safety, defence, critical infrastructure, healthcare, and enterprise environments.
