Our Areas of Expertise


We determine your attack surface and provide actionable items to bolster your security by performing a pentest on your facility.


Move critical systems that are being neglected to a secure and monitored cloud environment.


Regular maintenance by an expert in building automation and cybersecurity reduces the magnitude and possibility of an incident.


The protocol used to make your equipment interoperable does not include any encryption and requires an insecure port for remote access. BACnet Secure Connect (B/SC) can fix this, and we can help.

David Brunsdon

Founder, Certified Ethical Hacker, Comptia Advanced Security Practitioner

I created Dark Ivy Consulting to help ensure the availability of the systems that keep us healthy, efficient and safe. My background in control systems and passion for ethical hacking give me a unique perspective on how to secure the built environment. As a travelling instructor of building automation, I’ve presented to people all over the world.

No matter what challenges their unique environment faced, the mission was always the same: I help people lower their operational expenses, mitigate loss, and ensure continuous operation of their critical systems.
