Talk to the person who built it.
One address. It goes to the person who built it, not a queue.
Curious about Cairn for your practice, or reviewing it for your dealer's security, data, or vendor process: same address. Say which firm you're with and what you need. Questionnaires, architecture questions, and the known-gaps sheet are all answered directly, usually by the next business day.
Cairn Systems is based in Kelowna, British Columbia.
