Frequently Asked
Questions agencies ask.
What does "perpetual licence" mean?
You pay once and own the right to use IMCS indefinitely on your infrastructure. Annual support is optional, not required.
Can we upgrade our plan later?
Yes. Moving from Plan A to Plan B or Enterprise requires only a licence upgrade — no reinstallation needed.
Is the source code available?
The source code is available for security audit under NDA. We support on-site compilation for agencies that require it.
What does on-site installation include?
Our engineers install and configure IMCS on your infrastructure, run the key ceremony, train your system admins, and sign off the deployment with a verification checklist.
Do you offer a trial?
We offer a 90-day pilot deployment on a single server. Contact us to discuss pilot requirements.
