  • The Check_MK Managed Services Edition (CME) - for managed services providers as the name already implies
  • The virtual appliance for the use within an existing virtualization platform

If you want to try out the Enterprise (CEE) or Managed Services (CME) edition, you can download the demo versions listed below. Keep in mind though, the demo versions don't have any limitations, but instead throw random errors.
