Download SecurityPlus for MDaemon


These are the minimum recommended system requirements for SecurityPlus for MDaemon to run. This does not take into account running multiple programs simultaneously. To run several programs on the computer at the same time, that computer should exceed these recommendations.

  • MDaemon 11.0 or greater
    (MDaemon 14.0 or higher is recommended)
  • The number of SecurityPlus user licenses must equal (or be greater than) the number of user accounts in your MDaemon server, otherwise, you will not be able to add new MDaemon accounts, or SecurityPlus will be deactivated until you increase your SecurityPlus license size.
