You can refer to this documentation to invite users to your JIRA instance (https://confluence.atlassian.com/display/JIRA/Managing+Users#ManagingUsers-inviteusers). You will of course have to manage your permissions in JIRA after that to only make sure that your external users can only see what they are allowed to see.
