In Jira, we use regular Web Links to point to an independent issue tracking system (for customer support). Those links can easily be identified by their domain name or URL prefix, e.g., they all have this form:

ScriptRunner for JIRA offers the Script JQL function "linkedIssuesOfRemote" that searches for issues that have a link to a specific web page, e.g.:
will return all issues that link to that page. Instead of the link you might use the link title too.
