is it possible to only allow a user (or group of users) to view the issues that they created, while hiding the other issues in the project?

[Alex Mace]

we have a client who will enter issues, but, ultimately the issues will get moved into the Dev project. once their, I'd still like the client to be able to view the issue, but I don't want them to see all of the other issues in the project.

Yes, but with two important points - first you need to think about how to deny them access to everything you don't want them to see (this usually means re-engineering the default permissions, as the defaults basically say "if you can log in, you can see everything), and then specifically letting them see their own issues - for that, take a read of https://confluence.atlassian.com/display/JIRA/Current+Reporter+Browse+Project+Permission

Hi Alex,

As previously mentioned on this Answer you could use Issue Level Security to do so.

Specifically, you can set up a model to allow the reporter to view the issue similar to allowing only the Assignee on this guide: How to limit user to only browse issues assigned to them.

Then every issue in the Dev project will be visible to the reporter but hidden from everyone else outside the Development team.

Cheers! :)
