    Define global filter rules

    Manage user, group, and space rights

    Prevent illicit file uploads

    You can configure a global whitelist of file extensions that you want to allow for file uploads. Only file types specified in that list will be accepted for file attachments.

    The add-on's flexible configuration options enable you to specify refined permission schemes for users, groups, and spaces, giving you more control over the data accepted and provided by your Confluence instance.

    Restrictions in the types of files that may be uploaded are effectively enforced by the add-on in any place the user can attach a file to a page. Descriptive error messages inform about acceptable file types.

    Paid-via-Atlassian pricing FAQ

    How does server add-on pricing work?

    Server products and add-ons are hosted on your servers. Licenses are perpetual and the purchase price include 12 months of maintenance (support and version updates).

    You can renew maintenance after 12 months at 50% of the current purchase price. You can upgrade the tier of your host product and add-on licenses at any time. Upgrade prices are calculated based on Atlassian's formula (view example).

    If add-on pricing changes after your initial purchase, there's a 60-day grandfathering period during which you can renew based on the old pricing.

    How do I determine my server pricing?

    Add-ons are billed based on the number of users in your host product. The add-on tier should match the licensed user tier of the Atlassian host product. For example, if you have a Confluence Server license for 25 users, you should purchase the 25-user tier for add-ons. Even if fewer users want to use the add-on than your host product license, the two licenses should match exactly.

    Do you offer academic, community, or open-source licenses?

    For server add-ons, purchase and renewal is half-price if you have an academic license for your Atlassian host product. Server add-ons are always free for community and open-source licenses.

    For more details about qualifying for special licenses, see here.

    Can I extend my free trial?

    For server add-ons, you can extend your add-on trial up to 5 times - in other words, for up to six months. Extend your trial by generating a new evaluation license key from Atlassian Marketplace. Click Try it free and you'll be directed to generate a new license. Paste this license key into the add-on listing in UPM from your Atlassian host product, and you're all set.

    How can I buy add-ons for my legacy JIRA Server or Confluence Server license?

    If you own a legacy JIRA Server Unlimited (100+ users) or Confluence Server Unlimited (2000+ users) license purchased in 2012 or earlier, legacy add-on pricing is no longer available. You have two options for add-on purchasing:

    • Purchase the add-on at the non-legacy Unlimited (10000+ users) tier.
    • Renew your JIRA or Confluence license at a non-legacy tier, then purchase the add-on at the same tier.
