Reduce file exposure in Jira and Confluence Cloud by tightening access at each layer: anonymous access, project or space permissions, item restrictions, attachment-download controls, network access, and installed apps. No single setting prevents every way a person who can view a file might copy it, so apply the controls that fit your plan and workflows, then test the routes people and integrations actually use.

Start by mapping what should be exposed

Before changing access, identify which projects, spaces, pages, issues, and attachments are intended to be public, available to signed-in users, or restricted to a smaller group. Include public links and apps or API-connected tools that retrieve or display content.

  • Mark content intended for an unspecified audience as public; treat everything else as requiring authenticated access.
  • Identify confidential material and who needs access to it, including whether access should differ between a space or project and individual items.
  • List integrations and user workflows that rely on previews, notifications, APIs, or attachment downloads so you can test for disruption.

This inventory gives you a baseline for deciding whether a permission is necessary and for checking the results after a change.

Remove anonymous access that is not intentional

Check Confluence at each permission layer

Confluence exposure can depend on site-level access, space permissions, and restrictions on individual content. Atlassian says that when global access is enabled and a space grants anonymous access, the space is open to anyone on the internet except content restricted at the item level or through an inherited parent restriction. Anonymous content may also appear in Google search. Review the organization policy and any overrides, then check every space that permits anonymous access and the restrictions on sensitive pages. See Atlassian’s anonymous-access policy guidance and documentation on controlling whether spaces can enable public access.

Public access can be appropriate for material meant for a broad audience, such as public documentation, a roadmap, or support information. Keep that material in a purpose-built public space and grant only the access it needs; do not make an internal space public simply to share a few pages. Atlassian explains how to make a Confluence space public.

Review Jira separately

For Jira, check whether anonymous access is permitted by the organization or product policy and whether project permissions expose issues or their attachments. Do not assume that disabling anonymous access in one place changes every relevant project or policy override; verify the effective access for the projects in scope. Atlassian describes the policy-level control in its guidance on preventing anonymous access.

Narrow access for signed-in users

Requiring a login only excludes anonymous visitors; it does not make content private from every authenticated user. Apply least privilege at the smallest useful scope, and remove broad grants that are not needed.

In Jira

Review the permission schemes assigned to projects and the project or issue access controls relevant to your configuration. Confirm who can browse issues and whether those users need access to the attachments on them. Check access with representative accounts rather than relying only on the name of a group or role.

In Confluence

Review space permissions, then add page restrictions where a page needs a narrower audience than its space. Restrictions can depend on the page and its parent content, so check both when assessing access. Atlassian states that content restrictions are not available on the Confluence Free plan; confirm your plan before designing access around them. Its page-restriction guidance describes who can find content and what they can do with it.

Use attachment-download controls as one layer

Atlassian’s attachment-download control can block supported download buttons and API downloads. It is not complete copy prevention: a person who can view an attachment may still use browser-based saving or printing, browser tools or extensions, and an editor with permission may copy and paste an attachment onto another page. The control blocks a particular retrieval path, not every way to capture or reproduce content, so do not treat it as DRM or comprehensive data-loss prevention.

Before applying it, decide which users and content the policy should cover, and check whether the affected workflows rely on downloads. Then test both the supported download interface and API retrieval with appropriate accounts. Atlassian documents the control’s behavior and limits in Prevent attachment downloads.

Limit network access with an IP allowlist where eligible

An IP allowlist can limit access to supported Jira and Confluence content based on the source network. Atlassian says the Jira and Confluence allowlisting feature requires a Premium plan, and it is administered at the organization level. Confirm the tenant’s entitlement and policy configuration before relying on it. The official IP-address access documentation describes the supported configuration.

Allowlisting is not a universal barrier around every representation of content. Atlassian documents exceptions involving recent history, notification details, and Smart Links, as well as some application or API access. Rovo content can surface titles, previews, or paraphrases unless its relevant controls are configured. If your organization uses Atlassian MCP, requests are evaluated against the product’s IP allowlist while normal app permissions still apply; the tool’s source IP may also need to be allowlisted. Check the MCP documentation if that applies to your setup.

Before enforcing a network rule, identify the legitimate networks and user locations that must retain access. Test normal sign-in, previews, notifications, integrations, and API workflows from both allowed and disallowed networks. An allowlist can reduce access from unapproved sources, but it does not replace the content permissions that determine which users and apps are authorized.

Review apps and connected tools independently

Marketplace and custom apps may read user-generated content, including Confluence attachments. Do not assume that an app follows the same access boundary as a person using the product, or that a user-permission review or IP restriction covers every integration in the same way. Inventory installed apps and API-connected tools, confirm which content each can access, and check whether your policies cover that access. Atlassian’s Confluence app-access coverage summary describes the control’s coverage and exceptions; check the details against the apps you use.

Compare the controls by what they restrict

Control Primary boundary Important limit Availability noted by Atlassian
Anonymous-access policy and product permissions Access by people who are not signed in; Confluence also has site, space, and content layers. Broad space-level access can expose space content unless an item or inherited restriction applies. Review policy overrides and effective permissions. The cited anonymous-access policy requires Atlassian Guard Standard; classification coverage requires Guard Premium.
Project, space, and item permissions Which authenticated users can reach projects, spaces, or particular issues and pages. Login alone does not establish least privilege. Confluence content restrictions are unavailable on Free. Depends on the tenant plan and configuration; confirm the needed features before designing around them.
Attachment-download control Supported attachment download buttons and API downloads. Does not prevent viewing, browser-based saving or printing, browser extensions, or copying an attachment to another page by an editor. Requires Atlassian Guard Standard; classification-level coverage requires Guard Premium.
IP allowlist Access to supported Jira and Confluence content from source networks. Exceptions can include recent history, notification details, Smart Links, and some application or API access. Jira and Confluence allowlisting requires Premium plans.
App-access policies Some installed apps’ access to user-generated content, including Confluence attachments. Coverage and exclusions vary; check the policy against each app and connected tool. Check the documented coverage and the tenant’s available policy controls.

Plan and feature requirements above come from Atlassian’s documentation for anonymous-access policies, attachment-download controls, IP allowlisting, and Confluence page restrictions. Confirm current eligibility and configuration in your own Atlassian tenant.

Test the effective policy after each change

Use test accounts with different permission levels and verify the paths that matter for the content in scope. Atlassian advises testing results when applying controls and overrides; a setting’s label is not proof that all alternate access routes are covered.

  1. Test public and signed-in access to representative spaces, projects, pages, issues, and attachments.
  2. Check whether restricted pages remain inaccessible through inherited links and whether intended users retain access.
  3. Try attachment viewing, supported download buttons, browser-based actions, and API retrieval to confirm what the download policy does and does not block.
  4. Test from allowed and disallowed networks, including relevant previews, notifications, Smart Links, and approved integrations.
  5. Check installed apps and connected tools with the access they actually use, not only through a human user’s browser session.
  6. Record approved exceptions, the person responsible for each one, and an owner and schedule for reviewing permissions and policies.

For policy scope and exceptions, consult Atlassian’s guidance on anonymous access, attachment downloads, and IP allowlisting.
