Atlassian operates the service. To replace Cloudflare’s protections, identify which job you need to retain—sign-in control, network restrictions, SaaS traffic inspection, or configuration visibility—and use a control designed for that job. These controls are complementary, not interchangeable.
Why a conventional edge WAF is not a drop-in replacement
A reverse proxy or WAF protects a web application when traffic to an origin you control passes through that proxy. With Atlassian Cloud, Atlassian operates the application and its origin; your organization does not normally configure a proxy in front of that origin. A WAF you manage for your own proxied website therefore does not automatically filter requests to Jira or Confluence Cloud.
“Edge security” can describe several different safeguards. A replacement plan should name the safeguard being replaced, rather than assume that one new product will reproduce every Cloudflare capability.
Map each Cloudflare function to a control
| Security need | Control to evaluate | What it does and does not establish |
|---|---|---|
| Control who signs in | Atlassian single sign-on (SSO) through an identity provider | Applies identity and sign-in policy through the SaaS application’s SSO configuration; it is not a network-layer WAF. |
| Restrict traffic by source network | Dedicated egress IPs from a secure access service, combined with Atlassian source-IP restrictions if available for your tenant | Can make managed traffic appear to come from known addresses. It works only if the Atlassian tenant supports the relevant allowlist control and traffic consistently uses those egress points. |
| Inspect SaaS-bound traffic | Secure web gateway (SWG) or another secure access service edge (SASE) traffic control | Can route and inspect Internet-bound traffic, including SaaS traffic, subject to the product’s capabilities, policy and device coverage. This is not the same as inserting a WAF in front of Atlassian’s origin. |
| Find risky SaaS settings and access | API-based cloud access security broker (CASB) integration | Can surface configuration and access risks through an authorized SaaS API connection. It does not itself act as a sign-in proxy or inspect every live request. |
Cloudflare’s SASE architecture describes these as distinct methods: SWG inspection, identity proxy/SSO, IP allowlisting with dedicated egress IPs where supported, and API-based CASB. Evaluate each against the requirement it is meant to satisfy, not as a single product-switch comparison. Cloudflare’s SASE architecture overview describes these separate approaches.
#1 Best Overall
Use SSO for identity-based access control
For a third-party SaaS app, Cloudflare says its Access service must integrate with the app’s SSO configuration. Cloudflare’s Atlassian Cloud SAML guide lists four prerequisites: an existing Cloudflare One identity provider, Atlassian administrator access, Atlassian Guard Standard, and a verified Atlassian domain. Check current entitlements and tenant configuration before planning a rollout; these prerequisites are specific to the documented Cloudflare integration, not universal requirements for every identity provider. See Cloudflare’s Atlassian Cloud SAML guide.
If you are replacing Cloudflare rather than implementing its integration, compare candidate identity providers on the same practical questions:
Rank #2
- Does the provider support the SAML or OIDC method configured for your Atlassian tenant?
- Can policy target the right users and groups, and how are existing sessions handled when access changes?
- Can you test the sign-in flow and preserve an emergency administrator path before enforcing SSO broadly?
SSO can enforce who authenticates, but it does not automatically inspect file transfers or reveal risky sharing and third-party app settings. Treat those as separate requirements.
Use network restrictions only when the tenant supports them
A SASE or secure access service may route managed users’ traffic through dedicated egress IP addresses. Where an Atlassian tenant supports source-IP allowlisting, administrators may be able to use those stable egress addresses as an additional access condition. Cloudflare’s SaaS reference architecture describes dedicated egress IPs for SaaS allowlists where the SaaS provider supports the feature, as well as routes for managed remote devices, office traffic and contractors. See Cloudflare’s secure access to SaaS applications with SASE overview.

Confirm the feature and plan entitlement in your own Atlassian administration settings before designing around it. Also confirm which users and devices actually traverse the designated egress points. A restriction based on office addresses alone can leave remote workers or contractors unable to sign in—or create an unintended route around the control.
Use an SWG when the requirement is traffic inspection
An SWG can enforce policies on web traffic routed through it, including traffic to SaaS services. Depending on the selected service and configuration, policies may inspect uploads and downloads or block defined traffic. Ask vendors to demonstrate the exact controls your organization needs, including what is inspected, which devices are covered, and how exceptions behave.
Rank #4
This is a client- and network-side control: it does not place a WAF in front of Atlassian’s hosted origin. Coverage depends on routing traffic from managed devices, offices and contractor environments through the service. Cloudflare’s SASE reference architecture distinguishes remote-device, office and contractor routes, an important deployment consideration when evaluating any replacement.

Use CASB for SaaS posture visibility
CASB integrations address a different gap: identifying potentially risky users, permissions, content or connected apps by connecting to the SaaS service’s APIs. Cloudflare documents integrations for Jira Cloud and Confluence Cloud. Its Jira integration describes findings that include inactive users, third-party app access and oversized attachments; its Confluence integration describes anonymous or unknown user access and third-party app access risks.

Both Cloudflare integration pages specify compatibility with Cloud accounts, not Data Center, and list required administrative permissions and OAuth scopes. Review those permissions with your Atlassian administrators before authorizing an integration. The documented findings are visibility into SaaS configuration and access risks, not proof that the integration blocks every risky action in real time:

Compare options against the controls you actually use today. Ask for current product documentation and a tenant-specific demonstration; an Atlassian integration or feature should not be assumed unless the vendor documents it.
- Identity: SAML or OIDC support, identity-provider compatibility, group and user targeting, and session behavior.
- Device and context: Managed-device posture signals, user identity, and network or location conditions.
- Traffic: Whether SaaS-bound traffic is routed and inspected, whether uploads and downloads are in scope, and what actions policies can take.
- Network restriction: Whether your Atlassian tenant supports source-IP restrictions and whether the service supplies stable, dedicated egress IPs.
- SaaS visibility: API-based insight into users, sharing, third-party apps and risky content permissions; confirm the exact findings and permissions required.
- Prerequisites and operations: Atlassian plan, verified-domain and administrator requirements, end-user sign-in changes, coverage for remote users and contractors, failure modes, and rollback options.
Migration checklist
- Inventory the current protections. Record which Cloudflare controls are used for Atlassian: SSO or Access policy, traffic routing and inspection, source-IP restrictions, CASB findings, or another function.
- Confirm Atlassian tenant capabilities. Check your plan, domain verification, available access restrictions, and the administrator permissions required for the intended integrations.
- Design identity and recovery first. Test SSO with a small group and document an emergency administrator route before enforcing a new sign-in policy tenant-wide.
- Map traffic paths. Verify how managed endpoints, offices and contractors will reach Atlassian, whether intended traffic traverses the SWG, and which egress IPs the tenant will see.
- Review API access before enabling CASB. Check the integration’s requested OAuth scopes and administrator permissions, then confirm that its findings match the risks you need to monitor.
- Pilot and observe. Roll out to a limited group, monitor sign-in failures, routing and policy logs, user impact, and CASB findings. Adjust exceptions before expanding coverage.
- Keep rollback available. Maintain a tested way to restore the previous sign-in or traffic path until the replacement works across each user population.
Keep WAF rules scoped to applications you control
Cloudflare’s WAF IP Access rules documentation recommends custom rules for IP-based blocking and warns that allowing an IP or ASN through IP Access rules bypasses configured custom rules, rate-limiting rules and managed WAF rules. This caveat matters when protecting a web application that you control and proxy through Cloudflare; it is not a mechanism for configuring or protecting Atlassian’s SaaS origin. See Cloudflare’s IP Access rules documentation.
What a replacement can—and cannot—promise
There is no single control in the documented approaches that is shown to reproduce every edge-security function for Atlassian Cloud. SSO controls authentication, an SWG handles routed traffic, supported IP allowlisting restricts network sources, and CASB integrations surface SaaS posture findings. Which combination is appropriate depends on the functions in use and the capabilities and plan entitlements available in your Atlassian tenant.
