Cloudflare One Updates & Release Notes

You can now safely open links in emails to view and investigate them.

Open links with Browser Isolation

From Investigation, go to View details, and look for the Links identified section. Next to each link, the Cloudflare dashboard will display an Open in Browser Isolation icon which allows your team to safely open the link in a clientless, isolated browser with no risk to the analyst or your environment. Refer to Open links to learn more about this feature.

To use this feature, you must:

• Turn on Allow users to open a remote browser without the device client in your Zero Trust settings.
• Have Browser Isolation (RBI) seats assigned.

For more details, refer to our setup guide.

This feature is available across these Email security packages:

• Advantage
• Enterprise
• Enterprise + PhishGuard

A new Browser Isolation Overview page is now available in the Cloudflare Zero Trust dashboard. This centralized view simplifies the management of Remote Browser Isolation (RBI) deployments, providing:

• Streamlined Onboarding: Easily set up and manage isolation policies from one location.
• Quick Testing: Validate clientless web application isolation with ease.
• Simplified Configuration: Configure isolated access applications and policies efficiently.
• Centralized Monitoring: Track aggregate usage and blocked actions.

This update consolidates previously disparate settings, accelerating deployment, improving visibility into isolation activity, and making it easier to ensure your protections are working effectively.

Browser Isolation Overview

To access the new overview, log in to your Cloudflare Zero Trust dashboard ↗︎ and find Browser Isolation in the side navigation bar.

The Cloudflare Zero Trust dashboard ↗︎ now supports Cloudflare's native dark mode for all accounts and plan types.

Zero Trust Dashboard will automatically accept your user-level preferences for system settings, so if your Dashboard appearance is set to 'system' or 'dark', the Zero Trust dashboard will enter dark mode whenever the rest of your Cloudflare account does.

Zero Trust dashboard supports dark mode

To update your view preference in the Zero Trust dashboard:

1. Log into the Zero Trust dashboard ↗︎.
2. Select your user icon.
3. Select Dark Mode.

To update your view preference in the Core dashboard:

1. Log into the Cloudflare dashboard ↗︎.
2. Go to My Profile
3. For Appearance, choose Dark.

Cloudflare One administrators can now control which egress IP is used based on a destination's fully qualified domain name (FDQN) within Gateway Egress policies.

• Host, Domain, Content Categories, and Application selectors are now available in the Gateway Egress policy builder in beta.
• During the beta period, you can use these selectors with traffic on-ramped to Gateway with the WARP client, proxy endpoints (commonly deployed with PAC files), or Cloudflare Browser Isolation.
  • For WARP client support, additional configuration is required. For more information, refer to the WARP client configuration documentation.

Egress by FQDN and Hostname

This will help apply egress IPs to your users' traffic when an upstream application or network requires it, while the rest of their traffic can take the most performant egress path.

You can now use more flexible redirect capabilities in Cloudflare One with Gateway.

• A new Redirect action is available in the HTTP policy builder, allowing admins to redirect users to any URL when their request matches a policy. You can choose to preserve the original URL and query string, and optionally include policy context via query parameters.
• For Block actions, admins can now configure a custom URL to display when access is denied. This block page redirect is set at the account level and can be overridden in DNS or HTTP policies. Policy context can also be passed along in the URL.

Learn more in our documentation for HTTP Redirect and Block page redirect.

With Email security, you get two free CASB integrations.

Use one SaaS integration for Email security to sync with your directory of users, take actions on delivered emails, automatically provide EMLs for reclassification requests for clean emails, discover CASB findings and more.

With the other integration, you can have a separate SaaS integration for CASB findings for another SaaS provider.

Refer to Add an integration to learn more about this feature.

CASB-EmailSecurity

This feature is available across these Email security packages:

• Enterprise
• Enterprise + PhishGuard

We're excited to introduce the Cloudflare Zero Trust Secure DNS Locations Write role, designed to provide DNS filtering customers with granular control over third-party access when configuring their Protective DNS (PDNS) solutions.

Many DNS filtering customers rely on external service partners to manage their DNS location endpoints. This role allows you to grant access to external parties to administer DNS locations without overprovisioning their permissions.

Secure DNS Location Requirements:

• Mandate usage of Bring your own DNS resolver IP addresses ↗︎ if available on the account.

• Require source network filtering for IPv4/IPv6/DoT endpoints; token authentication or source network filtering for the DoH endpoint.

You can assign the new role via Cloudflare Dashboard (Manage Accounts > Members) or via API. For more information, refer to the Secure DNS Locations documentation ↗︎.

A new GA release for the Android Cloudflare One Agent is now available in the Google Play Store ↗︎. This release includes a new feature allowing team name insertion by URL during enrollment, as well as fixes and minor improvements.

Changes and improvements

• Improved in-app error messages.
• Improved mobile client login with support for team name insertion by URL.
• Fixed an issue preventing admin split tunnel settings taking priority for traffic from certain applications.

A new GA release for the iOS Cloudflare One Agent is now available in the iOS App Store ↗︎. This release includes a new feature allowing team name insertion by URL during enrollment, as well as fixes and minor improvements.

Changes and improvements

• Improved in-app error messages.
• Improved mobile client login with support for team name insertion by URL.
• Bug fixes and performance improvements.

Magic Firewall now supports a new managed list of Cloudflare IP ranges. This list is available as an option when creating a Magic Firewall policy based on IP source/destination addresses. When selecting "is in list" or "is not in list", the option "Cloudflare IP Ranges" will appear in the dropdown menu.

This list is based on the IPs listed in the Cloudflare IP ranges ↗︎. Updates to this managed list are applied automatically.

Cloudflare IPs Managed List

Note: IP Lists require a Cloudflare Advanced Network Firewall subscription. For more details about Cloudflare Network Firewall plans, refer to Plans.

Digital Experience Monitoring (DEX) provides visibility into device, network, and application performance across your Cloudflare SASE deployment. The latest release of the Cloudflare One agent (v2025.1.861) now includes device endpoint monitoring capabilities to provide deeper visibility into end-user device performance which can be analyzed directly from the dashboard.

Device health metrics are now automatically collected, allowing administrators to:

• View the last network a user was connected to
• Monitor CPU and RAM utilization on devices
• Identify resource-intensive processes running on endpoints

Device endpoint monitoring dashboard

This feature complements existing DEX features like synthetic application monitoring and network path visualization, creating a comprehensive troubleshooting workflow that connects application performance with device state.

For more details refer to our DEX documentation.

We're excited to announce that new logging capabilities for Remote Browser Isolation (RBI) through Logpush are available in Beta starting today!

With these enhanced logs, administrators can gain visibility into end user behavior in the remote browser and track blocked data extraction attempts, along with the websites that triggered them, in an isolated session.
