Changelog

New updates and improvements at Cloudflare.

Cloudflare One Client for Linux (version 2026.4.1350.0)

A new GA release for the Linux Cloudflare One Client is now available on the stable releases downloads page.

This release introduces the new Cloudflare One Client UI for Linux! You can expect a cleaner and more intuitive design as well as easier access to common actions and information. Here are some of the many things we have found our users appreciate:

  • Right click context menu to access the most common client actions quickly
  • Built-in captive portal login experience

Changes and improvements

  • Added a new CLI command: warp-cli mdm refresh. This command executes an immediate refresh of the Mobile Device Management (MDM) configuration file.
  • Official support for RHEL 9 has been added for Cloudflare Mesh nodes. To install the RHEL 9 package, the Extra Packages for Enterprise Linux (EPEL) repository must be active, as it contains dependencies required for the tray icon and captive portal webview.

Known issues

  • Registration may hang at "Checking your organization configuration" due to IPC errors. A system reboot should resolve the error, allowing registration to proceed.
  • Split tunnel list configuration is not available in the new UI. Management of split tunnel entries is currently only possible via warp-cli tunnel ip and warp-cli tunnel host. UI support will be added in a future release.

NAT-T support for IKE on UDP port 500

Cloudflare IPsec now supports the standard NAT traversal (NAT-T) flow, where IKE begins on UDP port 500 and switches to UDP port 4500 after NAT is detected.

Previously, devices behind NAT had to be configured to initiate IKE on UDP port 4500 directly. Devices that started on UDP port 500 could not complete the IKE handshake when NAT was in the path. This required custom configuration on devices such as VeloCloud SD-WAN edges, Cisco IOS-XE routers, and Juniper SRX firewalls, and was not possible on every platform.

What changed:

  • Devices behind NAT can now initiate IKE on either UDP port 500 or UDP port 4500.
  • Devices that start IKE on UDP port 500 and switch to UDP port 4500 after NAT detection now complete the handshake successfully.
  • No configuration change is required on Cloudflare. The change is available for all IPsec tunnels on Cloudflare WAN and Magic Transit.

This change does not affect existing tunnels:

  • Tunnels using UDP port 500 with no NAT detected continue to operate as before.
  • Tunnels configured to start IKE on UDP port 4500 continue to operate as before.
  • NAT detection logic is unchanged.

For configuration details, refer to GRE and IPsec tunnels.

WAF Release - 2026-05-11

Key Findings

  • Existing rule enhancements have been deployed to improve detection resilience against broad classes of web attacks and strengthen behavioral coverage.

Continuous Rule Improvements

We are continuously refining our managed rules to provide more resilient protection and deeper insights into attack patterns. To ensure an optimal security posture, we recommend consistently monitoring the Security Events dashboard and adjusting rule actions as these enhancements are deployed.

WAF and framework adapter mitigations for React and Next.js vulnerabilities

Multiple security vulnerabilities were disclosed by the React team and Vercel affecting React Server Components and Next.js. These include denial of service, middleware and proxy bypass, server-side request forgery, cross-site scripting, and cache poisoning issues across a range of severity levels.

We strongly recommend updating your application and its dependencies immediately. Patched versions are available for React (react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack 19.0.6, 19.1.7, and 19.2.6) and Next.js (15.5.16 and 16.2.5).

WAF protections

Cloudflare WAF rules deployed in response to prior React Server Component CVEs (CVE-2025-55184 and CVE-2026-23864) already provide coverage for the newly disclosed denial-of-service vulnerabilities. These rules are enabled by default with a Block action for all customers using the Cloudflare Managed Ruleset, including Free plan customers using the Free Managed Ruleset.

Ruleset Rule description Rule ID Default action
Cloudflare Managed Ruleset React - DoS - CVE-2025-55184 2694f1610c0b471393b21aef102ec699 Block
Cloudflare Managed Ruleset React - DoS - CVE-2026-23864 aaede80b4d414dc89c443cea61680354 Block

The existing rules detect the underlying attack patterns generically. As a result, they apply to the new CVE-2026-23870 denial-of-service vulnerability in Server Components and the corresponding Next.js advisory GHSA-8h8q-6873-q5fj.

Cloudflare is investigating whether WAF rules can be safely and effectively deployed for three of the high-severity advisories: CVE-2026-23870 / GHSA-8h8q-6873-q5fj, GHSA-267c-6grr-h53f, and GHSA-mg66-mrh9-m8jx. If it is possible to create a managed WAF rule that mitigates these CVEs and does not potentially break application behavior, Cloudflare will add additional managed WAF rules. These rules will be announced through the WAF changelog. Because these vulnerabilities were shared with Cloudflare with minimal advance notice, we are still investigating what WAF mitigations are possible.

Several of the disclosed vulnerabilities are not possible to block in WAF. We strongly recommend updating your applications so they are not purely reliant on WAF mitigations.

Customers on Pro, Business, or Enterprise plans should ensure that Managed Rules are enabled.

Next.js adapters

Vinext: Vinext is a Vite plugin that reimplements the Next.js API surface. Vinext's latest release is not vulnerable to any of the disclosed CVEs. Vinext's architecture differs from stock Next.js in ways that sidestep the affected code paths. For example, it does not implement the PPR resume protocol, does not expose Pages Router data-route endpoints, and strips internal headers such as x-nextjs-data at request boundaries. As an extra layer of defense, we added a React 19.2.6 or later requirement when running vinext init (PR #1118, PR #1112) to prevent accidentally running a vulnerable version of React with Vinext.

OpenNext on Cloudflare: OpenNext is an adapter that lets you deploy Next.js apps to the Cloudflare Workers platform. OpenNext itself is not directly vulnerable to the React denial-of-service CVE, but users must update the Next.js version in their application. The OpenNext team has updated the adapter to further harden against these vectors and released a new version of the Cloudflare adapter. Test fixtures and examples have been updated to use patched versions (PR #1255).

Custom DHCP options on Cloudflare One Appliance

When the Cloudflare One Appliance is acting as the DHCP server for a LAN, you can now configure custom DHCP options on the leases it issues. This unlocks workflows such as PXE / iPXE boot, VoIP phone provisioning, and vendor-specific client configuration.

Each option is defined by option_number, value, and one of four value types: text, integer, hex, or ip. Configurations are validated on the appliance before being applied — invalid configurations are rejected and the underlying error is returned to the API caller, so a bad option will not disrupt the live DHCP service.

For details, refer to DHCP server options.

Source-based breakout and prioritization on Cloudflare One Appliance

Breakout and traffic prioritization rules on the Cloudflare One Appliance can now match by source in addition to destination application. You can pin breakout or priority behavior to:

  • A source LAN interface — VLANs attached to that LAN are included automatically.
  • A source IP address, range, or CIDR block.

This is the natural way to break out a guest VLAN to the local Internet, or to prioritize traffic from a specific subnet, without enumerating destination applications.

For details, refer to Breakout traffic.

Self-serve provisioning of Cloudflare One Virtual Appliance via API

You can now create, rotate, and delete Cloudflare One Virtual Appliance instances and their license keys directly via the API and Terraform.

  • Create a virtual appliance and receive a license key: POST /accounts/{account_id}/magic/connectors with device.provision_license: true.
  • Rotate the license key for an existing virtual appliance: PATCH /accounts/{account_id}/magic/connectors/{connector_id} with provision_license: true. The previous key is immediately and irrevocably revoked.
  • Delete a virtual appliance to release the associated licensed device.

The license key is returned in the response only once, at create or rotate time. Copy and store it securely.

For details, refer to Configure a Cloudflare One Virtual Appliance.

CSV export and adjustable page density for RFIs

You can now export your Requests for Information (RFI) history to a CSV document and customize your dashboard view by choosing how many RFI records to load per page.

Why this matters

These quality-of-life updates focus on data portability and dashboard performance, allowing power users to manage high volumes of requests more efficiently:

  • The new CSV export allows you to move RFI data into external tools for custom reporting, internal auditing, or cross-referencing with other security projects without manual data entry
  • With adjustable page density, you can now choose to load more records at once (10, 25 or 50) to scan through history faster

Cloudforce One subscribers can find these new options in Cloudflare Dashboard > Application Security > Threat Intelligence > Requests for Information.

Introducing Stream Bindings for Workers

You can now interact with your Stream video library using new bindings for Workers! This allows customers to upload content to Stream, provision direct uploads, manage videos, and generate signed URLs from a Worker without making authenticated API calls. We're excited to bring Stream and Workers closer together to empower more programmatic pipelines, tighter integrations, and support generative AI and inference workloads.

Use the Stream binding when you want to:

  • Upload videos from URLs or create basic direct upload links for end users
  • Generate signed playback tokens without managing signing keys
  • Manage video metadata, captions, downloads, and watermarks
  • Build video pipelines entirely within Workers

To get started, add the Stream binding to your Wrangler configuration:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "stream": {
    "binding": "STREAM"
  }
}
[stream]
binding = "STREAM"

Generate a video with AI and upload directly to Stream or send a URL of a file you already have:

const aiResponse = await env.AI.run(
	"google/veo-3.1",
	{
		prompt: "A dog walking next to a river",
		duration: "10s",
		aspect_ratio: "16:9",
		resolution: "1080p",
		generate_audio: true,
	},
	{
		gateway: { id: "experiments" },
	},
);

// Veo will return a URL of the generated asset.
const videoUrl = aiResponse.result.video;

// Alternative option: a video of the Austin Office mobile
// const videoUrl = 'https://pub-d9fcbc1abcd244c1821f38b99017347f.r2.dev/aus-mobile.mp4';

// Upload to Stream by providing a URL
const streamVideo = await env.STREAM.upload(videoUrl);

// The streamVideo response will include the video ID, playback and manifest
// URLs, and other information, just like the REST API.
const aiResponse = await env.AI.run(
	'google/veo-3.1',
	{
		prompt: 'A dog walking next to a river',
		duration: '10s',
		aspect_ratio: '16:9',
		resolution: '1080p',
		generate_audio: true,
	},
	{
		gateway: { id: 'experiments' },
	},
);

// Veo will return a URL of the generated asset.
const videoUrl = aiResponse.result.video;

// Alternative option: a video of the Austin Office mobile
// const videoUrl = 'https://pub-d9fcbc1abcd244c1821f38b99017347f.r2.dev/aus-mobile.mp4';

// Upload to Stream by providing a URL
const streamVideo = await env.STREAM.upload(videoUrl);

// The streamVideo response will include the video ID, playback and manifest
// URLs, and other information, just like the REST API.

Generate a signed URL without using a signing key or an API call:

const video_id = "ce800be43a9772f4bb02f35b860fb516";
const token = await env.STREAM.video(video_id).generateToken();

// Use the "token" in an iframe embed code, manifest URL, or thumbnail:
const embedUrl = `https://customer-igynxd2rwhmuoxw8.cloudflarestream.com/${token}/iframe`;
const video_id = 'ce800be43a9772f4bb02f35b860fb516';
const token = await env.STREAM.video(video_id).generateToken();

// Use the "token" in an iframe embed code, manifest URL, or thumbnail:
const embedUrl = `https://customer-igynxd2rwhmuoxw8.cloudflarestream.com/${token}/iframe`;

Get and set video properties easily:

const video_id = "46c8b7f480d410840758c1cb14a72e47";
const result = await env.STREAM.video(video_id).details();

await env.STREAM.video(video_id).update({
	meta: { name: "sample video" },
});
const video_id = '46c8b7f480d410840758c1cb14a72e47';
const result = await env.STREAM.video(video_id).details();

await env.STREAM.video(video_id).update({
  meta: { name: 'sample video' }
});

For setup instructions and the full API reference, refer to Bind to Workers API.

Get started with your Agent

Add a binding for Cloudflare Stream (env.STREAM). On the watch page, use the Stream binding to get info based on the ID, and leverage video.meta.name as the page title.

WAF Release - 2026-05-07 - Emergency

This emergency release introduces a new rule to detect Next.js App Router middleware and proxy bypass attempts via segment-prefetch routes (CVE-2026-44575).

Key Findings

CVE-2026-44575: Next.js Middleware / Proxy Bypass in App Router Applications via Segment-Prefetch Routes

Successful exploitation allows unauthenticated attackers to bypass middleware or proxy-based authorization checks in affected Next.js App Router applications. This leads to unauthorized access to protected content, potential exposure of sensitive application data, and compromise of application security boundaries.

We strongly recommend upgrading to Next.js 15.5.16 or 16.2.5 (or later) immediately to address the underlying vulnerability. If you cannot upgrade immediately, enforce authorization in the underlying route or page logic instead of relying solely on middleware.

RulesetRule IDLegacy Rule IDDescriptionPrevious ActionNew ActionComments
Cloudflare Managed RulesetN/ANext.js - Middleware Bypass via Invalid RSC Header - CVE:CVE-2026-44575N/ADisabled

This is a new detection.

Automatic tracing across Durable Object and Worker subrequests

You can now get a single unified trace across Worker-to-Worker subrequests, with trace context propagating automatically. Previously, automatic tracing produced disconnected traces when a Worker called another Worker through a service binding or Durable Object.

Unified trace showing nested spans across a Durable Object subrequest and a service binding call

This means you can:

  • Follow a request through your entire Worker architecture in one trace view
  • See service binding and Durable Object calls as nested child spans instead of separate traces
  • Debug cross-Worker request flows in the Cloudflare dashboard or in an external observability platform via OpenTelemetry

Tracing must be enabled in your Wrangler configuration for traces to be recorded. Checkout Workers tracing to get started.

Up next, we are working on external trace context propagation using W3C Trace Context standards, which will allow traces from your Workers to link with traces from services outside of Cloudflare.

Cloudy Summaries in PhishNet O365

PhishNet users can now access Cloudy summaries directly within the email investigation experience. When reviewing a message in PhishNet, users will see an AI-generated summary that provides additional context and key details about the email.

These summaries help users quickly understand the nature of a message without needing to manually parse through headers, body content, and detection signals. Cloudy surfaces the most relevant information so users can make faster, more informed decisions about suspicious emails.

These summaries are not trained on customer data. They are generated using the outputs of our existing detection models and analysis systems.

This feature is available for PhishNet with Office 365. Support for Gmail will be available by the end of the quarter.

TLD Nameserver Performance in Cloudflare Radar

Radar now provides TLD authoritative nameserver performance insights, measuring response time (latency) as observed from Cloudflare's 1.1.1.1 resolver infrastructure when forwarding queries upstream to TLD nameservers.

New widgets on TLD detail pages:

Latency per nameserver chart TLD Rankings by DNS Magnitude table with rank change deltas

The new TLD Performance API provides the following endpoints:

Available dimensions: LATENCY (aggregate p25/p50/p75), NAMESERVER_LATENCY (per-nameserver p50), LOCATION_LATENCY (per-data-center-country p50).

TLD Performance is also available as a dataset in the Data Explorer.

Check out the updated TLD detail page.

TAXII support added to Threat Events API

The Cloudforce One Threat Events API now supports TAXII as an output format, enabling standardized, automated sharing of cyber threat intelligence with your existing security stack.

Why this matters

  • You can now ingest Cloudforce One threat data directly into your SIEM, TIP or SOAR tools that prefer TAXII-formatted streams without needing custom translation scripts.
  • By supporting the TAXII format parameter in our API, security teams can automate the synchronization of indicator data, reducing the manual overhead of updating blocklists and detection rules.
  • This alignment with industry standards ensures that your threat data remains consistent across different security ecosystems and partner integrations.

How to use it

When calling the Threat Events API, you can now specify taxii in the format query parameter:

GET /accounts/{account_id}/cloudforce_one/threat_events?format=taxii

You can find the updated documentation in the Cloudflare API Reference.

Pingora now powers Cloudflare's cache

Cloudflare's cache now runs on a new proxy built on Pingora, the Rust-based framework that already serves a significant portion of Cloudflare's network traffic. The new proxy is faster, more memory-safe, and designed to evolve our cache architecture. It delivers immediate performance improvements and enables new caching capabilities.

What this brings

  • Lower latency: The new proxy reduces per-request overhead through improved connection reuse.
  • Reduced cache MISSes: Enhanced cache retention improves origin offload.
  • Better RFC compliance: Caching behavior more closely follows HTTP caching standards.
  • Foundation for future features: The new architecture enables upcoming improvements to cache functionality and efficiency.

New features

  • Asynchronous stale-while-revalidate: Every request returns stale content immediately while revalidation happens in the background, instead of the first request after expiry blocking on the origin. Refer to the asynchronous stale-while-revalidate changelog for details.
  • Unbuffered bypass by default: Responses that bypass cache are streamed directly to the client without buffering, reducing time-to-first-byte for uncacheable content.

Behavioral changes

The new architecture introduces the following behavioral changes to improve RFC compliance and correctness:

  • Vary: * results in cache bypass: According to RFC 9110 Section 12.5.5, a Vary header value of * indicates the response varies on factors beyond request headers and must not be served from cache. Cloudflare now bypasses cache for these responses instead of storing them.
  • Set-Cookie stripped on MISS and EXPIRED: For cacheable assets, Set-Cookie is now stripped on MISS and EXPIRED responses, not only on HITs.
  • Floating-point TTL values: Floating-point time-to-live values (for example, max-age=1.5) are rounded down to the nearest integer instead of being rejected as invalid.

What's next

A deeper look at the new cache proxy is coming soon to the Cloudflare blog. For background on the underlying framework, read:

Pipelines and R2 Data Catalog now supported in Terraform

Cloudflare Pipelines ingests streaming data via Workers or HTTP endpoints, transforms it with SQL, and writes it to R2 as Apache Iceberg tables. R2 Data Catalog manages those Iceberg tables, compaction, and compatibility with query engines like R2 SQL, Spark, and DuckDB.

You can now create and manage both products using Terraform, supported in the Cloudflare Terraform provider v5.19.0.

This adds four new resources that let you define your entire data pipeline as infrastructure-as-code: a data catalog, a stream for ingestion, a sink that writes to R2 Data Catalog or R2, and a pipeline that connects them with SQL.

The new Terraform resources are:

Here is a minimal example that creates a stream, an R2 Data Catalog sink, and a pipeline:

resource "cloudflare_pipeline_stream" "my_stream" {
  account_id = var.cloudflare_account_id
  name       = "my_stream"
  format     = { type = "json" }
  schema = {
    fields = [{
      name     = "value"
      type     = "json"
      required = true
    }]
  }
  http           = { enabled = true, authentication = false, cors = {} }
  worker_binding = { enabled = false }
}

resource "cloudflare_pipeline_sink" "my_sink" {
  account_id = var.cloudflare_account_id
  name       = "my_sink"
  type       = "r2_data_catalog"
  format     = { type = "parquet" }
  schema     = { fields = [] }
  config = {
    account_id = var.cloudflare_account_id
    bucket     = "my-pipeline-bucket"
    table_name = "my_table"
    token      = var.catalog_token
  }
}

resource "cloudflare_pipeline" "my_pipeline" {
  account_id = var.cloudflare_account_id
  name       = "my_pipeline"
  sql        = "INSERT INTO ${cloudflare_pipeline_sink.my_sink.name} SELECT * FROM ${cloudflare_pipeline_stream.my_stream.name}"
}

For a full end-to-end example that includes R2 bucket creation, data catalog setup, and scoped API token provisioning, refer to the Pipelines Terraform documentation.

New routing widgets on Cloudflare Radar

Radar is expanding its Routing section with two new widgets that give a deeper view into how networks announce address space and how RPKI ROA coverage evolves over time.

Top ASes by announced IP space on country pages

Country routing pages now include a Top ASes by announced IP space chart, breaking down the IPv4 and IPv6 address space announced from a country across the autonomous systems that originate it. The chart stacks the IPv4 and IPv6 views vertically, with the top contributing ASes called out by color and the remaining networks aggregated as Other.

Screenshot of the top ASes by announced IP space chart on a country routing page

RPKI ROA deployment timeseries

The RPKI sub-page adds an RPKI ROA deployment timeseries widget that tracks the share of announced BGP space covered by a valid Route Origin Authorization (ROA) over time, with separate IPv4 and IPv6 lines. A toggle switches the view between the share of covered prefixes and the share of covered IP address space. The widget is available on global, country, and AS views, so operators can monitor RPKI adoption progress and compare deployment trends across different scopes.

Screenshot of the RPKI ROA deployment timeseries widget

API endpoints

The data behind these widgets is also available through two new endpoints on the BGP API:

  • /bgp/ips/top/ases - Returns the top autonomous systems by announced IP space (IPv4 /24s or IPv6 /48s), globally or filtered by country, snapped to the nearest 8-hour RIB boundary.
  • /bgp/rpki/roas/timeseries - Returns RPKI ROA validation coverage over time, by share of prefixes or share of IP address space, split by IP version, with optional ASN or location filters.

Visit the Radar routing section to explore both widgets.

WAF Release - 2026-05-04

This week's release focuses on new detections to expand coverage across command injection, SQL injection, PHP object injection, remote code execution, and XSS attack vectors.

Key Findings

  • Existing rule enhancements have been deployed to improve detection resilience against broad classes of web attacks and strengthen behavioral coverage.

Continuous Rule Improvements

We are continuously refining our managed rules to provide more resilient protection and deeper insights into attack patterns. To ensure an optimal security posture, we recommend consistently monitoring the Security Events dashboard and adjusting rule actions as these enhancements are deployed.

Run Workflows inside Dynamic Workers with the @cloudflare/dynamic-workflows library

You can now use @cloudflare/dynamic-workflows to run a Workflow inside a Dynamic Worker, ensuring durable execution for code that is loaded at runtime.

The Worker Loader loads Dynamic Workers on demand, which previously made durability challenging. Even within a Dynamic Worker, a Workflow might sleep for hours or days between steps, and by the time it resumes, the original Dynamic Worker code would no longer be in memory.

The library solves this by tagging each Workflow instance with metadata that identifies which Dynamic Worker to load — for example, a tenant ID — then reloading the matching Dynamic Worker through the Worker Loader whenever a Workflow awakens.

Because Dynamic Workers are created on-demand, you do not have to register each Workflow up front or manage them individually. Load the Workflow code in the Dynamic Worker when it is needed, and the Workflows engine handles persistence and retries behind the scenes. Your Workflow code itself is unaffected by the routing and behaves as normal.

This unlocks patterns where the Workflow code itself is dynamic. For example, this is useful with:

  • SaaS platforms where each tenant defines their own automation, such as onboarding sequences, approval chains, or billing retry logic.
  • AI agent frameworks where agents generate and execute multi-step plans at runtime, surviving restarts and waiting for human approval between tool calls.
  • Multi-tenant job systems where each customer submits their own processing logic and every step persists progress and retries on failure.
import {
	createDynamicWorkflowEntrypoint,
	DynamicWorkflowBinding,
	wrapWorkflowBinding,
	type WorkflowRunner,
} from "@cloudflare/dynamic-workflows";

export { DynamicWorkflowBinding };

interface Env {
	WORKFLOWS: Workflow;
	LOADER: WorkerLoader;
}

function loadTenant(env: Env, tenantId: string) {
	return env.LOADER.get(tenantId, async () => ({
		compatibilityDate: "2026-01-01",
		mainModule: "index.js",
		modules: { "index.js": await fetchTenantCode(tenantId) },
		// The Dynamic Worker uses this exactly like a real Workflow binding;
		// every create() is tagged with { tenantId } automatically.
		env: { WORKFLOWS: wrapWorkflowBinding({ tenantId }) },
	}));
}

// The entrypoint name must match `class_name` in the workflows binding of your Wrangler config file.
export const DynamicWorkflow = createDynamicWorkflowEntrypoint<Env>(
	async ({ env, metadata }) => {
		const stub = loadTenant(env, metadata.tenantId as string);
		return stub.getEntrypoint("TenantWorkflow") as unknown as WorkflowRunner;
	},
);

export default {
	fetch(request: Request, env: Env) {
		const tenantId = request.headers.get("x-tenant-id")!;
		return loadTenant(env, tenantId).getEntrypoint().fetch(request);
	},
};

Post-quantum IPsec interoperability with third-party devices

Cloudflare IPsec now supports post-quantum key agreement with compatible third-party devices. Cisco and Fortinet are the first third-party vendors validated to interoperate with Cloudflare IPsec using ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism).

Post-quantum IPsec uses RFC 9370 and draft-ietf-ipsecme-ikev2-mlkem to negotiate hybrid key agreement during the IKEv2 IKE_INTERMEDIATE phase. This combines classical Diffie-Hellman (Group 20) with ML-KEM-768 or ML-KEM-1024 to protect against harvest-now, decrypt-later attacks.

Key details:

  • Compatible with Cisco 8000 Series Secure Routers with IOS XR Release 26.1.1 and Fortinet FortiOS 7.6.6 and later.
  • Uses ML-KEM-768 or ML-KEM-1024 as an additional Key Exchange to DH Group 20.
  • Follows RFC 9370 and draft-ietf-ipsecme-ikev2-mlkem standards.
  • No additional licensing required.

Post-quantum IPsec with third-party devices is now generally available with confirmed interoperability for the platforms listed above. Cloudflare intends to support interoperability with more vendors as they build out support for draft-ietf-ipsecme-ikev2-mlkem. Contact your account team to discuss support for additional vendors.

For supported key exchange methods and the list of validated platforms, refer to GRE and IPsec tunnels.

Classify sensitive content with Data Classification

Cloudflare DLP now includes Data Classification, which lets administrators organize and label sensitive content using labels, templates, and reusable data classes.

With Data Classification, administrators can define labels such as sensitivity schemas and levels, and data tag groups and tags. Administrators can also build from Cloudflare-managed templates and create reusable data classes that combine detection entries, other data classes, sensitivity levels, and data tags.

You can then use those classifications in custom DLP profiles to identify the severity of sensitive content, understand where it exists, and apply that logic consistently across DLP profiles.

For more information, refer to Data Classification.
