Give every teammate and agent the right level of access to your Workers

Cloudflare launches per-Worker granular access controls with four roles, enabling least-privilege access for teammates, AI agents, and CI/CD pipelines.

Cloudflare announced granular authorization for Workers, letting admins scope access to a single Worker instead of the whole account. Four new roles are available: Metadata Read-Only (observability without source code), Content Read-Only (read code without changes), Editor (deploy without delete), and Admin (full control of one Worker). Roles apply at Developer Platform, product, or resource level, can be attached to dashboard users or API tokens, and are available to all customers now, with plans to extend to D1, R2, and KV.

Have it both ways: stay discoverable in search while disallowing AI training

Cloudflare launches Disallow AI Training setting letting sites block AI training via robots.txt while staying indexed in search; Apple, Google, and Microsoft honor it.

Cloudflare announced a 'Disallow AI Training' setting that publishes a no-training preference in robots.txt so sites can block AI training (including by mixed-use crawlers) without losing search indexing. Apple, Google, and Microsoft meet Cloudflare's new 'Accountable' designation, which requires training/summary opt-out mechanisms, URL-level training visibility, and assurance that opt-outs don't affect search rankings. Cloudflare cites that under 1% of its sites block search bots while 17% block AI training, and its Block settings now apply to mixed-use crawlers as well. Granular controls over how much content appears in AI summaries are planned for early next year.

Introducing automatic remediation policies with Cloudflare CASB

Cloudflare CASB now offers automatic remediation policies that revoke risky SaaS file shares or trigger webhooks within five minutes of detection.

Cloudflare introduced automatic remediation policies for its CASB product, letting security teams define event-driven logic that revokes risky file shares, dispatches custom webhooks, or forwards findings to SOAR platforms without manual intervention. Native remediation actions currently support Microsoft and Google Workspace file and folder findings, with a target of completing remediation within five minutes of detection. The engine is built on the Cloudflare developer platform, using Cloudflare Queues, Workers and Workflows for durable execution with automatic retries and rate-limit backoff.

1.1.1.1 now supports post-quantum DNSSEC, all 2,420 bytes of it

Cloudflare's 1.1.1.1 resolver now validates post-quantum DNSSEC signatures using ML-DSA-44, a 2,420-byte NIST algorithm, preparing DNS for post-quantum migration by 2029.

Cloudflare enabled 1.1.1.1 to validate DNSSEC signatures using ML-DSA-44 (algorithm 18), a NIST-standardized post-quantum signature with 1,312-byte public keys and 2,420-byte signatures, roughly 38x larger than ECDSA P-256. The large signatures exceed common DNS-over-UDP limits, forcing fallback to TCP and creating downgrade risks while conventional algorithms must be published alongside. Cloudflare cites the risk of a quantum computer breaking RSA/ECDSA signatures by 2030 and plans full post-quantum security by 2029.

Introducing context-aware vulnerability discovery and remediation with Cloudflare Managed Defense and OpenAI Daybreak models

Cloudflare launches invitation-only Vulnerability Discovery and Remediation within Managed Defense, using OpenAI Daybreak models and WAF context to prioritize and patch vulnerabilities.

Cloudflare announced early access to Vulnerability Discovery and Remediation, an invitation-only service within Cloudflare Managed Defense. The service uses OpenAI Daybreak models, including GPT-5.6 Cyber, via the Daybreak Defense Network to hunt and validate vulnerabilities in customer-authorized codebases across Workers and proxied applications. Findings are prioritized using production traffic, WAF rule, and security event context, and proposed patches and WAF mitigations are automatically checked before customer review.

Introducing Adaptive Intelligence: Undermining the economics of every bot attack

Cloudflare launches Adaptive Intelligence, an engine that autonomously learns live-traffic meta-signals and deploys disposable rules to raise bot attack costs.

Cloudflare introduced Adaptive Intelligence, a bot-management engine that autonomously learns meta-signals from live traffic and deploys disposable detection rules. The company says static, deterministic rules historically let bot operators keep attacks cheap by using cheap proxies and rapid retooling. The new approach aims to make automated bot attacks economically unsustainable to sustain.

Say it once: Introducing Bot Preference Sync

Cloudflare launched Bot Preference Sync, which automatically syncs robots.txt files with AI bot policies covering search, agent, and training crawlers.

Cloudflare's new Bot Preference Sync feature automatically aligns a site's robots.txt with its configured AI bot policies for Search, Agent, and Training bot categories. The goal is to let site owners manage which automated and AI crawlers access their content without manually maintaining static robots.txt files.

From all-or-nothing to task-based OAuth consent

Cloudflare OAuth adds optional scopes and task-based consent, letting users limit what apps can access per task.

Cloudflare announced that its OAuth support now includes optional scopes, moving away from all-or-nothing consent models. Users gain finer-grained control over what an application can access, and developers can build secure consent flows scoped to the specific task being authorized.
