What is Attention Required! | Cloudflare

Attention Required! | Cloudflare is the standard interstitial page shown by Cloudflare when a website’s security configuration triggers an automated browser verification. The interstitial uses JavaScript-based challenges, cookie checks and optional CAPTCHA prompts to verify that the incoming request comes from a real browser and not an automated agent. It appears when Cloudflare's firewall rules, DDoS protection, or bot management settings determine additional verification is required before serving the protected site.

This mechanism is not a standalone product you install; it is part of Cloudflare’s edge security stack and executes at the network edge in front of the origin server. The page is generated automatically by Cloudflare’s edge servers when a request meets a configured condition (for example, suspicious request patterns, rate limits, or custom firewall rules). The interstitial typically completes within a few seconds for normal browsers and clears the visitor by setting session cookies or tokens.

Cloudflare exposes the behavior and controls for these challenges through its dashboard and API, allowing site administrators to tune sensitivity, enable or disable JavaScript challenges, configure CAPTCHA triggers, and map challenge outcomes to custom firewall rules. For technical guidance on how these checks operate and troubleshooting steps, see Cloudflare’s security challenge documentation: their security challenge documentation on support.cloudflare.com.

What does Attention Required! | Cloudflare do?

Attention Required! | Cloudflare verifies that a visitor is a legitimate browser session before serving content from a site protected by Cloudflare. It runs client-side JavaScript tests, checks for cookie support, and optionally adds CAPTCHA steps when a request is flagged as risky by Cloudflare’s rules or threat intelligence. Successful completion results in a short-lived cookie or token that tells Cloudflare to allow subsequent requests without repeating the check for that session.

The feature integrates with other Cloudflare capabilities: firewall rules determine when to trigger the interstitial; the bot management system analyzes behavioral signals to escalate checks; and rate limiting can force challenge flows for high-frequency clients. Administrators can tune thresholds and exemptions (for example, whitelisting known good IPs or API clients) so that only potentially harmful traffic is challenged.

From an end-user perspective, the challenge is normally seamless: compliant browsers automatically run the required scripts and proceed to the site. From an operator’s perspective, it reduces noise to the origin by stopping automated scanners, credential stuffing attempts, and certain bot-driven DDoS patterns at the edge.

Additional capabilities include challenge logging and analytics in the Cloudflare dashboard, which help administrators see how many checks are issued, how often CAPTCHAs are presented, and which rules cause the most challenges.

What is Attention Required! | Cloudflare used for

Attention Required! | Cloudflare is used primarily to stop automated or risky requests at Cloudflare’s network edge before they reach the origin server. Typical use cases include blocking credential-stuffing attacks, reducing bot-driven scraping, mitigating layer 7 DDoS patterns, and enforcing rate limits. It acts as a lightweight gate that reduces backend load and limits exposure to abusive traffic.

Site owners use the interstitial as part of a layered defense: firewall rules and bot management detect suspicious patterns, the challenge verifies the client, and allowed sessions are tokenized so legitimate users have uninterrupted access. This reduces false positives while maintaining a security posture appropriate for public-facing services.

Developers and operations teams rely on related telemetry—challenge logs, blocking counts, and request metadata—to refine firewall rules and tune how aggressively Cloudflare applies challenges. The flow is particularly useful for sites that must remain accessible globally but need a mechanism to throttle or verify unknown clients.

Pros and cons of Attention Required! | Cloudflare

Pros:

• Deployment at the edge reduces load on origin infrastructure by intercepting malicious or automated requests early.
• The client-side checks are mostly transparent to modern browsers, producing minimal friction for legitimate users while blocking many automated tools.
• Integration with Cloudflare’s firewall, bot management and analytics gives operators actionable controls and visibility to tune protection.
• Can be configured to escalate to CAPTCHA only when automated detection algorithms determine risk, balancing user experience and security.

Cons:

• Some legitimate automated clients (API consumers, headless browsers, crawlers) may be accidentally challenged unless explicitly exempted or configured with proper authentication.
• Very old browsers, restrictive privacy settings, or privacy-focused extensions that block JavaScript or cookies can be unable to pass the check, causing user friction.
• For highly customized verification needs, site operators may need Enterprise-level controls or custom responses, which increases cost and contract complexity.
• Depending on global configuration, the interstitial may add a small delay for first-time visitors while the browser completes verification.

Operational considerations include carefully planning rule sensitivity, implementing exemptions for known API clients or partner IPs, and monitoring challenge analytics to minimize false positives.

Attention Required! | Cloudflare free trial

Cloudflare provides a tiered model rather than a traditional limited-time free trial for enterprise-grade features. The Free Plan is a permanently available option that offers basic protections and the underlying challenge behavior in many cases. Higher tiers—Starter, Professional and Enterprise—unlock expanded WAF rules, enhanced bot management, and advanced support.

Organizations evaluating higher tiers can typically enable a paid plan and test it in production; Cloudflare’s documentation and onboarding resources explain configuration steps for WAF rules, challenge behavior and logging. In some cases Cloudflare’s sales team or partner network will arrange trial access or proof-of-concept periods for Enterprise services.

For planned evaluations, Cloudflare encourages testing in a staging environment or enabling stricter logging so you can tune challenge thresholds before applying aggressive blocking rules to production traffic. See Cloudflare’s guidance on migrating between plans and testing security controls in their plans and pricing documentation.

Is Attention Required! | Cloudflare free

Yes, the core challenge behavior is available to accounts on Cloudflare’s Free Plan. The Free Plan provides baseline DDoS mitigation, CDN caching and basic firewall rules that can trigger interstitial challenges for suspicious requests. Advanced bot management, richer analytics, and custom challenge controls are available at paid tiers.

Attention Required! | Cloudflare API

Cloudflare exposes a comprehensive REST API that covers zone settings, firewall rules, rate limiting, and more—these APIs let administrators control when and how challenges are applied. Common endpoints used to manage challenge behavior include the Firewall Rules API, Zone Settings API (where you can toggle security levels and challenge settings), and the WAF API for rule management. Developers can automate responses such as adding IP white/blacklists, adjusting challenge sensitivity, or programmatically inspecting challenge logs.

The API is authenticated with API tokens or API keys and supports role-based access control, allowing limited-permission tokens for automation tasks. For technical reference and code examples, see Cloudflare’s API docs at their API documentation site.

Programmatic management is useful for dynamic environments: for example, CI/CD systems can automatically add temporary firewall exceptions during maintenance windows, or security tools can enact emergency rules in response to detected incidents. Integrations commonly use the API to combine Cloudflare telemetry with SIEM tools or to correlate challenge events with origin-side logs.

Frequently asked questions about Attention Required! | Cloudflare

What is Attention Required! | Cloudflare used for?

Attention Required! | Cloudflare is used for verifying visitors before granting access to a site. It reduces automated and abusive requests by running client-side checks (JavaScript challenges and optional CAPTCHAs) so that only legitimate browser sessions reach the origin server. Operators use it to mitigate credential stuffing, bot scraping and some layer 7 DDoS patterns.

How does Attention Required! | Cloudflare determine when to show the challenge?

Cloudflare triggers the challenge based on firewall rules, threat signals, and bot management heuristics. The platform analyzes request attributes—rate, origin IP reputation, behavior fingerprints and rule matches—and issues a challenge when a request meets configured risk criteria. Administrators can tune those rules and add exemptions for known good clients.

Does Attention Required! | Cloudflare block legitimate users?

Occasionally, legitimate users can be challenged if their browser blocks JavaScript or cookies. Most modern browsers pass the checks transparently, but very old browsers, privacy extensions, or headless clients may fail and require an alternative access method or whitelist. Operators should monitor challenge logs and provide exemptions for trusted services.

Can I customize the challenge behavior for my site?

Yes, challenge behavior is configurable via Cloudflare’s dashboard and API. Administrators can adjust firewall rules, set security levels, configure CAPTCHA triggers, and whitelist IPs or user agents to reduce false positives. Enterprise customers receive additional customization and support.

Is Attention Required! | Cloudflare part of a paid plan?

The underlying challenge capability is available on Cloudflare’s Free Plan, with advanced controls available in paid tiers. Basic interstitial behavior can appear for accounts on the Free Plan; upgrading to paid tiers such as Starter or Professional grants additional WAF features, advanced bot management and enhanced analytics.

Why did I see an "Attention Required" page when visiting a site?

You saw the page because Cloudflare detected a condition that required verification. The site you were trying to access is protected by Cloudflare and the request matched a rule or risk pattern that triggers a challenge; completing the browser checks confirms you are a legitimate visitor before the site is served.

When should I whitelist an IP to avoid the challenge?

Whitelist IPs when you have trusted machines that perform automated requests or partner services that cannot execute browser checks. Examples include API clients, monitoring probes and certain partner integrations; whitelist only known, stable IPs and use fine-grained rules to avoid creating security gaps.

Where can I see logs of challenges issued by Cloudflare?

Cloudflare provides challenge logs and analytics in the dashboard and via the audit logs API for paid tiers. The dashboard shows counts of blocked and challenged requests, firewall rule hits and WAF events; Enterprise customers can stream logs to SIEMs for real-time analysis via logpush or logpull.

What should I do if my API client is blocked by the challenge?

Use token-based authentication or IP-based exemptions to prevent API clients from being challenged. API clients should authenticate using API keys or tokens and be configured to use whitelisted IPs or bypass rules so that the interstitial challenge, which is browser-based, does not interfere with automated API traffic.

How do I troubleshoot users who cannot pass the challenge?

Start by checking browser settings: ensure JavaScript and cookies are enabled and that privacy extensions aren’t blocking scripts. Review Cloudflare’s challenge logs to identify the rule triggering the challenge, confirm whether the user’s IP or user agent is unusual, and temporarily relax rule sensitivity or whitelist the affected client while you investigate.
