AI companies are scraping your site.
You decide who profits from it.
Centinel detects and blocks AI crawlers in real time. Stop unauthorized scraping before it costs you revenue, content, and competitive advantage.
Online newspapers & digital magazines
AI companies scrape your articles, bypass your paywall, and train models on your journalism — without paying a cent.
Built for how publishing teams actually work
Four capabilities designed around editorial workflows — from paywall-aware detection to licensing revenue, without adding infra for your team to maintain.
Paywall bypass protection
Catch crawlers that slip past your paywall by impersonating real subscribers.
Licensing revenue from AI access
Set your terms. Charge AI companies per request for access to your archive.
Editorial traffic stays clean
Human readers and verified search bots always pass through. No disruption.
No IT team needed
One snippet, five minutes. Works with WordPress, Drupal, Ghost, and major CDNs.
Know who's accessing your content. Act on it.
Articles, product data, pricing feeds, catalogues. Whatever you publish, Centinel shows you who's taking it and gives you the controls to respond.
Identifies 1,600+ AI crawlers
Fingerprints every request against our crawler database. Catches bots hiding behind residential proxies, headless browsers, and spoofed user agents.
Block in under 2ms
Edge-level enforcement before the request reaches your origin. Real readers and verified search bots pass through untouched.

Turn scraping into revenue
Set per-request licensing fees. GPTBot, ClaudeBot, PerplexityBot — charge each one differently, or block them outright.
See exactly who takes what
Dashboard shows which companies crawl you, how many requests per day, what content they target, and what it costs you in bandwidth.
Live in three steps. No IT ticket needed.
Most customers are fully protected the same day they sign up.
Add the browser script
A lightweight script loads on protected pages and sets a session cookie. Pre-built for Cloudflare Workers, CloudFront, Fastly, Akamai, Nginx, WordPress, Drupal, Next.js, and 8 more.
We validate every request
Your infrastructure calls our validation API. In under 2ms, Centinel returns a decision: allow, block, or challenge, with full crawler metadata.
You control the outcome
Block a crawler, add it to a watchlist, allow it, or set a licensing fee. Your dashboard shows who's crawling, how often, and in what category.
Charge AI companies for the data they already take
Other platforms just block scrapers. Centinel lets you decide: block what you don't want, and charge for what you're willing to license.
Your content is worth money. Price it.
AI companies need high-quality data to build their products. Centinel shows you who's taking yours and gives you the tools to set a price. Define your terms. The platform handles the rest.
What companies ask before signing up
We already use Cloudflare — why do we need Centinel?
Cloudflare uses static IP-based rules and generic WAF signatures. Sophisticated AI crawlers bypass them easily. Centinel uses behavioral fingerprinting tuned specifically to content scrapers, combining a browser script with server-side validation to detect new agents within hours.
Will it block real users or search engines?
No. Centinel distinguishes between automated bots and human visitors with high accuracy. Verified crawlers like Googlebot are automatically allowlisted.
How does the integration work?
A lightweight browser script sets a tracking cookie on protected pages. Your infrastructure calls our validation API for real-time decisions. Pre-built integrations for 16+ platforms including Cloudflare Workers, CloudFront, Fastly, WordPress, and more.
Does it work for industries beyond publishing?
Yes. Centinel protects any site with high-value data — retail, travel, finance, streaming.
What decisions can I make per crawler?
Allow, block, watchlist, or set a licensing fee. The dashboard shows real-time metadata including company, category, and access frequency.
Can we trial it before committing?
Yes — we offer up to 6-month discounted pilots for qualifying companies.
