Online newspapers & digital magazines

AI companies scrape your articles, bypass your paywall, and train models on your journalism — without paying a cent.

33:1
Perplexity's crawl-to-referral ratio on news sites
60%
of publisher traffic is bots, not human readers

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.

01

Paywall bypass protection

Catch crawlers that slip past your paywall by impersonating real subscribers.

02

Licensing revenue from AI access

Set your terms. Charge AI companies per request for access to your archive.

03

Editorial traffic stays clean

Human readers and verified search bots always pass through. No disruption.

04

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.

03Control

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.
