Bot and AI crawler protection for websites and apps
Centinel verifies search and AI crawlers and detects scrapers that run real browsers behind residential proxies. Your access policy then blocks the scrapers and keeps the crawlers you rely on.

Where automated traffic costs you
Bots copy content, take over accounts, and hit APIs directly. Each route needs different evidence and a different response.
All use casesScraping & AI crawlers
Protect content, catalogs, and application data without blocking every crawler. Start by checking which scraping tools can retrieve your pages, then choose controls that preserve approved access.

Credential-stuffing tools can replay exposed username and password pairs at scale. The login still needs its normal authentication and account-security controls.
Learn moreAPI abuse
Mobile apps, partner integrations, and backend services may call an API without loading a page. Those requests need a policy built from the evidence the server integration actually receives.

Bot protection by industry
An article archive, a product drop, and a ticket on-sale attract different bots. See what yours faces.
All industriesTell real visitors from scrapers that look like them
A crawler can run a real browser and resemble an ordinary visitor. Centinel evaluates the request, the browser, and the connection together instead of treating one signal as a verdict.
How the layers fit togetherDeclared crawlers
Verify known identities and set policy per crawler.
Basic scripted clients
Identify request automation that does not behave like a browser.
Browser automation tools
Detect spoofed browsers and commercial scraping APIs running at scale.
It runs in the stack you already have.
Your edge asks Centinel to check the request before serving the page. Keep your existing CDN, reverse proxy, or application in place.

Common questions
What site owners ask before deployment.
How is this different from our CDN or WAF?
Your CDN and WAF stay in place. Centinel adds crawler verification and browser-side evidence for automation that looks like ordinary visitor traffic. Check what your current setup already detects on the routes that matter, then test whether Centinel's evidence changes a decision on the traffic it misses.
What did the September 2026 benchmark test?
We ran eight scraping and browser-automation tools (Browser-use, Firecrawl, Browserbase, kernel.sh, Playwright Stealth, Camoufox, Zyte, and Ulixee Hero) against Centinel, Akamai, Cloudflare, DataDome, Fastly, HUMAN Security, and Kasada, and recorded whether each product detected each tool. The results are our observations from the configurations we tested. Plans and settings differ, so test your own routes and traffic before you choose.
Why is browser-side verification necessary?
Browser-like headers alone do not explain who controls a visit. Where browser collection is supported, runtime and session evidence adds context to the request. Evaluate that evidence with the protected workflow and your access policy.
Will visitors see a CAPTCHA?
Centinel's browser checks run automatically. The response a visitor receives depends on the integration and policy, so test challenge behavior, accessibility, and session continuity during your evaluation.
Can we allow trusted crawlers while blocking scrapers?
Yes. Centinel separates declared and verified crawlers from spoofed or hidden automation, so your team can apply a different access policy to each traffic class.
Is Centinel GDPR-compliant?
Yes. Centinel minimizes personal data and uses request and browser signals only to separate automated traffic from genuine visitors.
