We used to beat bot protection.
Now we build it.
Centinel is a small team of reverse engineers and bot developers based in Berlin. Before we switched sides, we spent years building the crawlers that publishers were trying to stop. That's the whole reason we exist: we got tired of watching detection fail against tools like the ones we used to build, and decided to build the side that finally holds.
The people building your defense spent years breaking everyone else's.

Detection has to move faster than the attacker
Passive checks lose. A rule you write today gets solved tomorrow. Real protection has to hunt new scraping tools before they reach you, and change faster than anyone can adapt to it.
Below the JavaScript layer
Stealth crawlers pass every browser check. We fingerprint them one layer down, at TCP and TLS, where a real browser and a disguised bot stop looking alike.
We run every scraper ourselves
We buy and operate the stealth tools attackers use, then build detection from exactly where they break.
Dynamic by design
Static defenses get solved. Ours keep changing, so attackers never settle on a bypass that works twice.
Innovation raises the cost
Every update makes getting past us more expensive. The goal is to make scraping cost more than the content is worth.
Come build publisher-first bot protection
We're a small team working on a hard problem: catching the crawlers that look human. If that sounds like your kind of problem, we'd like to hear from you.
