The majority of your traffic isn’t people.
The “dead internet” stopped being a theory. Bots crossed 50% of all web traffic, AI agents are the fastest-growing client on the web, and every free tier is an open faucet.
Why this costs you money.
If your product runs a generation, grants free credits, mints API keys or sends email on signup, every automated “user” converts directly into cost. Bot abuse isn’t a security line item anymore — it’s a unit-economics problem.
And the abusers aren’t script kiddies: they’re agents that render pages, execute JavaScript, and solve every puzzle you can buy.
Why behavior, not puzzles.
Puzzles test what a client can solve. Behavior reveals what a client is. Cadence, integrity and coherence are produced as a side-effect of being a real person in a real browser — expensive to fake at scale, free for humans to produce.
That’s the bet HumanProof makes — deterministically, without an LLM, and without reading a single keystroke.
