A visible promise
When someone sees the badge, they know this sign-up is defended — that a real check stands between them and the bots, spam, and abuse that flood unprotected forms.
Crossdeck Trust
The sign-up you just made was verified by a human check — not a CAPTCHA.
No puzzles, no fire hydrants, no traffic lights. A silent proof ran in the background while you typed — and it told this app you're a real person, not a script.
What it is
A verification step that runs in a blink.
Behind an ordinary form, your browser quietly earns a signed proof-of-human token — a short-lived cryptographic receipt that a real browser can produce and a scripted bot can't. When you submit, that token rides along. No token, or a token a machine forged, and the app knows to look closer. You never saw a challenge because there wasn't one to solve.
How it protects
Four steps, start to finish.
Every sign-up runs the same path — from the silent check to the moment a human decides what happens next.
-
01
Verify
The browser earns a signed proof-of-human token before the form is ever submitted — invisibly, in the time it takes to type.
-
02
Score
Crossdeck weighs the whole journey — the token, the path, the signals — into a single trust score. Not one request in isolation, the story around it.
-
03
Surface
Anything that looks off is surfaced to you in plain sight — the suspicious sign-ups, the IPs, the domains — ranked, so you see what matters first.
-
04
Block
You decide. Add an IP or a domain to your blocklist and Crossdeck enforces it at every door — sign-up and log-in — from then on. Blocked once, they can't create an account and they can't sign back in. Any pages they've already published come down too.
The badge
“Protected by Crossdeck Trust” is a promise your users can see.
The mark on the form isn't decoration. It stands for three things.
No vendor lock-in
Crossdeck Trust is native to Crossdeck. There's no third-party CAPTCHA to embed, no external puzzle service, no rented widget on the critical path of your own product.
It scores the journey
Trust judges the whole path a person took to arrive — not a single request in a vacuum. That's how it tells a genuine new customer from a script wearing one.
You just passed the check. That's the whole point.
Crossdeck Trust is built into every Crossdeck workspace — verifying real people, scoring the journey, and leaving the final call to you.
Trust, in production
Digital Hank runs Trust on its signup door. Their write-up covers the part that is easy to get backwards — the absence of an attestation is the signal, and the gate is fail-open rather than fail-allow, so an adblocker or an outage cannot turn a real customer away.
