Verified Browser Trust

Trust the browser before you trust the action

Peakhour verifies that the browser ran the issued challenge before high-risk logins, account changes, checkout actions, or browser-backed API calls continue. It gives the risk decision a stronger browser signal without forcing trusted users through visible CAPTCHA friction.

Request shape alone should not decide account trust

Sophisticated automation can reuse headers, cookies, browser claims, and proxy-backed sessions. For sensitive actions, teams need to know whether the browser ran the challenge Peakhour issued for that request.

Header and cookie replay

Automation can copy the outer shape of a browser request without running the browser code behind it.

Login and account actions need higher confidence

A password match or valid session can still be risky before resets, profile changes, saved-card use, or checkout.

Browser trust must be reviewable

Fraud and security teams need to see challenge issued, witness returned, validation result, and policy action in one record.

Make browser trust part of the action decision

Peakhour ties each challenge to a fresh VM blueprint. The browser runs selected challenge slices and returns a witness. The server checks that evidence against the issued challenge before choosing the least disruptive action.

  • Per-request VM blueprint

    Generate challenge-specific execution material instead of relying on a static JavaScript token.

  • Browser trust witness

    Collect digest and trace evidence from the browser challenge path.

  • Strict replay checks

    Validate enforceable slices against the server's expected challenge flow.

  • Policy action

    Use valid, missing, malformed, or mismatched witnesses as signals for allow, challenge, throttle, block, or review.

Browser trust stays attached to the decision record

Verified browser trust is strongest when it stays attached to the route, session, account event, policy version, and final action. That record gives fraud and security teams a concrete signal to review without pretending the witness proves everything by itself.

Issue Challenge material Fresh VM blueprint and slices
Execute Browser returns witness Digest and trace evidence
Verify Replay check Expected challenge path matched
Act Policy decision Allow, challenge, throttle, block, review
Headers and cookies are no longer the only browser evidence Request shape
Witness status joins credential, proxy, device, behaviour, and route context Risk decision
Challenge, witness, validation, and action stay queryable Review trail

Security teams can separate clients that ran the challenge from scripts that only replay request shape, then choose the least disruptive action that fits the rest of the risk context.

It proves

The issued challenge path produced matching evidence.

  • The client returned evidence from the Peakhour challenge path.
  • The witness matches the issued challenge material and expected execution slices.
  • The result can be attached to a request, route, session, account action, and policy decision.

It does not prove by itself

The user, device, and account are automatically trustworthy.

  • The user is human.
  • The device is trustworthy.
  • The account owner is legitimate.
  • The request should be allowed without credential, proxy, device, behaviour, and route context.

Protected journeys where browser trust matters

Risky sign-in

Require a verified browser signal before accepting suspicious logins or deciding step-up friction.

Account state changes

Add witness evidence before password reset, email change, saved address, stored payment, gift-card, or checkout actions.

Browser-backed API actions

Attach browser trust evidence to token, cart, account, and verification API calls that originate from browser sessions.

Fraud and support review

Export challenge and witness outcomes with the rest of the request evidence.

Verified browser trust does not replace authentication, fraud review, or device context. It gives the risk engine one sharper fact: did this browser return valid evidence from the challenge we issued?

Add verified browser trust before protected actions

Map the login, account, checkout, and browser-backed API actions where replayed request shape is not enough. Peakhour can add browser trust evidence before those actions complete.
