Don't leave your customers guessing.
Give them Proofmarked and own the trust you've earned.

Off-the-shelf attack kits made impersonation a commodity, turning the web into a Market for Lemons where cheap deception creates universal uncertainty. Proofmarked shifts the burden off your users—converting legal trademark ownership into an unforgeable visual signal that excludes impersonation by design.

Post-Scam Attrition Rate
30%
CMO & Head of Digital Banking

30% of scam victims switch banks afterward — attrition you didn't cause and now have to explain.

The verified mark shows up exactly where hesitation costs you conversion — login, transfer, reset — and unlike a compliance banner, it's something you can actually test.

  • Fewer scam-driven account closures reaching your retention number
  • A measurable lift on your highest-hesitation pages
  • One less unowned element inside a journey your team is measured on
Impersonation Attacks
60%
Head of Fraud & Trust and Safety

6 in 10 scams start with someone impersonating a trusted actor — often you.

Every domain your bank owns is authorized explicitly, so a reported lookalike gets pulled from resolvers and safe-browsing feeds in minutes instead of chased down by hand for weeks.

  • Fewer impersonation-driven cases reaching the loss reserve
  • Analyst hours reclaimed from manual takedown work
  • Protection that extends past your own user base
Unmonitored Domain Gaps
0
CISO & Risk Officers

Every lookalike domain using your name is an incident your team verifies by hand and waits weeks to close.

You hold a signed authorization record for every domain you approve, feeding straight into an automated takedown pipeline instead of a manual registrar request.

  • Minutes-not-weeks takedown on confirmed impersonation
  • Fewer manual verification cycles pulled onto the SOC
  • A board-reportable number, not just a compliance checkbox

How it works

Just because the internet is stateless, it doesn't have to be lawless.

Proofmarked operates as a B2B2C SaaS platform that goes beyond domains and SSL/TLS certificates to make it clear if a URL has been authenticated & authorized by the organization the user intended to interact with, or not.
