OpenBait Founder / Principal Engineer

Authentication infrastructure engineer at Japanese listed companies (10 yrs)

Ten years running authentication infrastructure — OIDC / SAML SSO, Passkey / FIDO2, DMARC / DKIM / SPF / BIMI — at Japanese listed companies. Daily contact with phishing attacks against those same systems made it clear that the mid-market gap in brand-protection tooling wasn't going to be closed by the existing players.

OpenBait exists to be the platform that bridges typosquat detection, brand impersonation monitoring, and registrar/browser-level takedown for mid-market companies that don't have the budget to run four separate vendors.
