What makes us help you
Why TrustSEC
Hardware-rooted, from the fingerprint to the chip.

01 / THE PROBLEM
A shared password is a door your auditor cannot close.
Every shared secret is an identity your logs cannot resolve to a person. Passwords and one-time codes leave staff exposed to phishing, credential theft and account takeover — and an assessor looks for that gap first.
A card that holds its own key, and a fingerprint that never leaves it, close the gap by making the credential physically unshareable.
Solutions
Four doors, depending on what you need to protect.
Authentication, identification, payment and mobile-app protection — every one built on the same in-house operating system.
Authentication
FIDO2, PKI, access control and OTP — hardware-rooted, with the fingerprint matched on the card.

Protection for applications that run on devices you do not control.
THE GUARDIAN · ELSIntegrations
One card. Every system that has to trust it.
SLCOS runs several applications side by side in one secure element, separated by GlobalPlatform security domains — so one credential can serve each system below.
Applets are deployed across multiple chip platforms without modification, and SLCOS integrates with multiple biometric sensor and module vendors — protecting the investment and simplifying migration.
