      StrongKey Tellaro is a comprehensive software suite that provides strong authentication, encryption, tokenization, PKI management, and digital signature management. Our open-source software includes a FIDO® Certified FIDO2 server, and we support flexible data center and cloud deployment models.


      FIDO Strong Authentication

      StrongKey FIDO Server (SKFS) is FIDO2 and U2F certified and can be integrated with merchant websites, third-party payment services, and card issuer authentication systems to enable merchants to offer a frictionless checkout experience. With FIDO, merchant and issuers authenticate cardholders and banking customers with ease, avoiding cumbersome redirects and insecure one-time passcode 2FA methods. The Tellaro appliance uses hardware-based FIPS 140-2 Level 2 certified TPM by default and can be upgraded to a FIPS 140-2 Level 3 HSM, enabling you to meet the stringent requirements for PSD2 SCA, PCI DSS, and GDPR.

      Tokenization and Encryption

      Our Tokenization and Encryption software module enables companies to meet PCI DSS, GDPR, and CCPA requirements for data privacy. We utilize our application level-encryption and tokenization technology to protect personally identifiable information (PII) such as credit cards, account numbers, passwords, and other sensitive data. StrongKey has been providing PCI DSS solutions for more than 15 years. Combined with our FIDO Strong Authentication, we support Application Level Encryption and Strong Authentication (ALESA).

      PKI Management

      Our PKI Management software module provides secure key generation, key storage, certificate generation, an onboard root CA, and key and certificate lifecycle management. Our Tellaro appliance includes an HSM or TPM to support the highest levels of hardware-based authentication assurance. Integrated with in-house device provisioning and management systems, we allow financial providers to securely manage keys and digital certificates or devices, systems, applications, data and signing.
