Silicon:SAFE Password Protect

Silicon:SAFE Password Protect is a hardware authentication appliance designed to replace traditional password databases. It stores login credentials — including usernames, passwords, PINs, and answers to secret questions — directly in silicon, making it physically impossible to extract credential data remotely. The appliance operates on a "No-Read" principle: credentials can be written and verified, but never read back out. Authentication requests are submitted via HTTPS POST, and the appliance returns only a YES/NO verification result — no credential data ever leaves the device over a network connection. Key architectural properties: - No operating system, database, or conventional software stack, eliminating OS-level vulnerabilities - No execution of external programs, providing immunity to malware, buffer overflow, SQL injection, XSS, and code injection attacks - No administrator password or network-accessible backdoor - Data stored directly in silicon without reliance on encryption or key management The solution is available as a multi-tenant hosted managed service with appliances located in data centers across Europe, America, and Asia-Pacific. Each tenant operates within an isolated namespace. Appliances support clustering, load balancing, geographical failover, and high availability. Credential replication between appliances is used for backup, since passwords cannot be dumped to external media. Migration tools are provided to move existing credentials into the appliance without requiring password resets. Integration into existing authentication workflows requires replacing SQL-based credential lookups with HTTPS POST calls to the Password Protect service.
