Your data is yours. Structurally, not contractually.
TPS Cal is built for shops whose customers include aerospace and defense primes. The security model is designed to be answered for — the way a quality manager or a customer security questionnaire will actually ask.
ISOLATIONDatabase-per-customer
TRANSPORTTLS 1.2+ everywhere
ACCESSRole-based, token-authenticated
IsolationEvery customer's data lives in its own database — not a shared table with a customer column. Cross-tenant access isn't a permissions rule that could fail; it's a boundary that doesn't exist.
TransportAll traffic is TLS-encrypted end to end, with modern cipher configuration and HSTS enforced.
AuthenticationShort-lived token authentication with rotation; role-based access separates technicians, office staff, and administrators.
BackupsEach customer is backed up independently — separate files, separate restore, separate deletion on offboarding — with offsite copies retained long-term.
Audit trailCompliance records carry full change history, and administrative access is rate-limited and logged.
DeletionWhen a customer leaves, their data can be destroyed completely and provably — including backups, because backups are per-customer files, not one commingled archive.
