Mixed deployment estate
One product may need to run in the vendor cloud, a customer VPC and a tightly controlled on-premises environment.

For financial software
A smaller trust boundary for high-consequence products.
Financial applications can keep authentication compact, auditable and deployable while their own systems remain responsible for portfolios, trades and entitlements.

The operating reality
A financial platform serving regulated organisations
The platform needs a consistent sign-in boundary across its standard SaaS deployment and private customer environments. RustyAuth authenticates users and issues narrowly scoped identity claims; the financial platform continues to own account relationships, suitability, permissions and every business decision.
High-consequence access
A stolen session can expose sensitive data or create a path towards valuable operations.
Audit expectations
Identity events need to feed the organisation’s wider evidence, monitoring and incident-response systems.
What the core contributes
Authentication stays small.
The product stays authoritative.
RustyAuth establishes who authenticated and issues narrow claims. Sector-specific systems keep every business decision.
Portable boundary
A small Rust service and private persistence topology.
Revocable access
Durable sessions and independently revocable service credentials.
Recovery operations
Encrypted logical backups with verification and clean-room restore commands.
Honest boundary
What this story does—and does not—claim.
Regulated infrastructure earns trust through evidence. These boundaries remain explicit in the 1.0.0 GA contract.

- Portfolio or trading permissions

- Business systems of record
Production profile requires
