Any vault can store a credential. Ouroboros rotates it across your entire fleet. It dual-writes, health-checks, drains live connections, and rolls back automatically the instant anything looks wrong.
$ ouro rotate --secret app/db rotating vault:app/db IDLE → ROTATION_TRIGGERED ok ROTATION_TRIGGERED → NEW_SECRET_ISSUED ok NEW_SECRET_ISSUED → DUAL_WRITE_ACTIVE ok DUAL_WRITE_ACTIVE → HEALTH_CHECK_NEW ok HEALTH_CHECK_NEW → CUTOVER ok CUTOVER → DRAIN_OLD ok DRAIN_OLD → REVOKE_OLD ok REVOKE_OLD → IDLE ok done. old credential retired, 0 dropped connections.
A single database password can be used by a dozen microservices. Rotate it carelessly and you strand half of them on a dead secret. So teams don't rotate, and stale, over-permissioned credentials pile up until one leaks.
Ouroboros runs as a sidecar next to your workload. It issues the new credential, keeps the old one valid during a dual-write window, and only cuts over once the new one passes a real health check. If anything fails before cutover, it rolls back. The old secret is never revoked until the new one is proven live.
Old and new credentials are both valid while consumers pick up the change. The window is configurable per secret.
Per-protocol tracking of DB connections, in-flight HTTP, and SSH sessions, so the old secret is retired only when nothing is using it.
Any failed health check reverts instantly. Crash-safe checkpoints mean a restarted sidecar resumes, never strands.
Any single sidecar can rotate a secret. Ouroboros coordinates a whole fleet. A control plane tracks which services consume which secret and only completes cutover once every dependent confirms healthy on the new value.
Declarative map of secret → consuming services. A shared credential rotation never leaves a service behind.
Canary one consumer, then fan out. Configurable blast radius keeps a bad rotation contained.
Production rotations can require a human approval step, enforced by policy, per environment.
Auto-rotate on exposure signals. A secret found in a public repo scan kicks off rotation immediately.
Every state transition, actor, and timestamp, exportable to CloudWatch, Splunk, or S3 for compliance retention.
Prometheus metrics on every sidecar and a shipped Grafana dashboard. Alerts to PagerDuty, Slack, Opsgenie.
Hybrid and multi-cloud from day one, because the teams with real infrastructure complexity are exactly the ones that need this.
Usage-based on the number of actively-managed secrets, with no per-seat friction. Available on the AWS Marketplace with native billing.
For teams proving out rotation.
Fleet orchestration for production.
For regulated, multi-cloud estates.
The single-sidecar rotation engine is open source under Apache-2.0, so you can inspect it, run it, and trust it. The fleet-orchestration control plane is the commercial layer. Written in memory-safe Go, with a full, exportable audit trail of every rotation.
