VisitEstuary vs Sequin
What both publish
| Fact | Estuary | Sequin |
|---|---|---|
| Delivery | Estuary describes exactly-once data delivery with sub-100ms end-to-end latency. | The product describes 100% delivery with automatic retries, strict ordering, and exactly-once processing using idempotency keys. |
| Deployment | Deployment choices include shared public infrastructure, dedicated private data planes and bring-your-own-cloud environments. | Sequin runs as a Docker image alongside Postgres and uses Postgres to store sink state. |
| Security | Official documentation states encryption in transit and at rest, immutable infrastructure, a zero-trust network model and role-based access control. | The security page describes encryption standards supporting NIST-approved protocols such as TLS and says customers will be notified of incidents without undue delay, and where feasible within 72 hours. |
