Most apps don’t fail because of bad auth - they fail because access logic is scattered across APIs, databases, and microservices. Seal, part of the Sui Stack, fixes that. It enforces access where it matters most: at the data layer. Programmable. Auditable. Portable.

Web2 Cloud IAM solves infra questions like “can this identity call this API?” But products care about “can this user open this object, under these conditions, right now?” Seal solves that gap - access that understands data, context, and timing.

Seal flips the model: - Data stays encrypted by default - Decryption only happens when a policy explicitly allows it - The policy travels with the data Encryption is the gate. Policy is the key.

Because policies live with data, you can express business logic cleanly: - Gold-tier users can open gold/* - Decrypt after 2025-11-01T00:00Z - Only NFT holders can unlock perks Different rules, same model - no external rule engines or tangled RBAC layers.

Running on the Sui Stack, Seal makes access programmable and verifiable: - Sui anchors policies and approvals on-chain - Walrus stores encrypted data and audit logs - Nautilus handles distributed key checks for scalable hybrid apps End-to-end privacy that’s composable by design.

Instead of juggling three control planes - IAM, service auth, and data permissions - Seal enforces access at the data boundary. If the policy doesn’t approve, the data never decrypts. Fewer moving parts. Smaller blast radius.

Seal makes access a primitive, not an afterthought. Built for developers building real products - with Sui’s fast, object-based architecture and composable storage through Walrus. Access control, rebuilt for data.
