Integrate MPAS Once. Run It Your Way.
SignerSet helps you embed the open-source MPAS SDK in your product or security stack. Use SignerSet Cloud APIs, deploy the MPAS infrastructure in your own environment, or combine the two.
Where MPAS sits
A decision point before credentialed execution
An agent or application proposes an exact request. The MPAS control layer coordinates the approvals required by policy and independently verifies their signatures. The credential boundary releases only the authorized action to the target system.
SignerSet complements gateways, PAM, IAM, policy engines, secrets managers, sandboxes, and observability. It does not replace them.
Choose how to run it
One integration. Your choice of infrastructure.
The MPAS integration stays portable across deployment models. Start with a managed service, operate the open-source infrastructure yourself, or divide responsibilities around your security boundaries.
SignerSet Cloud
Use managed APIs for proposals, approval coordination, signature verification, and authorization receipts. You define the policy and keep credentialed execution within the boundary you choose.
Self-hosted
Deploy MPAS-based APIs or an instance of SignerSet in your own cloud. You operate the infrastructure and retain control of keys, policy, approval data, credentials, and execution.
Hybrid
Use SignerSet Cloud for selected coordination services while keeping sensitive components in your environment. Choose the boundary component by component.
MPAS is a portable approvals protocol just like OAuth is a portable authorization protocol.
Integration support
Use the help you need. Keep the control you want.
