Native workload identity
Accept cloud identity evidence, Kubernetes service account tokens, SPIFFE SVIDs, and client certificates through the appropriate authentication mechanism.
Machine access infrastructure for B2B SaaSBring your workload identity.
Bring your workload identity.
Control everything after.
Federate AWS, Azure, GCP, Kubernetes, SPIFFE, and X.509 identities into tenant-scoped SaaS access. Give your enterprise customers self-service policy controls and audit trails—without building an identity platform.

The platform
Identity is only the beginning.
Your customers need to authenticate their workloads, restrict their access, and prove what happened. Workbound connects all three.
Customer-controlled access
Allow customers to register workloads, narrow scopes, restrict token issuance by IP range, and disable trust relationships—within vendor-defined limits.
Two views of every event
Give customers visibility into their own workload activity and vendors a cross-tenant operational view, with redaction and export controls.
Developers / Identity acquisition
Start with real workload credentials.
No pretend universal OIDC assertion. These examples show how each runtime obtains or presents identity evidence before Workbound exchanges it.
Developers / SaaS integration
One control plane. A thin data plane.
Register customer trust through an administrative API. Validate issued access tokens locally in your API. Optionally send resource-access events for richer audit trails.
Proposed Workbound APIs and SDKs; code illustrates the intended contract rather than a released implementation.
Architecture
Federation is our job.
Authorization stays yours.
01 / CUSTOMER
Workload or agent
AWS · Azure · GCP · Kubernetes · SPIFFE · mTLS · MCP client · A2A agent
02 / WORKBOUND
Exchange data plane
Validate native identity evidence, apply tenant trust policies, issue short-lived audience-bound access tokens.
03 / VENDOR
SaaS API / MCP server
Verify token signature, audience, organization and scopes. Enforce resource-level authorization.
identity proof → policy-constrained exchange → API authorization
CONTROL PLANE
Customer self-service · Trust registration · Policy · Audit
Vendor-defined maximum permissions, customer-managed restrictions, and separate tenant and vendor audit views.
Local JWT validation avoids a Workbound call on every API request. Immediate revocation, request-time IP restrictions, and proof-of-possession require additional resource-side enforcement.
Governance
Enterprise controls your customers can own.
Bounded by both parties
Vendors define maximum scopes, audiences and token lifetimes. Customers can further restrict workload identities, networks and permissions.
Visibility without credential exposure
Capture exchanges, denials, configuration changes, and optionally API usage. Partition events by customer and provide a vendor-wide operational view.
MCP and agent-to-agent access
Authenticate an agent's workload identity. Preserve separate, verifiable user delegation when an agent acts on someone's behalf.
Explicit trust boundaries
Short-lived tokens, signed access claims, audience isolation, policy versions, and optional sender-constrained access.
