Enforce Access At The API Layer.
Fine-grained authorization on every API call, based on identity, resource, context, and entitlement. Move beyond perimeter security to zero-trust API access control.
Broken Object-level Authorization Is The Top API Security Risk
OWASP's top API security risk is API1:2023 — broken object level authorization. Developers scatter authorization logic across microservices, creating inconsistencies. Broad OAuth scopes give applications access to far more than they need. Static API keys don't expire, rotate, or carry identity context. When a service is compromised, there's no boundary on what it can access.
Centralized Policy, Enforced At Every API Call
SecureAuth enforces authentication and policy-based authorization for every API call, including token validation, sender-constrained tokens, and fine-grained scope enforcement. Authorization decisions are centralized, auditable, and consistent across your entire API surface — not scattered across individual services.
Where API authorization matters
Real Environments SecureAuth Is Built For
APIs are the backbone of modern architecture — microservices, partner integrations, AI agents, and financial transactions all depend on secure, identity-aware API access control. These are the scenarios where generic token validation falls short.
Scoped tokens at every service boundary
In a microservice mesh, broad OAuth scopes give each service access to far more than it needs. If one service is compromised, the blast radius is the entire API surface. Static API keys with no identity context make it impossible to trace who authorized a call.
SecureAuth approach
Token exchange (RFC 8693) propagates narrowly scoped user context across service boundaries. Each service receives a token scoped to exactly its required resources. No service can access more than its defined scope, even if compromised.
Controlled API access for external partners
Third-party integrations need API access, but static API keys don't expire, rotate, or carry identity context. When a partner relationship ends, manually hunting for their keys across services creates a security gap.
SecureAuth approach
Issue scoped, short-lived tokens to third-party integrations with automatic expiry. Revoke instantly when the relationship ends. Full audit trail of every API call, tied to the partner identity, not an anonymous key.
Identity-aware API access for autonomous agents
AI agents calling APIs on behalf of users typically use over-broad credentials with no way to constrain them to the delegating user's permissions. If an agent misbehaves, there's no boundary on what it can access or audit trail of what it did.
SecureAuth approach
Each AI agent gets a resource-scoped token representing the user it acts for. Token exchange ensures agents can only call APIs within the delegating user's entitlements. Every call logged with agent ID, user ID, and resource accessed.
Sender-constrained tokens for high-value transactions
Payment processing APIs handle high-value transactions where a stolen bearer token could authorize fraudulent payments. Standard OAuth tokens can be replayed from any client if intercepted.
SecureAuth approach
DPoP sender-constrained tokens bind each token to the requesting client's cryptographic key. A stolen token is unusable without the corresponding private key. mTLS client certificate binding provides the highest assurance for regulated payment APIs.
Token capabilities
Every API Call Carries Identity, Scope, And Proof.
API authorization isn't just token validation. SecureAuth gives every API call fine-grained identity context, resource scoping, and sender-constrained proof — so authorization decisions are precise, auditable, and enforceable at the gateway, mesh, or service level.
Structured JWT with fine-grained claims
Resource URI, action, and context encoded directly in the token. Resource servers make authorization decisions without additional lookups.
Rich Authorization Requests (RFC 9396)
Fine-grained permissions specified in the authorization request itself. Move beyond coarse OAuth scopes to resource-level, action-level authorization.
DPoP sender-constrained tokens
Token bound to the requesting client's proof-of-possession key. Even if a token is intercepted, it cannot be replayed from a different client.
Centralized policy management
One place to define, version, and audit all API authorization policies. No more authorization logic scattered across individual microservices.
Automated API key rotation
Zero-downtime key rotation with overlap periods. Keys tied to service identity, usage monitored per key, anomaly detection on API key activity.

“We had 200 microservices all using broad service accounts. After implementing SecureAuth API Authorization, every service gets a narrowly scoped token with user context. Our blast radius from a compromised service went from ‘everything’ to ‘nothing beyond its scope.’”
