Where every platform ends — and in-code enforcement begins.
Control planes decide. External engines model. Vaults hold the credential. B5 Secure is the in-process Policy Enforcement Point that makes the decision binding at the .NET method where the action runs. Seven honest, complementary comparisons.
Everyone works upstream. B5 enforces at the record.
Identity providers authenticate, external services and gateways decide, vaults protect the credential — all before your code runs. B5 is the one layer that enforces in-process, at the .NET method, on the specific record.
One matrix, every comparison.
| Platform | What it is | Where it enforces | In-process, at the record? | Adds an operated service? | Best paired role |
|---|---|---|---|---|---|
| B5 Secure | In-process .NET PEP + data-aware PDP (ADA) | At the .NET method · per data element | Yes | No | The enforcement layer itself |
| Okta + FGA | IdP + externalized fine-grained authz | Edge (IdP) + external store | No | Yes | Authenticate & model decisions |
| Auth0 + FGA | CIAM front door + externalized authz | Edge (login) + external store | No | Yes | Login & onboarding |
| Ping Identity | IdP + agent gateway (Identity for AI) | Runtime gateway between agents & services | No | Yes | Broker & detect agent traffic |
| SecureAuth | Agentic Authority Platform | API edge / control plane | No | Yes | Decide & detect across the estate |
| OpenFGA | OSS Zanzibar/ReBAC service | External service / tuple store | No | Varies (self-host) | Model relationships |
| Oso | Authz library + Oso Cloud | Embedded or external (Cloud) | No | Varies (Cloud) | Model decisions |
| CyberArk | Privileged access mgmt & secrets | Credential vault / session broker | No | Yes | Vault secrets & broker access |
Capability status. B5’s in-process [Permission] enforcement Generally Available Agent OBO delegation, ephemeral SPIFFE-compatible agent identity and CAEP/SSF signal ingestion are Q4 2026 roadmap extensions Preview. Competitor capabilities reflect each vendor’s published materials; “varies” denotes managed vs. self-hosted deployment.
B5 Secure vs SecureAuth
Continuous-authority narrative, control-plane architecture. They decide & detect; B5 enforces at the call site.
Read the comparison →B5 Secure vs Ping Identity
A runtime agent gateway one hop in front of services. B5 enforces inside the .NET app, no gateway to operate.
Read the comparison →B5 Secure vs Okta + Okta FGA
IdP plus externalized FGA. B5 enforces each action in-process, with no tuple store to sync.
Read the comparison →B5 Secure vs Auth0
The best developer front door. B5 governs what every caller — human or agent — may actually do behind it.
Read the comparison →B5 Secure vs OpenFGA
Zanzibar ReBAC with an external tuple store. B5 keeps the decoupled-policy benefit, drops the store and the hop.
Read the comparison →B5 Secure vs Oso
First-class authorization via Polar / Oso Cloud. B5 delivers it as idiomatic .NET attributes — no new language.
