All the way down to the data.
B5 is the enforcement layer that ties identity to data — fail-closed, per operation, down to the data element. The layer your IdP, gateway, and vault don’t cover.
Breaches don’t stop at the perimeter.
Authentication is solved. The breach has moved to a question your stack can’t answer: can this caller touch this record?
Edge sees traffic, not records
Gateways, WAF and CDN filter requests at the perimeter — they can’t decide who may touch which record inside the app.
Identity ≠ authorization
An IdP proves who you are. It doesn’t enforce, per operation, what you may do to a specific row of data.
Over-broad access & plaintext sprawl
Past the door, apps over-return data and leak cleartext into logs and analytics. The damage is at the data layer.
The same authenticated request — two outcomes.
Identity proves who. What happens next — at the record — is the whole difference.
- ✗ Reads records it shouldn’t — OWASP API #1 (BOLA)
- ✗ Sensitive data returned in the clear
- ✗ A stolen token replays from anywhere
- ✓ Permit this record — or a fail-closed denial
- ✓ Plaintext only on the decision, scoped to fields
- ✓ Every decision audited, per data element
One pipeline: authenticate, then authorize per data element.
Every request runs the full gauntlet. The deepest layer — ADA — decides access on the data itself, fail-closed.
Screen
Input & XSS screening before anything is trusted.
Authenticate
Signed request — integrity, replay & expiry.
Gate
Adaptive IP firewall + MFA / step-up by risk.
Verify
Verification & rules-based suspension, mid-session.
Authorize
ADA — the operation AND the exact record. Fail-closed.
Decision-gated detokenization — plaintext only on a yes.
B5 doesn’t just decide — it gates the data. Sensitive fields stay tokenized until the data-element decision says reveal.
for THIS record?
The agent AND-gate — both must allow.
An over-permissioned agent still can’t exceed the user; a broad user can’t be used beyond the agent’s scope. Permit only if both allow it — per data element, fail-closed.
Agent
tools & scopes granted to the agent
User
records the user is entitled to
The security spine behind a $15B+ platform.
B5 modernizes a model already proven on a regulated fintech platform — the same data-element authorization, reimagined and rebuilt for .NET 10 and the agent era.
The open standards your team already trusts.
B5 implements them — and enforces them at the record. No proprietary crypto, no lock-in.
Everyone works upstream. B5 enforces at the record.
Authenticate, decide, vault — all happen before your code runs, in someone else’s service. B5 is the only enforcement point inside the app.
Decide & vault — OpenFGA · Oso · CyberArk · Skyflow
All necessary — none of them enforces inside your app, on the specific record.
Secure the layer that matters.
