The continuous-authority narrative is right. The enforcement still has to happen in your code.
SecureAuth’s Agentic Authority Platform made “authority must be continuous” the market’s thesis — runtime authorization at the API edge, agent detection, tamperproof audit, deploy-anywhere. But a control plane decides at the edge; the action still executes deep inside your application. B5 is the in-process Policy Enforcement Point that makes that decision binding at the method that moves money.
Framing: Use SecureAuth to decide & detect across the estate. Use B5 to enforce, in your .NET tier, inside your boundary.SecureAuth is the best teacher in this category — and the closest messaging comparator.
SecureAuth spent heavily to build a single, repeatable thesis: authority must be continuous, evaluated and enforced at every action, adjusted in real time as risk changes. That arc is correct, and B5 ladders to a sharper primitive for it — Never Trust. Where B5 differs is structural, not rhetorical: SecureAuth is a control plane your app, gateway, or sidecar must call out to and then honor; B5 is enforcement that lives where the action executes.
Borrow this, don’t fight it
- A single, repeatable continuous-authority thesis the whole market now repeats
- First-class agent identity stated plainly — unique credential per agent, bounded delegation, live attribution
- Agent Detection & Response (ADR) and tamperproof, exportable audit
- Deploy-anywhere including on-prem for regulated environments
- Audience-pillar IA with concrete failure stories and proof quotes
Call-out architecture: the edge said yes; your code still enforces
- The decision is made at the API edge or control plane — the action runs downstream in code the customer writes
- Enforcement of an agent’s scope still depends on hand-written checks at the method
- A new operated platform is a new live attack surface and a vendor-risk line item
- B5 compiles enforcement in: no edge-said-yes-but-the-code-forgot gap, no hot-path network hop
SecureAuth decides. B5 enforces — at the line of code.
| SecureAuth | B5 Secure | |
|---|---|---|
| Locus of enforcement | API edge / control plane; ADR at the access layer | In-process, at the call site |
| New live attack surface | Yes — operated platform | No added service or endpoint |
| Authorization data leaves your boundary | Traffic routes through the platform | No — evaluated in-process |
| New sub-processor for the customer | Yes | No |
| .NET integration | SDK / gateway, generic | Idiomatic [Permission] attributes & middleware |
| Agent identity model | First-class (detection-oriented) | First-class + in-process enforcement today; agent OBO + ephemeral scope is a Q4 2026 roadmap extension |
| Best role in your architecture | Decide & detect across the estate | Enforce the decision where it executes |
Capability status. 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.
The questions a buyer actually asks
We’re already evaluating SecureAuth’s Agentic Authority Platform.
Good — it decides and detects across your estate. The question is who enforces the decision at the method that moves money. Today that’s hand-written code. B5 makes it a declarative [Permission] attribute, evaluated in-process every call.
Doesn’t SecureAuth deploy on-prem too?
Yes — and they use it as a closing differentiator. B5 wins that argument outright: a library is the ultimate deploy-anywhere. There is no B5 endpoint to stand up, reach, or breach; the code runs where your code already runs.
Are you trying to replace SecureAuth?
No. B5 is the enforcement substrate for the .NET application tier — complementary to a Tier-1 platform. Overclaiming “rip out SecureAuth” isn’t credible or necessary. The decision layer is only as strong as its last enforcement point; that point is your code.
Complementary, not competitive.
SecureAuth across the estate; B5 at the .NET call site.
Let SecureAuth decide and detect across workforce, customer, and agent traffic. Let B5 enforce the resulting decision inside your .NET applications — designed to bind each agent’s On-Behalf-Of scope to the exact method it invokes (H2 2026), capturing the audit record at the execution point. Continuous authority is only as strong as its last enforcement point.
The platforms decide. B5 enforces — at the line of code where the action happens.
