Agent authorization is not one-size-fits-all

OAP focuses on production enforcement: synchronous decisions before every tool call, versioned policy packs, and a path to regulated assurance. Use this lens to compare approaches fairly.

Two teams can solve “agent permissions” with different goals: cryptographic elegance, zero-infra bootstrap, or enterprise-grade policy and latency. The table below summarizes how OAP (APort) positions against common alternatives — without claiming others have no merit.

When you need delegated authorization at the tool boundary with signed decisions and kill switches, compare hooks and audit models — not slide decks.

Pre-action enforcement

Is every sensitive action gated before execution?

OAP / APort: Yes — `before_tool_call` / shell hooks; model cannot bypass the platform layer.
Prompts & alignment only: No deterministic gate — relies on the model following instructions.
Sandbox / container only: Contains blast radius; does not prove the action was authorized under policy.
Agent Passport System: Signed ActionIntent → PolicyDecision flow; depends on agent participation in the chain.

OAP emphasizes platform-level interception; sandboxes complement but do not replace authorization.

Policy as data

Named, versioned rules vs ad hoc checks

OAP / APort: Versioned policy packs (e.g. `system.command.execute.v1`, `mcp.tool.execute.v1`) with schemas and tests.
Prompts & alignment only: Implicit in prompts; changes require prompt edits and redeploy of behavior.
Sandbox / container only: Infrastructure policy (network, FS); not the same as per-capability business rules.
Agent Passport System: Delegation scopes and values floor; evolving toward OPA/Cedar-style evaluators.

Enterprise identity & assurance

Tiers that map to real-world trust

OAP / APort: Assurance levels L0–L4FIN (self-attested through KYC/financial-grade paths).
Prompts & alignment only: Not applicable.
Sandbox / container only: Not applicable.
Agent Passport System: Strong self-sovereign keys; less emphasis on tiered organizational assurance in v1.

Audit & proof

What can a third party verify?

OAP / APort: Signed decisions, passport digest, append-first audit logs; verifier integrates with registry.
Prompts & alignment only: Conversation logs only — no cryptographic authorization record per action.
Sandbox / container only: Runtime telemetry; not a substitute for per-decision proofs.
Agent Passport System: Merkle-linked receipts and three-signature chains — strong non-repudiation story.

OAP’s proof model is pragmatic for shipped guardrails; Agent Passport’s chain is strong where full agent cooperation holds.

Delegation between agents

Sub-agents and narrowed scopes

OAP / APort: Delegation formalism is a known gap on the roadmap; passport-level suspend is production-ready.
Prompts & alignment only: No standard delegation object.
Sandbox / container only: Isolation does not express delegation semantics.
Agent Passport System: First-class: `createDelegation` / `subDelegate` with depth and scope narrowing.

MCP & IDE scale

Where developers actually run agents today

OAP / APort: Shipped adapters: OpenClaw, Cursor, LangChain, CrewAI, n8n, etc.; MCP-aware packs.
Prompts & alignment only: Universal but non-enforcing.
Sandbox / container only: Depends on deployment; not MCP-specific.
Agent Passport System: No dedicated MCP server in v1.1; TypeScript-first evaluator.

Latency posture

Typical evaluation path

OAP / APort: Hosted API ~53–65 ms median in published benchmarks; local evaluation supported.
Prompts & alignment only: Zero added latency; also zero enforcement guarantee.
Sandbox / container only: VM/container overhead only.
Agent Passport System: In-memory TS; public benchmarks TBD vs OAP’s published numbers.

Product & platform comparisons

Detailed APort vs pages for vendors, sandboxes, eval tools, and research systems — in addition to the approach-level matrix above.

When OAP is the right default

You run agents in real IDEs and frameworks, need SOX/SOC2-friendly audit, and want policy changes without retraining models.

When to combine

Use sandboxes for containment, model alignment for UX, and OAP (or another authorization layer) for allow/deny at the tool boundary — they are complementary, not competing substitutes.

Open specification

OAP is documented as an open spec with conformance artifacts. Competitors and partners can implement the same decision contract — APort ships the reference guardrails.
