Comparison

PermitNetworks vs OPA

OPA is a powerful general-purpose policy engine. PermitNetworks is purpose-built for authorizing AI agents with sub-millisecond latency, built-in budget controls, and cryptographic audit trails.

Feature-by-Feature Comparison

Feature
OPA
PermitNetworks
Primary Purpose
General-purpose policy engine for any domain
Purpose-built authorization for AI agents
Decision Latency
2-15ms (sidecar deployment)
<1ms (edge-native evaluation)
Spending Limits
Manual implementation required
Built-in budget enforcement per agent
Audit Trail
External logging integration needed
Merkle-tree cryptographic proof built-in
Agent-Aware
No — treats all callers the same
Yes — agent identity, task context, session scope
Setup Time
Days to weeks (Rego learning curve)
5 minutes with guided onboarding
mTLS Encryption
Optional, requires manual configuration
Mandatory on every decision path
Rate Limiting
External service required (e.g., Envoy)
Built-in per-agent rate limiting
Policy Language
Rego (custom DSL, steep learning curve)
Declarative YAML + visual editor
Deployment Model
Sidecar or daemon, self-managed
Managed edge network, zero infrastructure
O

When to Use OPA

  • •You need a general-purpose policy engine across many domains
  • •Your team is already proficient in Rego and has existing policies
  • •Authorization decisions are not latency-sensitive
  • •You need to enforce policies on Kubernetes admission control
  • •Your use case does not involve AI agents or autonomous systems
  • •You have dedicated infrastructure teams to manage sidecars
P

When to Use PermitNetworks

  • You are deploying AI agents that make autonomous decisions
  • Sub-millisecond authorization latency is a requirement
  • Agents handle financial transactions or sensitive operations
  • You need cryptographic proof of every authorization decision
  • Regulatory compliance requires tamper-proof audit trails
  • You want built-in spending limits and rate controls per agent
  • Your team needs to ship fast without learning a custom DSL
  • Edge-native deployment with zero infrastructure management

Why Teams Switch from OPA

OPA was built before the era of autonomous AI agents. Here is what you gain by switching to PermitNetworks.

10x Faster Decisions

Edge-native evaluation delivers sub-millisecond latency compared to OPA sidecar overhead of 2-15ms per decision.

Zero Rego Required

Define policies in declarative YAML or use the visual editor. No custom DSL to learn, maintain, or debug.

Cryptographic Proof

Every decision is anchored to a Merkle tree. Auditors get tamper-proof evidence, not just log files.
