Q-Trust Plane vs. Alternatives

Executive Summary

Q-Trust Plane is the only cryptographic zero-trust control plane that provides unified governance across Web3, Kubernetes, Terraform, MLOps, and CI/CD with complete audit trails and cryptographic proof.

Key Differentiators:

• Cross-domain: One policy language for all infrastructure domains
• Cryptographic: Signed grants with evidence binding
• Complete audit trail: Immutable, blockchain-anchored
• Open source: No vendor lock-in
• Self-hosted: Your data stays on your infrastructure

vs. Open Policy Agent (OPA)

Overview

OPA is a general-purpose policy engine primarily used for Kubernetes admission control and API authorization.

Comparison

When to Use OPA

• You only need Kubernetes policy enforcement
• You're already invested in Rego
• You need a lightweight sidecar model
• You don't need cryptographic grants or complete audit trails

When to Use Q-Trust Plane

• You need cross-domain governance (Web3, K8s, Terraform, MLOps, CI/CD)
• You need cryptographic proof of authorization decisions
• You need complete, immutable audit trails
• You need blockchain anchoring for compliance
• You want a unified policy language across all domains

Migration Path

Q-Trust Plane can coexist with OPA. You can:

1. Keep OPA for K8s admission control
2. Use Q-Trust Plane for cross-domain governance
3. Gradually migrate OPA policies to QPL

vs. Kyverno

Overview

Kyverno is a Kubernetes-native policy engine that uses YAML for policy definition.

Comparison

When to Use Kyverno

• You only need Kubernetes policy enforcement
• You prefer YAML over code
• You want a K8s-native solution
• You don't need cross-domain governance

When to Use Q-Trust Plane

• You need cross-domain governance beyond K8s
• You need cryptographic proof and complete audit trails
• You need Web3, Terraform, or MLOps governance
• You want a unified policy language

Migration Path

Q-Trust Plane can replace Kyverno for K8s admission control while adding cross-domain capabilities.

vs. HashiCorp Sentinel

Overview

Sentinel is HashiCorp's policy-as-code framework, primarily used with Terraform Enterprise.

Comparison

When to Use Sentinel

• You only use HashiCorp products
• You're already paying for Terraform Enterprise
• You don't need cross-domain governance
• You don't need cryptographic grants

When to Use Q-Trust Plane

• You need cross-domain governance beyond Terraform
• You want to avoid vendor lock-in
• You need cryptographic proof and complete audit trails
• You want a more cost-effective solution ($3k/mo vs $70k+/year)

Migration Path

Q-Trust Plane can replace Sentinel for Terraform governance while adding cross-domain capabilities.

vs. AWS IAM / GCP IAM / Azure RBAC

Overview

Cloud provider IAM systems for access control within their ecosystems.

Comparison

When to Use Cloud IAM

• You only use a single cloud provider
• You only need cloud resource access control
• You don't need cross-domain governance
• You're okay with vendor lock-in

When to Use Q-Trust Plane

• You use multiple cloud providers
• You need on-premise and cloud governance
• You need Web3, K8s, Terraform, or MLOps governance
• You need complete audit trails with cryptographic proof
• You want to avoid vendor lock-in

Integration

Q-Trust Plane can integrate with cloud IAM systems:

• Use cloud IAM for resource access
• Use Q-Trust Plane for policy governance and audit trails
• Best of both worlds: cloud-native access + unified governance

vs. Styra DAS (Declarative Authorization Service)

Overview

Styra DAS is a commercial product built on top of OPA, providing a management layer and UI.

Comparison

When to Use Styra DAS

• You're already using OPA extensively
• You need a UI for OPA management
• You don't need cross-domain governance
• You're okay with SaaS deployment

When to Use Q-Trust Plane

• You need cross-domain governance
• You need cryptographic proof and complete audit trails
• You want a more cost-effective solution
• You prefer self-hosted deployment

vs. Rego (OPA's Policy Language)

Policy Language Comparison

Example: Require Audit Report

QPL:

policy "require-audit" {
  domain = "web3"
  
  rule "audit-exists" {
    condition = evidence.audit_report.exists
    action = "allow"
  }
}

Rego:

package web3

default allow = false

allow {
  input.evidence.audit_report
}

When to Use QPL

• You want a SQL-like, declarative syntax
• You need domain-specific features (Web3, K8s, etc.)
• You want first-class evidence handling
• You prefer strong typing

When to Use Rego

• You're already invested in OPA
• You need general-purpose policy evaluation
• You're comfortable with functional programming
• You need maximum flexibility

vs. Manual Processes (Approvals, Reviews, etc.)

Comparison

When to Use Manual Processes

• You have very few authorization decisions (<10/month)
• You need human judgment for every decision
• You have unlimited time and budget
• You don't need compliance or audit trails

When to Use Q-Trust Plane

• You have frequent authorization decisions (>10/day)
• You need consistent, automated enforcement
• You need complete audit trails for compliance
• You want to reduce operational overhead
• You need 24/7 availability

Hybrid Approach

Q-Trust Plane can integrate with manual processes:

• Automated policy evaluation for most cases
• Human approval required for high-risk actions (via evidence)
• Best of both worlds: automation + human oversight

Feature Matrix

Legend:

• ✅ Full support
• ⚠️ Partial support or requires custom integration
• ❌ Not supported

Pricing Comparison

Notes:

• Q-Trust Plane offers more features than free alternatives (OPA, Kyverno)
• Q-Trust Plane is significantly cheaper than commercial alternatives (Sentinel, Styra DAS)
• Cloud IAM is "free" but locks you into a single provider
