PolicyGuard pre-validates network and IaC changes against compliance rules using OPA/Rego policy engines, catching violations before production deployment.
Overview
PolicyGuard analyzes every proposed network or infrastructure-as-code change against defined compliance policies, security baselines, and business intent before it is deployed. Violations, drift, and high-risk changes are flagged with a clear compliance score, giving change approvers objective evidence to approve, reject, or request modification.
By shifting validation left - before deployment rather than after an incident - PolicyGuard reduces rollback risk, strengthens audit posture, and speeds up the change approval process without sacrificing governance.
Integration and Technology
PolicyGuard leverages OPA/Rego policy engines for precise, transparent rule evaluation and supports Terraform and OpenTofu infrastructure-as-code workflows. On AWS, PolicyGuard complements AWS Config rules and AWS Network Firewall policies by providing an additional pre-deployment validation layer that catches violations before changes reach your environment. Integration with change management platforms enables automated policy checks within your existing CI/CD and change advisory board workflows.
Key Feature Set
- Automated pre-deployment policy and compliance checks using OPA/Rego
- Configuration drift detection against approved baselines
- Change risk scoring (low / medium / high) with CWE mappings
- Regulatory and internal-policy rule libraries (PCI-DSS, SOX, NIST, and custom frameworks)
- Change-compliance trend and audit reporting
- Transparent findings with remediation guidance and fix recommendations
Engagement Process
PolicyGuard is delivered as a managed service engagement structured in defined phases:
- Discovery and Scoping - UST assesses your network estate, existing policies, and compliance requirements to define engagement scope.
- Baseline Configuration - Policy rule libraries are tailored to your regulatory obligations and internal standards.
- Integration and Deployment - PolicyGuard is connected to your change pipelines, IaC workflows, and AWS environment.
- Validation and Tuning - Initial changes are scored and results are reviewed with your team to refine thresholds.
- Go-Live and Handoff - Ongoing monitoring is enabled with compliance dashboards, runbooks, and team training delivered.
Key Benefits
- Reduces change-related rollback risk by up to 89%
- Speeds up change advisory board decisions by up to 2x
- Strengthens regulatory audit readiness with automated evidence collection
- Prevents unauthorized configuration drift across your estate
- Lowers the operational risk of every production change
Use Case Scenario
A financial services organization managing hundreds of branch-office firewalls and cloud security groups under PCI-DSS obligations uses PolicyGuard to validate every proposed rule change before deployment. Each change is scored against PCI-DSS controls and internal baselines, producing an audit-ready compliance report that the change advisory board reviews in minutes rather than hours. Drift detection continuously monitors for unauthorized modifications between audit cycles.
Prerequisites and Scope
- Supported environments: AWS networking services, Terraform/OpenTofu IaC, and traditional network infrastructure
- Buyer provides: access to network configurations, existing policy documents, and relevant compliance framework requirements
- AWS account with appropriate IAM permissions for integration
- Best suited for enterprises managing complex multi-device or multi-account network estates under regulatory obligations

Highlights
- PolicyGuard uses OPA/Rego policy engines to score every proposed network or IaC change against regulatory frameworks (PCI-DSS, SOX, NIST) and internal baselines before deployment, producing audit-ready compliance evidence that eliminates manual policy review. Unlike generic scanning tools, PolicyGuard provides transparent findings with CWE mappings and specific remediation guidance for each violation detected.
- Reduces change-related rollback risk by up to 89% and accelerates change advisory board approvals by up to 2x by replacing subjective human review with objective, automated risk scoring. Each change receives a low, medium, or high risk classification with clear justification, enabling approvers to make faster decisions backed by quantifiable compliance data.
- Integrates with Terraform, OpenTofu, AWS Config, and AWS Network Firewall to provide continuous pre-deployment validation within existing CI/CD pipelines and change management workflows. Configuration drift detection monitors your approved baselines and flags unauthorized modifications, maintaining compliance posture between audit cycles across your entire network estate.
