Terraform Security: Best Practices with Sentinel & OPA

Policy-as-Code → Secure. Compliant. Fast.

As teams scale Infrastructure as Code (IaC) with Terraform, security challenges grow. The key question: How do you keep infra secure & compliant without slowing down delivery? 👉 Answer: Policy-as-Code with Sentinel & OPA.

Best Practices

• Block risky resources (open SGs, unmanaged buckets).
• Standardize tags, naming conventions & cost controls.
• Enforce least privilege IAM policies.
• Automate GDPR, HIPAA, PCI-DSS compliance checks.
• Integrate policy checks into CI/CD (GitHub Actions, Jenkins, Terraform Cloud).

Sentinel vs OPA

Sentinel • Best for HashiCorp ecosystem.
• Native Terraform Cloud support.
• Tight integration, easy adoption.

OPA • Flexible & cloud-agnostic.
• Great for multi-cloud & Kubernetes.
• Wide community adoption.

Takeaway: Security as Code = predictable, compliant, resilient infra — without slowing DevOps velocity.
