How it works?
HashiCorp Sentinel is a policy-as-code framework used to enforce governance and compliance controls across Terraform Cloud/Enterprise and Vault workflows. Platform, DevOps, and security teams use it to codify guardrails that validate infrastructure and access changes before they are applied, helping reduce misconfigurations and improving auditability in multi-team environments.
Policies are evaluated during request and run workflows (such as Terraform plan/apply or Vault access requests), enabling consistent enforcement across CI/CD pipelines and self-service platforms while still supporting controlled exceptions and approvals. For related platform governance practices, see Platform Engineering.
- Pre-deployment checks for Terraform runs (e.g., allowed regions, tagging, network exposure)
- Controls for Vault authentication, authorization, and secrets access workflows
- Versioned, testable policy code that can be reviewed and promoted like application code
- Exception handling and conditional approvals to balance delivery speed and compliance
Infrastructure-as-Code is a way for provisioning infrastructure by describing the state of the infrastructure you want to get as a program that can be interpreted and executed.
- With Infrastructure as Code, you can gain an insight into your infrastructure status swiftly, as it serves as a living document offering a snapshot of your systems' state and configuration.
- Infrastructure as Code allows you to improve your infrastructure using code itself, making the process of introducing new services, upgrading existing ones, or modifying configurations flexible and adaptable.
- Infrastructure as Code facilitates making system-wide modifications efficiently, ensuring consistency across your entire system and reducing error potential.
- Continuous integration principles from software development can be applied to your infrastructure management through Infrastructure as Code, enabling automation in testing and deployment of infrastructure changes.
- Infrastructure as Code enables you to provision entire systems from scratch quickly and reliably, proving to be advantageous in testing, development, and disaster recovery scenarios.
- Monitoring infrastructure state and implementing incremental changes is made possible with Infrastructure as Code, improving auditability and change management.
- By automating repetitive tasks and reducing manual intervention, Infrastructure as Code reduces potential human errors and increases efficiency.
- Infrastructure as Code enhances collaboration and transparency by serving as a common language understandable by both operations and development teams.
- Infrastructure as Code allows for the creation of standard templates for your infrastructure setup that can be used to replicate your environments consistently across different stages of the application lifecycle and multiple projects.
- Infrastructure as Code improves overall security posture and simplifies compliance auditing by allowing the incorporation of security configurations and compliance requirements directly into your infrastructure code.
HashiCorp Sentinel is a policy-as-code framework for enforcing governance and compliance controls in Terraform Cloud/Enterprise and Vault. It is used to codify guardrails that are evaluated automatically at consistent enforcement points in infrastructure provisioning and secrets workflows.
- Blocks non-compliant infrastructure changes by evaluating policies during Terraform plan and apply in Terraform Cloud/Enterprise.
- Centralizes governance by applying organization-level policies across many workspaces, projects, and environments.
- Enforces infrastructure standards such as allowed regions, instance types, tagging requirements, encryption settings, and network exposure constraints.
- Supports separation of duties by letting platform and security teams own policy repositories while delivery teams focus on Terraform modules and pipelines.
- Improves auditability with consistent policy decisions and logs that can be retained as evidence for change control and compliance reviews.
- Makes governance logic versioned and testable through source control, peer review, and automated Sentinel policy tests.
- Reduces misconfiguration risk by preventing insecure defaults and drift-inducing patterns before they reach shared or production environments.
- Standardizes exception handling with controlled overrides and break-glass workflows that can be logged and reviewed.
- Extends enforcement into Vault by constraining secret access patterns, approved paths, authentication methods, and operational controls.
Sentinel is typically a strong fit when Terraform Cloud/Enterprise is the control plane and centralized policy enforcement is required across teams. Trade-offs can include tighter coupling to the HashiCorp ecosystem and fewer cross-platform integrations than general-purpose policy engines.
Common alternatives include Open Policy Agent (OPA) with Rego, Conftest, and cloud-native governance services such as AWS Config and Azure Policy. For background on policy concepts and workflows, see HashiCorp Sentinel documentation.
Our experience with HashiCorp Sentinel helped us turn governance requirements into practical, testable policy-as-code that teams could adopt without slowing down Terraform delivery. Across Terraform Cloud/Enterprise and Vault programs, we implemented Sentinel in a way that made guardrails consistent across workspaces, environments, and pipelines while still allowing controlled exceptions when needed.
Some of the things we did include:
- Assessed existing Terraform and Vault governance, then delivered a prioritized backlog of policy gaps, risk items, and quick wins mapped to audit and compliance objectives.
- Designed Sentinel policy set structures (repositories, shared libraries, naming conventions, and baseline bundles) so platform teams could scale controls across many workspaces and business units.
- Authored Sentinel rules to enforce Terraform standards such as required tags, allowed regions, encryption defaults, network boundaries, and least-privilege IAM patterns with clear, actionable failure messages.
- Implemented phased rollout patterns (advisory vs. hard-fail, environment-specific thresholds, and workspace targeting) to reduce friction while policies matured.
- Built policy test harnesses and CI gates so Sentinel changes were reviewed, unit-tested, and regression-tested before release, reducing noisy failures and unexpected run blocks.
- Integrated Sentinel evaluation outcomes into CI/CD workflows (including GitHub Actions) so policy results were visible alongside plan/apply feedback and change approvals.
- Implemented exception and waiver workflows with auditable approvals (time-bound exceptions, ticket references, and documented rationale) to support real operational needs without weakening controls.
- Created Vault-focused Sentinel checks to validate auth methods, secret engine configuration, namespace boundaries, and access controls aligned to internal security requirements.
- Standardized reusable policy bundles for common cloud patterns (networking, storage, identity, and encryption) and created rollout playbooks to help teams adopt policies consistently.
- Trained platform, DevOps, and security teams on writing, testing, and reviewing Sentinel policies, and established lightweight Git-based governance workflows that fit existing delivery practices.
This experience helped us accumulate significant knowledge across multiple Sentinel use-cases—from Terraform governance to Vault controls—and enables us to deliver high-quality HashiCorp Sentinel setups that are straightforward to operate, easy to extend, and aligned to real delivery constraints.
Some of the things we can help you do with HashiCorp Sentinel include:
- Assess your current Terraform Cloud/Enterprise and Vault governance posture and deliver a prioritized report of risks, gaps, and quick wins.
- Define a policy-as-code adoption roadmap covering policy domains, ownership, rollout phases, and a pragmatic exception/waiver model.
- Design and implement Sentinel policy sets aligned to security baselines, compliance requirements, and operational guardrails.
- Author, test, and version Sentinel policies using maintainable engineering practices (mock data, unit tests, CI checks, and environment promotion).
- Integrate Sentinel enforcement into Terraform workflows and CI/CD gates so non-compliant changes are blocked before they reach production.
- Implement auditable approvals and time-bound overrides with traceable evidence for internal controls and external audits.
- Optimize policy performance and developer experience by tuning enforcement levels, improving error feedback, and reducing false positives.
- Establish cost and reliability guardrails (mandatory tags, allowed regions, resource limits, and environment restrictions) to support FinOps and consistency.
- Enable teams with hands-on workshops, policy authoring training, and operational playbooks to sustain governance at scale.
