tfsec VS atlantis

3. tfsec: https://github.com/aquasecurity/tfsec tfsec uses a suite of security checks to scan your Terraform templates, helping to identify potential security issues before infrastructure is deployed.

tfsec Owner/Maintainer: Aqua Security (acquired in 2021) Age: First released on GitHub on March 5th, 2019 License: MIT License tfsec project is no longer actively maintained in favor of the Trivy tool. But because many people still use it and it's quite famous, I added tfsec to this comparison. However, I recommend against using it for new projects.

‍Tfsec acts as a Terraform scanning tool. It is a security-focused linter for Terraform that scans code for security flaws, offering an additional layer of security assurance and helping to maintain a strong security posture.

You can give tfsec a try perhaps

Great toolchain, including Infracost or tfsec.

TFSec is an open-source tool for scanning and detecting potential security vulnerabilities in Terraform code in both HCL and JSON.

We use https://github.com/aquasecurity/tfsec we found checkov.io to be quite noisy

Beyond Snyk and Checkov - I have also used https://github.com/aquasecurity/tfsec at a few organizations both for use locally and in CI (PR Review Checks)

None of these are a replacement of Terraform Cloud (recently rebranded to HCP Terraform). For example, when you create a PR, it could affect multiple workspaces. The new experimental version of TFC/TFE (I refuse to call it HCP!) implements Stacks, which is something like a workflow, and links one workspace output to other workspace inputs. None of the open-source solutions, including the paid Digger [0], support this - only the paid one, such as Spacelift [1] (which is the closest to TFC if you ask me). Having a monorepo of Terraform is a common design pattern, so, if I change an embedded module, it could trigger changes it many workspaces. As far as I know, Atlantis [2] can't really help in this case.

By the way, the reason I singled-out Spacelift is due to its quality, and the great Terraform provider it has. Scalr [3], for example, has a really low-quality Terraform provider. I extensively use the hashicorp/tfe provider to manage TFC itself.

Atlantis is a pull request automation tool that works well with plain Terraform right away. But what if we're already using Terramate to generate Terraform code?

Atlantis automates reviewing and deploying Terraform via pull requests, streamlining collaboration and ensuring consistency across Terraform deployments.

For example, Atlantisgo for Terraform, Zapier’s Kubechecks for Argo CD, Quizlet’s GitHub action all do something similar to this. But a generic, extensible tool for IaC providers doesn’t seem to exist. Additionally, many of them require exposing your Kubernetes cluster or other infrastructure to third-party access, webhooks, etc.

Our first attempt was to introduce other engineering teams to Terraform - the Platform team was already using it extensively with Terragrunt, and using Atlantis to automate plan and apply operations in a Git flow to ensure infrastructure was consistent. We'd written modules, with documentation, and an engineer would simply need to raise a PR to use the module and provide the right values, and Atlantis (once the PR was approved by Platform) would go ahead and set it up for them.

Alternatively, you can look at solutions like Atlantis or spacelift.

Looking at the commits at https://github.com/runatlantis/atlantis, it looks like 1.6.5. Am I right?

We use Atlantis [0] for CI/CD automation of Terraform pull requests to a centralized repository. It's pretty good too, especially for a self-hosted solution. I can't see how Terraform Cloud's costs would be justifiable for us without a custom contract.
