Review faster with context

“With tfRails, we are able to review, troubleshoot and act on each IaC PR between 4x to 10x faster.”

Shift left

“Getting a complete understanding of the impact of each change on our environments and adding automatic testing for resilience, security & cost before deployment– all while shifting left ownership, made the decision a no-brainer.”

Reviewing terraform plans for change assessments is not an optimal approach to say the least...
When using traditional scanners and tf_plan you are missing critical aspect:

The context and potential impact on your environment.

Don't Scan.


Now you can fully understand
the impact of any change.

Identify the availability, security, and cost impact of proposed configuration changes before you deploy.
Terraform AWS IAM change impact
See how changes to an IAM policy can impact a K8s pod that is already running.
Terraform change impact
tfRails mimics AWS behavior and simulates all resources that will be created post apply,
such as EC2 instances, ENIs, and EBS volumes for an ASG created with a launch template.
Terraform change topology visualization
Observe the effects of the modification with a topology graph.
terraform aws change simulation
Identify deviations from best practices before they become harder to remedy.
Shift-left Cost, Resilience, Security and Compliance!
tfRails covers your terraform PRs with context-aware policies.
terraform aws security validation
Security & Compliance
Shift left Compliance, CSPM and CIEM to the PR stages, tfRails is the only tool that merges your runtime state to the build stage with the full posture.
terraform aws cost validation
Cloud Costs
Validate each change is optimized for cost best practices and your organizational standards.
See the predicted implications on your bill before deployment.
terraform aws resilience validation
Make sure your architecture is resilient before deployment while Terraform changes are still easy to fix.
Easily tune controls and enforce custom-made posture based architectural standards.
AWS guardrails
Terraform policies
Example #1

Expect only the billing microservices to access billing DynamoDB table.

terraform guardrails
Example #2

Connectivity across regions should be via TGW and not VPC Peering.

Make config changes
without breaking things.

reduce terraform review times
Accelerate and simplify the complex Terraform plan analysis.
terraform change risk
Identify high-risk changes that are otherwise hard to predict on a Terraform plan.
terraform change impact
Predict potential availability issues that may break things and cause downtime.

How does it work?

tfRails Simulation engine merges the current running state of your cloud (actual state not tfstate) in a combination with the Terraform code proposed change, to determine how your cloud is going to be impacted if the code gets applied, Learn more.
