The Problem

Terraform reviews are
harder than they look

A small Terraform diff can silently change security boundaries, expose resources to the internet, double your cloud bill, or break a production service. Most reviewers don't catch this in a 5-minute PR review.

IAM Permission Sprawl

A single resource block can grant overly broad IAM permissions that persist long after the PR is merged.

Silent Network Exposure

Changing a security group or S3 bucket policy can expose resources to the public internet with no visible warning.

Missing Encryption

RDS, S3, and EBS resources ship without encryption by default. A missing flag is easy to overlook in a diff.

Unexpected Cost Spikes

Resizing an instance or adding a managed service can add hundreds of dollars per month to your cloud bill.

Too Much CI Noise

Security tools, cost tools, and linters each produce separate logs. Reviewers don't know where to look first.

Style and Drift

Inconsistent naming, missing tags, and formatting issues accumulate across repos with no central enforcement.

The average Terraform PR touches 6+ resource types and is reviewed in under 4 minutes

The Solution

One review comment.
All the important signals.

InfraGuard AI collects output from security scanners, cost estimation, and style linters, then creates a single ranked and readable summary directly in your Pull Request.

AI Boundary

AI explains.
It does not decide.

β€œ

Deterministic tools find the facts. AI explains them. Humans approve the change.

Deterministic Tools

Find the facts

tfsec, Checkov, Infracost, and tflint produce structured, reproducible output based on policy rules β€” not AI guesses.

Security rule violations
Cost estimates
Lint errors
Format failures

AI Layer

Explains the impact

Claude reads scanner output and rewrites it as plain language β€” what the risk is, why it matters, and how to fix it.

Plain-language summaries
Remediation steps
Severity context
Risk explanation

Human Reviewers

Make the final decision

Engineers see full context in one place and decide whether to approve, request changes, or block the PR.

Approve PR
Request changes
Block on severity
Override with context

The AI never invents findings. Every risk, cost change, and style issue traces back to a specific scanner rule and line of Terraform code.

How It Works

From PR to review comment
in one automated step

InfraGuard AI integrates directly into your GitHub Actions workflow with a single configuration file.

Step 1

Pull Request Opened

A developer opens or updates a PR with Terraform file changes

Step 2

Terraform Detected

GitHub Actions triggers automatically on .tf file changes

Step 3

Scanners Run

tfsec, Checkov, Infracost, and tflint execute in parallel

Step 4

Findings Normalized

Raw scanner JSON is parsed, deduplicated, and ranked by severity

Step 5

AI Explains Impact

AI summarizes each finding in plain language with remediation steps

Step 6

PR Comment Updated

One structured comment appears with all findings and context

GitHub Actions integration

One workflow file. Works on every PR automatically.

Demo

What the PR comment
actually looks like

A single, always-current comment. Every finding explained. Ready to act on.

Style

Highaws-s3-block-public-acls

S3 bucket has public ACL enabled. This exposes all bucket contents to the internet.

modules/storage/main.tf:42

Fix: Set block_public_acls = true in aws_s3_bucket_public_access_block

Mediumaws-s3-encryption-customer-key

S3 bucket is not using server-side encryption with customer managed keys.

modules/storage/main.tf:38

Fix: Add server_side_encryption_configuration block with aws:kms algorithm

Mediumaws-iam-no-policy-wildcards

IAM policy contains wildcard action (*) which grants excessive permissions.

modules/iam/policy.tf:18

Fix: Replace wildcard with specific actions: s3:GetObject, s3:PutObject

Do not merge

1 high severity security finding requires remediation before merge. Public S3 bucket access poses significant data exposure risk.
