Standard Terraform diffs show field changes, not their effective network meaning. PlanReach applies a domain-specific theorem prover to compute exact, finite network-flow changes locally on your machine before terraform apply runs.
These are not hypothetical scanner findings. Small configuration changes can alter effective access across a cloud environment without making the risk obvious in a field-level diff.
Pipe your plan JSON into PlanReach. No database, SaaS control plane, or agent is required.
Run terraform show -json tfplan or tofu show -json plan.tf directly in your CI pipeline or terminal.
PlanReach resolves security-group references, CIDR overlaps, protocols, and port ranges to compute the exact set difference in network reachability.
Set --fail-on added to block unintended public ingress automatically in GitHub Actions, GitLab CI, or Jenkins.
A field-level diff is not an effective-flow proof. PlanReach resolves network reachability across security-group chains with checked, deterministic semantics.
cannot_prove status when required plan parameters are indeterminate
Hope is not a security control. Guesswork has no place in infrastructure access.
Most teams start with a small branch plan. Prove the workflow locally, then move to Unlimited when your plan boundary becomes real.
