CostProtect Step 3 of 4

Keep every AI workload inside your rules, with evidence to show it

CostProtect is AI governance that runs: approved models by data class, approval gates and guardrails become policy your gateway enforces, re-checked as prices, models and usage change.

Savings that never break a data, privacy or quality rule
Every policy change versioned, approved and logged
Evidence mapped to EU AI Act, NIST AI RMF, ISO 42001 and SOC 2

1CostAssessSee every AI workload, its cost and its gaps. 2CostWallStop overspend in the gateway you already run. 3You are hereCostProtectAI governance: keep every workload within your rules. 4CostProofSee the savings on your real bill.

Where it fits in AICost.ai

Builds onTakes the findings from CostAssess and the limits from CostWall.

FeedsApproved rules go back into CostWall; evidence from CostProof feeds your audit pack.

What you get

Cost control within your governance envelope

Every cost lever is checked against your data classes, approved vendors and quality floor.

Approvals with a record

Owners sign off; every change is a new version with a diff.

Always re-checked

Assurance tests re-run on every price, model or policy change.

Audit-ready evidence

One evidence journal for your auditors, regulators and board.

How it works

Detect
Drift, a new model, a price change or a new workload is spotted by the engines.
Propose
A new policy version with the cost and risk effect of the change.
Approve
The owner signs off; the diff and the reason are recorded.
Deploy
The rule goes to your gateway and is tested before it counts.
