Pricing

Pricing that scales with what you govern.

Castle Entropy is priced on the data and AI assets you put under governed control — not per seat, not per byte. Start with a free pilot, then grow into a plan that fits your estate.

How pricing works

You pay for what you govern

A governed asset is an approved data or AI record placed under an active retention or lifecycle policy. We count records under governance, not bytes stored.

Derivatives are included

Tracking the summaries, copies, and related records your governed assets produce is core to the product — not a separate meter.

Growth handled with notice and true-up

We notify you before capacity becomes an issue. Plan changes, overages, and expansion are handled through renewal, true-up, or the terms in your agreement.

Start free, grow with a conversation

Begin with a 30-day pilot on a scoped set of assets. When you're ready, we'll scope a plan to your environment.

Questions

Is there a free trial?

Yes — a 30-day pilot on a scoped set of assets, so you can see the workflow and the evidence records before committing.

How is pricing calculated?

On the governed assets you put under active policy. Tell us about your estate and we'll scope a quote.

Do you offer a DPA?

Yes. A Data Processing Addendum is available and is required before processing production personal data.

What if I outgrow my plan?

We notify you as you approach the limit, and sustained growth is reconciled at renewal, applied going forward.

Not sure which plan fits?

Start with a pilot, or tell us about your environment and we'll help you scope it.
