Pricing

Priced per endpoint, not per promise.

Every plan includes the full detection engine, automated response, the geo threat map, data loss prevention, the audit log and GDPR self-service. Higher plans add scale, integrations and retention — never the detection itself.

What is not charged extra

  • Every detection rule and every response action
  • Exporting your own data, in any format
  • Additional users on the console
  • Connecting your own AI provider
  • Support during the trial

What you may pay someone else for

  • Your AI provider's usage, if you connect one — billed by them, not by us
  • Threat-intel lookups on your own VirusTotal or AbuseIPDB keys

We would rather tell you this here than in an invoice.

Pricing questions

What counts as a device?

Anything with the agent installed and enrolled. Servers and workstations count the same. Your subscription is for the number of devices set when you subscribe; change that number in the billing portal as your estate grows or shrinks. A device you remove stops counting towards your plan's device limit.

Do I pay during the trial?

No. You do not need a card to start. If you choose a plan during the trial, your card is taken at checkout but not charged until the trial ends; after that you are charged monthly until you cancel. If you do not choose a plan, the console becomes read-only at the end of fourteen days and nothing is charged.

Can I cancel?

Yes, at any time in the billing portal. Cancellation takes effect at the end of the month you have paid for. See the refunds & cancellation policy.

Can I self-host?

By agreement. The server is a single Python application with SQLite or PostgreSQL behind it; contact us to discuss a self-hosted licence.

What happens to my data if I cancel?

Export everything as a workbook first. On request we delete your workspace and confirm in writing; see the data processing terms for timings.
