Apply by 30 November 2026.

What happens next.

Sentinel starts on the “Observe” level and changes nothing. It only installs updates once you enable the server.

1. By 30 Nov

   Apply. Use this form with the topic “Pilot place”: how many servers, which system, how you maintain them today. Reply within one business day.

2. Week 1

   Set up. 45 minutes together: user, key, sudo rule, your fixed addresses. Sentinel starts on the “Observe” level and changes nothing.

3. Week 2

   First call. You have seen the first morning reports and the exposure report. We discuss which level you approve.

4. Week 8

   Second call. Six weeks of maintenance with an audit log are on the table. What was missing, what was too much.

5. Month 6

   Decide. Continue at €18.50 per server, or stop. Remove the user and the sudo rule, and Sentinel is gone.

The pilot agreement and the data processing agreement come with our reply. All prices net, plus VAT, businesses only. The program ends when the ten places are taken or on 30 November 2026, whichever comes first. All terms

What the pilot needs

• Servers running Ubuntu or Debian. In operation, Sentinel has so far run on Ubuntu 18.04 to 26.04.
• SSH access for our control center at Hetzner in Falkenstein, Germany. We give you the control center's fixed IP address with the pilot agreement.
• A dedicated user with a key and a sudo rule. We create it together.
