SENTINEL
DEEN

Pilot program

Six months free of charge, in return for your feedback.

Sentinel has been running in our own operations since 10 September 2026. For the next step, we are looking for ten companies that use Sentinel on up to five servers and tell us what is missing. Apply by 30 November 2026.

The terms

What you get, what we would like in return.

The Maintain plan, without an invoice.

  • Up to 5 servers on the Maintain planwith everything that comes with it: security updates, checks and rollback path, blocks, exposure report, morning report, audit log. Equivalent value €1,110 net.
  • After that, €18.50 instead of €37 permanentlyper server per month for these up to five servers, for as long as the contract runs. Cancel monthly. Additional servers at the regular price.
  • No payment details, no automatic renewal.After the six months, you decide. If you say nothing, the program ends.
  • A direct line to the founders.Your feedback does not end up in a ticket system, but with the people who build Sentinel.

Just under two hours of your time, spread over half a year.

  • 45 minutes of joint setupof the first server, by video call. You set up additional servers yourself with the wizard, or with us again.
  • Two 30-minute conversationsafter 2 and after 8 weeks: what helped and what is missing.
  • After 60 days, one sentence or one figurethat we may quote. With or without your company name, that is your decision. If Sentinel has not convinced you, say that too. Then we quote nothing.

Who it is for

Who we are looking for, and who we are not.

Companies and agencies with two to fifty Linux servers running Ubuntu or Debian that today do the maintenance themselves, pay a service provider by the hour, or do not maintain regularly at all. There should be someone who can hold the conversations: IT management, executive management, or the admin who does the updates today.

Not suitable: Windows servers, servers without SSH access from outside, and environments in which a dedicated user with a sudo rule is not permitted. Sentinel only monitors Rocky Linux, AlmaLinux and RHEL, and Windows not at all.

We allocate the places in order of receipt and according to whether your environment fits. If it does not, we decline and state the reason.

How it works

From application to the first morning report.

  1. By 30 Nov

    Apply. Via the 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 at the “Observe” level and changes nothing.

  3. Week 2

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

  4. Week 8

    Second conversation. Six weeks of maintenance with an audit log are on record. 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, for businesses only. The program ends when the ten places have been allocated or on 30 November 2026, whichever comes first.
