For agencies and IT service providers
Manage customer servers without the night shift.
You run servers for customers, often with WordPress or a shop. Sentinel takes over the management routine on all of them; in the Fleet plan, every customer gets their own access, where they read the audit log of their servers.
What you get
One control center for all servers.
Know every morning which server needs attention.
The AI’s morning report sums up the whole fleet in a few sentences. The exposure report shows for each server which actively exploited vulnerabilities affect it, whether a fix is available and what comes first. All customer servers are in one place instead of twenty hosting accounts.
Every customer sees only their own servers.
In the Fleet plan, every customer gets their own access to the control center, with their servers and the maintenance reports for them. Notifications go to you; emergency stop and approvals stay with you. That way you answer the question “Is my server secure?” with a link instead of an email.
Proof
Every customer reads their own audit log.
Every action is in the audit log with a checksum chain: what was checked and what was installed or rolled back. If a customer asks about patch status or proof of maintenance, you give them the access; everything is there, with the time.
WordPress plugins one at a time
Sentinel updates WordPress plugins one at a time and checks after each one whether the site still runs. If something goes wrong, it rolls back exactly that plugin. Sentinel does not update the WordPress core automatically, and it does not roll back changes a plugin makes to the database.

Customer data
Separated per customer, and the AI can be switched off.
Data and audit log are separated per customer. Here too, only trimmed excerpts go to the AI; if you do not want that, switch the AI off in Settings, and maintenance continues. The data processing agreement is part of the setup.
How the numbers work
Buy at €29, sell server management.
From 25 servers, the Fleet plan applies: €29 per server per month, €22 from 100 servers, net, with a 12-month term. Below that, the Maintain plan at €37, cancelable monthly, without customer access.
A sample calculation: you pay €29 for a customer server and charge your customer €79 a month for server management with nightly security updates, checks, a rollback path and an audit log. That is well below the €100 to €150 that service providers charge as a flat fee, and leaves you €50 per server per month for your own service. What you charge the customer is up to you.
- What Sentinel takes over.It installs security updates usually within an hour, as far as the risk class allows, and anything bigger in the maintenance window. It checks before and after, rolls back on errors and blocks attackers at SSH access. Exposure report, morning report and audit log are included.
- What stays with you.Everything a human has to decide, and everything your customers value about you: advice, projects, the phone call when something breaks.
- What Sentinel does not do.It does not detect attacks on web applications or malware. Rocky Linux, AlmaLinux and RHEL are only monitored by Sentinel, Windows not at all.
All prices net, plus VAT, for businesses only. The sample calculation is not a price recommendation. Your numbers in the cost calculator.
Getting started
Start with one client server.
In the pilot program Sentinel runs free of charge for six months on up to five client servers of your choice, apply by 30 November 2026. For fleets of 25 servers or more we will make you an offer.
- Pilot program.10 places, 6 months free of charge for up to 5 servers, afterwards a permanent €18.50 instead of €37. In return we want your feedback. Terms and application.
- Fleet.From 25 servers, with customer access. The control center runs with us, with the AI included in the price, or on a small virtual machine of yours with your own AI key.
- What every server needs.Ubuntu or Debian (in operation so far Ubuntu 18.04 to 26.04), SSH access for the control center and a dedicated user with a key and a sudo rule; the setup assistant generates the key. For WordPress additionally WP-CLI and the “Full” level. Sentinel installs nothing.
