Product
Everything it does, and nothing it doesn’t.
This page lists only what is shipped and running in production today. One agent per server, a list of what needs you, and the evidence behind every line.
Know what needs you
The dashboard answers one question: what requires my attention today?
Actions
Derived from the evidence and ranked by severity: an exposed service, a disk filling at today’s rate, a pending kernel reboot, a silent agent. Fix the cause and the Action goes away by itself; dismiss one and it comes back only if things get worse.
Health Score
One number per server, from six factors — capacity, updates, security, exposure, availability and agent — each showing what cost it points.
Notifications
Email, Slack or a webhook, once per situation rather than once per check. Silence a server, or set how long it may go quiet before anyone is woken up.
Search
A ⌘K palette to jump to any server, domain or agent.
See every server
One agent per host, and a page per server that tells its whole story.
Metrics
CPU, memory and disk usage, kept 48 hours at full resolution, then downsampled and kept for 90 days and two years.
Packages & updates
The installed inventory, pending security updates, apt history, and whether updates install themselves.
Services
The systemd units on the host and their state — including the ones that failed, how, and how often they restart.
Reachability
When an agent goes quiet, Demerzel probes the host from outside, so you know whether the server or only the agent is down.
Uptime milestones
Long uptimes, noticed as they are crossed — and ready to share with the client who pays for them.
Notes, groups & names
Rename servers, group them, and leave notes for whoever comes next.
Catch what is about to break
The slow problems, flagged while they are still tasks.
Certificates
Every certificate seen on the host and probed from outside, sorted by soonest expiry.
Domains
The sites each server hosts, and whether each serves valid HTTPS.
Vulnerabilities
Installed packages matched against OSV advisories, per server and across the fleet.
End of life & reboots
Operating systems past support, and kernels installed but not yet running.
Capacity runway
How long until a disk is full at the current rate, and servers too big or too small for their load.
Defend
From explaining an attack to stopping the next one.
Security checklist
Sixteen checks per server — SSH by key only, no exposed database, phpMyAdmin behind a basic auth, a firewall, security updates — each with the evidence and the fix.
Incidents
Attacks rebuilt from web and SSH logs into a timeline of cause, impact and response.
IP dossiers
For every attacking address: what it tried, on which sites, when, and every block applied — by Demerzel or by fail2ban.
Active Defense
Six explainable rules, enforced by a separate warden after a replay of your own logs proves they spare your visitors.

Early access. A ban on one server protects the others; an unban lifts it everywhere. Signed with your organization’s key.

Roles
Owner, admin and read-only, enforced server-side.
Activity log
Who enrolled, renamed, shared, silenced or unbanned what, and when.
Public share
Show a client their server’s health as a page, a badge or a card — revocable at any time.
Passkeys
Sign in with Face ID or Touch ID; an emailed code remains the fallback.
