The most boring chart you own. We keep it that way.
up4 can watch your sites, APIs and scheduled jobs as often as every 10 seconds. Every monitor-region execution is metered or drawn from a plan budget. When the line does something interesting, the right person knows — and your client never has to.

Six minutes of downtime, documented. White-label, already in their inbox.
An outage can hide for five minutes. Or for ten seconds.
Every dot is one check across a five-minute window. A 10-second interval is available on every plan here; each execution is metered or drawn from the flat plan’s monthly check budget.
A five-minute outage is 30 chances to catch it — or one. With quorum across regions and two-check confirmation, faster never means noisier.
Your clients, kept apart. Your name on everything.
Client accounts partition everything. Monitors, incidents, status pages, reports — scoped per client. Lakeside never sees Verde, and neither do Lakeside’s logins.

White-label reports. Monthly SLA evidence as PDF, with your logo and your domain. The work is yours; the paperwork should look like it.

Monitoring is a trust business. So, some facts.
● EU-hosted, GDPR-native
German infrastructure, data stays in the EU, a signed DPA for your client contracts — and no cookie banner on this page, because there is nothing to consent to. How it is actually run
● We publish our probes
Fixed egress IPs, an honest user agent, and a status page that doesn’t run on the infrastructure it reports on. The current list
● Secrets are encrypted, sessions are revocable
Channel credentials are AES-256-GCM encrypted before storage; browser sessions are opaque tokens whose hash is all we keep. You can revoke any of them, from any device.
● What we do not have
No SOC 2, no ISO certificate, no SAML. We publish that next to the things we do have, because a trust page that only lists wins is worth nothing. The gaps, named

up4 is built and run by Dennis Wissmann in Düsseldorf. Support and engineering are the same desk, which is why a reply takes a day rather than a ticket queue. Say hello
