Everything Your Infrastructure Monitoring Needs
GDPR-compliant uptime monitoring built for Germany and the EU. Monitor HTTP endpoints, SSL certificates, TCP ports, and DNS — all from one dashboard.
Core Features
Monitor Every Layer of Your Stack
From public-facing APIs to internal services, UptimeGuardian gives you visibility across your entire infrastructure. Set up your first check in under three minutes.
HTTP(S) Endpoint Monitoring
Check your web applications and APIs every 30 seconds from six probe locations across Frankfurt, Berlin, London, Amsterdam, New York, and Tokyo. Validate response codes, measure response times down to the millisecond, and set up body-content matching to confirm your pages are rendering correctly. Get alerted when response time exceeds your threshold — for example, flag any endpoint slower than 2 seconds.
SSL/TLS Certificate Monitoring
Never miss an expired certificate again. UptimeGuardian checks every SSL endpoint continuously and sends escalation alerts at 30, 14, 7, and 1 day before expiry. We validate the full certificate chain, detect weak cipher suites, and flag mismatches between your domain and certificate CN/SAN fields. Integrates with Let's Encrypt, Sectigo, DigiCert, and any public CA.
TCP Port & DNS Monitoring
Monitor any TCP port — databases on 5432, Redis on 6379, custom services on non-standard ports. DNS monitoring verifies A, AAAA, MX, CNAME, and TXT record resolution from multiple global locations. ICMP ping checks confirm host reachability. All checks run every 60 seconds on the Starter plan and every 30 seconds on Professional and above.
Public Status Pages
Share real-time uptime status with your customers through a branded status page at yourcompany.uptimeguardian.de. Each page shows live component health, incident timelines with automatic status updates, and historical uptime percentages. Your subscribers receive email and SMS notifications when incidents occur or resolve. Fully customizable with your logo, colors, and component names.
SLA & Uptime Reports
Generate monthly PDF SLA reports automatically on the 1st of every month. Reports include uptime percentages per endpoint, mean time to detection (MTTD), mean time to resolution (MTTR), and downtime incident logs. Customize the uptime target — 99.9%, 99.95%, or 99.99% — and get a clear pass/fail verdict. Access all metrics programmatically through our REST API or download raw CSV data.
Multi-Channel Alerting
Route alerts through email, SMS, Slack, Telegram, Microsoft Teams, PagerDuty, or custom webhooks. Build escalation policies so that if your on-call engineer doesn't acknowledge an alert within 5 minutes, it automatically escalates to the next team member. Configure quiet hours, deduplicate flapping alerts, and tag alerts by severity — critical, warning, or info.
Why UptimeGuardian
Simplicity Meets Depth
You shouldn't need a DevOps degree to set up monitoring — but you also shouldn't have to sacrifice granularity when it matters.
GDPR-Compliant by Design
All monitoring data is stored exclusively on servers in Frankfurt (Hetzner) and Berlin (Equinix). No data leaves the EU. We process zero personal data from your end users — only infrastructure metrics. Our data processing agreement (DPA) is included at every plan level, and we're ready for your DPO's review.
Three Minutes to First Check
Create an account, enter your endpoint URL, pick a check interval, and you're live. No agents to install, no firewall rules to configure, no SDK to integrate. UptimeGuardian monitors from the outside in, just like your users experience your service. Add team members with role-based access — Owner, Admin, or Read-Only — in one click.
Granular Metrics, Clear Dashboards
Track response time percentiles (p50, p95, p99), certificate expiry countdowns, DNS resolution times, and downtime durations — all on a single dashboard. Set custom uptime targets per endpoint. Our anomaly detection flags unusual response time spikes before they become outages. Data retention is 90 days on Starter, 1 year on Professional, and 5 years on Enterprise.
Built for Teams of Every Size
Freelancers use UptimeGuardian to monitor a handful of client sites. Agencies manage 200+ endpoints across dozens of projects. Enterprises like Merkur Digital and PostFinance run 1,000+ checks with SSO and audit logging. Our platform scales with you — no migration needed when you grow.
