We let you know when something breaks..
Guard checks your sites, certificates, servers and user journeys around the clock. When something goes wrong, you hear about it right away.
How it works
Live in under two minutes
Add a URL. We start monitoring from four continents. You get alerted the moment anything moves.
Add what you want watched
A URL, a server or a user journey. You don't have to touch your DNS and there's nothing to configure.
We keep track of it
Checks run every 60 seconds from four regions, or every 30 with the speed add-on, covering SSL, DNS, performance and security headers.
You get an alert with context
When something breaks, you see where it went wrong and since when. That saves digging when you get pulled in at night.
Features
Everything in one place
Sites, servers, certificates, DNS, browser flows and security. One product and one bill, instead of five separate tools.
Monitoring
08Uptime, watched in real time
Checks every 60 seconds from four regions, or every 30 with the speed add-on. The moment a site dips, you know.
Certificates that never surprise you
We track every SSL chain on your domains and warn you weeks before anything expires.
Truth from four continents
Monitor from the Netherlands, Germany, the United States, and the United Kingdom. Catch regional outages a single check would miss.
Built for the speed of the web
Intervals from 30 seconds, sub-second checks. By the time you refresh the dashboard, the next probe has finished.
DNS drift, caught instantly
Records that change without warning are how outages start. We watch every record and alert on every diff.
A lightweight agent, deep visibility
Drop our Go agent on any server. CPU, memory, disk, network, processes, all streamed live with per-device tokens.
Backend traces and errors
Drop our SDK into Next.js, Remix, or Express. Stream traces, exceptions and slow endpoints into the same dashboard as your uptime.
Content and resource change detection
Get a diff the moment a page, script, or critical resource changes. No more silent deploys breaking production.
Security
05Security scans on every domain, continuously
Vulnerabilities, missing headers and weak SSL configs, each with a grade and an explanation of what to do about it.
Email authentication, verified continuously
SPF, DKIM, and DMARC records checked on a schedule. Get alerted the moment misconfiguration opens your domain to spoofing.
CVE alerts before they become incidents
New CVEs matched to your stack the moment they're published. Patch decisions backed by real exposure data, not guesswork.
Synthetic monitoring in a real browser
Script the journeys that pay your bills (login, checkout, search) and watch them run on real browsers, on a schedule.
Accessibility, on a schedule
WCAG 2.1 crawls of your public pages, with a fix list per finding. Catch regressions before legal does.
Analytics & SEO
03SEO signals, watched alongside uptime
Title tags, meta descriptions, canonical URLs, robots directives. Track every change and catch regressions before rankings drop.
Backlink changes, surfaced automatically
Know when high-value links appear or disappear. Spot toxic links early and protect your domain authority.
Real user data, straight from the browser
Lightweight RUM script measures Core Web Vitals and page load times for real visitors: per page, per region, over time.
Alerts and Reporting
04Alerts that reach you, wherever you are
Email, Slack, Discord, Teams, Telegram, webhook and MCP. You decide where an alert lands.
Incidents, end to end
Every probe, every alert, every retry on one timeline. Acknowledge, group, and resolve without leaving the tab.
Status pages your users actually trust
Public, branded pages that update themselves. Stop drafting tweets at 2 a.m.
The data behind every nine
Latency, availability, regional breakdowns, historical trends. Export anywhere, drill into anything.
Integrations
Plugs into the tools you already live in
Email, Slack, Discord, Teams, Telegram, webhooks, MCP, Azure, Vercel, Coolify and Cloudflare. Connect as many as you like.
Why Guard

How fast can I set up my first monitor?
Under two minutes. Sign in, paste a URL, done. No DNS changes, no agents, no configuration.
What happens when my site goes down?
We tell you instantly through email, Slack, Discord, Teams, Telegram, or a webhook of your choosing. Checks run every 60 seconds from four regions, or every 30 with the speed add-on.
Can I monitor from multiple locations?
Yes. Every monitor runs from the Netherlands, Germany, the United States, and the United Kingdom by default. Regional outages stop hiding.
Do you offer SSL certificate monitoring?
Always on. We track every certificate on every domain you give us and warn you weeks before anything expires.

Real browsers, scripted by you, running on a schedule. Login, checkout, search: anything a user does, you can simulate, and we'll alert you the moment it breaks.
