Watch every client site
like it owes you money.
Uptime monitoring, TLS handshake analysis, and instant Slack notifications. Simple to deploy, powered by Supabase, and monetization-ready via Freemius.
Heartbeat Monitoring
Pings websites at custom intervals (down to 60 seconds). Calculates latency metrics and records complete history in PostgreSQL.
TLS/SSL Expiry Sync
No more random numbers. Connects directly to the TLS socket to parse actual certificate validity parameters and countdown warnings.
Slack & Email Alerts
Monitors state transitions. Instantly dispatches customized Neobrutalist blocks to your Slack channel and email logs on incident change.
Uptime monitoring is cheap. Trust is earned.
Why web agencies trust GuardianNode to keep their client portals secure and online.
Tenant Isolation (Supabase RLS)
We enforce PostgreSQL Row Level Security (RLS) on all database tables. Your alert configurations, API channels, and check histories are fully isolated in the cloud instance.
Obsolete TLS Protocol Scanning
We run automated audits targeting SSLv3, TLS 1.0, and TLS 1.1 handshake attempts. Know immediately if legacy configurations leave your users exposed to negotiate downgrade hacks.
Sustainability Carbon Footprint
We analyze total payload sizes (KB weight) and query green power registries to estimate CO2 emissions per visitor. Keep client projects eco-friendly and lightning fast.
Zero External API Dependencies
Every nameserver query, WHOIS registry check, sitemap lookup, and redirect tracking hop executes directly on our server nodes. Keep client domains secure, performant, and fully independent.
How the watchtower monitors your digital footprint.
A continuous four-stage diagnostics feedback loop engineered to verify status, detect vulnerabilities, and fire instant alerting webhooks.
Endpoint Heartbeat
Our distributed system schedules HTTP/HTTPS GET requests at custom intervals to test your target URL. We parse response status codes, redirect counts, and resolve raw TCP latency down to the millisecond.
Security Audit Scans
We perform connection handshakes to scan for obsolete TLS protocols and analyze returned HTTP response headers, verifying that Content Security Policies and HSTS directives are configured correctly.
DNS & propagation
We parse your nameserver mappings, validating MX records and checking critical TXT parameters (SPF, DKIM, DMARC) to guarantee domain authentication and prevent brand impersonation.
Immediate Alerts
When a probe failure occurs across consensus regions, we format and dispatch instant notifications directly to your Slack channels, Discord webhooks, or technical support logs.
The Business Value of Edge Diagnostics
Most website downtime monitoring services check only whether your server responds with an HTTP status code. But modern web operations are far more complex. A page might return a status code of 200 while displaying a completely blank white screen due to a frontend Javascript error. Alternatively, your homepage might load fine while your checkout system fails silently due to a nameserver routing problem or expired security credentials.
GuardianNode addresses these blind spots by auditing the entire operational footprint of your site. We monitor page latency trends, verify certificate validity countdowns, inspect HTTP security headers, and analyze total asset payload sizes to track digital sustainability. By keeping tabs on all of these parameters in a single, unified watchtower console, digital agencies and web administrators can proactively fix errors before they impact search rankings, conversion metrics, or customer trust.
