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.
