Stop Losing Sleep Over Client SSL Outages.
Start Monetizing Infrastructure Care.
Never let an expired certificate or broken intermediate bundle trigger an angry client call. Organize client domains into branded portfolios, route alerts cleanly, and generate automated white-label security reports that justify your monthly maintenance retainers.
Engineered Exclusively for Multi-Client Operations
Standard uptime checkers ping homepages. CertificateGuardian audits the cryptographic foundation of your client roster.
Never Get Caught by a Broken Chain Again
Standard ping monitors miss incomplete intermediate bundles that silently break mobile apps, checkout webhooks, and third-party APIs. We verify the complete certificate handshake from multiple geographic edge regions every hour.
Turn Monitoring into Billable Client Value
Stop treating monitoring as an internal overhead expense. With white-label PDF security audits branded with your agency’s logo and colors, you have tangible, client-ready deliverables to bundle into high-margin $99–$250/month maintenance packages.
Clean Multi-Tenant Routing
Keep client notifications strictly isolated. Send Client A’s renewal alerts directly to their designated Slack channel or contact email without exposing other clients in your roster or flooding your internal team channels.
