SSL Monitoring for APIs and Websites
Prevent avoidable outages by monitoring certificate expiration, trust validity, and HTTPS behavior. SiteInformant gives engineering teams early signal and clean data before certificate issues impact users.
Production-focused monitoring for DevOps, platform, and engineering teams.
Catch failures early
Find certificate risks before renewal deadlines become incidents.
Unify SSL + uptime checks
Use one workflow for HTTPS reliability and endpoint availability.
Route alerts clearly
Send actionable notifications to the teams that own the endpoint.
Why SSL monitoring still fails
Most SSL incidents are not caused by missing tools. They happen because checks are fragmented, ownership is unclear, and teams find out too late.
SiteInformant combines certificate health and endpoint availability so teams can act before downtime reaches customers.
What you can monitor
Certificate expiration timing
Track days-to-expiry and alert before renewal windows close.
Validity and trust status
Detect invalid chains, trust issues, and broken certificate states.
HTTPS handshake behavior
Verify endpoints respond correctly over TLS in real checks.
Reliability context
Correlate SSL issues with uptime and response-time patterns.
How it works
1. Configure endpoints
Add critical website and API URLs with ownership context.
2. Run continuous checks
SiteInformant evaluates SSL posture and uptime on a recurring schedule.
3. Alert early and act fast
Get actionable notifications before expiration and before outages escalate.
Common use cases
API platform teams
Protect customer-facing endpoints where certificate failures break integrations.
SaaS engineering teams
Prevent expiration-driven outages across production domains and subdomains.
Agencies managing many properties
Standardize SSL and uptime checks across multiple client environments.
Internal service owners
Monitor internal APIs where silent certificate failures block dependencies.
