Frequently Asked Questions
What is SSL certificate monitoring?
SSL certificate monitoring automatically checks your domain's SSL certificate validity and expiration date. AlertSleep alerts you 30, 14, and 7 days before expiration so you can renew before your site shows browser security warnings.
How far in advance will I get SSL expiry alerts?
AlertSleep sends alerts at configurable intervals — by default 30 days, 14 days, and 7 days before your SSL certificate expires. You can customize these thresholds in your monitor settings.
Does AlertSleep monitor SSL for multiple domains?
Yes. You can monitor SSL certificates for as many domains as your plan allows. Each domain is checked separately with its own expiry tracking and alert configuration.
What happens if my SSL certificate expires?
An expired SSL certificate causes browsers to show a security warning page, blocking visitors from accessing your site. Google also penalizes sites with SSL issues in search rankings. AlertSleep ensures you're warned well in advance.
Can AlertSleep detect misconfigured SSL certificates?
Yes. In addition to expiry tracking, AlertSleep checks for common SSL issues including self-signed certificates, domain mismatch, incomplete certificate chains, and deprecated protocols (SSL 3.0, TLS 1.0).
