The Business & Security Impact of Expired SSL
- Downtime and Financial Loss: E-commerce sales stop instantly when checkout pages trigger certificate warnings.
- Brand Trust Degradation: Ziyaretçiler siteyi güvenilmez bulup hızlıca terk eder.

Crucial Steps to Take Before Expiry
1. Map Your Certificate Footprint: Determine every domain and subdomain running HTTPS. 2. Automate Renewals: Use tools like Let's Encrypt with automated scripts (Certbot) to auto-renew every 90 days. 3. Monitor Expiration Dates: Set up external scanners to warn you 30, 14, and 7 days prior to expiry.
