What is SSL Monitor?
SSL Monitor is a free unified SaaS dashboard built for web agencies and IT teams. It automatically checks your SSL certificates, domain registrations, hosting renewals, and professional email expiry dates — consolidating what used to require multiple manual spreadsheet checks into a single automated system accessible from any device.
What Problems Does It Solve?
Managing 10+ client websites manually is error-prone. SSL Monitor automates daily certificate checks via live socket handshakes, calculates expiry countdowns precisely, sends direct alert emails to your inbox, and maintains a real-time health dashboard — all without you ever having to open a browser to check each domain manually.

SSL Monitor & Domain Manager is a free SaaS platform built for web agencies and professionals. It automatically monitors SSL certificate expiry, domain registration renewal dates, hosting deadlines, and professional email account expiry — all in one unified dashboard with automated email alerts.
The system initiates a secure socket stream handshake to port 443 of each monitored domain daily. It retrieves the peer SSL certificate data using PHP's OpenSSL stream context wrappers, extracting the certificate issuer, issue date, and expiration timestamp. The days remaining are calculated and status indicators updated in real time.
After completing the registration form, your account enters a pending review state. A notification email is automatically dispatched to the system administrator. Once reviewed and approved, you will receive an automated confirmation email and can immediately log in to your dashboard.
