SSL checks without the terminal

SSL Finder is a PowerShell-based tool with a clean GUI overlay — all the power of PowerShell certificate checking, none of the command-line friction.

🔍

Full certificate details

Get the complete picture on any certificate — issuer, subject, serial number, validity dates, and signature algorithm. Everything in one screen.

Expiry tracking

See exactly how many days remain on any certificate. SSL Finder flags expiring-soon certificates with warnings so you’re never caught off guard.

🖥️

Clean GUI — no CLI needed

Built for IT teams who don’t want to dig through PowerShell syntax every time. Just enter a domain and scan. Results are presented cleanly, not as raw terminal output.
