SSL Lookup: A Complete Guide for Website Security

When browsing the internet, you’ve likely noticed a small padlock icon next to website addresses. That icon represents an SSL certificate—a critical tool for online security. An SSL lookup is the process of checking and verifying those certificates to ensure a website is secure. This guide explains what SSL lookup is, why it matters, and how you can use it to protect your online presence.

An SSL lookup allows you to check the details of a website’s SSL certificate, including:

Certificate issuer

Expiration date
