Check Website SSL

What is an SSL Certificate?

An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. TLS (Transport Layer Security) is the updated, more secure version of SSL.

SSL certificates are vital for:

  • Encryption: Protecting data (like passwords and credit card numbers) transferred between the user and the server.
  • Authentication: Proving that the website is owned and operated by the expected entity.
  • Trust: Showing the "padlock" icon in the browser, signaling to users that the site is safe.
  • SEO: Google gives a ranking boost to websites that use HTTPS.
