What is SSL and why do I need it?

SSL (Secure Sockets Layer) is an encryption technology that creates an encrypted connection between a web server and a web browser, allowing private information to be transmitted without eavesdropping, data tampering, and message forgery.

SSL protects credit card numbers and other sensitive information from malicious third-parties. It also protects your site from malware and prevents others from injecting advertisements into your resources. An SSL certificate is recommended for every website to protect user privacy and prevent tampering.

What to look for in an SSL Provider

  • Product features - Does the certificate authority provide a certificate with the features you need?
  • Support - Does the certificate authority offer quality customer support when you need it?
  • Price - Is the certificate within your price range?

Getting started with SSL

  1. Determine the features you need. Will customers trust you more with an OV or EV certificate?
  2. Determine your budget. Certificates range from $0 to thousands of dollars.
  3. Evaluate providers. Read certificate provider reviews from real customers.
  4. Buy and install certificate. After purchase, install it on your web server.
