When asking visitors for sensitive data, it's important that you encrypt communication from the visitor to your servers. The industry-standard method of encrypting this data is called SSL, or Secure Socket Layers.
When you install SSL, sensitive data such as passwords and credit card numbers essentially becomes locked and can only be unlocked by the intended recipient. The encryption technology of SSL helps to prevent hackers from being able to steal the data.
In a world where data breaches are on the rise, and consumers are abandoning carts when they feel their personal data is at risk, it’s never been more essential for ecommerce businesses to secure their sites with SSL.
