You have just set up your openedx instance. Congratulations! But, the work is not done yet: you need to protect it with security information like an SSL certificate which will encrypt and decrypt all of that data in transit between the user's browser and our servers. This ensures only encrypted traffic passes for anyone trying to listen on any network along its way from their device through Wi-Fi or cellular networks to us, so they are always safe when using this site without risking personal identity theft or fraud.
