Transfer an SSL to Ubuntu 16.04 or CentOS 7

Reading Time: 7 minutesSSL certificates have become a de facto part of every website. If you don’t yet have an SSL on your site to encrypt data, you should. Rather than showing an extra layer of security on sites protected by SSL, modern browsers instead now display a warning when a website does not have an SSL, essentially requiring sites to maintain their positive image.

How to Configure Your Liquid Web VPN

Reading Time: 2 minutesLiquid Web offers a free Virtual Private Network (VPN) user with every account. A VPN uses encryption to secure your computer’s connection to the Internet and guarantees that all of the data you’re sending and receiving to the Liquid Web network is secured from any potential prying third parties.

Be security-minded.

A VPN will secure and encrypt inherently insecure communications (such as HTTP, FTP, SMTP, etc.) to the Liquid Web network, even while using an untrusted public network.

Who uses a VPN? People just like you.

The Professional: Whether working from a permanent home office, or simply getting a few important projects done from home, a VPN will provide secure access to files stored on your dedicated server.

Remote Developers: Do you have a remote fleet of WordPress, Joomla, PHP, Drupal, or other CMS’s that need secure access to a dedicated server on your hosting infrastructure? If so, a VPN is not only perfect, but should be required.

The World Traveler: Working on your top secret startup from abroad? Or perhaps uploading photos from your most recent adventure? Prevent snooping by using a VPN.

Once you’re logged into your Liquid Web Manage account, follow the steps below to create a VPN user and get connected! Continue reading “How to Configure Your Liquid Web VPN”
