Types of secure connection

  • SSL (Secure Socket Layer). SSL and its successor, TLS (Transport Layer Security) are cryptographic protocols that protect the communication over the internet.
  • VPN (virtual private network). A VPN encrypts a user’s connection to the internet and routes it via one of their servers. VPNs can use different protocols, such as OpenVPN or NordLynx, to make the connection secure.
  • SSH (Secure Shell). SSH is used by administrators and developers to secure a connection between two or more network devices. It is often used to connect to remote devices securely.
  • IPSec (Internet Protocol Security). IPSec is a set of protocols used to secure communication over the internet. It’s valued for providing confidentiality, integrity, and data authenticity.
  • SFTP (Secure File Transfer Protocol). SFTP is a secure version of its predecessor, FTP. It is used to transfer sensitive files over the internet.
  • HTTPS (Hypertext Transfer Protocol Secure). HTTPS provides encrypted communication between the web servers and the client, or, in other words, protects your connection to websites you visit. You can know your connection is secure by the padlock next to the website’s address.
