Difference between a VLAN and VPN?

  • A VLAN helps to group workstations that are not within the same locations into the same broadcast domain and VPN is related to remote access to the network of a company.
  •  VLAN is a subcategory of VPN and VPN is a means of creating a secured network for safe data transmission.
  • A VLAN is basically a means to logically segregate networks without physically segregating them with various switches. A VPN is used to connect two points in a secured and encrypted tunnel.
  • A VPN saves the data from prying eyes while in transit and no one on the net can capture the packets and read the data. VLAN does not involve any encryption technique but it is only used to slice up your logical network into different sections for the purpose of management and security.
  • VLAN is generally used when it is necessary for a person to connect with someone whom you cannot connect from outside the VLAN. It requires a special permission before access. Vlan VPN is used to communicate in a secured manner in an unsecured environment.
