Differences Between VPN And VLAN

Parameter of ComparisonVLANVPN
Full FormVirtual Local Area Network (VLAN)Virtual Private Network (VPN)
  TypesType of VLAN:
1. Port-based VLAN
2. Protocol-based VLAN
3. MAC-based VLAN
Type of VPN:
1. Remote Access VPN
2. Site-to-Site VPN
Kind of serviceVLANs are the kind of subnetworksVPNs are the technology a service
Take help ofVLANs use virtual LANs to segment trafficVPN uses encryption to create a virtual private network
PurposeHelp in connecting multiple devices that are separated by distanceHelp in connecting authorization personals
hierarchical structureVLAN is a subset of the VPNVPN is a superset of VLAN
Definitionuse to consolidate(or strong) devices that are separated, into a single Broadcast Domainuse to transmit secure data
Tunnel/channelVLAN does not use any kind of tunnelVPN uses a virtual tunnel for secure connection
Securityless secure as compared to VPNmore secure
PriceVLANs are cheapVPNs are expansive
Efficiency VLAN is less efficient as compared to the VPNVPN increases the efficiency

Similarities Between VPN And VLAN

Despite being so many differences between VLAN and VPN, there are multiple similarities between them, 

  • In terms of network scalability both VPN and VLAN allow multiple institutes and corporates to maintain their webbing more effectively.
  • VPN and VLAN both can be used to enhance privacy or security by encrypting the network traffic.
  • VPN and VLAN can be used to improve network security.
  • As far as route traffic is concerned both VPN and VLAN use IP addresses.
  • Within the physical network layer VPN and VLAN both are used to create independent virtual networks.
  • Both are used to save the cost of the different institutes and corporations by reducing the need for physical network components

What is VLAN?

  • It is a collection of the same type of devices/departments in one or more local areas. Designed to interact with each other through data links as they share the same physical location in the same broadcast domain.
  • VLAN behaves like an independent LAN.
  • VLANs are represented by a number which is called VLAN ID, which is different and unique.
  • It is also possible to divide one large physical LAN into two smaller logical LANs. Sometimes, the layout of the network equipment does not match the organization’s structure. 

For example,

the engineering and finance departments of a company might have computers on the same physical LAN because they are in the same wing of the building but it might be easier to manage the system if engineering and finance logically each had its own network Virtual LAN or VLAN.

What is Virtual Private Network (VPN)?

  • VPN is a service that helps you stay private when you are online. it protects network connection while using public networks.
  • VPNs use encryption techniques to encrypt your internet traffic data such as IP address and hide your online identity over the internet. VPN makes a secure tunnel for your device to connect to the internet.
  • To use VPN you need to install the software-based technology known as the VPN client on your device that would let you establish a secure connection.

How VPN functions

  •  The VPN client connects to the Wi-Fi and then to the ISP(Internet Service Provider) here VPN client encrypts your information/data by using VPN protocols, data is encrypted to make sure it is secure.
  • Next, the VPN client establishes a VPN tunnel within the public network that connects to the VPN server the VPN tunnel protects your information from being intercepted by the hacker, and your IP address and the actual location are changed at the VPN server to enable a private and secure connection.
  •  Finally, the VPN server connects to your website server in the last step where the encrypted message is decrypted, in this way your original IP address is hidden by the VPN, and the VPN tunnel protects your data from being hacked.
  •  In this manner, your data is anonymous and secure when it passes through the public network and that makes a difference between a normal connection and a VPN connection.
