What is the Difference Between VLAN and VPN?

🆚 Go to Comparative Table 🆚

VLAN (Virtual Local Area Network) and VPN (Virtual Private Network) are two different technologies used for different purposes within a network. Here are the main differences between them:

VLAN:

  1. Focuses on organizing and segregating devices within a network.
  2. Creates virtual zones in a shared space, allowing multiple networks within one physical network.
  3. Does not offer encryption, which makes it unsuitable for public networks.
  4. Primarily used for segmenting traffic and improving network administration within a local area network.

VPN:

  1. Creates secure connections over the internet for data privacy and content access.
  2. Establishes encrypted (protected) connections between devices and networks, ensuring data privacy while traveling online.
  3. Provides an extra layer of security for accessing resources within a VLAN, keeping data private.
  4. Connects remote employees to their company's network and resources through VPNs, allowing secure access to the network over a public network like the internet.

In summary, VLAN is a method for organizing and segregating devices within a network, while VPN is a technology used to establish secure connections over the internet for data privacy and content access. VPN can also provide additional security when accessing resources within a VLAN, making it a suitable choice for remote workers or users who need to access sensitive information on public networks.

    VLAN and VPN are two independent technologies in computer networking that serve different purposes. Here is a table comparing the differences between them:

    Feature VLAN (Virtual Local Area Network) VPN (Virtual Private Network)
    Traffic Scope Local network Remote network
    Communication Devices within a VLAN can communicate with each other; communication between VLANs requires routing or Layer 3 switches. Users can securely access the private network remotely. VPN enables communication with devices and resources on the remote network.
    Anonymity Does not provide anonymity for network traffic. Can provide anonymity by hiding the user's IP address and location while accessing the Internet.
    Purpose Logically segmenting and managing network traffic within a physical network architecture. Connecting authorized users to corporate network resources through a secure, encrypted connection established over a public network (such as the Internet).
    Security Offers more security because users can only access resources necessary for their jobs. Remote VPNs usually allow access to all resources, but more divided access options are available.
    Limitations VLANs create separate digital spaces within physical networks. Devices in the same VLAN can communicate with each other if the network administrators have allowed it. A VPN is used to securely connect remote users or networks over the internet.

    In summary, a VLAN is used to segment a local network for improved management and traffic control, while a VPN is used to securely connect remote users or networks over the internet.
