VPN vs. VLAN: Key Differences – Quick Look
VPN is a tool that establishes an encrypted connection across both ends, ensuring your privacy while browsing the internet. It is one of the most common tools people use to guard their privacy.
On the other hand, VLAN specializes in organizing or separating the networks digitally, no matter if they are physically connected.
Here’s a quick look at these two various technologies:
| Features | VPN (Virtual Private Network) | VLAN (Virtual Local Area Network) |
|---|---|---|
| Purpose | Safeguard users and their privacy while using the internet | Dividing physically connected networks into digital subnetworks |
| Scope | Provides 3 layers of protection | Provides 2 layers of protection |
| Segmentation | It helps users and remote networks to connect | Only separate networks locally |
| Communication | Allows communication across various networks remotely | Between a single physically connected network |
| Isolation | Encrypts data over a public Wi-Fi network | Isolates communication between physically connected networks |
| Security | Enhances security by encrypting your data and providing anonymous access to the internet | Lacks in providing higher security benefits and only guards you within a local network |
| Traffic Control | Routes all the traffic through encrypted tunnels | Allows users to control or limit traffic within a similar VLAN |
| Configuration | Involves VPN server and client configuration | Requires configuration of VLAN switches |
| Addressing | VPN uses the server’s IP addresses to route the traffic and hide identification | VLAN uses MAC addresses for segmentation |
| Devices | Use for devices at remote locations | Use for devices available within the same physical location |
| Application | Offer high-end encryption to ensure your data is secure | VLAN doesn’t offer encryption |
| Accessibility | Accessible on devices connected with the same local network | Communicate on the devices directly connected with the VLAN |
| Scalability | Scalable on a wide variety of networks | Limited to a specific infrastructure |
VPN vs. VLAN: Key Difference – In Detail
Individuals and organizations use VPNs and VLANs to optimize network security and control traffic. However, both are different technologies, and their difference is evident. Below we explained the major difference between both tools in detail.
Purpose
Organizations and individuals use VLAN to organize devices separately for better communication among devices and traffic control. However, a VPN lets authorized employees and users connect with the organization’s network.
Scope
VLAN resides at the data link layer 2 of the OSI model, whereas VPN belongs to layer 3 of the OSI model.
Segmentation
VPN connects users through a particular encrypted tunnel or with remote networks. In contrast, VLAN separates devices within a LAN to control and organize the traffic and enhance the communication between devices.
Security
People mostly use VPNs because of their security features. They provide end-to-end data encryption, anonymous browsing, and more, protecting users from cyberattacks.
On the other hand, VLAN offers limited privacy & security features within a local area network. However, network administrators can easily modify it for network traffic or security reasons.
Configuration
VPN involves client and server configuration, which is necessary because they must connect the user’s device to the particular server. In comparison, VLAN only requires configuration on the network switch.
Accessibility
You can access a network using a VPN from anywhere, but ensure your device is connected to the internet. As noted above, VLAN is available within the local area network, so devices connected with the same VLAN can only communicate directly.
Scalability
VLAN scalability is limited to a specific network infrastructure. However, with a VPN, you can effortlessly access any private network or internet from anywhere while keeping you secure over the internet.
What is a VPN?
A Virtual Private Network (VPN) is a widely used tool for digital security that creates a private tunnel that provides end-to-end encryption between the remote device and the internet. It ensures that your data is safe and you are accessing the internet without showing your identity.
Moreover, a VPN helps users bypass geo-restrictions, censorship, proxies, and other restrictions without hassle and enjoy the internet freely – without showing their identity.
The world’s first business VPN was initially launched in 1996. Since then, the industry has evolved, and many other vendors have come into being, providing security for personal and business requirements. These VPNs provide high-end protection to secure the users’ or organizations’ data from third parties.
Unfortunately, many VPNs don’t offer features for personal and business security. But ExtremeVPN tops the list in providing robust security & privacy features for both personal and business use. It offers AES 256-bit high-end encryption, a no-logs policy, P2P file sharing, multiple fast-speed servers, and up to 10 simultaneous connections.
How Does a VPN Work?
After connecting your device to the internet, there’s always a major risk of data and privacy breaches while sending and receiving data. To keep the user and their data safe, IT experts made a software called VPN. Connecting to a VPN’s server creates a virtual private tunnel that encrypts your data and ensures security.
High-end VPNs like ExtremeVPN provide robust encryption that hackers cannot crack. It also changes your IP address and masks it with the IP address of the server you are connected to, providing anonymous browsing to its users. In addition, you can control your internet traffic and select VPN apps using ExtremeVPN’s split tunneling feature.

We hope you have gained enough knowledge regarding VPNs and are now ready to learn about VLAN. You might be thinking, “Is VLAN similar to a VPN?” The answer is No. Let’s discuss why.
What is VLAN and How Does it Work?
VLAN stands for Virtual Local Area Network. It acts as a digital separator that separates physically connected devices in a larger network. It helps organizations to divide physically connected devices into groups to manage things smoothly.
VLAN enhances the security, management, and efficiency of a network.
Working Procedure of a VLAN
VLAN provides services by creating a digital fence in your network, making separate groups, and providing security.
Suppose you own a building with multiple floors, each with several rooms. Each room contains employees of various departments. You want to separate the departments for security, communication, and management reasons. To perform this, you need a VLAN.
A VLAN will create separate digital fences or spaces for each department within a network. The devices within a similar group can easily communicate with each other like they are all in the same room. However, devices from other groups can’t communicate with this group without doing some technical changes.
Does VLAN Encrypt the User’s Data?
No, VLANs don’t provide any kind of data encryption. The tool separates devices connected within a physical network into various groups for better traffic control and security. Therefore, it doesn’t offer encryption. However, subscribe to a top-notch VPN like ExtremeVPN to encrypt your data.
Uses of VLAN
Below are the major uses of a VLAN:
- Organizing Devices: This tool creates digital fences that divide a big physical network into small groups for better communication and smooth management.
- Reducing Congestion: Each VLAN contains devices of a particular group, resulting in low traffic, and works like a network.
- Guest Access: VLAN provides security by creating a different network for guests. It helps the organization to keep the guests away from the internal confidential stuff.
- Security: Creating separate groups helps prevent unauthorized access to confidential data.
- Fair Sharing: VLAN distributes a particular network’s resources equally among all the devices within that network.
- Quality Control: Creating various groups for specific networks helps in smooth communication.
Using a VLAN in a home or organization helps you control traffic from various network devices. This enhances security communication and makes things easy to manage. Let’s discuss some more uses of VLAN.
VLAN in Home Setting
VLAN also helps in a home where parents, guests, and children use the internet through the same network. You can set up VLAN in this way:
- Parent VLAN: This VLAN separates devices, including parents’ personal and office devices (laptops, desktops, etc.). The VLAN must offer strict security features to keep sensitive information separate from the children and guests.
- Children’s VLAN: It separates devices used by children, including smartphones, tablets, gaming consoles, laptops, and more. This VLAN should offer settings for time restriction and web content filtering to ensure kids are not using the internet.
- Guest VLAN: When guests visit your house, they can connect their device with the guest VLAN. It will let them access the internet, but they can’t access the devices of children and parents’ VLANs. That’s how VLAN can provide you security in a home network.
VLAN in a Work Setting
This tool does the same job in a work setting as in a home network. For example, two teams are sitting in the same room – one from the sales department and the other from the software development department. Both teams are a part of the same network, but we can use VLAN to secure so they can operate independently, providing better security and reducing congestion.
Pros of VLAN
- Better Network Organization: Using VLAN, you can separate devices into their appropriate groups, helping in communication, security, and traffic control.
- Optimized Performance: They ensure that users can communicate easily like they are in the same room.
- Enhanced Privacy: VLANs separate the networks, which enhances privacy because the other VLAN devices cannot interfere without permission.
- Cost-effective: VLAN removes the need for making separate networks using extra physical equipment. It does all the job and provides security while saving you a few bucks.
Cons of VLAN
- Hard to Setup: Setting up a VLAN is a difficult job that requires you to be a tech expert.
- Security Concerns: If you make a mistake while setting up a VLAN, it will lead to a security and privacy threat because the devices within the same VLAN will access other device’s data.
- Extra Effort: Configuring and managing a VLAN requires time and extra effort.
- Scaling Limitations: Managing many VLANs can be less efficient and overwhelming if you have a huge physical network.
VPN vs. VLAN: Problems and Their Solutions
Both tools are undoubtedly helpful and are good in their own way. However, everything has some pros and cons. Similarly, VPN and VLAN have some problems, but you can fix them whenever you face them.
Common VPN Problems and Their Solutions
- VPN is too Slow: If you face this problem, try connecting to another VPN server, or reducing internet activity may also solve it. However, if you still face this issue, the problem is not with your VPN; it’s your internet connection. Test your internet connection speed and change the internet network for a better speed.
- VPN isn’t Masking Your IP Address: If your personal VPN doesn’t mask your IP address, change the VPN protocol, which might solve the problem. However, if the issue persists, we recommend you change your VPN and subscribe to a high-end VPN like ExtremeVPN.
- VPN isn’t Connecting: Users usually face this problem when they have a problem with their internet connection. Ensure you have a strong internet connection by testing the internet connection speed. Check for VPN app updates if you are still encountering the same issue. If the above methods don’t work, uninstall all the VPN apps from your device and reinstall the VPN app. Otherwise, contact the VPN’s customer support; they will help you to solve this problem.
Common VLAN Problems and Their Solutions
- VLAN Mismatch: This problem occurs when the same switch interface of a VLAN is configured with the other VLANs. A critical factor in determining the local VLAN mismatch is the trunking mode of the two ports. However, its solution is as simple as configuring a VLAN on all the network interfaces to redirect the traffic towards a single VLAN.
- Missing VLAN: Each has a specific port to make it a part of the network. But, sometimes, the switch becomes inactive and shows the missing VLAN problem. But fear not, you can easily resolve this problem using the “show VLAN” command. It will display all the available VLANs, and you can check which VLAN is missing or inactive.
- Problems with Physical Connections: VLANs contain physical connectors and some virtual components, which sometimes cause connection problems. However, verifying the LED light on the physical switch can ensure that the first connection layer is in good shape. If the light is blinking, it’s a green flag. The second step is to check the cables and their physical connection. If the cable or network card is damaged, replace it with a new one and verify if the issue persists. If yes, then you should consult a VLAN repair professional.
