What is the difference between vpn and proxy

Both VPNs and proxies are common tools on the Internet that are used to hide a user's real IP address and provide a more secure network connection. While they have some similarities, there are also some important differences.

1. VPN (Virtual Private Network):

VPN protects the privacy and security of data transmission by establishing an encrypted channel between the user device and the target server.

• A VPN can route all of a user's network traffic to a remote server so that the user's IP address is replaced with the IP address of the server's location.
• VPNs can provide more advanced security, such as end-to-end encryption and firewall protection.
• VPNs usually come in the form of software or applications that need to be installed and configured on the device.

2. Agent:

A proxy server acts as an intermediary between the user and the target website, hiding the user's true IP address by forwarding requests and responses.

• The proxy will only send and receive specific network requests on behalf of the user and will not affect other network traffic.
• The proxy can choose an anonymous proxy or a transparent proxy according to the user's needs, but the security is relatively low.
• The proxy is usually provided as a server address and port, and the user can configure the proxy in the network settings.

3. Main differences:

VPNs provide more comprehensive privacy and security, encrypting all network traffic and protecting users' identities. Proxies only provide anonymity on specific requests.

• A VPN changes a user's global network connection, while a proxy only changes network settings within a specific application or browser.
• Proxies are generally fast and easy to set up and use. VPNs may cause some lag, but provide more advanced security.

Choose the right tool to protect privacy and security based on your individual needs. If you need more comprehensive protection and change your entire network connection, a VPN is a good choice. If you only need to hide your IP address from a specific application or browser, a proxy may be more suitable.
