1. What is a proxy server and why do you need a proxy server when working remotely

The function of a proxy server is to obtain network information on behalf of network users. Figuratively speaking, it is a transfer station for network information and an intermediate agency between personal networks and Internet service providers. It is responsible for forwarding legal network information and controlling and registering forwarding.

As a bridge connecting the Internet and the Internet (intranet), the proxy server plays an extremely important role in practical applications. It can be used for multiple purposes. The most basic function is connection. In addition, it also includes security, caching, content filtering, access control management and other functions. More importantly, the proxy server is an important security function provided by the Internet link-level gateway. Its work is mainly in the session layer of the Open System Interconnection (OSI) model.

Proxy servers can not only improve browsing speed and efficiency, but also implement network security filtering, traffic control, user management and other functions. Therefore, it is not only a network firewall technology, but also can solve the problem of insufficient IP addresses caused by many units connecting to the Internet.

2. Benefits of using proxy servers for remote workers

One IP address or Internet account is used by multiple users at the same time

Under the current circumstances, IP addresses are limited and valuable resources in the Internet. If these IP addresses are only used for a single user requesting Internet access, it can be said to be a waste of resources. Using a proxy server can provide Internet access to multiple users at the same time through one IP. For internal networks connected to the Internet through dial-up, it can be achieved by using one telephone line, a modem and an Internet account to allow all users on the internal network to access the Internet at the same time, thus making full use of IP address resources

Cache function can reduce costs and increase speed

During installation, the proxy server will open a disk space on the hard disk as a cache area, download a copy of the content received by the proxy user from the Internet and save it. When another user accesses the same content, it will be directly transmitted to the user from the cache area instead of searching from the Internet. This function of the proxy server can greatly improve the access speed and reduce the communication cost, which is a very important function.

Manage the permissions and information flow billing of internal network users

Through the proxy server, network administrators can easily manage the access rights and information flow billing of internal network users when providing Internet services. Network administrators can not only allow only authorized LAN users to access the Internet, but also control the time and type of Internet services these users access using which computer. For users who have been allowed to access the Internet, network administrators can also manage the billing of information flow in a variety of ways, such as: billing according to individuals, billing according to computers belonging to departments, etc., which brings great convenience to network management.

Monitor and filter Internet information entering the internal network

In order to avoid information that is not related to the business from entering the internal network and wasting communication fees, various institutions often have some corresponding regulations on the content that is allowed to be accessed. Through the proxy server, network administrators can not only use filtering methods to simply control the content of information flowing from the Internet to the internal network, but also monitor the user's access to the Internet in real time and establish monitoring logs for archiving.

3. What are the functions of proxy servers as intermediaries?

As intermediaries in the online world, proxy servers play a much more important role than the above points. It can also help remote workers:

Save bandwidth: Reduce data transmission and bandwidth consumption by compressing data, caching commonly used content, etc.

Anonymous browsing: Hide the user's true identity and browsing habits to protect personal privacy.

Prevent DDoS attacks: As a buffer for the target server, the proxy server can filter out malicious traffic and protect users from network attacks such as DDoS.

4. PIA S5 Proxy is recommended for remote workers

Among many proxy server providers, PIA S5 Proxy stands out for its excellent performance, rich features and good reputation, becoming the first choice for remote workers. PIA S5 Proxy not only supports HTTP(S), SOCKS5 protocol, 350 million+ high-speed and stable residential IPs to ensure stable connections, but also has 100% private residential IPs and top encryption technology to protect your privacy and security.
