All You Need to Know about Proxy Servers and Cybersecurity
Proxy servers are fundamentally used to hide the IP address of a client from the internet. A proxy server takes the form of an agent, which then takes a client’s request and passes it to the internet destination and vice versa.To get more news about

When connected to a proxy server, traffic uses the server’s IP address, and not the client’s. Proxy servers help hide users who are typical targets for malware attacks. This often includes CEOs, board members, division leads, and IT professionals. These individuals are usually targets because they have the authority to escalate permissions. They also have access to sensitive data.
What Is a Proxy Server?
Proxy servers work at the network’s perimeter behind the exterior firewall to relay data between network users and the internet. Their primary goal is to hide an end-user’s IP from the Internet, making it harder to target key people of an organization. Hiding the IP addresses of clients is called network address translation (NAT). Often, firewalls and routers perform this NAT function.
Proxy servers can act as a caching mechanism to speed up transactions, reduce network traffic, and improve performance. They do this by holding previously requested content locally. This data is only replaced if it doesn’t meet the specific request by the end-user.
In addition to that, you can use proxy servers to also control traffic, both inbound and outbound. Most firewalls, such as those from Norton and Bitdefender, also have this IP filtering function. In general, look for fourth-generation or higher firewalls. These often ship with IP filtering and other useful administrative capabilities.
Moreover, logging traffic can be very useful for networks that need to meet specific security audit requirements or de-facto industrial standards.
Lastly, you can even use proxy servers to bypass a firewall. For instance, a user in a local area network (LAN) may wish to check a blocked IP address like Twitter or another social media website. To get around this, that user might install a proxy server at home that they can connect to and access the blocked website. In this case, you can also use a VPN, but proxy servers give owners access to their own network and content remotely.
