1.Safety. Basically, an agent acts as an intermediary between the user and the network. They mask users' IP addresses (and, in some cases, their online activities). This is a key feature because it prevents malicious actors from accessing your confidential information (such as credit card details). Therefore, proxies can provide an additional layer of security. In addition, asking for a user's IP address is associated with the added benefit of anonymity.
2. Performance. Some proxy servers can be set up for load balancing to manage part of your Web traffic load.
But not all proxy servers can improve Web performance. On the contrary, most of them will actually reduce it because they add an extra packet transmission phase.
If you need multiple different proxy IP, we recommend using RoxLabs proxy：www.roxlabs.io
