Buying a proxy provides better security, privacy, and anonymity when browsing the internet. It also helps with bypassing geo-restrictions, protecting your identity, and avoiding online tracking.

Proxies typically do not speed up browsing. However, certain proxies, like caching proxies, can speed up access to frequently visited websites by storing copies of data, thus reducing load times.

Free proxies often come with security risks, such as lack of encryption, data leaks, and poor performance. They may also log your activity and sell your data to third parties.

Proxies allow businesses to scrape data from websites without being blocked or detected. Using a large pool of rotating proxies helps avoid IP bans and ensures uninterrupted access to the target website.
