Surfshark is a virtual private network (VPN) service that enables users to alter the origin of their internet connection by routing their traffic through Surfshark's servers. This process changes the IP address that websites see from the user’s original IP to one assigned by Surfshark. Think of it like entering a building through a different door—this can help users avoid exposing their real IP address on public networks, reduce tracking, simulate a connection from another country, access region-specific content, and secure data as it travels between the user’s device and the Surfshark server. One of Surfshark’s features is IP address rotation, which changes the visible IP address periodically during a session. This can help reduce the risk of being tracked based solely on an IP address. However, it does not erase a user's entire digital identity. Online services can still identify users through cookies, browser characteristics, and online behavior, which are not affected by IP rotation. Surfshark also includes a Bypasser function, which allows users to choose which apps or websites use the VPN and which use the regular internet connection. This selective routing can be useful in scenarios like keeping a banking app on the standard connection while using the Surfshark server for browsing, thereby balancing security with convenience. Public Wi-Fi networks in places like cafes, hotels, and airports can be risky because users often don’t know who controls the network or whether it is legitimate. A VPN encrypts the data traveling between the user’s device and the Surfshark server, which helps protect the content of communications from being intercepted on untrusted networks. However, a VPN cannot prevent users from entering credentials on fake banking sites, protect against reused passwords, or remove malware that’s already on a device. Surfshark also includes a feature called CleanWeb, which blocks ads, trackers, and domains linked to known threats. This can improve the browsing experience by reducing intrusive ads, pop-up windows, and suspicious websites. However, CleanWeb is not a full antivirus solution and cannot guarantee protection against all scams, as cyber threats evolve quickly. A VPN like Surfshark does not erase data that services already have, such as cookies, logged-in accounts, browser fingerprints, or data stored by online platforms. It also does not remove information that users have voluntarily published or profiles created by data brokers. Therefore, while a VPN reduces exposure on the network, it does not provide complete anonymity. Surfshark allows users to change their visible IP address and encrypt their internet traffic, offering flexibility in managing online connections. It supports an unlimited number of devices and includes advanced features like IP rotation, MultiHop, and Bypasser for more experienced users. The service is available on major platforms and offers a cost-effective plan, with a 2-year subscription including 3 extra months for 80.68 € TTC, or 67.23 € TTC with VAT reimbursement.
