What is the risk of using public Wi-Fi networks without a VPN?

Using public Wi-Fi networks without a VPN significantly increases the risk of data interception and hacking attacks. Public networks are often unsecured or have minimal security measures, making them prime targets for cybercriminals. When connected to such a network, your device can be more easily accessed by unauthorized users who might attempt to steal sensitive information, such as passwords, credit card numbers, or personal data.

A VPN, or Virtual Private Network, encrypts your internet traffic and disguises your IP address, helping to secure your online activities from prying eyes. This added layer of protection mitigates the risks posed by using public Wi-Fi, as it makes it much harder for attackers to intercept your data.

The other choices do not accurately reflect the potential risks associated with unprotected public Wi-Fi. Increased data speed is not a characteristic of unsecured networks and can often be slower due to congestion. A loss of internet connection could happen on any network and is not specific to public Wi-Fi or the use of a VPN. Reduced battery life could be a concern while using any Wi-Fi, but it is not directly related to security risks.
