One reason has to do with the encryption protocol used by some wireless networks. Another has to do with the possibility of joining a fake or rogue Wi-Fi hotspot. Some wireless networks may use older standards for encryption which can raise your security risks. Wireless encryption protocol WEP , one of the first encryption conventions for wireless networking devices, is considered weak and easily susceptible to being hacked.
Wi-Fi protected access WPA was intended to replace WEP as the standard for wireless networking devices, but it too was found to have weaknesses. Users are especially at risk when connected to a wireless network that uses those outdated encryption protocols.
Another issue? When attempting to use free public Wi-Fi, you may be at risk of joining a rogue Wi-Fi hotspot. In such cases, an attacker creates a fake hotspot with the intent to perform man-in-the-middle MITM attacks on unsuspecting victims that join their rogue network.
If successful, this type of attack allows cyberthieves to intercept the communication between you and the servers of the websites you visit, allowing them to read, insert, and modify messages and data.
With pre-built kits that can perform MITM attacks, even minimally skilled hackers can eavesdrop and monitor your online traffic to capture valuable information, such as login credentials, credit card numbers, and Social Security numbers. A lot of people likely will try to connect, especially if free Internet service is being offered. You might be away from home — at a coffee shop, for instance — and suddenly your computer shows that you're connected to your home network.
Never use public Wi-Fi networks to access sensitive information. Be sure to choose one from a reputable security provider. Once connected to the VPN, it creates a private network, or tunnel, through which you send information back and forth, adding an extra layer of security to your connection. Website addresses that start with https are encrypted, adding an extra layer of security and making your browsing more secure.
If you connect to an unsecured Wi-Fi network and use regular http instead of https, your traffic could be visible to anyone else on the network. Click the shield icon to the left of the address bar. Cookies are now enabled for all webpages that are part of the avast.

The next step is to fortify your browser with tools designed to protect your privacy. The best protection from an untrusted network when you have to use one, I think, is direct, encrypted access to a trusted one. That goes double for mobile VPNs , which can be riddled with malware and soak up private information while you use them.
