Using public wi-fi is like walking naked through a forest at night. You have no idea of the danger that stalks your every move before it finally pounces exploits your vulnerability.
Public wi-fi is mostly unprotected and holds no encryption. Connecting to it broadcasts your system to hackers who can use the unprotected tunnel as a way to gain access to it. Said hackers can then take a peek at what you’re doing and may even distribute malware without you noticing it.
This makes the problem a lot worse because public wi-fi is available at almost any coffee shop, airport, hotel, restaurant, and more.
If you want to remain safe and still use public wi-fi, then use a VPN. How does it protect you?
Anonymous Browsing–hackers won’t be able to find you if you’re under the cover of a VPN.
Encrypted–in the unlikely situation that hackers do find you, they won’t be able to access your situation that easily. A number of VPNs use military-grade encryption to protect you from these types of hacking.
When you’re looking for a VPN, consider the types of tunneling protocol and encryption that it uses. Lookout for protocols such as “OpenVPN”, “IPSec”, and “IKEv2”. These protocols provide Fort Knox-level of protection.
