The limitations of Public Wi-Fi

Put your hands up and tell me if you have ever walked into a local café and said: “ooooh, free WIFI.” You gave your full name and emailed away without a second thought to access free WIFI. Everyone has at least once; the following blog will recommend why you should not connect to Public WIFI. 

According to Norton, “A public wifi can be found in public places like airports, Coffee shops, malls, restaurants, and hotels, and it allows you to access the internet for free.” 

Business leaders will offer Customers free Wi-Fi to entice them to stay longer. But, unknowingly, they are also opening their customers to tremendous risks. 

Now, keep in mind that if you see the sign “WIFI is secure,” it does not necessarily mean so. This is because customers are only protected from outside this network; however not protected from customers using this network. 

The Risks to you 

The Man in the Middle 

This is the most common attack customers will fall victim too. The man in the middle, or simple hackers, are notorious for eavesdropping on Wi-Fi signals. When you connect to the public internet, a password is sent between your computer to the server, and vulnerabilities can allow attackers to read all your VALUABLE information. 

Fake Wi-Fi Spots 

Sometimes Cybercriminals take the time to create copycats or an evil twin of the original Public Network. For example, luring mobile users to willingly give up their information to these “Fake Wi-Fi Spots.” 

Unencrypted Network 

The chances are high for the following public network to be unencrypted. This means that the information sent between your computer and the server is accessible to be read to whomever. 


When an operating system is out of date, it is exposed to holes and weaknesses known as software vulnerabilities. Cybercriminals will exploit the following and will ensure malicious software known as Malware. Therefore, please ensure that you keep all devices up to date.
