FAQ · Public Wifi Safety

Public wifi is not inherently safe, because it is a shared network on which anyone else connected can potentially monitor or intercept your traffic; Fresh Mango Technologies recommends using a phone's mobile data connection instead whenever it is available, since it is encrypted and private in a way open public wifi is not.

What makes public wifi risky

When you join a public wifi network at a cafe, airport or hotel, you are sharing that network with every other device connected to it, some of which may be run by someone actively looking to intercept traffic. Unencrypted public networks make it straightforward for another user on the same network to see the data passing between your device and the sites you visit.

Safer alternatives and precautions

Use your phone's 4G or 5G mobile data connection where possible — it is encrypted and private to you, unlike shared public wifi.
If public wifi must be used, avoid logging into banking, email or business systems while connected.
Use a VPN to encrypt your traffic if you regularly need to work over public networks.
Confirm you are joining the venue's legitimate network name — attackers sometimes set up look-alike wifi hotspots with a similar name to the genuine one.

Frequently asked questions

Is a hotel's paid wifi any safer than free public wifi?

Not necessarily — paying for access does not change whether the network is encrypted or how many other guests are sharing it. Treat paid hotel wifi with the same caution as any other public network.

Does using a VPN make public wifi completely safe?

It substantially reduces the risk by encrypting your traffic before it leaves your device, but it does not eliminate every risk, such as a compromised device on the network attempting other attacks.

Is using my phone as a mobile hotspot for a laptop safer than public wifi?

Yes, because you control the network and it uses your mobile data connection rather than a shared public one.
