How To Protect Your Data While Using Public Wi-Fi In 2025

Public Wi-Fi is a boon in smart cities, where you can stay connected to the internet wherever you go. You need not use expensive mobile data, as you would receive a free Wi-Fi connection. Places like airports, train stations, cafes, shopping malls, and all other commonly visited places have it. However, threat actors have converted this boon into a bane by creating a web of malicious activities around Public Wi-Fi.

This is why most security experts warn users to connect to private networks. However, if the situation arises and you must connect, you must verify that you are connected to the correct network and that your device is loaded with tools that will help protect your data. 

This guide is designed for people who have to use public Wi-Fi at some point to keep their devices and data protected from hackers.

What Is Public Wi-Fi

It refers to wireless internet networks that are available for use by the general people, typically in coffee shops, airports, libraries, hotels, shopping malls, restaurants, and other widespread areas. These networks are often provided free of charge or for a small fee and allow users to access the internet wirelessly on their mobiles or laptops. However, as said, this free service can cost hundreds or thousands of dollars yet people use it because –

• Either they don’t have a data connection or are out of cellular data.
• They want to access social media and save their data.
• Make calls using apps like WhatsApp, Facetime, etc.
• Be online while traveling.
• Stream content while minimizing the use of cellular data.
• Work remotely from a cafe
• Play games
• Make financial transaction
• Study

Here is a statistic provided by Forbes that shows the percentage of people using public wi-fi for different purposes.

What Are The Risks Of Using a Public Wi-Fi Network

These networks aren’t safe, but not all fall into the same category. Identifying which is safe and which isn’t is not easy. So you can say all free Wi-Fi’s are unsafe, and here are some common risks of using it:

• Hackers can use tools to intercept the data transmitted over public Wi-Fi and access sensitive information such as passwords, personal data, or financial details.
• Cybercriminals can position themselves between the user and the network, altering communications or stealing data.
• Some hackers set up fake Wi-Fi networks with names similar to legitimate public hotspots, tricking users into connecting. Once connected, the attacker can monitor or steal personal information.
• Cybercriminals can use unsecured networks to distribute malware. If they gain access to an open network, they might inject malicious software into your device.
• If you’re logged into a website or service (like email or banking) while connected to free Wi-Fi, a hacker could hijack your session and gain unauthorized access to your accounts by stealing your session cookies or credentials.

Is It Safe To Use A Public Wi-Fi Network That Isn’t Password-Protected

How To Browse Safely On Public Wi-Fi

We recommend against using free Wi-Fi, but if you have to, take care of the following factors before connecting and surfing the internet.

Point 1 – Use a VPN (Virtual Private Network)

A VPN encrypts all your internet traffic, even on an unsecured network, making it much harder for hackers to intercept your data. This is one of the best ways to secure your connection on public Wi-Fi when using a Windows laptop. 

I recommend using Systweak VPN. It is a powerful VPN that is compatible with Windows. I‘ve been using it for many years, even while traveling. It also helps me access the web in countries with restrictions. Here are the steps to use this VPN.

1. Download, install, and run Systweak VPN.

2. Create an account and log in.
3. Using Systweak VPN, connect to any server other than your country. Then open the browser and navigate to any website you want to.
4. Now, carry out the activity that you were planning to execute.

5. Disconnect when done, and that’s it.

Point 2 – Use HTTPS Websites

Ensure that the websites you visit use HTTPS (not just HTTP). The “S” stands for secure, meaning encrypted communication between your browser and the website. This protects your data from being intercepted.

Point 3 – Avoid Sensitive Transactions

Avoid accessing sensitive accounts (like online banking, email, or shopping) or entering personal information while connected to open Wi-Fi network, especially on unsecured networks.

Point 4 -Turn Off Sharing

Disable file and printer sharing and turn off any settings that allow your device to automatically connect to open networks. This will reduce your risk of unauthorized access to your device.

Point  5 – Use Two-Factor Authentication (2FA)

Enable 2FA for your online accounts whenever possible. Even if a hacker gains access to your login credentials, they would still need the second factor (like a code sent to your phone) to access your accounts.

Point 6 – Forget the Network After Use

Once you’re done using a public Wi-Fi network, make sure your device forgets it so it won’t automatically connect to it in the future.

Point 7 – Use Real-Time Antivirus Software

Real-time antivirus software monitors your system and prevents malware from entering your PC. It also warns you of suspicious activities and files on your PC that are not classified as malware. Many antivirus software programs are available in the global software market, but we recommend T9 Antivirus. This efficient antivirus helps users detect malware and manage Startup Programs.

Point 8 – Keep Your Device Updated

Whether you use a mobile phone, laptop, or tablet, it is necessary to regularly check for updates on your device and ensure they are completed successfully. All devices, irrespective of the OS (Windows, Android, macOS, iOS) receive regular updates from their manufacturers.

How To Protect Your Data While Using Public Wi-Fi Networks

1 – Use A VPN

VPN helps encrypt all outgoing and incoming traffic on your device using any internet connection. Hence, it is a must to enable a VPN before accessing Public Wi-Fi. On the other hand, it is advised to use a VPN when using a home network as well. This will ensure that your browsing data is encrypted and away from the eyes of your ISP, hackers, marketing agencies, and advertisers.

2 – Use Mobile Data Instead Of Public Wi-Fi

Many experts suggest using mobile phone data to access the internet when you are not close to your office or home Wi-Fi. This may seem to be a bit costlier, but nevertheless, it is very safe. You can also enable Hotspot on your mobile phone and provide a safe internet connection to your laptop or tablet.

3 – Use Strong Passwords

Strong passwords protect your accounts from unauthorized access, especially when using public Wi-Fi. Create complex passwords by combining uppercase and lowercase letters, numbers, and special characters to make them harder for hackers to guess. Security experts also recommend using unique passwords for each online service to minimize the risk of attackers gaining access to multiple accounts if one password is compromised.

[Conclusion]

To summarize, Public Wi-Fi is not safe and hence is not recommended. But when you have to book tickets online, carry out an important transaction, or reply to an email, you can connect to available free Wi-Fi in case your mobile data is not working. Before connecting, ensure your antivirus and VPN apps are enabled. After you complete your tasks, disconnect from the network and, most importantly, reboot your device. This will help keep your data safe and secure.
