The COVID-19 pandemic transformed the way we work, with remote and hybrid models becoming the norm. As a result, many professionals now frequently rely on public WiFi hotspots at cafes, airports, hotels, and other public venues when working on the go.
Public WiFi networks are not as insecure as they were a few years ago, thanks to the widespread adoption of the HTTPS protocol by web browsers and applications, which encrypts data in transit.
However, public WiFi still poses security risks if not used cautiously. Practicing proper cyber hygiene remains of utmost importance when connecting to public networks.
Here are five crucial tips to protect your sensitive data and online privacy when using public WiFi in 2024.
How to Use Public Wi-Fi Safely
1. Verify the Network’s Legitimacy
Scammers often set up rogue WiFi hotspots with enticing names like “Free Airport WiFi” to lure unsuspecting users. Always confirm the official network name by checking for posted signs or asking venue staff.
Most modern WiFi networks can detect and block rogue access points, but it’s still wise to double-check.
Why is this important? Rogue WiFi hotspots allow cybercriminals to intercept and view all internet traffic passing through them, including login credentials, banking information, and other sensitive data.
They can even redirect you to malicious websites designed to install malware or steal personal information.
2. Limit Sensitive Information Sharing
Avoid entering sensitive data like login credentials, banking details, or personal information on public WiFi whenever possible. If required to register with an email or set a password, use a secondary address and a unique, disposable password.
Even if the public WiFi network is legitimate, it may still be vulnerable to cybercriminals using packet sniffing tools to capture unencrypted data transmitted over the network. Any sensitive information you enter, from passwords to credit card numbers, could potentially be intercepted and stolen.

It’s best to postpone accessing financial accounts, confidential work materials, or other sensitive online activities until you’re securely connected to a private network you control and trust, such as your home or corporate WiFi.
3. Forget Networks After Use
Your devices may automatically reconnect to previously used public WiFi networks, which could have been compromised since your last visit. Configure your devices to forget networks or disable automatic reconnection for added security.
Automatic reconnection can be convenient, but it also poses risks if the network name has been spoofed or compromised by bad actors since you last connected.
Forgetting public WiFi networks forces you to manually reconnect each time, reducing the chances of accidentally joining an insecure rogue hotspot.
Most modern operating systems and devices have settings to prevent automatically reconnecting to WiFi networks or to forget networks after a set period of inactivity. A few moments of caution can prevent a major privacy breach or cyberattack.
4. Use a Reputable VPN
A virtual private network (VPN) encrypts your internet traffic and hides your IP address, protecting your online activities from snooping on public WiFi. Paid VPN services from reputable providers are generally more secure than free offerings.
Using a VPN creates an encrypted tunnel for data transmission, shielding your internet connection from packet sniffing or eavesdropping, even on unsecured public WiFi networks. The VPN server also functions as a proxy, masking your device’s actual IP address and geographic location.

While some free VPN services exist, they often lack robust security protocols, have bandwidth limitations, and may even compromise your privacy by tracking your online activities for advertising purposes.
Reputable paid VPN providers with transparent privacy policies, strong encryption standards, and global server networks are worth the modest subscription cost for frequent remote workers and travelers.
5. Use Your Smartphone’s Hotspot
As an alternative to public WiFi, consider using your smartphone’s mobile hotspot feature to connect your laptop or other devices. With widespread 5G adoption, hotspot connections can be faster and more secure than overcrowded public networks—just be sure to enable hotspot security with a strong password.
By tethering other devices to your smartphone’s mobile data connection, you bypass the risks associated with public WiFi entirely. Most modern smartphones support secure WiFi hotspot functionality, with data speeds frequently rivaling or surpassing those of public hotspots as 5G coverage rapidly expands.
However, to prevent unauthorized access, be sure to enable your smartphone’s hotspot security settings and set a strong, unique password that can’t be easily guessed. An open, unsecured mobile hotspot could allow nearby threat actors to access your personal data or launch attacks, just like an unsecured public WiFi network.
Remote and Mobile Work Requires Proactive Cyber Hygiene
With the shift towards remote and hybrid working models, more professionals are relying on public WiFi out of convenience or necessity when traveling or working outside the office. However, the inherent risks of open public networks necessitate adopting stringent cyber hygiene habits to protect sensitive data and online privacy.
By verifying network legitimacy, limiting sensitive data transmission, forgetting networks after use, utilizing a trusted VPN service, or simply tethering to your smartphone, you can significantly reduce the attack surface for cyber threats when working remotely.
A few simple precautions can prevent devastating data breaches, identity theft, and other cyber attacks facilitated by unsecured public WiFi.
As the modern workforce becomes increasingly mobile and distributed, proactive cyber hygiene practices regarding public WiFi usage should become second nature.
Adopting a security-first mindset can safeguard your personal and professional data from malicious actors seeking to capitalize on the convenience of public internet access. Stay vigilant and implement these essential tips to ensure safe, worry-free productivity from anywhere in 2024 and beyond.
