How Freelancers Can Protect Client Data on Public Wi-Fi
A freelance bookkeeper opens her laptop at a café that advertises free Wi-Fi. She connects to “CafeGuest_Free” to send a client’s invoices, unaware that the real network is “CafeGuest.” The fake network belongs to an attacker who intercepts her data as soon as she connects and changes the bank details on her invoices.
If you work remotely from hotels, cafés, or coworking spaces, you could face the same attack. To avoid falling victim, start with a VPN, which encrypts your connection so anyone snooping on the network sees only gibberish. Antivirus software adds a second layer by blocking malware downloads triggered by fake update pop-ups, another way cybercriminals steal data. An antivirus with VPN covers both jobs.
Why Remote Work Puts Client Data on Shared Networks
You already know the pattern: some days at home, some in airport terminals and cafés, checking client files and entering payment details on whatever network is available.
Office employees benefit from IT security measures on their network. As a freelancer, you are the only security the client has against other network users accessing their confidential information. Spotting a spoofed network is on you.
Gallup’s data shows how widespread remote work is. As of May 2026, 52% of remote-capable employees in the U.S. work hybrid, and 26% work fully remote. The more people working outside an office, the more client data crosses networks that no one is securing.
How Attackers Target Hotels, Cafés, and Coworking Spaces
Attackers adapt their approach to each location. They study the network, the crowd, and the habits of the people there to find a way in.
Hotels
Many hotels send you to a login page that asks for your room number or last name. An attacker can copy that page and add a fake prompt claiming you must update before you can get online. With a client call minutes away, you click, and malware can install on your laptop, exposing client files and payment details.
Cafés
Most websites now encrypt traffic, so café Wi-Fi is safer than it used to be. But a fake hotspot - an evil twin - doesn’t need to break that encryption. It shows you a convincing login page and collects whatever you type. That password might open a client’s code repository or billing dashboard.
Coworking Spaces
An attacker watching unprotected traffic in a coworking space can capture your email session. From there, they can impersonate you to your clients and redirect payments - business email compromise, which the FBI’s 2025 Internet Crime Report ties to more than $3 billion in reported losses.
How to Protect Client Data on the Road
These habits close most of the gaps attackers seek to exploit.
Turn off auto-join, so your device doesn’t connect to a lookalike network on its own.
Confirm the network name with staff before you connect.
Use a VPN on shared networks.
Enable multi-factor authentication, so a stolen password alone can’t open your accounts.
Use a personal hotspot for sensitive work, such as client payments.
Install updates from your device’s settings, never from a pop-up.
Run antivirus software so it can block malware before it spreads.
No single habit covers every risk, so layer them.
Before Your Next Café Session
The bookkeeper’s mistake took one tap on the wrong network name. Before you send an invoice or open client files, delete saved networks you don’t recognize, switch on multi-factor authentication for all your business email accounts, and confirm the network name with staff. These steps are small, but together they help protect you and your clients’ trust.
