We spend a lot of time on this site talking about the best cards, ATMs, and strategies for handling money abroad. But there's a piece of the puzzle that most travel finance guides ignore completely: what happens when someone intercepts your banking credentials on a hotel WiFi network in Barcelona, or steals your card details through an unsecured airport hotspot in Bangkok.
A VPN (Virtual Private Network) is one of the cheapest, easiest ways to protect yourself financially while traveling. It encrypts your internet connection so that no one on the same network can see what you're doing, whether you're checking your bank balance, logging into your brokerage account, or making an online purchase.
After testing several options, we recommend Surfshark for travelers. Here's why it matters and how it works.
The Problem: Public WiFi and Your Money
Every piece of travel advice tells you to use ATMs from major banks, carry no-fee cards, and always pay in local currency. That's all correct. But none of it helps if someone captures your login credentials before you even get to the ATM.
When you connect to WiFi at a hotel, airport, cafe, or Airbnb, your internet traffic passes through a network you don't control. On an unprotected connection, anyone on that same network with basic tools can potentially see:
- Which banking websites and apps you're accessing
- Login credentials if the connection isn't properly encrypted
- Credit card numbers entered on shopping sites
- Email contents, including password reset links and account notifications
- Session tokens that could let someone hijack your logged-in accounts
This isn't theoretical. WiFi-based attacks at hotels and airports are well-documented, and travelers are prime targets because they're constantly connecting to unfamiliar networks in unfamiliar places.
A Common Scenario
You land in Rome, connect to the airport WiFi, and check your bank account to make sure your travel notification went through. Then you open your email to confirm a hotel booking. Later that evening, you log into your credit card app at the hotel. Each of these actions on an unprotected network is a potential exposure point for your financial data.
How a VPN Protects You
A VPN creates an encrypted tunnel between your device and a secure server. All of your internet traffic flows through this tunnel, which means anyone monitoring the local WiFi network sees only encrypted gibberish instead of your actual data.
With a VPN running on your phone or laptop:
- Your banking sessions are encrypted. Even on a compromised hotel network, no one can see your bank login, account balances, or transaction details.
- Your card details stay private. Online purchases, app-based payments, and any financial data you enter are protected from interception.
- Your email is shielded. Password reset emails, account alerts, and booking confirmations containing sensitive details can't be read by network snoops.
- Fake WiFi networks can't trick you as easily. Even if you accidentally connect to a rogue hotspot set up to mimic your hotel's network, your data is still encrypted.
Think of it as the digital equivalent of using a bank ATM inside a secure branch instead of a sketchy standalone unit on a dark street. The transaction is the same, but the environment is far safer.
Why Surfshark Stands Out for Travelers
There are dozens of VPN providers, but most are designed for general privacy or streaming. Surfshark checks every box that matters specifically for international travel.
Unlimited Devices
Most VPN services limit you to 5 or 6 simultaneous connections. Surfshark allows unlimited devices on a single account. That means you, your partner, and your kids can all have VPN protection on phones, tablets, and laptops without paying extra. For a family trip, this alone makes it the better value.
3,200+ Servers in 100 Countries
Surfshark has servers in over 100 countries. This matters for travelers because you can always connect to a nearby server for fast speeds, or connect to a US server when you need to access your American bank or brokerage account from abroad.
Access Your Bank From Anywhere
Some US banks and financial institutions flag or block logins from foreign IP addresses. If you're in Thailand trying to check your Chase account or initiate a wire transfer through Schwab, you might get locked out or hit with extra verification steps. By connecting to a Surfshark US server, your bank sees a US-based connection and lets you in normally.
This is especially useful for:
- Checking bank balances and recent transactions
- Moving money between accounts
- Paying bills while you're away
- Accessing investment and brokerage accounts
- Using Venmo, Zelle, or other US-based payment apps
Camouflage Mode
Some countries restrict or monitor VPN usage (China, Russia, UAE, Turkey, and others). Surfshark's Camouflage Mode disguises your VPN traffic so it looks like regular internet browsing. This means you can still protect your banking sessions and access your accounts even in countries with internet restrictions.
Built-in Ad and Malware Blocking
Surfshark's CleanWeb feature blocks ads, trackers, and known malware domains. When you're traveling and clicking through unfamiliar local websites (restaurant menus, transit maps, attraction tickets), this adds another layer of protection against phishing sites designed to capture payment information.
Kill Switch
If your VPN connection drops unexpectedly, Surfshark's kill switch immediately cuts your internet access so that no unencrypted data leaks out. This prevents the brief moments of unprotected browsing that can happen when switching between WiFi networks at airports or moving between hotel floors.
What It Costs
Surfshark is one of the most affordable VPNs available, especially on the longer plans:
| Plan | Monthly Cost | What's Included |
|---|---|---|
| Starter (2-year) | ~$1.99/mo | VPN, ad blocker, cookie pop-up blocker |
| One (2-year) | ~$2.29/mo | Everything in Starter + identity protection, email aliases, data breach alerts |
| One+ (2-year) | ~$4.29/mo | Everything in One + Incogni data removal tool |
| Monthly | ~$15.45/mo | Same features, no long-term commitment |
The 2-year Starter plan works out to less than $50 total, which is less than what most travelers lose to a single DCC charge or foreign transaction fee incident. All plans include a 30-day money-back guarantee, so you can try it risk-free before your trip.
Real Travel Scenarios Where a VPN Saves You
Scenario 1: Hotel WiFi Banking
You're at a hotel in Lisbon and need to transfer money to cover a bill back home. Without a VPN, your banking session travels over the hotel's network in a way that could be monitored. With Surfshark connected, your entire session is encrypted. You connect to a US server, your bank sees a domestic login, and the transfer goes through without security flags.
Scenario 2: Airport Hotspot
During a layover at Istanbul Airport, you connect to the free WiFi to check your credit card statement and make sure your travel charges are posting correctly. Airport WiFi networks are some of the most targeted by attackers. With Surfshark running, your credit card app data is fully encrypted, even on the airport's open network.
Scenario 3: Cafe in Southeast Asia
You're working from a cafe in Chiang Mai and need to access your investment account. The cafe WiFi has no password. Without a VPN, this is one of the riskiest situations for financial data. With Surfshark, it doesn't matter. Your connection is encrypted end-to-end regardless of how insecure the local network is.
Scenario 4: Booking and Paying for Activities
You find a great day trip online and want to book it with your credit card. The booking site might not have the strongest security. With Surfshark's CleanWeb blocking known phishing domains and your connection encrypted, your card details are protected even on less reputable local websites.
How to Set Up Surfshark Before Your Trip
Getting set up takes about five minutes. Here's what to do before you leave:
- Sign up at surfshark.com. The 2-year Starter plan is the best value for most travelers. You can always upgrade later if you want the identity protection features.
- Install the app on all your devices. Surfshark has apps for iOS, Android, Windows, Mac, and Linux. Install it on every phone, tablet, and laptop you're bringing. Remember, unlimited devices means no limits.
- Test it at home first. Connect to a server in a different country and make sure you can still access your bank, email, and other financial apps. This confirms everything works before you're relying on it abroad.
- Turn on auto-connect. In Surfshark's settings, enable auto-connect so the VPN activates automatically whenever you join a new WiFi network. This way you're protected even if you forget to manually connect.
- Enable the kill switch. Go to settings and turn on the kill switch so your connection drops if the VPN disconnects unexpectedly.
Pro Tip: Download Before You Travel
Some countries restrict access to VPN websites and app stores. Download and install Surfshark before you leave home so you don't run into issues trying to set it up after arrival. If you're visiting China, Russia, or the UAE, this step is especially important.
VPN + Smart Card Strategy = Maximum Protection
A VPN works best as part of your overall travel money strategy. Here's how it fits together with the other tools we recommend:
- Use a no-fee travel card for purchases abroad so you're not paying 3% on every transaction.
- Use a travel debit card like Wise or Schwab for ATM withdrawals with fair exchange rates.
- Always refuse DCC at ATMs and payment terminals to avoid the 3-7% markup.
- Run Surfshark whenever you connect to WiFi abroad to encrypt your banking sessions and protect your card data.
- Bring some local currency from home so you're not scrambling to find a safe ATM the moment you land.
The cards handle the exchange rates and fees. The VPN handles the security. Together, they cover the two biggest ways travelers lose money abroad: bad rates and stolen credentials.
Frequently Asked Questions
Will a VPN slow down my internet?
Slightly, but Surfshark's speeds are fast enough that you won't notice it for banking, email, or browsing. Streaming video may buffer a bit more on very slow hotel connections, but for financial tasks, the speed difference is negligible.
Is it legal to use a VPN while traveling?
In the vast majority of countries, yes. VPNs are legal and widely used across Europe, the Americas, most of Asia, and Oceania. A few countries (China, Russia, UAE, North Korea, Iraq) restrict VPN use or block VPN traffic, which is why Surfshark's Camouflage Mode is valuable. Even in restrictive countries, using a VPN for personal security is generally tolerated.
Do I need a VPN if I only use my phone's cellular data?
Cellular connections are generally more secure than WiFi. If you're exclusively using cellular data (or a travel eSIM), the risk is lower. But the moment you connect to any WiFi network, you should have VPN protection. Most travelers use a mix of both, especially to avoid roaming charges.
Can my bank tell I'm using a VPN?
Some banks can detect VPN connections, but most US banks don't block them. If you connect to a US-based Surfshark server, your bank typically sees a normal US connection. In the rare case that a bank flags your login, you can verify your identity through their standard security questions, and then continue using the VPN normally.
What about using my phone's banking app?
Banking apps communicate over the same WiFi connection as everything else. A VPN protects app traffic just like browser traffic. Install Surfshark on your phone and leave it connected whenever you're on WiFi abroad.
Bottom Line
Your Travel Security Checklist
- Sign up for Surfshark and install it on all devices before your trip
- Enable auto-connect and the kill switch in settings
- Connect to a US server when accessing American bank and financial accounts
- Never access banking, email, or payment apps on public WiFi without VPN protection
- Test everything at home before you leave
You wouldn't leave your wallet open on a cafe table in a foreign city. Don't leave your financial data exposed on a foreign WiFi network either. A VPN is a small cost that protects the much larger investment you've made in travel cards, smart ATM strategies, and careful currency planning.
