Is Hotel WiFi Safe? A Traveler’s Guide to Staying Secure on Hotel and Airport Networks

You check into a hotel after a long flight, open your laptop, and connect to the hotel Wi-Fi to catch up on email before dinner. It feels routine. It’s anything but.

Hotel and airport Wi-Fi networks are some of the most targeted public networks in the world. In a 2019 study by WatchGuard Technologies, security researchers tested Wi-Fi security across 45 locations in five countries and not a single hotel passed the test. According to industry research, hotels are the third most common target of cyber attacks, accounting for 13% of all cyber compromises. If you travel for work and connect to hotel or airport networks without a plan, your business data is one man-in-the-middle attack away from ending up somewhere it shouldn’t be.

This guide covers what makes hotel Wi-Fi dangerous, how to use it safely when you have to, and when you should skip it entirely.

For the fundamentals of how public Wi-Fi attacks work, see our public Wi-Fi security guide.

Is Hotel Wi-Fi Safe?

Short answer: no, not by default. Hotel Wi-Fi is often unsecured, frequently protected with weak passwords (or no real protection at all), and shared by hundreds of guests on the same network. That combination makes it an easy target for attackers looking to intercept data, inject malware, or set up fake networks.

The risks are not theoretical. If you connect without protection and use that connection for anything sensitive, you’re taking a real risk.

That said, hotel Wi-Fi can be used safely with the right precautions. The rest of this guide walks through them.

Why Hotel and Airport Networks are Especially Risky

Hotel networks have a specific risk profile that makes them more dangerous than the coffee shop down the street:

• Long connection times. A business traveler might be on the same hotel Wi-Fi for three or four days. That’s a much longer window for an attacker to intercept data or pivot to your device than the 20 minutes someone spends at Starbucks.
• Mixed guest populations. Anyone staying at the hotel is on the same network. That includes whoever is two rooms down running packet-sniffing software from their laptop.
• Weak backend security. Many hotels use weak Wi-Fi passwords and run outdated networking equipment. Security patches for hotel Wi-Fi systems often go uninstalled for months.
• High-value targets. Hotels attract business travelers with company credentials, corporate email access, and sometimes sensitive work materials. That makes hotel networks attractive to cybercriminals in a way that residential Wi-Fi isn’t.
• Captive portals. The login page you see when you first connect to hotel Wi-Fi (the captive portal) can be spoofed. A fake portal can harvest your name, room number, and email before you ever make it to the real internet.

Is Airport Wi-Fi Safe?

Airport Wi-Fi has its own set of issues. Free airport Wi-Fi is some of the most heavily targeted public Wi-Fi in the world because of who’s using it: travelers with laptops open, logged into work email, trying to kill time before a flight.

The biggest airport-specific risk is evil twin attacks. Cybercriminals set up fake networks, sometimes called “honeypots,” with names that mimic legitimate airport Wi-Fi. You see “Free_Airport_WiFi,” “Airport_Guest,” or something that looks close enough to the official network name, and you connect. Every bit of data going through that connection now passes through the attacker’s device first.

The FBI has specifically warned travelers about the risks of using hotel and airport Wi-Fi networks for remote work. Treat airport Wi-Fi with the same suspicion as hotel Wi-Fi. If you absolutely need to use it, verify the network name with airport staff or signage (not the list of available networks on your device), keep your VPN active, and don’t do anything sensitive.

Can Hotel Wi-Fi be Hacked?

Yes, and it’s easier than most guests realize. The most common attacks against hotel Wi-Fi include:

• Man-in-the-middle (MITM) attacks. An attacker positions their device between yours and the hotel access point, intercepting your traffic. You don’t get a warning. The connection feels normal. Everything you send, login credentials, emails, files, all of it passes through the attacker first.
• Packet sniffing. On unsecured networks, anyone connected can use freely available software to capture unencrypted data. Passwords, credit card numbers, and other sensitive information transmitted over HTTP (not HTTPS) can be read directly.
• Session hijacking. Attackers steal session cookies from your browser, then impersonate you on websites you’re logged into: your email, your work dashboard, your bank.
• Malware injection. On unsecured networks, attackers can exploit vulnerabilities in your device to install malicious software without your knowledge.
• Fake networks and honeypots. Attackers set up a rogue hotspot with a name nearly identical to the official hotel network. Guests connect to the fake network, and every piece of their internet traffic is monitored.

Do Hotels Monitor your Wi-Fi Activity?

Hotels generally can see which websites you connect to (at the domain level) through their network logs. They typically don’t see the contents of your traffic if you’re using HTTPS, which most modern websites do. But their ability to log metadata is real, and some hotels retain that data for extended periods.

If you want full privacy from the hotel itself, a VPN prevents the hotel network from seeing anything beyond “this guest is connected to a VPN server.”

Is Hotel Wi-Fi Safe with a VPN?

A VPN dramatically improves the safety of hotel Wi-Fi. A VPN encrypts your internet traffic, making it unreadable to anyone monitoring the hotel network, including the hotel itself, other guests, and any attacker running a MITM attack. Even if someone intercepts your connection, all they see is encrypted data.

Hospitality industry surveys indicate that 80% of hotel guests use Wi-Fi for remote work, making a VPN essential for protecting against data breaches during business activity. If you’re traveling for work, a VPN is not optional.

A few VPN-specific tips for hotel use:

• Turn the VPN on before you open the captive portal. Some hotels require you to disable the VPN briefly to authenticate, then you reconnect. Reconnect the VPN immediately after authenticating and before doing anything else.
• Use a VPN with a kill switch feature. A kill switch automatically disconnects your device from the internet if the VPN drops, so you’re never accidentally transmitting unencrypted data.
• Avoid free VPNs. Free VPN services often monetize your data, inject ads, or use weak encryption. If the VPN itself is compromised, it’s worse than no VPN at all.

A VPN is your most important protection on hotel Wi-Fi, but it’s not the only one. The rest of the best practices below matter too.

How to Safely Use Hotel Wi-Fi for Business

If you have to do work from a hotel, follow these steps:

1. Confirm the correct network name. Ask the front desk for the exact hotel Wi-Fi name. Cybercriminals set up fake networks with names that look nearly identical to the official one. One extra character is all it takes.

2. Enable your VPN before connecting. Your VPN encrypts your traffic end-to-end. Turn it on first, then connect. If a captive portal blocks the VPN, disable briefly, authenticate, and re-enable before doing anything else.

3. Disable auto-connect on your devices. Disabling auto-connect prevents your device from automatically joining a malicious network that happens to share a name with one you’ve used before. On Windows, manage this in the Wi-Fi settings panel. On macOS and iOS, turn off “Auto-Join” for known networks you’ve used while traveling.

4. Turn off file sharing. Before connecting, disable file and printer sharing. On Windows, this is under Control Panel > Network and Sharing Center > Change advanced sharing settings. On macOS, check System Settings > General > Sharing.

5. Keep your firewall enabled. Windows Firewall (or the macOS equivalent) blocks unauthorized connections to your device. Leave it on, always.

6. Use reputable antivirus software. Keep antivirus programs current with the latest definitions. Good antivirus software catches malware threats before they execute, including those that hotel networks sometimes try to push through injected code.

7. Only visit HTTPS websites. Look for the padlock in the address bar. HTTPS encrypts the connection between your browser and the site. If a site isn’t HTTPS, don’t enter anything you wouldn’t put on a postcard.

8. Enable multi-factor authentication on sensitive accounts. If your password does get intercepted, MFA means the attacker still can’t get into your email, bank, or work systems without your second factor. Turn it on for every account that matters: email, banking, social media, cloud storage.

9. Avoid sensitive transactions. Even with a VPN, skip online banking, tax filing, or access to confidential work materials on hotel Wi-Fi if you can. If it can wait until you’re on a trusted connection, let it wait.

10. Keep your operating system and software updated. Scammers exploit vulnerabilities in outdated software to hack devices connected to hotel Wi-Fi. Operating system updates and security patches close those doors before attackers can walk through them.

11. Watch for pop-ups. Hotel captive portals shouldn’t ask you to install software, update Flash, or download a “security certificate.” Any pop-up asking you to install something is a red flag, close it and verify with hotel staff.

Should you use Hotel Wi-Fi or a Mobile Hotspot?

If you have adequate mobile data, your phone’s hotspot is almost always the better choice for business work while traveling. A mobile hotspot gives you:

• A connection encrypted by your cellular carrier
• A password you control
• Visibility into who’s connected (only your devices)
• No shared access with hundreds of other guests

For checking email, accessing a CRM, joining a video call, or handling any work that touches sensitive data, use the hotspot. Save hotel Wi-Fi for streaming, casual browsing, or anything where the worst-case scenario is boredom rather than a breach.

Before you Connect: the Traveler’s Checklist

Run through this every time you connect to hotel, airport, or any public travel network:

• Have you confirmed the correct network name with staff or signage?
• Is your VPN active with a kill switch enabled?
• Is auto-connect disabled on your device?
• Are file sharing and printer sharing turned off?
• Is your firewall enabled?
• Is your antivirus software up to date?
• Is your operating system fully patched?
• Are you avoiding sensitive accounts unless absolutely necessary?
• Does every site you visit show HTTPS and a padlock?

If any of these is a no, fix it before you connect, or use your mobile hotspot instead.

How to Safely use Airbnb Wi-Fi

Airbnb and short-term rental Wi-Fi is often worse than hotel Wi-Fi. The host’s router may not have been updated in years, the Wi-Fi password is typically shared with every guest who’s ever stayed there, and the host (or a previous guest) could have installed monitoring software on the router.

Treat Airbnb Wi-Fi the same way you’d treat an unknown coffee shop network: use a VPN, avoid sensitive activity, and lean on your mobile hotspot for anything work-related. If you’re staying somewhere for more than a few nights and need reliable work connectivity, a travel router paired with your own mobile hotspot or eSIM data plan is worth the small investment.

International Travel: Is Public Wi-Fi Safe Abroad?

International public Wi-Fi carries all the same risks as domestic Wi-Fi, plus a few more:

• Different legal standards for data privacy. Your data may be legally monitored or retained in ways it wouldn’t be at home.
• State-sponsored surveillance in some countries. Business travelers to certain regions should assume all network traffic is monitored.
• Language barriers around scams. Spotting a phishing attempt or fake network is harder when the prompts are in a language you don’t speak fluently.

A VPN is non-negotiable for international business travel. Some countries restrict VPN use. Research local laws before you travel and, if needed, install and test your VPN before you leave home. If your company handles sensitive data, check with your IT team (or your managed IT services provider) about region-specific policies before connecting to any public network abroad.

Protect your Business at Every Connection Point

Hotel Wi-Fi, airport Wi-Fi, Airbnb Wi-Fi, and every other public network your employees touch while traveling represent real risk to your business. A single compromised laptop can expose customer data, financial information, or credentials that attackers use to pivot into your broader network.
