In the United States, legal online casinos, betting sites, and gambling apps are already part of many people’s digital routine. The online gambling sector handled around $12.68 billion in 2024 and is expected to reach nearly $13.9 billion in 2025, with projections of close to 10 percent annual growth through the end of the decade.

In parallel, the regulated iGaming segment in just a handful of states has already passed $8.4 billion in annual revenue, with growth of almost 30 percent in a single year. So it is no surprise that bonus notifications, free spin offers, and welcome packages with extra cash are popping up on screens all the time.

More and more, that tap to activate happens away from home – on hotel networks, airport Wi-Fi, coffee shop connections, college campuses, or even inside a mall. For many casual players, opening a casino app on hotel Wi-Fi feels as automatic as checking email.

A flashy banner promising free spins or a generous boost on the first deposit is often enough to make someone tap claim without thinking too much about who else is on that same network. Online casino promotions are designed to be frictionless – one tap to join, another to deposit. That fluidity is great for the experience, but it becomes a real problem the moment it means sending logins, card details, and KYC documents over an open connection. This is exactly where a VPN comes in: it doesn’t change the bonus terms or turn a weak offer into a good one, but it encrypts the traffic around signup, identity verification, and payment, so the hunt for extra value doesn’t turn into an invitation for cybercriminals.

Why Bonus Hunting on Public Networks Is Riskier Than It Feels

Competition between operators in the US is intense. Reports from the American Gaming Association show that in 2024, the combination of online sports betting and iGaming already accounted for almost one-third of total commercial gaming revenue, with about $6 billion generated in the third quarter of 2025 alone.

As more money flows through the system, the offers used to attract and retain players become more aggressive: deposit matches, free spin packages, limited-time cashback, slot tournaments, and missions with extra rewards. In states with regulated iGaming, virtually every major operator offers some kind of welcome bonus or recurring promotion, and the average player now expects that as part of the onboarding experience.

The catch is that hotel, airport, or coffee shop Wi-Fi looks like a simple convenience but hides a lot of activity in the background. Open networks, or ones protected only by a simple password shared with hundreds of strangers, are constant targets for man-in-the-middle attacks and fake “evil twin” hotspots that mimic the name of the real network to capture traffic.

When a player taps to activate a promotion in that kind of environment, they typically log into their casino account (exposing username and password if the connection is compromised), then enter payment details such as a credit card, bank account, or digital wallet. In many regulated casinos, there’s also an identity verification step requiring a photo ID, a selfie, and proof of address – each one generating sensitive traffic that travels over the same shared network, often with no protection beyond HTTPS.

On the other side of that connection, cybercriminals are working in a risk landscape that keeps growing. An FBI report shows the Internet Crime Complaint Center (IC3) received about 859,000 cybercrime complaints in 2024, with reported losses exceeding $16 billion, a 33 percent increase over the previous year, driven largely by phishing, personal-data theft, and account hijacking.

Quick Checklist Before You Tap “Claim”

Rather than another generic rundown of what a VPN does, here’s the sequence worth actually following the next time a bonus notification pops up while you’re away from home:

1. Connect to the VPN first, open the casino app second. Activating protection after you’ve already logged in defeats the purpose.
2. Confirm the kill switch is on. If the VPN connection drops mid-session, a kill switch stops your device from silently falling back to the open network.
3. Check for DNS leak protection in the app settings. This keeps your browsing requests from bypassing the encrypted tunnel even when the rest of your traffic is protected.
4. Avoid uploading KYC documents on a network you don’t control, even with a VPN running, if the network itself looks unusually slow or the Wi-Fi name looks slightly off from what the venue actually advertises.
5. Log out and disconnect the VPN only after the transaction confirms, not the moment the page appears to load.

What a VPN Actually Does at the Moment You Activate a Promotion

This is where a modern VPN plays a central role. It creates an encrypted tunnel between your device and the VPN server, scrambling your traffic so that even if someone is snooping on the same public network, all they see is unreadable data. That protection covers not just your browser but apps running in the background too, including banking apps, digital wallets, and gambling platforms – meaning your casino login, card entry, and document uploads travel through an encrypted channel even on hotel or airport Wi-Fi.

Your real IP address is also masked, which makes tracking harder for bad actors and reduces the chance of exposing your location or home network. None of this changes the odds on a slot machine or the terms of a welcome bonus — it simply means that claiming one on the road doesn’t have to come with a side of identity risk.
