The VPN Blind Spot: Why Regulators Struggle to Track Illegal Gambling

VPNs have become an easy headline in the debate over illegal online gambling. They are often presented as a loophole that lets players bypass geo-blocking, reach offshore casinos and avoid local restrictions. That view is partly true, but it also oversimplifies the issue. The bigger problem is not that every VPN user is moving to the black market. It is that VPN growth makes the black market harder to observe, measure and interpret.

This distinction matters. A rise in hidden traffic does not automatically mean a rise in illegal gambling. It may simply mean that the tools used to estimate online activity are becoming less reliable.

The UK is a useful case study. In its illegal gambling trends update, the Gambling Commission stressed that web traffic estimates are better for tracking direction than for producing market-size figures. That caution is important. Illegal gambling is not visible in the same way as licensed gambling, where operators report data, verify customers and work under regulatory supervision.

VPN use adds another layer of uncertainty. A VPN can mask an IP address, route traffic through another country and make a user appear to be somewhere else. For enforcement teams, this can weaken basic geo-blocking. For researchers, it can distort traffic estimates. For policymakers, it can make a volatile market look either larger or smaller than it really is.

The Online Safety Act has made the debate more urgent. Under the UK Online Safety Act framework, age-assurance duties pushed many platforms to introduce stronger checks. That changed user behaviour beyond gambling. Ofcom’s Online Nation 2025 report found that VPN usage more than doubled after highly effective age assurance became mandatory, peaking above 1.4 million daily users before later easing.

That does not prove those users were gambling illegally. Some may have wanted privacy. Others may have objected to age verification or tried to access restricted entertainment, social platforms or adult content. A smaller group may also have used VPNs to reach offshore betting or casino sites. The challenge is separating these behaviours.

This is why VPNs can become a red herring. They are relevant, but they are rarely the whole story. In many markets, users do not need a VPN to find unlicensed gambling sites. Offshore brands can be promoted through affiliates, search results, messaging apps, mirror domains and social media. Payment routes can also change faster than enforcement action.

For licensed operators, the practical question is not whether VPNs exist, but whether compliance systems are strong enough to detect suspicious activity. Modern gambling platforms can combine IP checks with GPS signals, device fingerprinting, payment data, account history and behavioural monitoring. Providers such as GeoComply’s geolocation technology describe VPN, proxy and Tor detection as part of broader location-fraud prevention. Still, technology only works when operators are required to use it and regulators can test it.

A better enforcement model should focus on the following priorities:

1. Measure illegal gambling through multiple indicators, including surveys, traffic trends, payment intelligence, affiliate monitoring and complaints.

2. Avoid assuming that reduced visibility equals market growth.

3. Strengthen action against unlicensed operators that actively target restricted markets.

4. Require licensed operators to apply layered location and identity controls.

5. Protect legitimate privacy tools rather than turning VPN use itself into a proxy for wrongdoing.

The Gambling Commission’s consumer engagement report shows how difficult this area is. The regulator describes its approach as data-led but caveated, because illegal gambling cannot be captured through a single clean dataset. That honesty is useful: it prevents exaggerated conclusions and creates room for better methodology.

The policy risk is overreaction. If governments frame VPNs as the main cause of illegal gambling, they may target privacy tools while leaving more important channels untouched. If they ignore VPNs completely, they may underestimate how much activity is hidden from conventional analysis.

VPNs are neither a harmless footnote nor the master key to illegal gambling. They are a signal that online enforcement is becoming more complex. The core problem is still the availability of unlicensed operators, weak disruption across borders and consumer demand for products that local rules restrict or licensed brands do not offer.

For gambling regulators, the lesson is clear: the future of enforcement cannot depend on IP addresses alone. It needs better evidence, cross-sector cooperation and a realistic view of what technology can prove.
