Utah’s VPN liability law is a technical impossibility

Utah’s new age verification law, Senate Bill 73, attempts to legislate a technical reality that simply doesn't exist. By holding websites liable for users who mask their location with VPNs, the state has created a "compliance paradox" that forces platforms into an impossible corner. If you run a website, you are now expected to identify the physical location of a user who is actively using tools designed to hide that exact information.

Here is the reality that most lawmakers ignore: there is no reliable way for a website operator to detect a VPN at the application layer. While IP reputation databases like MaxMind can flag traffic from known commercial datacenter ranges, they are useless against residential VPN endpoints or personal WireGuard tunnels. If a user spins up a private instance on a cloud VPS, their traffic is indistinguishable from standard web hosting.

This next part matters more than it looks: the only way to truly identify VPN traffic is through deep packet inspection (DPI) at the network infrastructure level. Website operators do not have access to the ISP-level infrastructure required to perform this analysis. Unless you are an authoritarian regime with total control over your country’s internet backbone, you cannot force this level of surveillance.

The law creates a massive liability trap for businesses. To avoid potential legal action, many sites will likely resort to one of two extremes:

1. Blocking all known VPN IP ranges, which inevitably catches legitimate users like journalists, political dissidents, and privacy-conscious citizens.
2. Mandating aggressive age verification for every single visitor globally, effectively killing user anonymity and increasing the data breach surface area for the platform.

Why does this matter for your digital privacy strategy? Because this legislation treats the internet as a static, physical space rather than a global, routed network. By forcing websites to act as border guards, Utah is incentivizing the fragmentation of the web. If you are a developer or site owner, you are being asked to solve a problem that requires network-level visibility you don't possess.

This isn't just about age verification; it’s about the fundamental architecture of the internet. When states attempt to mandate the impossible, they don't stop the bad actors—they only punish the non-technical users who rely on privacy tools for safety. We are seeing a trend where online age verification laws are being used as a Trojan horse for broader internet surveillance.

If you are concerned about how these regulations impact your platform, start by auditing your current traffic filtering methods. You’ll quickly find that the "solutions" offered by vendors are just cat-and-mouse games against rotating IP addresses. The reality is that Utah’s VPN liability law is a technical impossibility that will likely result in more broken user experiences than actual compliance. Pass this to someone who thinks legislation can fix network-level anonymity.
