Netflix's US catalogue is widely considered the world's largest, with around 6,000+ titles spanning every genre — but step outside the United States and the library shrinks. The catalogue in the UK is missing roughly 40% of US titles. The library in Japan tilts heavily toward anime and Japanese originals. In Brazil and India, regional content dominates. These differences come down to licensing: studios sell streaming rights country by country, and Netflix's catalogue in each region reflects whatever deals it has signed there.
A VPN solves this by switching your apparent location. Connect to a US server and Netflix shows you the US catalogue. Connect to a UK server and you get British titles like Bridgerton extras and Top Boy. The Netflix app makes no distinction between a 'real' US user and a VPN-connected one as long as the connection looks like residential traffic — which is exactly what GhostShield's WireGuard tunnel produces.
