Yes. In some countries, ISPs aggressively monitor internet traffic and may block, throttle, or flag IPTV usage. Using IPTV without a VPN exposes your real IP address, browsing patterns, and subscription details to your ISP. In regions with strict copyright rules, this may trigger automatic warnings or service restrictions. A VPN encrypts your traffic, hides your IP, bypasses ISP throttling, and protects your identity. Premium providers recommended by Glanfy perform best with VPNs because they support stable encrypted HLS/HTTPS streams.
