15. WireGuard

WireGuard is a common concept in the VPN world. A premium vpn provider typically treats this area as a core feature, because it affects privacy, security, and day‑to‑day reliability for streaming, gaming, trading, and AI/LLM use. In simple terms, it influences how your device authenticates, encrypts traffic, routes packets, and avoids leaks. When evaluating options, look for clear explanations, sensible defaults, and controls that match your threat model and speed needs. WireGuard is a modern protocol designed for speed and strong security with a small, easier‑to‑audit codebase.
