Proton VPN is a macOS virtual private network app from ProtonVPN AG that encrypts internet traffic and helps protect privacy on public or restricted networks.
What is Proton VPN?
Proton VPN is a Mac VPN application published by ProtonVPN AG for creating encrypted connections between your device and Proton's VPN servers. It is typically used to protect traffic on public Wi‑Fi, reduce exposure to local network monitoring, and access region-dependent or restricted online services through remote VPN endpoints. On macOS, the app integrates with the system's VPN and network extension framework, and Proton documents features such as Kill Switch, Smart Protocol, WireGuard-based connections, DNS leak protection, custom DNS, and optional auto-connect behavior. Users usually encounter it as an installed app in /Applications with menu bar presence and optional start-on-boot behavior. Proton also documents account sign-in, server selection, connection profiles, and settings for protocol choice, LAN access, and privacy-related connection behavior. It is a legitimate consumer security tool when obtained from Proton's official site.

Safety overview
Status: Safe
This is a legitimate VPN client from ProtonVPN AG. It handles network traffic, account sign-in, and VPN configuration on the Mac, so it has elevated privacy relevance, but it is not generally considered malicious when downloaded from Proton's official website.
Recommendation: Keep it if you actively use Proton VPN or need its background VPN integration and startup behavior. If you no longer use Proton's service, removing the app is usually reasonable after disconnecting the VPN and uninstalling it normally.
