🔐 Proxy VS VPN 🔐
Proxy🔓👨🏻💻 -
🚪 Acts as a gateway, functioning like anonymous web browsing.
🔓 Private data is vulnerable.
⚠️ Low level of security.
💰 Low cost.
📄 Limited to certain browsers only.
🛠️ Modifies your traffic before it reaches the target.
VPN 🔐👨🏻💻 -
🔐 Establishes a secure tunnel between your device and the VPN server.
🥷 User data is fully encrypted.
✅ High level of security.
💸 Higher cost.
💻 Compatible with all operating systems (OS).
🛡️ Encapsulates traffic before sending it to the target.
