Why use a VPN with OPNsense?
OPNsense is a powerful open-source firewall and routing platform that can act as the hub for your entire network’s privacy and access controls. Adding a VPN helps you:
- Encrypt traffic leaving your network, even on public Wi‑Fi
- Access resources remotely without exposing them to the internet
- Bypass geo-restrictions for legitimate business use where permitted
- Improve privacy by masking external destinations from your ISP
Key numbers to know
