| L2TP/IPSec | IPSec | Up to 256-bit |
| PPTP | MPPE | Up to 128-bit |
The strength of the encryption used will depend on the protocol being used and the capabilities of the VPN gateway. Generally, the stronger the encryption, the more secure the connection will be.
Tunneling Protocols
There are also several tunneling protocols used in VPN gateways, including:
- Point-to-Point Tunneling Protocol (PPTP)
- Layer 2 Tunneling Protocol (L2TP)
- Internet Protocol Security (IPSec)
- Secure Sockets Layer (SSL) and Transport Layer Security (TLS)
- OpenVPN
Each protocol has its own advantages and disadvantages, and may be more suitable for certain use cases or devices.
Overall, the combination of encryption and tunneling used in VPN gateways ensures that data is protected from interception and unauthorized access, providing users with a secure and private connection to the internet.
