L2TP/IPSec VPN Protocol
L2TP/IPSec is a VPN (Virtual Private Network) protocol, same as PPTP, which is responsible for setting up a private and secure Internet connection. It is the replacement that is recommended for PPTP, where data encryption of a secure nature is required. When you use the L2TP/IPSec VPN protocol, the “tunnel” (Internet connection) is encrypted with the IPSec protocol.
The tunnel is therefore provided by the L2TP and the encryptions come from the IPSec. As soon as a secure connection is created, IPSec encapsulates the L2TP packets between the VPN and your device. Because the L2TP packets are hidden inside the IPSec packets, nobody is able to read information from the internal private network.
This is one of the best options offered for mobile devices. IPSec has no real problems or vulnerabilities and it is considered very secure, which is one reason for its popularity. All the current mobile platforms such as Android and iOS (iPad, iPhone) have the necessary support for L2TP/IPSec already built in. Additionally, all Mac OSX later than 10.3+ and Windows versions after 2000/XP has the same support built in for L2TP/IPSec.
Worldwide ISP’s and governments are controlling and limiting what customers and residents can access online. Emails are scanned, your connection speed is throttled, social networks are monitored and often blocked and some citizens are unable to view content and messages from certain countries. Thanks to a VPN, customers now have the answers to this ongoing invasion of privacy in three ways:
Whenever you connect to Wi-Fi at a hotel or even at the airport, or when you send an email using your mobile device, you sacrifice your own security. By allowing your Internet connection to be encrypted, you can secure all the data you send and receive.
Privacy and anonymity
Privacy and anonymity are not the same and should not be confused. A VPN will prevent any strangers from “looking into your house”. It will ensure your privacy and you have control over who may, and who may not “look in”, this is assured by encrypting. Beside that you can hide IP address because for the rest of the world you gain IP of the VPN server you are connected to, and this assures your anonymity.
The ISP DPI, or deep packet inspection threatens to wipe away any expectation of freedom and privacy for many Internet users. A proper VPN will shield you from this DPI and will ensure that your right to privacy is in your own hands.
When and why should you use L2TP/IPSec?
- It has much better compatibility with corporate firewalls and all wireless routers.
- Very simple to set-up. No software from third parties is needed and most operating systems support it. Even mobile devices support it already.
- Offers 256-bit encryption, which is the same strength that most financial institutions use as well.
- It ensures not only the confidentiality of your data, but data integrity too. It protects against the modification of all data from the sender to any recipient.
- It will prevent hackers from posing as your VPN server and attacking you in an attempt to capture your data.
- It will always authenticate who the sender was that sent the particular data.
You will get VPN service with L2TP/IPSec protocol included with every package you order from CactusVPN.
