Internet Protocol Security (IPsec) is a suite of protocols and services that provide security for IP networks. It is a widely usedvirtual private network(VPN) technology. IP packets lack effective security mechanisms and may be forged, stolen, or tampered with when being transmitted on a public...
What is the L2TP VPN protocol? The Layer 2 Tunneling Protocol (L2TP) is a protocol that creates a secure tunnel for sending data between two points in a network. While it doesn’t encrypt data on its own, it’s often paired with encryption protocols like IPSec. L2TP is mainly used in ...
Internet Protocol security (IPSec) is a framework of open standards for helping to ensure private, secure communications over Internet Protocol (IP) networks through the use of cryptographic security services. IPSec supports network-level data integrity, data confidentiality, data origin authentication, ...
Traditional VPN protocol, such asGRE MPLS SR VPWS A virtual private wire service (VPWS), also called a virtual leased line (VLL), simulates the traditional leased line service by using an IP network to provide asymmetric and low-cost digital data network (DDN) services. From the perspective...
For businesses, the main alternative to OpenVPN is IPSec (Internet Protocol Security). This protocol doesn’t rely on SSL/TLS for encryption and requires a static IP address (which isn’t always suitable for a lot of IoT use cases). It’s regarded as a highly secure protocol, although it...

L2TP/IPSec – Layer 2 Tunneling Protocol is often used with IPSec to provide encryption. It is less secure than other VPN protocols but is widely supported and easy to set up. SSTP – Secure Socket Tunneling Protocol is a proprietary VPN protocol developed by Microsoft. It uses SSL/TLS encry...
A VPN tunneling protocol such as IPsec, GRE, L2TP, or PPTP must be configured on user devices. In this mode, Customer Edge (CE) devices initiate VPN connection requests, and VPN can be implemented without any special support of carriers. The CPE-based VPN brings complex configuration and ...
