How Is IPSEC VPN Useful for Remote Users?
The IPSEC VPN is a virtual private network based on the Internet Security Protocol, given by a company to its users so that can access their servers from their location that could anywhere in the world. What makes it different is that, it utilizes the public internet without being intervened by the users of the public network and thereby keeping the data between the client and the company alone.
It is necessary that if you need an IPSC VPN connection then you will require a third party IPSEC VPN client software and hardware. To access the IPSEC VPN, the device must be installed with the IPSEC VPN client software. This feature is a con and pro at the same time.
The advantage is that, it offers security if the device on the client side is needed not just to be using the correct VPN client to join with the IPSEC VPN, but also required to be correctly configured. There are many problems that an intruder might have to face if he tries to gain access the network.
The disadvantage side is that, it is sometimes a financial load to preserve the client licenses and is also a terrifying dream for the technical support at the back hand to configure after installing the IPSEC VPN client software on all machines located in remote areas if it is impossible for them to reach the site and do it manually themselves.
It is again a disadvantage that is usually known as the advantage of the competitors for the Secure Sockets Layer (rival SSL) VPN solutions. Most browsers have inbuilt SSL capabilities. It is just a common protocol. So nearly each system across the globe is pre-equipped with the important free IPSEC VPN client software to connect to the SSL VPN.
Adding to its advantage is that they permit for more accurate access operation. They supply tunnels or pipes to particular programs and not just whole of the corporate LAN. This way, SSL VPN users are allowed to use only those applications that are already configured to be accessed than the complete network. Next, it is simpler to give variety of access rights to unlike users and have better control over network accessed by users.
The bad side of the SSL VPN is that they only work for applications that are web based if you use them via a web browser.
