The protocol used on the VPN can be one of the IPSec (Internet Protocol Security) Internet Protocol Security or SSL (Secure Sockets Layer) protocols. They are VPN types according to the purpose used and the desired level of security.
SSL VPN (Secure Sockets Layer Virtual Private Network) is defined as “Secure Sockets Layer Based Virtual Private Network”. In addition to remote access to corporate networks and facilitating information sharing, it is aimed to increase efficiency by reducing the cost in terms of use of resources.
IPSec VPN (Internet Protocol Security Virtual Private Network) “Internet Protocol Security Based Virtual Private Network” provides a secure connection with the IPSec protocol it contains. However, the difficulties in its implementation and its high cost make it difficult to use this technology.
For this reason, IPSec VPN has lost popularity to SSL VPN technology, which is easier to manage and more economical.
SSL VPN can be used to encrypt any protocol at the application layer level. It is a type of VPN that works with the Secure Sockets Layer (SSL) protocol and can be accessed via web browsers and HTTPS protocol. Although HTTPS is known as the most common web communication encrypted with SSL, it has a wide range of uses such as POP3 and FTP protocols encrypted with SSL.
SSL VPN technology allows a secure connection to a network by using internet browsers provided by operating systems without the need for software or hardware on the user’s part. Especially in institutions with many external users, ensuring the healthy operation of the VPN software in each user means a great service load for the institution. In addition to being easy to set up and manage, it also provides the security of the connection, making it more preferable than other VPN types.
