SSL VPN/Dual factor authentication is helpful when a user wishes to secure access to corporate networks and cloud applications. This is achieved by protecting identities of users, and ensuring that a user is who he claims to be. An SSL VPN does not require the installation of specialized client software on the end user’s computer. A virtual private network (VPN) provides a secure communications mechanism for data and other information transmitted between two endpoints. An SSL VPN consists of one or more VPN devices to which the user connects by using his Web browser.
