Most IPsec VPN solutions require the installation of both special hardware and software for a user to gain access to the network. This is because IPsec works on the network layer of the Open Systems Interconnection (OSI) model and must be managed physically by network engineers rather than via software. A heavyweight technology, IPsec uses a combination of both hardware and software to mimic the qualities of a computer terminal connected to an organization's local-area network (LAN), allowing access to anything that an internal computer could. Whenever a browser or an operating system (OS) is updated, the newest version of the protocol is updated along with it.įor many years, VPNs relied on a technology known as Internet Protocol security (IPsec ) to tunnel between two endpoints. Users do not need to worry about updating the protocol on their browser either. Instead, the SSL VPN automatically uses the newest, most updated cryptographic protocol that has been installed on the user's browser.

Individual users of the SSL VPN do not have to decide which protocol to use for the VPN to do its job. SSL VPNs provide safe, secure communication via an encrypted connection for all types of devices, regardless of whether access to the network is via the public internet or another secure network.Īll traffic between a web browser and an SSL VPN device is encrypted with either the SSL or transport layer security (TLS) protocol. A virtual private network (VPN) is a service that allows a user to establish a secure, encrypted connection between the public internet and a corporate or institutional network.Ī secure sockets layer VPN (SSL VPN) enables individual users to access an organization's network, client-server applications, and internal network utilities and directories without the need for specialized software.
