IPsec VPN Overview

A VPN provides a means for securely communicating among remote computers across a public WAN such as the Internet.

Security Director simplifies the management and deployment of IPsec VPNs. In general, VPN configurations are tedious and repetitive when deploying over a large number of SRX Series devices and for full-meshed VPN deployments. With Security Director, you can use VPN profiles to group common settings and apply them to multiple VPN tunnel configurations across multiple SRX Series devices. You can mass deploy site-to-site, hub-and-spoke, and fully meshed VPNs. Security Director determines the necessary deployment scenarios and publishes the required configuration necessary for all SRX Series devices.

Security Director supports policy-based and route-based IPsec VPNs on SRX Series devices. Policy-based VPNs are supported only in the site-to-site deployments, where you configure two endpoints. If you have two or more SRX Series devices, then route-based VPNs offer more flexibility and scalability. You can select between site-to-site, full-mesh, and hub-and-spoke for route-based VPNs. To allow data to be securely transferred between a branch office and the corporate office, configure a policy-based or route-based IPsec VPN. For an enterprise-class deployment, configure a hub-and-spoke IPsec VPN.
