VPN / SSL VPN

The types of Enterprise VPN Technology 2Secure provides are list in part below.

Virtual private networks (VPNs) enable corporations to use the Internet instead of private, leased lines, or dial-up lines to extend secure network connectivity or remote access.   Enterprise VPNs are those VPNs managed and deployed at the enterprise premises by the enterprise itself (i.e., IT staff) as opposed to VPN services managed by service providers. 

IP-based VPNs allow service providers and businesses to manage and protect intranets and extranets across the Internet, offering the same services, quality, and protection as on private corporate networks. In effect, VPNs leverage the Internet's strengths to improve cost savings, flexibility, and management relative to traditional Internetworking methods, though a VPN might also be employed over a pseudo-private link merely to ensure data security. 

The most basic VPN uses a technique called "tunneling" to send data packets across a public routed network. A VPN should also ensure security by encrypting data over a dynamic connection on the network. Beyond these functions, common features include user authentication, access control, and key management.

There are many possible configurations of a VPN, but there are essentially five basic types.

1. Remote Access VPN: Connects an individual person, often dialing in from home or a hotel, to a company's headquarters network. Remote access is the most common use of VPNs today.

2. Site-to-site VPN: A connection between a headquarters network and branch offices, particularly those in distant areas that would require long-distance connections with traditional network solutions.

3. Extranet VPN: Connects external entities such as suppliers, customers, partners, or other affiliated organizations to selected parts of a corporation's network. 

4. SSL VPN. 

5. SSL VPN (Tunnel Mode).

VPNs often include additional security functions such as firewall, anti-virus, content-scanning, and URL filtering, because the VPN is often located at a convenient choke point in the network.
