IPSec VPN in more detail

IPSec based VPNs

IPSec, which stands for Internet Protocol Security, is a solution that addresses the issues relating to the security of data being sent across the Internet. In reality, it's a complex suite of industry standards defined by the Internet Engineering Task Force (IETF), with the assistance of many vendors, to tackle data encryption and integrity. In practice, it's a tool users of the Internet can employ to ensure the security of data and the authenticity of the sender when transmitting and receiving information across public networks such as the Internet.

A Total Security Gateway Solution

NetPilot's accredited firewall is further enhanced with the addition of both OpenVPN and IPSec. As well as providing total security for the local network, NetPilot can offer the same security for data traveling between networks across the Internet.

What NetPilot offers

The most common use of IPSec and OPenVPN is to provide site-to-site connectivity, but NetPilot VPN's implementation also provides remote access to, and administration of, remote NetPilot units and associated local networks. All these functions are achieved at low cost - using the Internet - and are totally secure, to protect against electronic eavesdropping and man-in-the-middle attacks.

Virtual Private Networks

By incorporating IPSec and OpenVPN, organisations can establish totally secured communicatios between their sites using existing Internet connections. A labyrinth of secure networks can be established in no time at all without the cost of expensive permanent site-to-site connections or the disruption caused by cabling installation engineers. And what's more, other Internet activities, such as web browsing and the transferring of email to and from other destinations around the world, can still continue in conjunction with this.

If your sites already have permanent connections to local Internet access providers, then you need no more than a NetPilot unit at each site to establish totally secure Virtual Private Network.

Remote Email Access

NetPilot also provides the functionality to remotely access email on NetPilot or an office mail-server on its LAN, from anywhere in the world. From home or hotel, an office network is securely accessible. All that's required is an NetPilot installed at the office and a permanent Internet connection. A suitable IPSecor OpenVPN client installed on the PC or Notebook being used to remotely access the NetPilot is also required - side bar for link to information on clients.

Remote Administration

NetPilot and the network resources it protects can be securely administered over the Internet from remote locations. Support centres can easily administer many NetPilots simultaneously over a single Internet connection. Even network resources located behind NetPilot could be securely supported. All that's required is a NetPilot unit, and ensure that it has a permanent connection to the Internet.

24 by 7 by 365 couldn't be made easier either. Out of hours support for customer and client NetPilots, and local network resource could be provided by engineers located at home if their PC is equipped with a suitable IPSec client, and they have local access to the Internet. (note - client may not work through local router or firewall)


As IPSec is the de facto standard used by virtually all vendors of firewall and Internet security devices, it allows for interoperability between these products. NetPilot VPN's IPSec implementation should enable it to establish a VPN with other vendors' products supporting IPSec with 3DES encryption.

Performance characteristics

As with any Internet connection, the performance seen by a user depends upon many factors, which include the size (bandwidth) of the local Internet connection, the size of the Internet connection at the remote site, the number of other simultaneous users at both sites, and the quality of all connections in-between. It should be noted that NetPilot does not limit the number of active configured tunnels.
