The magic behind remote connectivity into the office

Do you find yourself unable to switch off when you leave your office every day? Maybe you need to remotely access files on your home computer whilst you are out on the road? VPNs are likely the most fitting solution for any small business or home office users.

What is a VPN?

A VPN (Virtual Private Network) is a method of remotely connecting to network endpoints across the Internet. Each endpoint of the VPN will have a private key which is used in the encryption and decryption of the data. This allows for the endpoints to act as if they are part of the same local network, even from opposite sides of the world.

What different types of VPN are there?

The main types of VPN are end-to-end and client VPNs. A client VPN is used primarily for a remote worker, such as a sales person who is on the road, or a home worker for a business with an office elsewhere, to connect in remotely.

This type of setup usually requires configuration to be done at the site that is going to be connected to, with the client-end using some type of software with a simple username and password to connect back.

A site-to-site VPN requires a bit more configuration – each endpoint will agree on pre-shared-keys and must also match their phase 1 and phase 2 encryption methods, in order for the VPN tunnel to come up successfully.

There are two main protocols that are used for VPNs – IPSEC and SSL. With each of these, there are different encryption methods that can be implemented, with varying levels of security.

How can VPNs be used to help your business?

VPNs can be used for an array of purposes. Some benefits of VPNs that may be of use to you include (but certainly aren’t limited to):

Remote access to services that would be available in the office
VPNs can allow you to access servers and services that would usually be available to you in the office, whilst you are working remotely. This can be beneficial for remote workers to access file servers, Customer Relationship Management systems and other in-house services.
Encryption of data across the internet
The encryption of data that is traversing a VPN tunnel allows for an extra layer of security when working remotely.
Split tunnelling
VPNs can be configured to send specific traffic via different routes; for example, corporate traffic can be sent via your company’s internet breakout, whilst other data such as domestic internet traffic can use another connection.

What technology do you need in place?

In enterprise solutions, devices such as a VPN concentrator are used to manage many incoming and outgoing VPN connections at once, but in small businesses and home offices, it is possible to configure VPNs directly on the router, so it is often possible to set up without the need for additional equipment.

Whatever the business requirement, Azera Technology have the solution for you.
