Remote access - VPN

Remote access extends the benefit of your network resources to mobile and home workers whilst allowing data to be consolidated at a central location.

Virtual Private Networks (VPNs) allow organisations to connect branch offices or remote workers to the corporate network, cheaply and securely. Whether you want faster or cheaper site-to-site communications or the ability to access your applications from a laptop or PDA whilst out of the office, we provide complete VPN solutions that are fast, cost-effective and extremely secure.

What is a VPN?
A VPN, or Virtual Private Network, is a network that uses the Internet for corporate data communication. Because access to the Internet is so cheap, a VPN provides a low-cost method of linking offices together and providing remote users with access to the corporate network. VPNs are particularly attractive for companies with international offices, since the cost savings can be enormous. Within the UK, the roll-out of ADSL means that even the smallest companies can now implement VPNs for affordable, high speed inter-office links and for remote users.

How does it work?
In the case of a VPN linking several offices together, each office will have its own VPN device. Each device encrypts network data destined for one of the other offices, and then sends it through the Internet to a corresponding device in the other office. This second VPN device in turn decrypts the data it has received, and sends it on to the office network just like normal data. In the case of remote users, VPN client software on their desktops, laptops and PDAs does the encryption before sending the data out to the Internet.

What sort of Internet connection do my offices need to access a VPN?
Offices linked together with a VPN normally have leased line or ADSL connections to the Internet.

What sort of Internet connection do remote users need to access a VPN?
Remote users can have any kind of connection to the Internet: modem, ISDN, ADSL, leased line, mobile phone, and wireless – if they can get to the Internet, they can use a VPN.

ADSL

Every once in a while we see the advent of new telecommunications technology which revolutionises how small and medium sized businesses do business, delivering new efficiencies and removing the barriers between you and your customers.

We are seeing it again because of the promises of the much-heralded online economy being brought to life through the advent of ADSL broadband technology. ADSL will enable you to take your business to new levels of professionalism and efficiency.

It will allow your business to enjoy a similar sort of online networking environment that major corporations are used to. ADSL is fast, giving you access to the Internet at speeds that don't even compare with traditional 28K or 56K modems.

Just imagine downloading and transferring large complex spreadsheets, heavily animated graphics presentations or multi-media in real time, without dial-up hassles, telephone line drop-outs and without tying up your phone line. Just imagine being able to have a live email connection or being able to network your employees and contractors across town, or across the country.

BT's ADSL based services do not affect the existing telephone line, customers can use voice and fax communications simultaneously or can make a telephone call whilst they are using your online services.

ADSL provides:

Ø      Faster 24hr fixed Internet access. Internet connections up to 10 times faster than using a current V90 modem connection with Instant email and Web access

Ø      Multiple user capability. Because of the bandwidth of ADSL, multiple users can browse the internet and send email with little performance difference.

Ø      Affordable. As ADSL is a fixed cost product, so it is not based on your Internet usage and provides predictable monthly budgeting
