extranet? What is that exactly?

As an extension of the intranet, an extranet is only accessible to a specific group of external users.An extranet uses the technical solutions of the Internet, but is not necessarily connected to them.It can also be set up as a completely separate network.Users can only access this form of extranet via a leased line or direct dial-in.This gives a privileged group of users secure access to certain data without having access to a company’s entire intranet.Installation via the Internet is also possible.In this case, a “Virtual Private Network” (VPN) is the most common form.The private connection is tunnelled through the public network.Efficient encryption systems make this system secure.Working with an extranet is particularly interesting for companies.You can give a defined group of users secure access to specific data.This gives customers or business partners access to data that should remain hidden from the public.At the same time, sensitive company data remains securely protected.This structure also protects very well against attacks by hackers.Due to the high level of security, an extranet is ideal for exchanging data beyond company boundaries.The fast access and the protected space also predestine the medium for communication between different offices and branches.Geographical distance no longer matters and the data is safe from unauthorized access.The extranet supports communication along the entire value chain and saves time.Every time saved is worth hard cash in today’s economy and represents a competitive advantage that should not be underestimated.You can find more information about the Extranet here – exactly?
