What is a Financial Extranet?

Also known as: Colt PrizmNet

An extranet is a private network used by organisations to provide external partners and other trusted third parties with secure and controlled access to their internal applications, processes and information. Colt’s financial extranet, PrizmNet, connects exchanges and other providers of financial content (including market data, research and other services) to an ecosystem of over 10,000 capital markets firms worldwide.

Colt’s financial extranet facilitates direct cloud connectivity by interconnecting with the nearest PrizmNet PoP or through our extensive network connecting 29K+ buildings & 900+ data centres to connect to multiple third party organizations.

These interconnects, which also underpin Colt’s award-winning Dedicated Cloud Access proposition, provide resilient and diverse connectivity to leading Cloud Service Providers (CSPs), and dedicated bandwidth between CSPs and the Colt PrizmNet network. Connectivity to new third party organizations can then be ordered through the Colt PrizmNet portal,and implemented in a matter of days.
