Secure information sharing and the data residency dilemma

One of the top priorities for companies today is information sharing with a vast ecosystem of external entities, ranging from business partners and suppliers to customers.

There are dozens of technologies for information sharing, and they generally approach the problem in one of two ways. The first approach extends the infrastructure at the network level, using tools such as IPsec virtual private networks (VPN) and leased lines. These technologies create significant security challenges when extending network access to partners, customers and suppliers.
