Is peer-to-peer secure enough for corporate use?

Peer-to-peer technology is being used more frequently for corporate activities. Many large vendors are beginning to integrate P2P applications with the core business programs they sell, such as their customer-relationship management systems. If vendors agree on a solid, standards-based, widely supported infrastructure that provides interoperability and platform independence, corporate P2P adoption could increase even more. However, now that P2P is being used for more important functions, security has become a critical issue.
