Judith Hurwitz, an analyst with Hurwitz & Associates, agreed that making deep inroads into the enterprise won't be easy for Facebook.
"Very sophisticated security is mandatory," she said. "I am not sure that [Facebook] has put an emphasis on this. Obviously, the pricing model is established to get a massive amount of signups, but the question is, what is next? How do you manage users? How do you prevent a former employee from remaining on the network? How do you make sure that information on this environment meets regulatory requirements? There are a lot of questions."
There also needs to be built-in protection for individual company users and for corporate data, the analysts said, plus a space for private work groups and for sharing private documents.
Enterprises want more interaction and collaboration among employees, particularly those in far-flung geographies or working from home, said Dan Olds, an analyst with OrionX.
Many make do with tried-and-true technologies, like Skype, email, instant messaging and the good old telephone.
However, if Facebook is offering something that is better, easier and secure, companies may be willing to make the switch.
"This could turn into a big business for Facebook if they can answer the security and privacy concerns, but they'll have to do that before they see large and mid-sized companies sign up," Olds said.
