Citrix sent out word this week that it’s buying Zenprise, a firm known for its enterprise BYOD solutions. Terms of the deal were not disclosed but we can speculate it was substantial transaction: Zenprise raised $64.5 million in venture capital prior to the acquisition.

Sumit Dhawan, the head of mobile for Citrix, explained the reasoning behind the deal from his company’s perspective.

“Consumerization and BYO have given rise to very difficult challenges for businesses in enabling a productive, mobile workforce while still maintaining tight controls over company information. Zenprise was a clear choice for Citrix, with its leading MDM product, an experienced team, a history of innovation, and a footprint on more than one million devices. With a complete Citrix enterprise mobility solution, customers have all the necessary pieces to manage and secure mobile apps, content and devices.”

Citrix says that it intends to integrate Zenprise’s flagship platform with its CloudGateway mobile management solution and Me@Work, an application-centric remote access tool designed for SMBs.

BYOD has become something of a self-inflicted phenomenon in the workplace. Enterprise can’t really stop one fifth of their users from sharing files on Dropbox via their phones, but they can alleviate the situation by enforcing corporate policies. And the best way of doing that  is turning to vendors like Zenprise.

The startup went through a hyper-growth stage in the past year and half, hiring all-star executives and more recently securing a $30 million funding round.  Citrix probably didn’t bag it for a barging price, but then again the desktop virtualization giant reported revenue of over two billion dollars in 2011. It could certainly afford the price tag, but it has yet to have been  seen if the company can realize a return on this latest investment.
