"The Subspace team will let us go even deeper with our security and data policies, enabling reliable corporate security policies, even when content leaves the Box platform to be accessed on a customer or partner's device," Box cofounder and CEO Aaron Levie said in a blog post.
Financial terms of the deal were not disclosed. Subspace's seven-member team will join Box, and Subspace will shut down its operations on April 3.
It was Subspace's containerized browser technology that drew Box's attention, for its ability to help manage access to cloud content from dispersed corporate and personal devices. Box plans to use the technology to extend its own security, compliance and control features.
With an eye on bring-your-own-device enterprise environments, Box has sharpened its focus on security in recent months. In addition to the security-minded service for financial firms, it recently rolled out Enterprise Key Management, designed to give businesses the ability to maintain exclusive control over the digital keys used to encrypt their data.
In December, it announced Box Trust and Box Enterprise Mobility Management, both also in the name of heightened BYOD security.
