The two-year-old startup based in Toronto, announced the acquisition in a blog post  but terms of the deal were not disclosed.

Airpost will close operations oat teh end of February, and customers won't be able to use its product after that, founder and CEO Navid Nathoo said in an email message.

Airpost works by telling IT departments when employees start using cloud-based apps on their own and provides access controls and protections against potential vulnerabilities in those apps. The idea is to let employees keep using the apps they found and get the productivity they want, while keeping the enterprise secure.

The acquisition could be a good fit for Box, which has a cloud-based file-sharing platform that individuals can use but aims its business at large enterprise accounts. Box still offers a personal service with 10GB of free capacity, while boasting marquee clients like GE, DreamWorks Animation and pharmaceutical company AstraZeneca. The company raised about US$175 million in its initial public offering last month.

The 10-year-old Box is up against larger rivals that offer inexpensive storage and collaboration services such as Google Drive and Microsoft OneDrive for Business while making most of their money elsewhere. But Box also integrates its platform with other tools, including Microsoft Office 365.
