The availability of cheap, easy-to-use and accessible cloud file-sharing services means users have more freedom and choice than ever before.
Dropbox pioneered simplicity and ease of use, and so quickly picked up users inside the enterprise. Similar services have followed Dropbox's lead and now there are dozens, including well-known ones such as Google Drive, SkyDrive and Ubuntu One.
Filks said: “Enterprise employees use Dropbox and Google because they are consumer products that are simple to use, can be purchased without officially requesting new infrastructure or budget expenditure, and can be installed quickly on your own device without the involvement of IT.”
But, IT departments have become concerned about the security of uploaded corporate data, especially as compliance requires knowledge of and control over the data's location. In addition, many consumer-grade services do not provide the kinds of features that enterprises need.
Analyst Greg Schulz of StorageIO said the problem with consumer-grade cloud file sharing services is not the technology per se but their usage: “Generally speaking, at least for the sites with good security, identity access management and other safeguards, it’s not that there is anything wrong with the technology, rather how it might be used or abused.”
Filks said: “Lack of security is the main issue, this includes data protection, ID and password management. Security and FSS [file sync and share] are diametrically opposed; security restricts access whereas FSS provides access to information.”
Filks explained the tension in the enterprise: “Users want something simple to use that does not cost them any money and they do not want to be responsible for any management or security.”
“But, the IT infrastructure people want the system to be secure and highly available, which includes business continuity, a thought-out roadmap of how the present FSS solution can be upgraded to the next and the usual documentation. They want to know if the system is performing correctly, where the bottlenecks are, security audit trails etc.”
Wild Beauty goes for Dropbox cloud file-sharing
Wild Beauty is a distributor for Paul Mitchell hair care and styling products in Germany, Austria and beyond. Its team of around 90 internal staff and educators needed access to information about the latest products while the salesforce needed to be able to take these on the road to show prospective customers.
The company tried USB sticks, email and FTP sites but they all proved too difficult and clunky so the company opted for an online shared storage service.
“We looked at lots of services, but we focused on Dropbox for Business based on its usability and ease of use, plus the cross-platform compatibility with PCs, Macs and mobile devices,” board member Noah Wild said.
“This means we don't need to spend much time teaching people how to use the tools, even older members of the salesforce who have been on the road for 30 or 40 years.”
As well as the self-training that users had already done, another plus point was the number of third-party developers for Dropbox.
“The ecosystem is more advanced than the competitors,” Wild said. “There's a PDF tool we have integrated into Dropbox which is easy to use. And our educators use DropVoice which allows us to share voicemail messages. It was easy to integrate these tools, and it was cheaper too.”
From an enterprise integration perspective, Wild considered integrating Dropbox users with Active Directory (AD) but decided this was not needed, mainly because a significant proportion of the workforce is freelance and so not in the AD system.
“We liked the way that even though we are not a large enterprise, Dropbox listened to us and helped us achieve what we wanted,” Wild said. “It's nice to see them taking notice of us as a mid-sized business.”
