Enterprise File Sharing

White Paper
With existing file servers and Active Directories that you have, why not simply cloud enable them for mobile access and file sharing over the Internet for your employees, while keeping all the permissions and security controls in place?

The Challenge

Your employees may look to the cloud as they face difficulties accessing traditional file servers from mobile devices. They may already use some consumer file sharing and sync solutions such as Dropbox or Office 365 and using those solutions in an ad-hoc way to solve temporary file sharing needs from here and there. Company files may have been copied out to a personal Dropbox folder for easy sharing or may have been sent over emails as attachments for easy access when it is outside of the company firewall. Without knowing exactly where are the files, it is a pretty severe data security problem.

As if data security was not a big enough problem, leaking file server data to a 3rd party service is a major problem too. Businesses can't control where the files are. Nor can they control who has access to once the data ownership change hands.

The Solution

Employees love Dropbox because it is so simple to use as compared to traditional VPN (virtual private network) ways of accessing data on company file servers. A ban on Dropbox won't be effective unless there is an easier alternative solution that address the data ownership, data security and data privacy problems. CentreStack provides a way for you to maintain control by leveraging your existing file servers as data repository and your existing Active Directories as identity service provider for the enterprise file sharing solution that is similar to Dropbox.

After the CentreStack server is deployed, employees can use web browsers, mobile applications and even PC and Macs to access existing file shares. On PCs, the familiar locally mapped drive interface and file locking behavior are preserved. The process is so seamless that users generally require no downtime and minimal, if any training.

Solution Highlights

Gladinet CentreStack server can be installed and deployed on-premise as a private enterprise file sharing server. The private enterprise file sharing service can integrate with Active Directory user identities and integrate with existing file server shares. Users from internal employees to remote employees and external clients and partners can share files and folders based on the current file server content and follow certain predefined security rules and permissions.
Installable Sync and Share

Gladinet provides a Windows Installer package that creates private enterprise file sharing servers based on Microsoft server technology. It’s easy to install, manage, and scale. The installation time is short with a few clicks from start to finish.

Active Directory Integration

Automatically use existing identities and home shares from Active Directory. Existing NTFS permissions on file and folders are checked natively by the Windows Operating System.

Complete Control

The entire solution can be deployed and managed on-premise. Every component is under control from the backend file servers and Active Directories to front end agent softwares on user's devices.

DFS Integration

Leverage DFS or any other local storage service as data repository, whether it be D: drive or E: drive from local disks or from iSCSI interface or file shares from local area network.

Online File Server

Provide remote HTTPS (SSL) web access to files stored behind the firewall using any device without using a VPN or public cloud.

Amazon, Azure, OpenStack Integration

Create a private sync and share solution based on object storage like OpenStack Swift, any S3 compatible, Microsoft Azure and more.

Challenges without Enterprise File Sharing

Without providing an enterprise file sharing service to employees, the employees may select consumer cloud file sharing solutions like Dropbox to share files. Dropbox may provide productivity and cost benefits but often fail to provide comfortable answers to questions like, “Where, exactly, is my data? Who has access to it? What will they do with it?” And these concerns don’t just involve cyber-threats and hackers but competitors, foreign nationals, and even governments.

As if uncertainty about the data ownership situations is not enough, IT administrators must also consider the following implied directives:

Migration Pressure

Avoid being forced to the cloud as users combine tools like Dropbox, Google Drive and Email.

Big Folder

In old days, it takes time and also quite cumbersome to turn a big folder into a zip file to transmit over Internet.

Data Sprawl

Avoid the headaches of data sets split between internal file servers and cloud solutions like Dropbox.

Migration Costs

Avoid the cost of manual replication or recreation of NTFS permissions.

Version Control

Avoid data fragmentation that creates multiple versions of files that are difficult to track.

Security Threats

Eliminate threats from de-centralized security and personal cloud accounts.

CentreStack eliminates the common drawbacks of traditional file server access and cloud collaboration/folder sharing solutions.

Guarantee Data Privacy

Businesses can address data privacy concerns by using CentreStack to provide access to internal file servers. It’s common to talk about replacing existing file servers with cloud solutions to reduce costs and administrative overhead, and CentreStack can facilitate that in any private cloud, but CentreStack offers the unique option of using existing file servers to replace cloud file sharing!

Mobile Access to File Servers

Simplify remote access to file shares with familiar interfaces on any computer or device. Windows and Mac desktops display natively mapped drives in Explorer and Finder. That same experience is presented on iOS and Android devices like iPads, iPhones and Pixels or can be viewed from popular web browsers like Chrome, Firefox, and Internet Explorer.

Simplify Collaboration

Easily collaborate with business partners by providing them with access to a limited set of internal files or folders. Share files with non-AD users while maintaining administrative controls. Simplify multi-site collaboration with automatic version controls and file locking.

Reduce Costs with a Simple VPN Alternative

Eliminate the overhead and support tickets commonly associated with VPN file sharing, Always On VPN or Direct Access. Automatically use existing users and permissions to save setup time and money.

Simplify Management

Centrally manage users, access controls, and storage for each tenant. Easily keep track of where the data is, who has access and how it’s being shared.

Centrally Manage Granular Folder Permissions

For complete control and visibility, permissions can be managed from the file server that was their source, or natively with CentreStack.

Maintain Compliance

Centrally manage users, access controls, and storage for each tenant. Admins can perform audits of GDPR and HIPAA compliance or keep track of any changes that have been made to individual files.

Increase Productivity

Provide an always-on mapped drive that works anywhere on any device and allows mobile users to easily access internal file shares or cloud file servers

Enhance Data Security

Files are secured at rest and in transit with military grade encryption, secure connections and more. Automatically use existing users and permissions to save setup time and money.

On-Demand Synchronization

Mapped drives display directory structure but delay downloads until a file is used to reduce bandwidth usage and endpoint storage consumption.
