Remote File Server Access

Simplify remote file server access and remote file sharing for mobile workforce. A file sharing server enables remote file access from web browsers, remote PCs, Mac and mobile devices , all without the need of a VPN!


VPN vs. Mapped Drive over HTTPS ??

Virtual Private Networks (VPNs) have been the traditional answer for secure remote access to network file shares on internal file servers. But they tend to be difficult to support and manage. Users often have trouble connecting to the file server from mobile devices or complain about other connectivity issues and slow performance. In addition, VPN is also very clumsy to use. First the user had to click on a VPN icon on the device to setup a virtual circuit back to the corporate network, and then locate the file shares, map a network drive before accessing files and folders.

VPN is a Support Headache

First, end users have to understand file servers, network, mapped drive and various technical terms. Secondly, they frequently call in to help desk support about their VPN issues.


Ad-hoc File Sharing Creates Issues too

When Virtual Private Networks (VPNs) are hard to use, users turn to ad-hoc ways to share files and folders over the Internet remotely. Email attachments are one of the most popular way and using personal Dropbox accounts is another way. However these ad-hoc ways of doing remote file sharing create many problems. First problem is that it is harder for businesses to maintain compliance to regulations regarding where the files are stored and shared. Second problem is that, over a period of time, it becomes a challenge to understand where is the latest version and who has the right version.

Others Create Data Sprawl

Email attachment is not efficient and personal Dropbox accounts duplicate files. Over time, data is splitting among different data silos.


Mapped Drive over HTTPS!

At work we access Windows file servers from mapped shared drives. When we're in the office our tasks include accessing files and folders from Windows explorer, on a mapped drive letter and sharing files with co-workers. These shared drives from the Windows file server are reliable and productive.

But when we leave the office, it's not so easy. The VPN is slow, problematic and unreliable. FTP and WebDav are no help and even worse than a VPN. Email attachments generate large zip file and are likely to get blocked.


Private File Sharing Server

You can think of CentreStack as a private file sharing server that setup cloud drive mapping over HTTPS, in addition to web browser interfaces and mobile applications. 

With CentreStack, your Windows file servers are empowered with new cloud-style remote file sharing and remote file access capabilities combined into an easy to use mapped drive connected over HTTPS (SSL protocol). As a result, your mobile workforce will enjoy modern remote file access powered by on-premise file server security and its shared drives. In other words, their experience is the same in the office or away with added cloud features.

From Internal Shared Drives to Remote File Sharing Server

Most businesses leverage Windows Server IT infrastructure with Windows file server network shares and Active Directory. At work, we access shared drives. But when we become road warriors or work-from-home employees, how convenient would it be if the shared drives at work continue to work from remote locations without a VPN while still governed by the same security principles and identity providers from work?

Let's add modern remote file sharing and remote file access capabilities to modernize the Windows file servers we love!


CEO Access Reports

Accountants work on QuickBooks on corporate file servers and close the book for the month. The financial reports are generated and saved to "reports" sub-folder on the file server. CEO gets the notification and use his iPhone to check the financial reports directly with remote and mobile file accessing capabilities without the need of complicate VPN setup.


Real Estate Takes Pictures

Real estate agents going out to the houses in the market and take pictures of the house on their iPhones and iPads. The pictures are uploaded to Amazon S3 as the company's centralized media folder. Graphical designers back at the head quarter use a s3 mapped drive and Photoshop to enhance those house pictures before the house is posted for sale with nice picture presentations.


Share CAD Files

CAD software such as AutoCAD or SolidWorks running on corporate file servers and produce blueprints and other type of construction related PDF files in a sub-folder on the same file servers. Field engineers with mobile devices such as a remote laptop or iPad can access these files from remote locations easily without the need of using VPNs. Some of them work in offline access mode to take pictures and other files back to corporate file servers remotely over HTTPS.

Core Value


The folder sharing solution extends the current internal Windows file server's reach to remote locations via HTTPS and web protocols. It is privacy by default.


The internal Windows file server and existing IT infrastructure, including the new CentreStack server are owned by the same corporation and the files and folders on the file server are privately owned. 


The internal Windows file server is the data repository for the newly added private folder sharing service. For employees, the files at work are the same files available remotely on mobile devices.


Since files never leave the current on-premise file servers, it is much easier to pass compliance auditing. The new private file sharing server is the only component that need additional work.

Permission Control

The same NTFS permissions that was in place to protect the internal Windows file server files will be the same permission control in place to protect the private file sharing service.

Remote File Sharing Server Benefits!

Cloud-style mobility and local file server security working together in a unified fashion.

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, Edge and Internet Explorer.

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. Windows file server network shares and shared drive can be turned into online shared folders guarded by the same security measures as those from on-premise file servers and governed by the same Active Directory.

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. When files and folders can continue to stay-in-place with the Windows file servers, the security parameters are smaller and simpler than a public online sharing services and easier to pass compliance tests.

Simplify File Share Access

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. Mobile workers will see the same content in the online shared folder as if they were from internal mapped drive.

On-Demand Synchronization

Mapped drives display directory structure but delay downloads until a file is used to reduce bandwidth usage and endpoint storage consumption. Shared folders and files also have generated web links allowing them to be shown in a web browser based file manager. The files will not be actively downloaded or viewed (as in secure-data-room) until users generate access intents.

Reduce Costs with a Simple "VPN"

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. Internal shared drive, with the help from the CentreStack server, have new online folder representations over HTTPS (SSL) protocols and with RESTful APIs for client agents and mobile applications.

White Labeled File Sharing Solution

CentreStack provides a white labeled platform that makes it easy for MSP partners to build a private online file sharing solution based on infrastructure from Amazon, Windows Azure or Google Cloud. MSPs can even build the white labeled solution inside their most preferred data center on a per-client basis with per-client branding support.

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. There is a centralized web-based management portal that provide single-pane-of-glass-style management console to manage shared folders and shared files in addition to other objects in the management scope.

On-Premises Alternative to Dropbox and SharePoint

CentreStack has the flexibility to provide an on-premises alternative to Dropbox, OneDrive and SharePoint using existing file servers. You can modernize your file server so much that from the online file sharing solution's perspective, it is same as those from public domains, while at the same time, the solution keeps all the file server security and data ownership benefits.

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. Businesses and their employees accumulate the NTFS permission structure over years of active use and practice. Those NTFS permissions will be inherited by CentreStack and continue to control access to online folder sharing.

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. It is so much easier to pass compliance tests when both the CentreStack servers and the Windows servers IT infrastructure are under your supervision and control.
