It's really easy for my users. I can just tell clients, go to your "M" folder, all your files are there. They just get it. They can also download the app on any mobile device - it's just really simple to set up and to use. It's also easy to manage and easy to sell.

Simplify Remote Access to File Servers

With a self-hosted secure remote access solution that keeps data in file servers on-premises and does not replicate data to the cloud, CentreStack allows IT professionals to satisfy increasing needs for remote file access, collaboration and productivity without being forced to compromise data privacy and security.

As more and more businesses shift to work-from-home arrangements, simplifying secure remote file server access for mobile workforces could be critical to maintaining productivity.

Simplify Remote Access to File Servers


Web and Mobile Access

Modern workforces prefer Dropbox-style or OneDrive-style file sharing methods, which promote a mobile-first design with responsive interfaces for web browsers and mobile applications. The mobile-first design makes users believe that files always follow them around and readily available at their fingertips.

Boost remote worker productivity and simplify remote access with a combination of features like drive mapping, file locking, version control, and modern, mobile-first web browsers and mobile applications.

Remote Access to Files has Some Challenges

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.

CentreStack provides a compelling alternative to VPN-based access by publishing file shares over HTTPS/SSL and, at the same time, providing desktop agents and mobile applications for a complete end-to-end access solution. This makes it really easy for users to remotely access internal file shares while they're on the go without compromising security. In fact, security is increased because administrators only need to provide access to the specific file shares a user can access. This presents a smaller attack surface to hackers since the entire network need not be exposed to each authorized user.

Remote Access Server

CentreStack adds secure remote access and file sharing, disaster prevention and recovery, to file servers on-premises with easy cloud migration to private cloud storage. It is the real cloud file server solution you have been looking for!

Remote Access

CentreStack bridges file servers and cloud storage for secure remote access without the need for a VPN.

Web Access

Accessing files and folders directly from within a web browser as if it is as interactive as from a desktop drive.

Mobile Access

CentreStack leverages cloud storage for secure mobile file sharing from a web browser or a mobile application.

Hybrid Access

CentreStack sets up a hybrid deployment between local file servers and cloud storage that can be seamlessly converted to cloud-only.

Remote Agent Access Over HTTPS/SSL

How-it-works Diagram


Remote file access without a VPN

Step 1: Log in

Users enter existing Active Directory (AD) user name and password on any supported client.

Step 2: Secure Channel

Credentials are passed securely over HTTPS to the CentreStack server.

Step 3: Firewalls

The external firewall only needs to open port 443 for HTTPS traffic.

Step 4: Active Directory

CentreStack finds the user's tenant and passes the credentials to the corresponding AD domain controller.

Step 5: Remote Access

CentreStack uses the authentication token from the domain controller to access internal file shares.

CentreStack Security Benefits

By keeping files on the hosted file server and maintaining Active Directory and NTFS permission, productivity is increased without sacrificing security!


Data stays on hosted file servers. Existing permissions govern remote access. Data privacy is further maintained through isolated management of users and access rights in each tenant.


Use existing AD users and NTFS folder permissions with a simple interface to identify remotely accessible file shares that automatically appear in the user's mapped drives.


CentreStack allows admins to run HIPAA or GDPR compliance checks and generate reports demonstrating compliance for file access and collaboration.

Productivity Benefits

Enhanced productivity for remote workers and mobile devices with on-premise control and security!

CentreStack has desktop and mobile applications. Unlike VPN, which is a generic network technology, CentreStack has applications on the endpoint device ready to help with file and folder access.


Files are cached locally, so access feels instant without the tedious setup of remote desktops or VPN file sharing. Users get the benefit of local performance while working remotely.


Legacy applications may continue to use the original file shares, which remain unchanged as CentreStack provides remote access to the same file shares from any device.


Minimize user training with a mapped drive that works the same on-premises or remotely. Provide a seamless local experience for users even when they are offline.

Core Value


The remote access 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 is the data repository for the newly added remote file access service. For employees, the files at work are the same files available remotely on mobile devices.


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


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

Permission Control

The same NTFS permissions in place to protect the internal Windows file server files will be the same permission control to protect the remote file access service.

Remote File Access Features

Boost productivity for mobile workforces when they need to remote access corporate file servers.

Multi-Site File Synchronization Common Features

Drive Mapping

Users have the familiar drive mapping interface for remote access to files.

File Locking

Global file locking facilitates team collaboration by locking active files that are being edited.

Endpoint Protection

Files and folders from corporate file servers cached on remote devices are subject to encryption and remote wipe.

Cloud Backup

Folders from edge devices can be back up to central corporate file servers and also on-ramp to the private cloud.

Cloud Drive Mapping Highlights

Folder Permissions

Define different permissions for folders at different levels of the directory structure or inherit from NTFS permissions directly.

Mobile File Sharing

Web browser-based file managers and mobile applications make web and mobile access to files easy.

User Rights

From internal Active Directory users to external clients and partners, you can define user rights for folder sharing.

Version Control

Shared folders are put under version control, and notifications are available for users subscribed to the folders.
