2 Secure File Sharing Service Models

Simplify File Server Access with a self-hosted file sharing solution that keeps data in file servers on-premises and does not replicate data to the cloud. This allows IT professionals to satisfy increasing needs for remote access, collaboration and productivity without being forced to compromise data privacy and security.

Self-Hosted File Sharing in a Private Cloud takes advantage of cloud economics and infrastructure without sacrificing privacy and control. For example, managed service providers (MSPs) often prefer to provide their own white labeled file sharing solution to take care of data ownership, data privacy and data security for their clients.

Challenges of Public Cloud File Sharing

Traditional cloud file sharing solutions like Dropbox, OneDrive, ShareFile 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.

The bigger the company, the better they may make you feel the data is secured with their hosting. However, services such as Dropbox and iCloud have been breached despite spending enormous technical resources implementing secure file sharing for business. The problem is that security is a relative term and depends on many factors such as the threat model; how much attention hackers have placed on the service; and where the weakest links may be found.

This is why public file sharing services become a victim of their own success. The more widely they are used, the bigger the target. The more users logging in, the more security practices get reduced by the worst actors. As an enterprise IT professional, it can therefore be safer to self-host a corporate file sharing solution and secure it based on internal corporate standards.

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, SharePoint and Email.

User Training

Avoid the high costs of re-training users when they are already familiar with mapped drives and file locking.

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.

Use Cases

Cloud migration may seem increasingly inevitable, making it difficult to manage the tensions between productivity benefits and data privacy threats. But CentreStack offers a solution for thought leaders seeking to simplify the way people work without compromising data privacy.

Whether it's secure sharing for on-prem and remote workers, external clients, partners or guest users in general, CentreStack has the flexibility to provide a great solution!


CentreStack eliminates the common drawbacks of traditional file server access and cloud file 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 file shares 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.

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. Administrators 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.

White Labeled File Sharing Solution

CentreStack provides a white labeled platform that makes it easy for MSP partners to build a private cloud file server solution based on infrastructure from Amazon, Azure or Wasabi.

On-Premises Alternative to Dropbox and SharePoint

CentreStack has the flexibility to provide an on-premises alternative to Dropbox and SharePoint using existing file servers.
