Secure File Sharing

White Paper
Why wait for security assurances from 3rd party cloud solutions? Self-host a private file sharing solution from your own file server. Trust yourself and your infrastructure!

Secure File Sharing Strategies

Are iCloud and Dropbox secure? They have enormous technical resources implementing sophisticated security measures such as encryptions for data protection but have still failed to protect their customers data. 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 file sharing solution and secure it based on internal corporate standards.

Solution Highlights

Gladinet CentreStack server can be installed and deployed on-premises as a private file sharing server. The private file sharing service can integrates with Active Directory user identities and existing file server shares. Internal and remote employees, external clients and partners can share files and folders based on the current file server content, security rules, and permissions.

Installable Sync and Share

Gladinet provides a Windows Installer package that creates private file sharing servers based on Microsoft server technology. It’s easy to install, manage, and scale.

Active Directory

Automatically use existing identities and home shares from Active Directory.

Complete Control

The entire solution can be deployed and managed on-premise, from private cloud storage to orchestration to clients.

DFS Integration

Leverage DFS or any other local storage services.

Online File Server

Provide remote access to files stored behind the firewall using any device without using a VPN or public cloud.

Amazon, Azure, OpenStack Integration

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

Challenges of No File Sharing

Without providing a private secure file sharing service to employees, they may opt for 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.

And 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.

Large File Transfer

Sharing big folders as email attachments can be cumbersome and slow.

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.

Secure File Sharing Feature Highlights

CentreStack eliminates the common drawbacks of remote file server access and cloud collaboration solutions and provides the best of both worlds – the privacy, security and control of legacy file servers combined with the efficiency and productivity gains of cloud collaboration.


CentreStack integrates with Office 365 for web-based co-editing and co-authoring.

Large Folder

Use Outlook integration to transfer large folder or files as web links via email.

Link Sharing

Use web links to share files and folders with recipients or to receive files.

Folder Permissions

Define different permissions for folders at different levels of the directory structure.

Secure Data Room

Web based secure data room allows view-only access with download disabled.

User Rights

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

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 private 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 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.

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.
