On Premise File Sharing

On premise file sharing solution allows businesses to self-host private file sharing servers with their on-premise IT infrastructure for easy mobile access and secure file sharing to on-premise file servers.

Challenges of Consumer File Sharing

As businesses move more employees to remote work arrangements, employees need a suite of remote working solutions to be productive. One solution is corporate file sharing, related explicitly to accessing existing on-premise file servers from home-offices.

Without providing a company-wide private file sharing solution, employees may select consumer cloud file sharing solutions like Dropbox. This approach leads 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.

IT administrators must also consider the following implied directives:

Challenges IT Administrators face:

Migration Pressure

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

Large File Transfer

Avoid the challenges of sending large email attachments or converting them to zip files for Internet transmission.

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.

From On-Premise File Servers to On-Premise File Sharing

Accessing shared drives at work is usually based on Windows file server network share and Active Directory, principal components of enterprise infrastructure. But when we become road warriors and work-from-home employees, wouldn't it be convenient to have shared work drives naturally converted to shared folders online, governed by the same security principles and the exact identity providers at work.

So why give up your Windows file server and adopt public online file sharing when you are outside of the company network? Wouldn't it be easier to add modern online file sharing and folder sharing capabilities to on-premise Windows file servers and modernize the file servers we are using every day?

The On-Premise File Sharing Benefits!

Triofox eliminates the common drawbacks of traditional file server access and cloud file sharing solutions and comes with the following benefits.

Guarantee Data Privacy

Businesses can address data privacy concerns by using Triofox 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 Triofox can facilitate that in any private cloud. Still, Triofox 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. Have an always-on mapped drive with endpoint protection and with streaming files over HTTPS for security and performance.

Simplify Management 

Centrally manage users, access controls, and storage for each tenant and each user. Easily keep track of where the data is, who has access and how it's being shared. All management operations are available from a web browser interface.

Centrally Manage Granular Permissions

Easily keep track of where the data is, who has access and how it’s being shared. For complete control and visibility, permissions can be managed from the file server that was their source, or natively with Triofox.

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 on-premise file server network 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. The local cache is encrypted, and a remote wipe feature is available.

On-Demand Synchronization

Mapped drives display directory structure but delay downloads until a file is used to reduce bandwidth usage and endpoint storage consumption. User accessed files are cached locally in an encrypted cache for local speed and protection.

Data Ownership

Triofox provides a web-based access layer on top of the Windows file server. Data resides within the Windows file server, and corporations maintain data ownership.

On-Premises Alternative to Dropbox and SharePoint

Triofox has the flexibility to provide an on-premises alternative to Dropbox and SharePoint using existing on-premise file servers and provide web-based remote and mobile access.
