Remote Access to File Shares Without a VPN

"CentreStack Provides The Best Alternative for VPN File Sharing!"

Remote Access over the Cloud

The Challenge

Virtual Private Networks (VPNs) have been the traditional answer for secure remote access to network file shares on legacy 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.

The Solution

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 without VPN


The following data flow illustrates the basic architecture and data flow for this solution. You can click the picture for the remote access architecture diagram.

Step 1

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

Step 2

Credentials are passed securely over HTTPS to the CentreStack server

Step 3

The external firewall only needs to open port 443

Step 4

The CentreStack Server passes the credentials to the AD domain controller

Step 5

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

Security Benefits

With CentreStack, businesses get all the security of traditional file servers without VPN headaches. In fact, security is enhanced since file access is restricted to assigned users through protocols like LDAP and CIFS/SMB which doesn't expose the whole network as a VPN would.

Data Privacy

Data is managed in place on existing file shares. Authenticated users access internal file shares remotely based on existing permissions.

Access Controls

Use existing AD users and NTFS folder permissions to automatically present a user's assigned file shares in their mapped drive.

Minimal Exposure

Signing into a traditional VPN grants access to the entire internal network. CentreStack only exposes the files users need.

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 end point device ready to help with file and folder access.


Mapped drives delay downloads until files are opened and cached locally for fast future access, significantly reducing bandwidth and storage consumption. Users get local performance when working remotely.


Line of business and legacy applications are unaffected as internal users can continue to work without making any changes using the internal mapped drives they have grown accustomed to.


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.
