Case Studies


Secure Your Transfers, Your Network and Your Data

Secure file transfer only solves a piece of your data security and compliance requirements.  There are other considerations that, if overlooked, can result in costly compliance violations or data security breaches.

Securing the files on your server

When files are stored on your server, there is still a need to assure that they are protected from unauthorized access.  Cornerstone’s Real-time PGP encrypts the files on your servers with the highest industry-standard encryption.  This process avoids interim steps that the unencrypted data to the disk.  Cornerstone encrypts that data on the fly so that it is never exposed, and does not require additional steps to sanitize deleted data.

Securing Access to your Network

Preventing unauthorized access to your network, without increasing complexity for you users and IT department, is easily accomplished with Cornerstone.  Using a combination of perimeter security and two-factor authentication, risks of network breach are greatly reduced.

Perimeter Security with DMZedge.  To keep unauthorized users out of your network, the optional DMZedge server, used in with CornerstoneMFT, enables you to close inbound ports on your firewall, opening a dynamic outbound connection to service user requests.

Two-factor Authentication e-tokens.  Text passwords can be easily broken, and users frequently write them down or share them.  CornerstoneMFT, used in conjunction with WebDrive, adds a second layer of authentication security – one that is not easily compromised.

Securing File Transfers

When files are uploaded or downloaded from your server, you need the assurance that they are safe from unauthorized access.  This is especially important if you store financial or healthcare data.  Cornerstone secures your files transfers using your choice of secure protocols.  You can use SFTP or run FTP or WebDAV through an SSL encrypted connection.

Cornerstone can require all connections to the server to be secure, refusing any unsecure connections.

DMZedge Server


The DMZedge Server enables you to close inbound ports on your firewall, reducing the risk of network intrusion and enabling the highest level of security for both data storage and transfers. When combined with the Cornerstone MFT Server, the DMZedge Server uses a two-way connection originating from the Secure MFT that is inside of the firewall on your corporate LAN. The DMZedge works as a communication proxy, replacing unsecure inbound connections from the Internet to your internal network.

How DMZedge Works

The DMZedge Server works as a proxy between users on the Internet and your secure corporate LAN. DMZedge Server resides in the Demilitarized Zone (DMZ) – outside of your corporate firewall. The Cornerstone MFT Server that resides on your network initiates a session with the DMZedge through a secure outbound connection. All incoming client requests and data are forwarded to the back-end server through a connection that has already been established between the MFT Server and the DMZedge Server. The MFT servers reside securely behind your corporate firewall, although ease of access for your end users is as simple as if the servers were in your DMZ. Data storage and authentication take place on the back-end server, and no inbound ports are opened through your firewall.
