owner or administrator of a high-security network, you are
acutely aware of the security risks and threats involved in data
transfer. That is why security requirements forbid your
high-security network to be physically connected to any external
network. This often means that data from an external source
needs to be transferred manually on a portable data medium, such
as a USB stick, CD or DVD. What is more, this time-consuming
transfer is not done in real-time, and more importantly, creates
a leading European supplier of complex, high-impact security
solutions, we too realize a breach of data security could have
wide-ranging negative effects involving national security,
financial fraud, industrial espionage (commercial interests) or
This is where our Fox DataDiode really comes into its own.
Totally secure, its hardware-driven, one-way data connection is
tailored to connect your high-security networks. Rest assured,
such risks and threats are a thing of the past.
But there is more. This elegant security solution is real-time,
fast and easy to use, while offering the same high—if not even
higher—standard of security you demand.
The Fox DataDiode, a perfect, hundred-percent-secure solution,
transfers data—online, in real-time and continuously—between
two networks of varying security levels without compromising the
security of the receiving network. This is largely due to a key
component: the Fort Fox Hardware Data Diode.
The Fort Fox Hardware Data Diode, a unique hardware-based
communication device, is central to the solution. It deploys a
gigabit optical data link to transfer data in only one, single
direction (hence the term ‘diode’). In this way, a
low-security network is connected to a high-security network, or
to a network with the same level of security, but without any
risk of data loss or intrusion to the high-security network.
A Fort Fox Data Diode configuration comes with two
commercial-of-the-shelf servers, connected to the transmitting
and receiving networks to provide additional user and
Features and benefits
The Fox DataDiode offers security and data integrity, enhanced
through the use of event logging, and error detection and
correction. It also boasts an easy transfer procedure and
user-friendly interface. Furthermore, users of the receiving
network are able to receive e-mail from outside their network,
print locally or access frequently used websites or databases,
all without exposing their high-security network to outside
risks or threats.
In a nutshell, the Fox DataDiode offers the following features
• Unique hardware-based, one-way data link whose security has
been approved by the Netherlands National Communications
Security Agency (NL-NCSA), and is accredited up to and including
(NATO) SECRET level
• Easy to use web interface for users, administrators and
• Automated/scheduled procedures for web and database
• Error detection and correction for data integrity
• Event logging and SNMP traps on both sides of the data
transfer for detecting (and responding to) unlawful or
• Time synchonisation for the high-security network
• Continuous online data link: no need for time-consuming,
risky and expensive manual transportation of confidential data
using a portable data-storage medium, such as a USB-stick, CD or
The Fox DataDiode also allows users of the high-security network
• Receive (not send) e-mail from the low-security network
• Locally access frequently used websites, databases and FTP
• Locally print jobs from the low-security network
To place things in perspective, it is useful to review the
current alternative: the manual air-gap data transfer procedure.
In addition to the effort, time and cost involved, this form of
data transfer also introduces security risks through possible
loss of portable storage media, or their incorrect disposal.
Moreover, this type of transfer is neither continuous, nor is it
conducted online nor in real-time.
Users and applications
The Fort Fox Hardware Data Diode’s proven technology is
currently deployed in several countries and within multiple
Developed primarily for security-conscious government
authorities, such as defense organizations, intelligence
agencies and the police, the Fox DataDiode is equally suited for
deployment by commercial organizations. These could be financial
institutions or highly competitive R&D environments.
Applications range typically from transmitting tax returns to a
tax authority’s back-office network; and transferring
intercepted telecom data to a police or intelligence network for
analysis; to transferring data between NATO’s secret network
and a member government’s own high-security network.
