Waterfall Security Unveils New Unidirectional Gateway Version with Unparalleled Industrial Cyber Security Capabilities

February 22, 2012

TEL AVIV, Israel, February 22, 2012 /PRNewswire/ –

Waterfall Security Solutions Ltd., the leading provider of Unidirectional Security
Gateways(TM) announced today the start of shipments of a new generation of its
Unidirectional Gateway products. This release sets a new standard for comprehensive,
unidirectional protection of industrial networks, with innovations in both unidirectional
hardware and security software capabilities.

The new release incorporates insights from Waterfall’s existing installed base in
energy, oil & gas, water and other critical infrastructure segments, from Critical
Infrastructure Protection-related regulatory authorities, and from lessons learned from
recent advanced cyber attacks.

Waterfall’s new WF-400 hardware addresses the top two needs of the unidirectional
security industry: industrial grade, mission critical stability and robustness, and
protection against advanced cyber threats. The WF-400 introduces support for unparalleled
throughput, while maintaining minimal power consumption. The throughput increase provides
customers with an evolutionary path for supporting their current and future needs and
allows industrial customers to take advantage of very high conventional data volumes,
including applications such as advanced remote monitoring and assistance applications. Low
power consumption is important to many industrial and mission critical sites, in meeting
the challenges of their power restricted environments. The new hardware comes with dual
network ports built in, providing native support for high-availability, redundant
configurations which are able to tolerate any single point of hardware failure with no
loss of data.

A unique feature of the new WF-400 hardware is integrated support for hardware
protocol whitelisting. The hardware can be configured to allow and/or completely disallow
specific communications protocols, including the routable Internet Protocol. This
capability is important in the North American power industry, where the latest NERC-CIP
guidance in the form of CAN-0024, was recently released. CAN-0024 makes it clear that
unidirectional communications equipment which prohibits routable protocols, such as the
Internet Protocol, qualify for certain provisions in the NERC-CIP standards which are not
available to equipment which forwards Internet Protocol messages. The hardware protocol
whitelisting also provides a new layer of protection against the ability of even the most
advanced threats to “phone home” and send any information at all back to Internet-based
command and control centers.

In addition, new software versions of Watefall’s patented unidirectional server
replication solutions provide enhanced support for Linux, and 32 and 64bit Windows
operating systems and special support for hardened operating system versions.

“Our innovative Unidirectional Gateway technology suite is already deployed and
operational in leading industrial and mission critical sites around the world,” said Lior
Frenkel, Co-Founder and CEO of Waterfall Security Solutions, “The development of the suite
reflects Waterfall’s close relations with critical infrastructure customers, other
industry leaders and regulatory authorities, which has helped us in defining and designing
a comprehensive platform to meet the most advanced cyber security challenges.”
