SANTA CLARA, CA–( EMWNews – April 2, 2008) – nexTier Networks (www.nextiernetworks.com),

a Silicon Valley-based startup emerging from several years of development

in “stealth mode,” today announced that it has completed the development of

a breakthrough semantic analysis engine capable of handling the accuracy,

scale and performance required for the protection of information in today’s

enterprises. nextTier’s patent-pending algorithms are optimized to

identify, at network speed, the origin and classification of information in

use within the entire enterprise so that proper policies can be applied in

real-time, insuring that information handling is in line with corporate

policies. Immune to information tampering, the technology will initially be

used to address the shortcomings of existing Data Leak Protection (DLP)

solutions and will be productized to complement existing deployments as

well as provide complete solutions.

nexTier is believed to be the first to have developed technology that

protects information based on cutting edge semantic analysis techniques.

nexTier’s technology can discover with extreme accuracy where a specific

piece of information came from, for example from which document, database,

email, and so forth, even if that information was modified or retyped in a

different context. The technology has proven to be greatly resistant to

evasion techniques, and it enables the transparent enforcement of security

policies that control where information can go and with whom it can be

shared — even across multiple enterprises. The algorithms underlying the

core technology are also language-independent and can, for example, process

at the same time and with equal accuracy English, French, Arabic, and Asian

content.

“For too long IT professionals have been promised true security for their

most sensitive information, only to be disappointed by technologies that

are fairly easily circumvented,” said nexTier Networks’ Founder and CTO

Tarique Mustafa. “We have combined complex semantic intelligence with

unique security algorithms to produce the first disruptive data leak

protection technology to enter the security space in a long time. Our

approach uses patent-pending algorithms to solve real-world information

security problems that have long proved intractable because of the cost,

scale, speed, and/or accuracy limitations of other solutions.”

To achieve such a high level of accuracy at the scale of the modern

enterprise, nexTier had to innovate on multiple fronts. The Company’s

Security-Semantic CORelation and indEXxing (S2 COREX™) algorithms can

discover, classify, and index information in real-time within a security

context using breakthrough methods that overcome the accuracy, scale and

speed limitations of traditional Latent Semantic Indexing (LSI) and other

similar algorithms. In addition, to specifically protect content

identified as security critical, nexTier developed new algorithms to

extract, or “sequence,” just enough information — the equivalent of a

human’s DNA in concept but using less than 1000 Bytes — to always

accurately identify any information that came from those documents. This

unique “Semantic DNA Sequence™” can be used to identify where information

came from even if such information was extensively modified or repurposed

by someone either accidentally or maliciously. As such, the technology

exhibits a remarkable immunity to content modification.

“Today’s data security products are hamstrung by their dependency on

traditional non-semantic techniques that are inherently susceptible to

evasion and which carry high administrative costs due to their large

storage capacity needs,” said Bernard Harguindeguy, veteran executive of

the information security industry at such companies as Greenborder

(acquired by Google), Sygate (acquired by Symantec), and WorldTalk

(acquired by Tumbleweed). “nexTier’s unique Semantic-DNA Sequencing™

technology and S2 COREX™ semantically-aware security algorithms can be used

transparently and automatically deep inside the enterprise network to very

effectively track and protect information.”

“By adding real-time semantic intelligence to data security, nexTier is

changing the rules for what enterprise customers should expect,” said Matt

Ocko, a seasoned Silicon Valley Venture Capitalist and member of nexTier

Networks’ Board of Directors. “The combination of accuracy, automation, and

performance on a very large scale will establish nexTier as a force to be

reckoned with in the fast-growing security market. The fundamental nature

of nexTier’s underlying Semantic-DNA™ technology not only enables better

information security for businesses, but its core innovation will also

impact many related technology areas over the next few years.”

nexTier Networks will begin shipping their revolutionary new level of

information security technology and product in early Q3 of 2008.

About nexTier Networks

Headquartered in Santa Clara, CA, nexTier Networks created a whole new way

to secure business information by firewalling data at what the company

calls the “semantic layer” — the network communications layer at which the

semantic meaning in data is communicated. Following years of research and

development, nexTier delivers breakthrough semantically-aware security

algorithms to identify, classify and protect information in real time

across very large volumes of content with unprecedented accuracy. The

company was founded by Silicon Valley security veteran Tarique Mustafa and

is backed by a team, board and advisors that include many leading

authorities from companies like Symantec, McAfee, VeriSign, Cisco, Juniper,

GreenBorder, Sygate and Securify.
