API Technologies Receives U.S. Patent for Technology Used for Intelligence Collaboration across Multiple Computer Networks

ORLANDO, FL — August 24, 2011 — API Technologies Corp. (NASDAQ:ATNY) ("API" or the "Company"), a provider of electronic systems, subsystems, RF, and secure systems for defense, aerospace, and commercial applications, announced today that it has been awarded a U.S. patent for its system and method for traversing metadata across multiple network domains at various layers of the protocol stack. This patented technology, awarded to the Company’s Cryptek™ product line, part of the Secure Systems and Information Assurance (SSIA) Division, is a core component in its Netgard™ Encryption Suite, enabling coalition information sharing (across a single network) while providing multi-domain security for Service-Oriented Architecture (SOA) infrastructure components like databases and applications servers. The Netgard Encryption Suite will be on display at Booth #636 at LandWarNet, August 23-25 in Tampa, FL.

"This new technology simplifies the task of coordinating servers, data, and user activity to ensure that the user is able to access only appropriate information given his or her security clearance," said Rick Mahar, VP & General Manager, SSIA Division, API Technologies. "Moreover, since the technology uses a single core infrastructure, set-up and tear-down time is minimal, and there is no need to buy new hardware when someone is added to the team."

The availability of the Netgard Encryption Suite was previously announced at the Information Assurance Exposition as an alternative to Type-1 encryption for secure environments. It uses NSA-approved Suite B encryption algorithms to provide security while releasing the user from the logistical burden of traditional Type-1 solutions. The product is expected to begin shipping by the end of 2011. Additional information can be found at www.apitech.com/products/netgard-encryption-suite.
