MDI’s ONE Unified Technology™ First Security Integration Platform to Receive DIACAP Certification to Operate on Federal and DoD Networks

New Certification Empowers MDI’s Current and Future Government Customers to Easily Comply with White House Directives (HSPD 12) on Identity Management

SAN ANTONIO, Texas –February 25, 2008 – MDI, Inc. (NASDAQ: MDII) announced today that MDI Security Systems’ award-winning ONE Unified Technology Platform has received the new DIACAP (Department of Defense Information Assurance Certification and Accreditation Process) certification from an independent third-party laboratory for approval to operate on secure government networks. With several thousand government operating locations, military bases and federal agency headquarters as customers over the past twenty years, the MDI system has remained the U.S. Government standard for unified access control, video surveillance and alarm management.

DIACAP is the required security process with which all Government information systems will receive certification and accreditation (C&A) to manage information assurance capabilities and information technology networks. Currently, without the DIACAP product certification, operation on Department of Defense information systems is not allowed without the ultimate designated approval authority accepting an unknown network-centric risk from an un-accredited product.

DIACAP certification will allow MDI Security Systems to further generate new business from DoD clients and continue to support its current Defense Department customers with Unified Security and Identity Management solutions across the world, which include:
• United States Army (includes the ICIDS Integrated Commercial Intrusion Detection System)
• United States Navy (includes all of US Navy Europe)
• United States Air Force (numerous sites across the United States)
• United States Marines (currently includes every Marine base worldwide)

MDI’s security command and control platform has been selected by a multitude of federal, state and local governments because they cost-effectively deliver the most flexible, reliable and advanced unified security solution available. The same holds true with commercial organizations across the nation who regularly do business with the Federal Government and DoD.

MDI was the first industry physical access control system to unify the DoD’s Common Access Card (CAC) program over ten years ago, which promotes the use of a single smart card that functions as a common credential for computer access, facility access and a growing range of additional uses. MDI provides this same unified solution for its Federal Civilian Agency clients, to achieve total compliance with recent federal identity management mandates such as:
• FIPS 201 (Federal Information Processing Standards)
• TWIC (Transportation Worker Identification Credential) and
• FRAC (First Responder Authentication Credential).
