Nortel and SecureLogix Team to Deliver Voice Security and Management Solutions to Worldwide Enterprise Market

SecureLogix Corporation and Nortel have formed a strategic relationship
to deliver first-of-kind voice security and management solutions to
enterprise customers worldwide.

Under the new sales and marketing agreement, Nortel and certified
Nortel resellers will market and sell the SecureLogix(R) ETM(R) System
and related voice security assessment

and monitoring services as part of Nortel's new Voice
Security Services offering. On May 6, 2008, Nortel and SecureLogix
announced that Spring Independent School District in Houston, Texas was
their most recent joint-customer win under the new services
relationship.

Nortel Voice Security Services combine patented technology from
SecureLogix with Nortel voice and security expertise to help enterprise
customers secure multi-vendor, multi-technology voice networks. These
services include assessment of costly voice service theft and misuse
across the enterprise, inefficient phone service configuration and
resource utilization, and underlying voice network vulnerabilities that
threaten the security of voice and data networks. Nortel resolves these
issues through 'best practices' consulting and implementation of the
SecureLogix ETM System.

The ETM System is a comprehensive voice network security and
management platform, enabling customers to protect critical voice and
data network resources from telephony-based attack and abuse, optimize
their telecom resources and expenditures, and simplify voice network
management. The PBX-independent ETM System unifies the security and
management of distributed, multi-vendor voice environments. The ETM
System is fully functional in today's TDM PBX environment, and supports
migration to Voice-Over-IP (VoIP)/Unified Communications.

"The role that voice networks play in ensuring corporate and data
security is emerging as a focus area for CIOs," said Rod Wallace,
general manager for Security Services and Solutions at Nortel.
"SecureLogix is recognized as one of the pioneers in the voice security
market, and this relationship helps Nortel to offer a unified,
360-degree means to view and mitigate threats across corporate voice
networks. Additionally, our customers can migrate to Unified
Communications with the full confidence that Nortel will optimize their
build-out with regard to cost and performance, while providing the
necessary protections to ensure the reliability, confidentiality, and
security of their business critical voice communications."

"SecureLogix is more than pleased with the customer interest and
revenue opportunities that the Nortel relationship is already
providing," added Joe O'Donnell, SecureLogix vice president of
Worldwide Business Development. "We have already inked a number of
deals through this relationship, and it's a privilege to work with a
global leader in Unified Communications. Together, we are truly
unifying enterprise telephony networks with services and solutions that
baseline, optimize and secure multi-vendor telephony environments."

"This relationship was spurred by our customers," added
SecureLogix President Lee Sutterfield. "Organizations are becoming more
aware of the threats to their telephony systems and the critical need
for dedicated voice network security and management solutions,
particularly as they consider migration to VoIP/Unified Communications.
Our expanding relationship with Nortel validates and heightens this
awareness. Without comprehensive voice security technologies to ensure
voice availability, quality of service, and confidentiality, broad
deployment of VoIP and Unified Communications will not be realized."

ETM(R) System

The state-of-the-art ETM System is the world's first real-time
media voice firewall, offering centralized visibility and control over
all voice network access and usage through automated security policy
enforcement. The system protects enterprise telecom and data networks
from telephony-borne threats such as denial-of-service, toll fraud,
service abuse, harassing calls, unmonitored Internet use over phone
lines, information theft and data leakage, phone-based identity theft
and 'vishing' attacks, modem line backdoors into the corporate LAN,
voice/fax spam, and other unauthorized phone traffic and usage.

The ETM System's voice usage and performance management
applications allow the enterprise to optimize telecom resources and
service use to significantly reduce phone bills and other voice network
operational costs through centralized, IP-PBX-independent call
accounting, resource utilization reporting, call recording, and
performance/QoS alerting and management capabilities for the
enterprise. The system's patented voice security and management
capabilities support both TDM and VoIP, enabling the world's first
unified voice security and management technology spanning legacy and
VoIP communications and infrastructure.
