SOMERSET, New Jersey, November 11 /PRNewswire/ --

- Lumeta's IPsonar to give BT customers unprecedented ability to map Networks, identify vulnerabilities, and improve overall security

Lumeta, the leading provider of network assurance solutions for enterprises and government agencies, today announced they would bring the advanced network assurance capabilities of Lumeta's flagship product, IPsonar, to BT's customer base.

Under the agreement, BT will market and resell IPsonar, and will also make it a core part of its Secure Networking Quick Start Service -- a unique offering that combines BT's tools, knowledge, and experience to enable organizations to rapidly assess their network security, identify weaknesses, and then take cost-effective remedial and preventative measures.

We view IPsonar as playing a key role in any network security assessment, said Ray Stanton, BT's global head of business continuity, security, and governance. You cannot understand how secure or insecure your network is until you actually understand what devices and interconnections form your network. IPsonar is unique in its ability to discover and map the network -- known and unknown -- and then highlight potential areas of vulnerability.

BT is clearly at the forefront of helping organizations build and maintain truly secure networks, commented David Hickey, Lumeta's president and chief executive officer. Their Secure Networking Quick Start Service, and, more generally, their selection of Lumeta's IPsonar as their network assurance tool of choice, demonstrate BT's keen understanding of the comprehensive steps required to ensure network integrity, security, and availability.

As part of the agreement, consultants from BT and all of it's affiliate companies can now offer Lumeta's IPsonar to quickly and easily:

- Uncover gaps between policy and network defenses to support regulatory compliance and audit efforts; - Manage and measure security based on a complete and accurate understanding of the network; - Understand the relationship between risk and availability; - Mitigate the risk of major network change events such as network consolidation or transformation; and - Prioritize vulnerability assessment and remediation.
