Black Box, a provider of voice communications and data infrastructure, has launched Veri-NAC network access control appliance family designed to prevent network security breaches.

The company said that Veri-NAC only lets authorised computers and devices onto a defined network. It also checks to make sure each connected machine complies with specified standards, including up to date operating system, patch management, and hardened configurations.

Additionally, if a device is deemed to contain vulnerabilities, it can be locked out of the network except for the resources the user needs to bring the computer into compliance.

According to the company the Veri-NAC offering doesn’t require the installation of software agents on connected machines. It also works with existing network and legacy infrastructure.

The company also claims that the up-front cost for Veri-NAC is lower compared to other products and its architecture reduces the cost of network access control.

Josh Whitney, product manager of Black Box, said: “We’re very excited about our new Veri-NAC offering because its simplified agentless architecture means it’s both highly secure and much more cost-effective compared to traditional NAC solutions.

“This is the NAC solution for organisations that haven’t been able to implement solid network security because of the high costs and complicated configurations previously associated with NAC technologies.”
