Guardent uses open source, services for security

Guardent is betting that the combination of open-source security software, managed services and a hardware device will translate into tighter security for customers with its new Security Defense Appliance, announced Wednesday.

The Security Defense Appliance, or SDA, combines a trio of open-source security applications with Guardent's event correlation, reporting, monitoring and response, and managed services, the company said in a statement.

The SDA uses the open-source software IP Tables to provide firewall capabilities, Snort for intrusion detection and Nessus for vulnerability assessment, the company said. Those programs are then married with Guardent's services, which are managed by Guardent from its Secure Network Operations Center, the company said. The SDA is installed at the customer's premises, but is managed remotely, with monitoring and threat response coordinated round the clock by Guardent.

By combining the open-source software with Guardent's correlation and monitoring services, the company aims to notify customers of network vulnerabilities, attacks and other problems, while also cutting down on the false positives that such services often generate, Guardent said.

The service also offers a Web-based report system, through which customers can view a real-time status report of security events generated by SDA.

The SDA service will be available in January and will cost US$1,500 a month.
