Narus, provider of intelligence software to monitor network traffic and boost cyber security, has raised $8.7 million in a recapitalization round from American Capital, Mayfield Fund, NeoCarta Ventures, Panorama Capital and Walden International. The Sunnyvale, Calif., company has previously raised $90 million over five rounds of funding, reports VentureWire.

Narus says it will use the new financing to add to its sales headcount to keep up with steadily growing demand. With more enterprises relying on networking services and more cyber security issues highlighted in the media, companies like Narus have seen business boom.
