About Captus Networks

Captus Networks, established in 2000, was a cybersecurity firm specializing in intrusion prevention systems. The company's primary focus was on developing security solutions to protect the network integrity of its clients, which included enterprises, internet service providers (ISPs), government agencies, and universities. Operating from its headquarters in California, Captus Networks designed and marketed security devices aimed at safeguarding networks from denial-of-service and distributed denial-of-service attacks.

Read full description

The core of its business was providing comprehensive, policy-based security that preemptively addressed a wide range of unwanted network activities. The company's flagship product line, the IPS 4000 Series, was an automated system that combined 'Day Zero' protection with traffic management features. This system was designed not just to prevent known threats but also to clean the network of attacks and unwanted traffic that signature-based systems could not detect, thereby preserving bandwidth for mission-critical applications. This approach provided clients with a detailed overview of network behavior and helped to ensure predictable network availability.

Throughout its operation, Captus Networks secured significant funding to fuel its growth and product development. In May 2001, it raised $16.1 million in a second funding round co-led by St. Paul Venture Capital and GMS Capital Partners, bringing its total raised capital to $19.6 million. Later, in October 2003, the company announced a fourth round of financing worth $12.4 million, led by GMG Capital Partners, to expand its product line and increase market awareness. On January 30, 2007, Captus Networks was acquired by DeepNines Technologies, marking the conclusion of its journey as a privately held entity.
