NetScreen purchased OneSecure for $40.3m (£27m) in NetScreen stock and the assumption of OneSecure's outstanding options, NetScreen said.
NetScreen offers a broad selection of hardware appliances and software that run firewalls and virtual private networks (VPNs). The company is, increasingly, coming to challenge market leaders Check Point Software Technologies and Cisco Systems in these areas.
Along with a range of security features, the acquisition of OneSecure also brings NetScreen a security appliance. OneSecure sells the Intrusion Detection and Prevention (IDP) system, which offers users a distributed system with which they can work to protect their networks.
The IDP system includes intrusion detection and prevention using attack signatures, anomaly detection for both traffic and protocols, denial of service protection and spoofing protection in its suite of features.
The deal is expected to close, pending standard approvals, within 30 days, NetScreen said. The company will offer the IDP system after the deal closes.
In the first half of 2003, NetScreen will integrate some of the IDP system's features into its existing product line, as well as work to enhance the IDP and merge the companies management software.
In the longer term, NetScreen intends to develop the chips and other hardware required to integrate the OneSecure technology into a single security gateway.
