What CAI Networks does

CAI Networks, Inc. is a privately held Southern California-based designer and manufacturer of network appliances for IP load balancing, traffic management, and security, founded in 1987 as a computing consulting company and pivoting to networking in 2001 after acquiring Red Hill Networks' product line. The company's core product is WebMux, a solid-state, diskless hardware load balancer operating at OSI layers 2, 3, 4, 5, and 7, supplemented by proprietary features including MAP (Multiple Address/Port), BAM (Burst Activity Management), integrated SSL acceleration, DDoS protection, and FIPS 140-2-compliant cryptography. The portfolio also includes DnsMux for global/wide-area load balancing, FireSafe firewall, CAI-RSA SSL acceleration cards, WebSpray stress-test software, and a separate WebControl programmable logic controller line. Business model is primarily indirect two-tier channel sales through authorized distributors (AVANU in USA/EU, Assured Network Solutions in Australia/Asia Pacific) and resellers worldwide, with list prices from $3,999 to $12,900 per appliance, three-year bundled warranty and technical support, and additional revenue from maintenance contracts, professional services, and factory pre-configuration for enterprise and government customers. Named end customers include the U.S. Navy, U.S. Department of Commerce, Microsoft, CNN.com, General Dynamics, Sony, Siemens, Sprint, Verizon, and the 2010 Asia Games Organising Committee. In August 2012, CAI Networks divested the WebMux and DnsMux product lines to AVANU; the company continues to operate with remaining product lines and retained engineering IP.

Products and services

• WebMux Load Balancer Network appliance for IP load balancing and traffic management across OSI layers 2, 3, 4, 5, and 7 in a local area across a pool of web servers. Manages traffic and persistence, automatically allocates traffic across multiple servers for performance, bypasses failed servers for availability, and includes security features to prevent attacks that could compromise web site availability. Operates as a solid-state hardware appliance with proprietary MAP and BAM features, SSL termination/acceleration, DDoS protection, and dual-stack IPv4/IPv6 load balancing validated against USGv6 and JITC.
• DnsMux Global Load Balancer Network appliance for balancing IP traffic in a wide area across multiple web hosting sites. Manages performance by automatically allocating traffic across multiple sites (each of which may have multiple servers), bypasses any site that should fail, and optimizes performance by routing each user to the geographically closest site. Supports IPv6 and FIPS 140-2 compliance.
• CAI-RSA SSL Acceleration Cards Add-in hardware SSL co-processor cards (CAI-RSA3500 and CAI-RSA7000) providing enhanced SSL performance for WebMux and FireSafe installations processing significant SSL traffic. Based on an advanced SSL co-processor chip and automatically supporting the OpenSSL FIPS Object Module.
• WebSpray Windows-based software that stress-tests web servers to determine their capacity by simulating up to 1,000 clients from a single IP address and supporting multiple IP addresses. Tests all pages, runs multiple times, and reports broken links and capacity results.
• FireSafe Network Firewall Network appliance firewall creating a barrier between an organization and the outside world, with rules-based access control (time-based, address-based, authenticated), URL filtering, access logging, and intrusion notifications via alarms, pages, phone calls and email. Uses solid-state design with no hard disk.
• WebControl PLC Programmable Logic Controller product line with WebControl 8 and WebControl 32 variants, firmware versions for PLC programming and IO expansion, browser-based GUI configuration, and ThingSpeak.com reporting integration. Designed for industrial control and remote monitoring/automation applications.
