Riverhead Networks was founded by Yehuda Afek, Anat Bremler-Barr, Dan Touitou, and Yuval Rachmilevitz in 2000 in Tel Aviv, Israel. Initial funding was provided by Cisco and Gemini Israel Funds. On March 22, 2004 Cisco Systems paid $39 million to acquire full control of the company. Following the acquisition by Cisco the company’s development center was relocated and merged with the existing Cisco Israel Development Center in Netanya 
Riverhead Networks provided solutions for Distributed Denial of Service (DDoS) by using a series of complex algorithms to alert and prevent them. Riverhead Networks's technology would allow company's IT systems to continue operating, even in the midst of an unauthorized or DDoS malicious assault.
