Overview
Radware is a global provider of cybersecurity, application delivery, traffic management, and application performance technologies. Founded in 1997, the company developed around the needs of data centers and internet-facing applications, combining network traffic management with protection against attacks and service disruption. Its portfolio spans physical appliances, virtualized software, and cloud-based services, allowing organizations to deploy controls across traditional infrastructure, private and public clouds, and software-defined environments. The company was co-founded by Roy Zisapel, who has served as Radware’s president and chief executive officer since its inception and has also held a director role. Radware completed an initial public offering in 1999 and became a NASDAQ-listed company. It is associated with the Rad Group of technology companies, a group founded by the Zisapel family. Radware’s global headquarters are in Israel, while its corporate headquarters are in Mahwah, New Jersey. It maintains offices and commercial operations across Europe, Africa, and the Asia-Pacific region and sells through distributors and resellers worldwide. Radware’s business is organized around several connected technology areas. Its application and network security products address distributed denial-of-service attacks, web application threats, malicious traffic, network intrusion, and data-exfiltration risks. Its application delivery portfolio supports load balancing, application availability, traffic steering, and performance optimization. Cloud offerings extend these capabilities into managed and subscription-based services, including cloud web application firewalls, cloud DDoS protection, workload protection, web acceleration, malware protection, and bot management. Management and monitoring tools provide visibility, policy control, orchestration, and performance oversight for enterprise and service-provider environments. The company expanded its capabilities through a series of acquisitions. It acquired V-Secure Technologies in 2005 to strengthen behavioral network intrusion prevention, Covelight Systems in 2007 for web application auditing and monitoring, and Nortel’s application delivery business in 2009. In 2013 it acquired Strangeloop Networks, adding web performance optimization capabilities. Radware acquired Seculert in 2017 to broaden its cloud-based protection against enterprise breaches and data exfiltration, followed by ShieldSquare in 2019 to add bot-management technology. These transactions helped Radware move beyond appliance-centered application delivery toward a broader security and cloud-services portfolio. Radware serves organizations in financial services, insurance, electronic commerce, manufacturing, retail, government, healthcare, education, transportation, communications, hosting, and telecommunications. Its customer base includes enterprises, cloud and hosting providers, carriers, and other organizations whose operations depend on the availability and security of internet-facing applications. The company’s route to market includes direct enterprise relationships together with distributors, resellers, and service-provider channels. The brand is positioned around maintaining the availability, performance, and security of digital applications. Rather than focusing solely on endpoint security or traditional network firewalls, Radware emphasizes the intersection of application delivery and cyber defense. Its public recognition has included industry awards and analyst placement for web application firewall and DDoS-prevention capabilities, including recognition in India and an IDC MarketScape assessment. Radware remains an active international technology company with a portfolio spanning on-premises infrastructure, software-defined deployments, and cloud-delivered protection.
History
Radware was founded in April 1997 by Roy Zisapel and other members of Israel’s technology sector. From the beginning, the company focused on technologies that could improve the availability and performance of networked applications while also addressing the security risks associated with internet connectivity. Roy Zisapel became the company’s president and chief executive officer and has remained in those roles since its founding. The company reached the public markets in 1999 through an initial public offering on NASDAQ. Its corporate structure and ownership have been associated with the Rad Group, a group of Israeli technology companies established by the Zisapel family. Radware developed an international presence, operating from Israel while establishing corporate headquarters in Mahwah, New Jersey, and offices and commercial coverage in Europe, Africa, and the Asia-Pacific region. Its products were distributed globally through a combination of direct sales, distributors, and resellers. During the 2000s, Radware built its reputation in application delivery, traffic management, and network security. The company expanded through acquisitions that added complementary technology. In 2005, it acquired V-Secure Technologies, bringing behavioral-based network intrusion-prevention capabilities. In 2007, it acquired Covelight Systems, whose technology addressed web application auditing and monitoring. In 2009, Radware acquired Nortel’s application delivery business, reinforcing its presence in application delivery and load-balancing markets. Radware continued to broaden its application-focused portfolio during the 2010s. The 2013 acquisition of Strangeloop Networks added web performance optimization for enterprise and electronic-commerce applications. Radware also developed products and services addressing DDoS attacks, web application security, application monitoring, and data-center traffic management. Its portfolio increasingly covered both physical appliances and software-defined or virtualized deployments. In 2017, Radware acquired Seculert, a SaaS-based provider focused on protection against enterprise network breaches and data exfiltration. This transaction supported the company’s expansion into cloud-oriented security services. In January 2019, Radware acquired ShieldSquare, a provider of bot-management technology. The deal extended Radware’s cloud security portfolio into the detection and mitigation of automated web traffic, including malicious or abusive bots. Radware’s modern portfolio spans cloud security, application and network security, application delivery, and management and monitoring. Cloud services include web application firewall, DDoS protection, workload protection, web acceleration, malware protection, and bot-management offerings. Security products include DefensePro, AppWall, and DefenseFlow, while application delivery technologies include Alteon, FastView, AppXML, and LinkProof NG. Management products include Cyber Controller, APSolute Vision, an MSSP Portal, application performance monitoring, and vDirect. The company sells to a broad range of industries, including financial services, insurance, electronic commerce, manufacturing, retail, government, healthcare, education, transportation, telecommunications, hosting, and cloud services. Its customer and partner ecosystem includes enterprises, carriers, service providers, and data-center operators. Radware has also received industry recognition for its web application firewall, anti-DDoS, cloud, and cybersecurity products. Its strategic development reflects the convergence of application availability, performance optimization, and cybersecurity as organizations increasingly rely on internet-facing digital services.
