Cyren Ltd. (NASDAQ: CYRN, TASE: CYRN), formerly known as Commtouch, was a cloud-based, B2B cybersecurity technology company. Founded in 1991, Cyren specialized in providing security as a service (SecaaS) and threat intelligence services, including email security, web security, anti-malware, and advanced threat protection. In February 2023, Cyren filed for bankruptcy protection and subsequently announced the sale of its assets and the winding down of its operations. This page provides historical information about the company, its products, and its role in the cybersecurity industry prior to its cessation of operations.
The McLean headquarters served as the global corporate hub, overseeing strategic direction, finance, sales, marketing, and administrative functions prior to the company's operational wind-down.
The McLean office was situated in a modern business park, typical for tech companies in the Northern Virginia tech corridor. The Herzliya office was known for its strong engineering and threat research capabilities.
Historically, Cyren fostered a culture of innovation in cybersecurity, with a global team environment focused on threat research and the development of cloud-based security solutions. (Note: Operations ceased in 2023).
The McLean, VA location provided Cyren with proximity to the U.S. market, government agencies, and a rich tech talent pool. The Herzliya office was crucial for R&D, tapping into Israel's renowned cybersecurity expertise.
Prior to ceasing operations in 2023, Cyren maintained a global presence to support its cloud-based security services. This included a network of strategically located data centers worldwide that processed billions of daily internet transactions for threat detection and analysis. Key functions supported globally included: real-time threat intelligence gathering, cloud security service delivery (email, web, DNS security), 24/7 security operations, international sales and marketing, customer support, and distributed research and development teams.
