Cyren Internet Security

Cyren GlobalView™: World’s largest threat intelligence cloud

Cyren has built the industry’s largest global security intelligence cloud, powered by threat data from over 500,000 network collection points in over 180 countries. Operated across 19 global data centers, Cyren’s security cloud powers our SaaS web security and email security services, and provides some of the world’s leading technology and security vendors—including Google, Microsoft, IBM, Check Point and Fortinet—with the fastest and most accurate threat data in the industry.

The most security data

Every day, the Cyren cloud processes over 25 billion transactions generated by over one billion users across multiple threat vectors to assemble an unmatched view of cyber threats as they emerge. Cyren detects thousands of new, never-beforeseen IP addresses, phishing sites, and malicious URLs on a daily basis, providing the deepest and most instantaneous data in the industry on threats as they happen.

Big data analytics

Cyren’s data collection footprint and patented detection capabilities combine with extensive expertise in Big Data, advanced heuristics, and machine learning to build actionable global security intelligence on a near-real-time basis. Our cloud cyber security platform: automatically investigates and correlates IP addresses, domains, hosts, and files associated with suspicious behavior; builds risk scores; and is capable of instantaneous reclassification.

The best cyber intelligence

This real-time, actionable cyber intelligence powers Cyren’s cloudbased enterprise web and e-mail security services and is used by over 200 technology and security vendors. Our security cloud enables protection from malicious messages, hosts and websites with almost no false positives. Intelligence gained from any transaction within the Cyren cyber security platform instantly updates protection for all users.
