Version 4.1.2

Cyren Cloud Security integrates all of Cyren’s SaaS security offerings on a unified platform, composed of the Web Security service, Email Security service, and the DNS Security service, along with integrated advanced threat protection and sandboxing capabilities.

Cyren Web Security

Cyren Web Security provides a quick-to-deploy, easy-to-manage SaaS secure web gateway that protects your users with inline protection from advanced malware, ransomware and phishing, no matter where they are or what device they are using.  Advanced URL filtering, dynamic threat scoring, anti-malware inspection and cloud sandboxing provide comprehensive web protection.

Cyren Email Security

Cyren Email Security is a cloud-delivered service designed to protect organizations from spam, malware and phishing and ensure uninterrupted email communications, and offers fully integrated, inline cloud sandboxing.  Cyren Email Security examines email at many levels for the key characteristics of spam, phishing, and virus outbreaks, including applying Cyren-patented detection techniques to email distribution patterns globally.  

Cyren DNS Security 

Cyren DNS Security is an automated, location-based service providing web filtering to manage user web access and protect from malicious sites. It requires no user authentication and is intended to quickly and easily protect all users at your locations, such as your employees at headquarters, visitors in your remote offices, customers at your retail stores, or students on a campus.
