Cyren Cloud Security Documentation

Cyren Email Security provides security best practices to eliminate the need for in-house well trained security specialists.
Cyren Cloud Security includes 3 default best practice policies for email protection:

  • Security policy: This default policy is a preset configuration aimed to detect and protect from known threats and new emerging threats. Depending on the email protection license, the relevant threat detection engines are configured to protect you against standard threats in the standard package or both standard and advanced threats in the advanced packages. Threat types are wide and all known threat types, both identified and emerging threats (Viruses, Cryptos, Phishing elements, impostor elements, etc). Cyren`s threat detection engines are built to identify threats by various means like volumes, behavior, elements, etc.
  • Spam protection: Includes all threat protection means in the Security policy plus wide protection against all types of spam, unsolicited, Greymail and are solicited by chance.
  • Productivity: Includes Security and Spam filtering with the addition of all bulk mails including news and legitimate marketing feeds.

The Email Protection>Incoming> Rules tab shows a list of all protection rules, order of priority, and status. The incoming protection exposes policy settings for standard as well as advanced threats, spam & news and empty messages handling and provides 3 default policy sets – Security, Spam and Productivity, and enables you to create one or more protection rules that are applied in a hierarchical order to create an overall, organization-wide protection plan (essentially a corporate policy).
