Got this from my usual license supplier, which they got from Draytek:-
DrayTek’s Content Security Management functionality incorporates multiple features (APP Enforcement, URL Content Filtering, Web Content Filters, DNS Filtering). A sub-component of this is the categorisation component used by Web Content Filtering which uses the Cyren Web Filtering service for categorisation information.
DrayTek are aware of recent news regarding the operation of Cyren, which may affect the Cyren WCF products (Cyren and Cyren Zero Day) that DrayTek currently work with, Without the Cyren service, many aspects of the DrayTek Content Security Management functionality are unaffected.
However, the category-based Web Content filtering feature relies on a categorisation reply from Cyren's category server. If no reply is received then the category of the URL can not be checked by the router. As of today (24th Feb 2023) the category service from Cyren is still functioning correctly. However, given recent news, there is a possibility of an outage in the future.
DrayTek are developing an alternative solution to the Cyren categorisation service. Once confirmed, existing users who have activated a WCF licence with DrayTek will receive a firmware update to switch to the new service. The activation of the WCF service with DrayTek and any related functionality is unaffected as it is run by DrayTek using DrayTek’s MyVigor servers. We are currently working on beta firmware and expect it to be ready in the coming weeks of April. After the firmware upgrade is released, you will be able to switch to using the new service. If there is any further news then DrayTek will notify you of any further information.
