It is not possible to purchase and install ServerShield by CloudFlare anymore, what happened?
Cloudflare ServerShield extension in Plesk is not available for installation or license purchasing anymore since 28th of February 2020. Those customers who have the extension already installed and licensed will be able to use it.
Why it has been removed from the catalog?
CloudFlare who is an extension vendor is not maintaining it anymore.
Can I still use CloudFlare and Plesk?
Sure! CloudFlare as service can always be used with Plesk- it works also without the Plesk based integration. Extension was just making this process easier for multiple websites.
Do you have any alternatives?
At this moment there is no a replacement in Plesk for this component yet, however we are looking into both: a new integration with CloudFlare as well as alternative options currently.
