  • Rich GEO access rules. Set Your Own Rules on what country can submit forms, post comments, login or register. Using REST API or XML-RPC.

FAQ about WP Cerber Security Pro

If my license is expired, the PRO version of the plugin stops working?

No. The plugin will continue to protect your website with the same level of protection as the free version does, but support and updates are not available. Read more: How subscriptions work.

I have multiple websites, can I use one license for all of them?

WP Cerber Security Pro licenses are valid on a per-install basis, meaning you need one for every WordPress instance you run. If you have three separate WordPress website, you will need three licenses in total — one for each site. However, if you have ten sites in a WordPress multisite instance, you need just one license for all ten sites.

I need several licenses, is a volume/bulk discount available?

Yep! The bulk discount will automatically be applied to your order depending on the number of license keys you buy.

Is there a developer license for unlimited installations?

For the time being, we have no such license mainly because we offer a cloud-based solution and each client website consumes server resources which are not cheap. But we will work out some developers program soon. Feel free to contact us if you have an idea about it.

How can I move a license key to another website?

You need to remove the key from a website and send a request to our support team to unlink the key from the site. You will be asked for the Site ID. Once the key will be unlinked, you can use it on another website.

Does cloud-based mean all web traffic is routed through the Cerber Tech servers?

No, it doesn’t. The PRO version of the plugin filters out malicious traffic locally on your web server. The plugin communicates with a closest Cerber Tech cloud server to receive updates for security rules, malicious IP addresses, country information and then uses this data to protect your website.

How do I know that Cerber Tech cloud is reliable?

We’ve developed an innovative fault-tolerant architecture and monitor our servers 24/7/365. Check out an independent, third-party status page: https://stats.uptimerobot.com/D9Z5QF0JN
