Enabling server side scanning is very simple. Just follow these steps:
Once you log in to your Sucuri account, enter your website’s name and click on "Add Site."
Once you add the site, you will see a Monitoring Overview.
Even though your site has been added to the dashboard, Server Side Scanning still needs to be manually enabled. The server side scan is much more thorough than the external scan.
To enable it, you need to enter your FTP credentials into our system. You can start by clicking on the site and then Settings > Server Side Scanner.
There are two ways of doing this: automatically or manually.
Enter your FTP host, username, password and directory into the boxes below.
If you run into issues or if you don\’t know your FTP credentials, you can try manual verification.
Once the file is on the server, just click on "Verify File and Enable."
If everything was done properly, you should get a confirmation message.
When the file has been verified, the scan will be queued on the monitor server and should complete in the next few hours.
To run Server Side Scanner, your hosting provider must support PHP, TLS 1.2, and your site must be publicly accessible.
If you are still not sure what do, please feel free to open a support ticket with the Sucuri team.
