New Extension for Plesk. Antivirus Protection to enhance your server security. Why choose Flex Antivirus?
Two installation methods available: via a CMD command on the server or manually from the Plesk panel.
Check that your server meets the requirements before installing
We recommend Windows Server 2025. The extension is compatible with Plesk Obsidian and later versions. It is not compatible with Linux servers.
Choose the installation method you prefer
Connect to the server via Remote Desktop (RDP) and open CMD as Administrator. Run the following command:
plesk bin extension.exe --install-url "https://www.flexservices.app/ext/plesk-flex-firewall-manager.zip"
Plesk will download and install the extension automatically. The process takes a few seconds.
Once completed, the extension will appear available in the Plesk extensions panel.
If you prefer to install the extension manually from the Plesk panel, follow these steps:
ZIP file and click Install. If you don't see the "Upload Extension" option, follow these steps to enable permissions in the panel.ini file
Get and activate your license from the extension panel
Once the extension is installed, access it from the Plesk panel in the welcome wizard to complete the setup.
Promotion: If you have a promo code or license, you'll enter it in the wizard.
Enable the services you want to monitor and protect
After activating the license, configure which services you want to protect. You can enable or disable each module independently:
Monitor incorrect access attempts on email or FTP services.
Block bots and brute force attacks on web panels and WordPress.
Protect remote access to the server against intrusion attempts.
Monitor and block unauthorized access to databases.
We recommend enabling at least the SMTP and Web modules in the initial configuration for immediate basic protection.
Boost protection by combining the local firewall with Cloudflare
If you use Cloudflare on any of your domains, Firewall Manager can integrate to block IPs directly at the network layer, even before traffic reaches your server.
Each Plesk Client can store their token individually to manage their domains, CDN, Cache, DNS, etc ...
You can easily get the Token from the Cloudflare section itself. With this integration, every IP blocked by the local firewall will also be automatically added to the Cloudflare rules, providing a double layer of protection.
