We’ve added support for SSH firewalls on Hypernode! This new feature lets you restrict SSH access to specific IP addresses, adding an important layer of security to your server.
Important: Unlike our other allowlists (for FTP, WAF, and database), SSH is open to the entire internet by default. As soon as you add an SSH allowlist entry, SSH access will be restricted to only the IPs you’ve added – all others will be blocked.
To allow access for your current IP via SSH, run:
hypernode-systemctl whitelist add --description "My IP" ssh 1.2.3.4 You can manage allowlist entries via the CLI or the Hypernode control panel.
📚 Learn more about how the SSH firewall works, and how it differs from other firewall types in our documentation:

Make sure to add your own correct IP addresses before applying SSH allowlist rules — otherwise, you may lock yourself out.
