Yes. For 2–5 servers, we apply the same configuration across all. For larger fleets, we recommend Ansible-based automation (separate service).
No. We set up your SSH key authentication first, verify your access works, and only then disable password login. You always retain full root access via sudo.
fail2ban monitors failed login attempts and automatically blocks IPs that exceed the threshold. Without it, servers face thousands of automated brute-force attempts daily.
Basic firewall awareness (ensuring SSH port remains accessible) is included. Full UFW/iptables rules for all services are available as an add-on (+$50).
Optional but recommended. Changing the default SSH port reduces automated brute-force noise by 90%+. We configure the new port and document it in your admin guide.
