To enhance your droplet's security, consider implementing additional measures beyond fail2ban. First, ensure your DigitalOcean droplet is up-to-date with the latest security patches. Review your `iptables` configuration to restrict incoming traffic to necessary ports only. You may also want to configure rate limiting on your exposed services to slow down potential attackers. Consider setting up a Web Application Firewall (WAF) to protect your website and apps from common web attacks.
