What are the security implications of exposing Nextcloud AIO directly to the internet, even with Cloudflare?

While Cloudflare provides DDoS protection and SSL/TLS encryption, it doesn't eliminate all security risks. Ensure your Nextcloud AIO Docker container is regularly updated with security patches. Implement strong passwords and two-factor authentication. Monitor Nextcloud logs for suspicious activity. Consider using a web application firewall (WAF) in addition to Cloudflare.
