Are there specific software or tools that can help detect and prevent DDoS attacks on FiveM servers?

Yes, several tools are available. These include firewall software (like pfSense or iptables), intrusion detection systems (IDS) like Snort or Suricata, and DDoS mitigation services like Cloudflare, Akamai, and Imperva. Some server monitoring tools also offer basic DDoS detection capabilities. The choice depends on the server's technical capabilities and budget.
