Server firewall is not first line of defense.
If a flood saturates upstream capacity, the application never gets chance to respond. Protection needs to happen before hostile traffic reaches origin links.
Check coverage before buying
- Layer 3 and Layer 4 protection for exposed IP services.
- Routing model for VPS, dedicated servers and routed prefixes.
- Support process during attack windows.
- Logs or evidence needed to review an incident.
Do not ignore application risk
Network mitigation does not replace rate limits, WAF rules, secure auth, patching, caching or good backup practice.
