DDoS Protection Service Selection Considerations

Key Metrics for Evaluating Protection Needs

1. Mitigation Capacity

The maximum attack traffic the service can absorb. Usually measured in Tbps.

2. Attack Type Coverage

Different services have varying protection capabilities for various attack types:

Attack TypeDescription
L3/L4 attacksUDP Flood, SYN Flood, etc.
L7 attacksHTTP Flood, Slowloris, etc.
Reflection amplificationDNS, NTP Amplification, etc.

3. Time to Mitigation

Time from detecting an attack to beginning defense. Shorter is better.

4. SLA Guarantee

Service availability guarantee, usually expressed as a percentage.

Evaluation Checklist for Choosing Protection Services

Ask yourself these questions before choosing:

  1. If our service is attacked for one hour, how much money do we lose?
  2. Where does most of our traffic come from geographically?
  3. Which cloud services do we already use (AWS, Azure, GCP)?
  4. How much technical staff do we have for maintenance?
  5. What's our budget range?
