How to choose a DDoS protection provider

For an e-commerce operation, a denial-of-service attack can interrupt sales and support. The impact depends on the service affected, the duration and the team's ability to respond.

In a distributed denial-of-service (DDoS) attack, traffic or requests from multiple sources try to degrade or interrupt a service. Choosing a provider requires more than a headline bandwidth number: understand how the service is deployed, what it covers and how its team responds during an incident.

Start with service impact

An organization should know which services are essential, how users reach them and which failures it can tolerate. A protection provider may filter malicious traffic upstream or at the application edge, but the placement and capacity of those controls affect the result.

DDoS can overwhelm bandwidth, connection state or application resources. Some application attacks consume relatively little bandwidth, so ask how each kind is detected and handled.

Consider more than IoT botnets

Attackers can use botnets of compromised devices, including poorly secured connected equipment, to generate distributed traffic. DDoS attacks can also use amplification and other methods; not every attack relies on an IoT botnet. Organizations should assess their exposure and prepare a response. CISA DDoS mitigation guidance.

Plan an operational response

Botnets continue to change, and attackers can use DDoS for disruption or extortion. An organization should consider both upstream filtering and an incident response plan, including contacts and escalation procedures. CISA DDoS mitigation guidance.

Attack timing and motives are uncertain. Organizations should prioritize protection according to the business impact of downtime and the exposure of their public services.

What to look out for in a DDoS protection provider

Use these three areas to compare providers against your own architecture and response needs:

1. Network capacity: Ask about available bandwidth, packets per second, geographic reach and upstream capacity, and how the provider validates its advertised limits under attack.

2. Deployment model: Compare cloud, on-premises and hybrid options against your routing, latency, failover and operational requirements. None is automatically the right choice for every network.

3. Coverage and response: Confirm which network, transport and application attacks the service addresses, how false positives are handled, and who operates mitigation and escalation. Test the response plan before an incident. .
