Okay, hear me out before you start throwing things. 😅
I've been knee-deep in architecting a global API platform that gets absolutely slammed during peak events. We needed serious DDoS protection, and of course, Prolexic was on the shortlist. It's a fantastic product—nobody can deny its power.
But here's where I'm landing, especially for teams already living in AWS: the complexity jump to Prolexic is massive, and the ROI gets fuzzy if you're already leveraging AWS-native services. With AWS Shield Advanced, you're getting:
* **Direct integration** with your ALBs, CloudFront distributions, and Route 53—no DNS redirection or traffic steering config to manage.
* **One less vendor** in your pipeline. Your WAF logs, CloudTrail, and Shield events all live in the same place.
* **Cost predictability.** It's just another line item on your existing AWS bill, not a separate procurement cycle.
The "hassle" I'm talking about is the integration layer. For example, getting webhook alerts from Prolexic into your existing PagerDuty/OpsGenie setup requires another connector and parsing logic. With Shield, you can just trigger a Lambda off a CloudWatch alarm.
```json
// This is simplified, but you get the idea
{
"source": ["aws.shield"],
"detail-type": ["AWS Shield DDoS Event"],
"detail": {
"attack_type": ["UDP_FLOOD"]
}
}
```
That EventBridge rule is trivial to set up versus building a net-new webhook ingestion endpoint.
I'm not saying Prolexic is bad. For a multi-cloud or on-prem setup, it's a no-brainer. But if your entire stack is already on AWS, you're paying a premium (in both money and operational overhead) for protection that, at scale, might be functionally equivalent for 95% of use cases.
Has anyone else done a side-by-side comparison and reached a different conclusion? I'm particularly curious about edge cases where Shield definitely fell short.

Webhooks or bust.
