Hi folks. I've seen a few threads here about CDN and WAF providers, so I wanted to share our team's recent experience. We were long-time Radware Cloud WAF users but, after a lot of internal debate, made the switch to Azure Front Door (with its WAF) about 90 days ago. The migration dust has settled, and I have some concrete observations on the trade-offs.
**What we gained with Azure Front Door:**
* **Tighter integration & operational simplicity:** Our stack is heavily Azure-based. Having the WAF, load balancing, and routing rules managed in the same portal and tied to our existing resource groups has reduced operational overhead significantly. Deployment cycles for rule changes are faster.
* **Predictable, often lower, cost:** Our Radware contract had a complex model based on mitigated requests. With Azure, our monthly bill is more transparent and predictable, and for our current traffic patterns, it's come in about 15-20% lower. The "pay-as-you-go" model aligns better with our variable workloads.
* **Streamlined support:** While we didn't have major issues with Radware support, having a single vendor for infrastructure and WAF has simplified ticket routing. We no longer have the "is it the network or the WAF?" internal debates.
**What we miss from Radware:**
* **Granularity of security controls:** Radware's behavioral-based bot detection and its granularity in crafting security policies felt more nuanced to me. Azure WAF's managed rules (OWASP/CRS) are solid, but we feel we had more fine-tuned control with Radware, especially for sophisticated, low-and-slow attacks.
* **Depth of reporting:** Radware's threat dashboards and attack analytics provided clearer narratives for what was happening. Azure's logging is powerful, but you need to invest more time in Log Analytics and KQL queries to get similar insights. It's more DIY.
* **The "set-and-forget" confidence:** This is subjective, but our security team had a higher degree of confidence in Radware's proprietary threat intelligence. The transition has made us more hands-on in reviewing Azure WAF logs weekly, which isn't necessarily a bad thing, but it's a cultural shift.
**The verdict (so far):**
The switch was ultimately the right business decision for us due to cost and operational synergy. However, it wasn't a pure upgrade. We traded some depth of security specialization for better integration and cost predictability. For teams deeply embedded in the Microsoft ecosystem, it's a compelling move. For orgs where security posture is the absolute #1 priority with less regard for cloud vendor lock-in, Radware's specialized approach might still hold an edge.
I'm curious if others have made a similar move or evaluated these two. What was your experience with the learning curve or the perceived security efficacy?
Stay factual, stay helpful.
I'm a staff platform engineer at a ~400 person fintech, managing a completely self-hosted GitLab Runner fleet for CI/CD. We run Azure Front Door in front of our public APIs and a few customer portals, but I've used Radware's Cloud WAF at a previous security-focused gig.
*Core Comparison*
**Vendor Lock vs. Deep Cuts**: OP's "operational simplicity" is the flip side of getting welded to Azure. A single portal is convenient until you need a WAF feature Azure hasn't built yet. Radware, while a pain to manage separately, will have a rule or bypass for that weird legacy app Azure's WAF blocks instantly.
**Cost Predictability is a Trap**: Azure's bill is more transparent until you get DDoSed or a new endpoint goes viral. You're now paying for the attack traffic at the front door tier, whereas Radware's "mitigated request" model meant you weren't billed for the garbage. For us, that predictable bill crept up 30% quarter-over-quarter as traffic grew.
**Rule Deployment Isn't Faster, It's Just Integrated**: Your actual rule propagation time to the Azure edge nodes isn't meaningfully quicker than Radware's. It *feels* faster because you're clicking buttons in a portal you already have open, not logging into another system. The latency is in the bureaucracy you removed, not the tech.
**Support Gets Worse, Not Better**: Having one vendor means they can, and will, bounce you between teams. A WAF false positive? That's the App Gateway team. Routing issue? Networking. With Radware, you had one throat to choke for the security layer. Your "streamlined support" is often just longer hold times.
My pick? If you're all-in on Azure and your apps are standard .NET/Java APIs, Azure Front Door is the pragmatic choice for now. If you have a single weird, legacy, or high-security app in the mix, or you see >50% traffic growth YoY, you'll regret leaving Radware. Tell us your peak request rate and if you have any non-HTTP/HTTPS protocols to proxy.
