In my recent project, I'm evaluating how to combine a content distribution solution with DDoS protection and edge-level firewall policies. I need to balance performance and security without inflating costs, using techniques like aggressive caching, TLS termination, request limiting, and real-time traffic analysis. I'm also curious about how they handle integration with authentication and monitoring systems. What criteria do you consider most critical when choosing a provider for these services? Any best practices for configuring security rules and monitoring incidents without impacting user experience? I’d appreciate your experiences and suggestions.
How to focus on DDoS protection and CDN for a startup?

A common oversight is managing certificates when TLS termination happens at the CDN. What strategy do you follow to maintain automatic renewal without the process interfering with the startup’s security policy? In resource-constrained environments, ACME automation can save time, but it also means giving the CDN access to the private key; have you considered using short-lived keys or delegating signing to an internal CA to minimize exposure?
Another point of confusion is the visibility of firewall logs at the edge. When you delegate inspection to the CDN layer, how do you integrate that data with your SIEM or monitoring tools? In some cases, the lack of correlation between CDN logs and application logs can make it harder to identify sophisticated attack patterns, especially when clients use variable source IPs.
Finally, I wonder how you handle rate limiting in a microservices scenario. If the CDN applies global throttling, how do you ensure critical services aren’t degraded by an overly aggressive rule? Do you use differentiated rate-limiting policies by path or client type, or do you prefer a token-based solution validated by the backend itself?
