Effectively protects clients from automated threats and ensures global security
I cannot say much about areas of improvement for Cloudflare Web Application Firewall because I haven't gone through deep understanding of it, as I am still learning. However, they need to improve their support because getting a response for basic requests took around 48 hours, which is too long. If I took 48 hours to answer a request at my company, it would be a tough time to see or address the issue, and it would be frustrating.
