It's a good product. We can manage SSL certificates within the CDN, and they're auto-renewed and auto-purchased outside the CDN, which is a cool feature. So, I would rate this product a nine out of ten. I recommend this product. If anyone is looking for a next-gen WAF and next-gen CDN, it's the best product I've come across. It utilizes AI to enhance features, especially while tagging anomalies and traffic anomalies, but I'm not 100% sure. I've heard they're using some AI to identify bot traffic and malicious traffic.
I advise others to make a purchase decision depending on the budget. If they have a budget, they should go with Cloudflare. I have used Signal Sciences, Azure, and AWS. They need to work more efficiently to protect web applications. I rate Signal Sciences a six out of ten. It has good granularity features, but maintenance and agent approaches could be more convenient.
My organization used Signal Sciences for the internal application or in case any customer tried to integrate their application with our application. We found that the solution was secure for such applications. I advise users to choose Signal Sciences. However, they should evaluate the solution based on their requirement and ask for the feature request if something is missing. Overall, I rate Signal Sciences an eight out of ten.
