Featured Reviews

Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.
Lilian Blaitt - PeerSpot reviewer
Efficiently identifies and addresses vulnerabilities while providing robust protection
It is a secure tool. It is user-friendly and easy to work with. It is possible to easily find vulnerabilities with the WAF. I understand that the return is good since I haven't had any significant attacks. The vulnerabilities I found were easy to close. I think the return is good. It is a good tool.
