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.
DerrickAkankwasa - PeerSpot reviewer
Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.
