Manages network threats and supports application control with ease
The best advantage of F5 Silverline Managed Services is that it is easy to use. The admin guide they provide is easy to understand and allows for implementation within a few days. The traffic manager and the monitoring tool are valuable as well. The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals. It offers effective reports and monitoring capabilities.

Behavioral analytics and AI automation enhance security and performance
It provides protection for network applications and infrastructure level, and the best part is the behavioral-based detection that Radware provides us, along with real-time signature creation. We also have some applications where we have botnets running, and it provides protection against them. Web DDoS targets the application layer, which is layer seven of the OSI model. For that, we focus on the Web DDoS technique for bot-based attacks because we have many applications where bots are running. We also face many random URL attacks every day, and it protects against malicious or suspicious random URL attacks. It ensures both security and performance. It achieves this by learning behavior patterns and providing protection without blocking normal traffic. These are some of the features I am particularly satisfied with in this product.

I highly recommend Cloudflare. We switched from Akamai Prolexic to Cloudflare and couldn't be happier. We also got the worlds fastest DNS and speeded up our site load times with the 200+ edge locations near to our customers.

You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperva, I can recommend it (try it with a trial, you'll be able to have your own opinion).
