Featured Reviews

Dns architect at a outsourcing company with 5,001-10,000 employees
Robust protection has secured global web assets and keeps critical applications available
F5 Silverline Managed Services can be improved in areas with complex onboarding processes and slow deployment settings. Tuning of policy requires significant technical expertise, and there is a lack of knowledge in the F5 world where one needs to go through a steep learning curve in understanding what and how the policy should be configured for effectively protecting an application. These processes need to be streamlined.Knowing the limitations of F5 Silverline Managed Services, F5 has come out with a new product called F5 distributed cloud WAF platform, which has a better API integrated with security modules. It also offers advanced auto discovery, swagger, and open API validation, which is much better than Silverline.

Automated threat intelligence and flow-based mitigation have improved our DDoS defense
A very useful feature in Arbor DDoS is its ability to send flow spec announcements to routers. For example, if it is clear that a Layer 3 or Layer 4 attack is occurring and the attack pattern is identified through source and destination IP addresses and ports, you can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS. This allows the TMS to focus on other tasks. This is a highly effective feature that can mitigate huge volumetric attacks; for example, we experienced a 32-gigabit attack, and all those 32 gigabits were dropped by our border routers, not by Arbor DDoS itself. The flow spec announcement was generated by Arbor DDoS, and as far as I know, the same technology is used by Radware, but it comes under a different feature and a different license. At the time, we were told that flow spec mitigation was an additional very expensive license to purchase from Radware, while Radware included everything in one package.
