BDM at a comms service provider with 11-50 employees
Based on stability, I would give Kentik a nine.
Network Engineer III at Fortanix
I can say it is so great for us because if we configure it with Flowspec, the orchestration that we use, which is Kentik, makes the decision and automatically forwards the traffic to another position that we have in our network, or outgoing that we use.
Telecomm Analyst at a tech company with 11-50 employees
It is a very stable product.
Team Lead Network Engineer at Artco Group d.o.o Sarajevo

More work is required to integrate AI for troubleshooting, simplifying root cause analysis, and providing suggested solutions for network issues.
BDM at a comms service provider with 11-50 employees
It needed to be a bit easier for new users and have slightly more customized reports.
Network Analyst at a comms service provider with 501-1,000 employees
Currently, the way I'm configuring it uses reactive alerts, which means alerts are triggered when an issue occurs. I would prefer more proactive alerts in the future.
Epicor Engineer at Sunway Group
I would like to see an option to decrypt the traffic with Arbor DDoS, as some clients are interested in this, particularly for application layer attacks on port 443.
Network Engineer at A1 Bulgaria
Enhancing the handshakes between Arbor DDoS and third-party solutions is essential for obtaining better and real-time data that supports any organization’s support team effectively.
System Engineer at TIGER LOGIC
I would like to see a roadmap for one or two years, and it is tough to predict what will happen in that timeframe without a clearer description.
CTO at UkrNet

Valuable Features

Kentik offers comprehensive network monitoring, real-time analytics, security insights, customizable dashboards, and automation for efficient network management.
NETSCOUT Arbor offers scalable DDoS protection with user-friendly features, AI-enhanced detection, and cloud integration, ideal for effective threat mitigation.
The best features that Kentik offers are the ability to identify traffic end-to-end and to know which transit is used, if it goes through any other transit, to see the entire flow, from the subscriber to the content provider and vice versa.
Network Engineer at a media company with 51-200 employees
This allows for better understanding of whether there is a critical ongoing case related to incoming traffic, such as a DDoS event, which is crucial for a service provider dealing with numerous customers.
Network Engineer at a comms service provider with 51-200 employees
Kentik has positively impacted our organization because when something happens, we use Kentik to analyze the problem and it brings us a faster solution to the problem, and the troubleshooting is clearer.
Telecomm Analyst at a tech company with 11-50 employees
That is an attack over 10 gigabit per second, and if an attack enters the telecommunication network, that will be a disaster for their customer, their services, and so on.
Team Lead Network Engineer at Artco Group d.o.o Sarajevo
We have many updates for the library of different attacks, and they have artificial intelligence that automatically learns the process during different attacks.
CTO at UkrNet
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.

Traffic insights have reduced transit costs and support secure, direct connections with providers
The best features that Kentik offers are the ability to identify traffic end-to-end and to know which transit is used, if it goes through any other transit, to see the entire flow, from the subscriber to the content provider and vice versa, from the content provider to the subscriber.I can also determine whether it is symmetric or asymmetric traffic, and if it goes through any provider that has some kind of bottleneck. That is very important. Regarding the security part, which is also possible to handle through Kentik, you can configure it in a way that makes the network more secure and reduces the amount of dirty traffic or attacks received. Kentik has had a high positive impact on my organization. Besides the cost reduction, it has been possible to perform troubleshooting more effectively, and also regarding DDoS-related attacks. In addition to cost reduction, we had a more reliable connection. Since the moment we identified that it was possible to have a direct connection with content providers like CDN77, Cloudflare, and Akamai, we established a direct connection there through a PNI with these content providers, making the network less dependent on an IP transit provider.

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.
