Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"This is a hybrid solution."
"It is a very efficient and robust appliance."
"The DDoS protection features are valuable."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"I like the fact that the product provides a hybrid solution."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The most important aspect, in general, is that the price is suitable for most clients."
"The most valuable feature is being able to pull traffic patterns; to and from destinations. We're able to understand where our traffic is going, our top talkers from an AS set, as well as where our traffic's coming from."
"Honestly, it is one of those products that I would suggest to almost any network operator."
"Kentik excels in telemetry within data centers and works well in multi-vendor environments."
"This product is easily the best network monitor that I’ve ever seen or heard about."
"Collecting that data and having those metrics first-hand, in real-time, allows us to make an educated decision, versus an uneducated guess."
"Overall, I would give Kentik nine out of ten stars."
"I can say that I am so happy with this platform because it is very useful for us."
"Compared to PRTG, Kentik's real-time network monitoring features are definitely superior."
 

Cons

"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"It could use support in Spanish."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Juniper is known in our country, but it is not very popular."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
"The product could strive for more improvements to become closer to perfect."
"Kentik can be improved by enhancing the alerting system, especially the way templates work and the hierarchy of these alerts."
"My experience with pricing, setup costs, and licensing shows that the prices are quite high."
"I would like to see more granular user and security rights."
"Version 4 of the platform is good and going in the right direction."
"There is a large difference between BGP and normal nodes. I don't think this plays out to the best for the customer or Kentik."
"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."
"There is room for improvement around the usability of the API. It's a hugely complex task to call it and you need a lot of backing to be able to do it. I should say, as someone who's not in networking, maybe it's easier for people who are in networking, but for me that one part is not very user-friendly."
 

Pricing and Cost Advice

"The price of Corero is affordable."
"Its price is normal."
"The tool is cheaply priced."
"We have an annual contract with Kentik that we renew each year for a set number of licenses. We also have some burstable licenses which we can spin up and spin down, and those are paid as they are used."
