Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

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

"The most valuable feature is the cloud DDoS scrubbing capability."
"The product allows the users to adjust the thresholds."
"The solution is very user-friendly and very easy to use."
"We have researched them all, and it's a good solution all around."
"We've been completely satisfied with the product."
"The protection resources and the support are valuable features of the solution."
"Packet inspection has been effective for mitigating DDoS attacks."
"We use it to protect our users and their data."
"I can say that I am so happy with this platform because it is very useful for us."
"Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools."
"Good NetFlow visualization and analysis tools are valuable to anybody who needs to understand the traffic that flows in and out the network."
"The biggest thing Kentik has given us is the amount of visibility we have into our own network now and knowing what's going on at a given time."
"The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there."
"Monitoring operational efficiency is easy."
"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 terms of overall vendor partnership, I'd give Kentik a nine out of 10; they're right up there as one of my best partners to work with, amongst all the contracts that I own, and they're very customer-centric, always available, with nothing too small or too big that I can't ask them to help with, and they seem to be willing and able to jump in no matter what."
 

Cons

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The initial setup is complex. It is always complex."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"We had faced some issues during an outage and were not able to get the desired results from Kentik tools. It took time to resolve these issues, which is why I give them eight points."
"We asked for a way, regarding the potential networks that exist, to hook Kentik up with external tools like peering DBs to correlate things together and see what we can do... This is all in the [next] beta now."
"I would like to see them explore the area of cost analysis."
"I've checked out the V4 version of the interface and it's still a little bit clunky for me to use."
"Sometimes it's difficult to order the dimensions correctly when trying to make Sankey flow diagrams."
"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."
"Kentik can be improved by enhancing the alerting system, especially the way templates work and the hierarchy of these alerts."
"They're moving more in a direction where they are saying, "Hey, here's information that you may be interested in or may a need," before the question has to explicitly be asked. Continuing to move in that direction would be a good thing."
 

Pricing and Cost Advice

"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
"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."
