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 product allows the users to adjust the thresholds."
"The solution is very user-friendly and very easy to use."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"It is a user-friendly product in terms of monitoring and updating policies."
"I find the interface easy to use."
"We've been completely satisfied with the product."
"The most valuable feature is the cloud DDoS scrubbing capability."
"It allows me to see all the traffic on my network."
"We haven't seen anything else that comes even close to Kentik's real-time visibility across our network infrastructure, and we've demo'ed everything under the sun."
"Good NetFlow visualization and analysis tools are valuable to anybody who needs to understand the traffic that flows in and out the network."
"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."
"Monitoring operational efficiency is easy."
"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, the ease of use and the fact that it meets client expectations are major positives."
 

Cons

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The solution can be a little more user-friendly and it can be more affordable."
"I would like to see analytics, big data."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"The initial setup is complex. It is always complex."
"The product’s pricing needs improvement."
"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."
"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."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
"I've checked out the V4 version of the interface and it's still a little bit clunky for me to use."
"The product could strive for more improvements to become closer to perfect."
"The only downside to Kentik, something that I don't like, is that it's great that it shows you where these anomalies lie, but it's not actionable. Kentik is valuable, don't get me wrong, but if it had an actionable piece to it..."
"Perhaps a better explanation would be to see how tagging is captured and a method of comparing my tagged interfaces on Kentik’s side."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"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."
 

Pricing and Cost Advice

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