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.

Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Quotes from Members

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

Pros

"This product is easily the best network monitor that I’ve ever seen or heard about."

"Overall, the ease of use and the fact that it meets client expectations are major positives."

"It offers a simple yet powerful feature of classifying applications, going beyond basic statistics."

"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."

"Kentik has positively impacted the organization by providing greater control over certain subjects and enabling monitoring of current traffic."

"I am able to do a lot of work on the visualization end to create different visualizations and different ways to get information out of it."

"Before using the solution, we had to do all these manual tasks, such as running all these queries manually, and building our tech cost-report used to be a two or two-and-a-half-week effort, and using Kentik, and the automation that it provides us, we've brought that down to a day or two, which is a massive time savings."

"Kentik excels in telemetry within data centers and works well in multi-vendor environments."

More Kentik pros

"There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies."

"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."

"Go take a look at it. It's a great product and has great capabilities."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

More Observer GigaStor pros

Cons

"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..."

"Sometimes it's difficult to order the dimensions correctly when trying to make Sankey flow diagrams."

"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."

"Kentik can be improved in terms of languages, and visually it could be improved a bit more as well."

"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."

"Version 4 of the platform is good and going in the right direction."

"It also detects anomalies proactively, but the same is not so true when it comes to real network problems, since they tend to just happen."

"The product could strive for more improvements to become closer to perfect."

More Kentik cons

"The Observer Console UI is consistent and stable, but could use some updating to be more modern."

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."

Pricing and Cost Advice

"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."

"It's quite expensive."

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."
