ADRIANA SALDARRIAGA TOBON - PeerSpot reviewer
Client experience and cybersecurity have improved with an easy setup
The solution is valuable for client experience, especially in the financial sector. The most important feature is cybersecurity. The pricing is good, but the functionality is the most important aspect for clients. The solution is easy to deploy and requires only one person to set up, making it easy and quick. Overall, the ease of use and the fact that it meets client expectations are major positives.
KL
A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

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

Pros

"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."
"One of the valuable features is the intuitive nature of building out reports, and then triggering actions based on specific metrics from those reports. It has a really good UI and the ability to surface data through the reporting functions is pretty good. That's helped a lot in the security space."
"The most important feature is cybersecurity."
"In terms of the solution’s real-time visibility across our network infrastructure, I have not been able to find any other monitoring or netflow visualization tool that gives me the kind of information I get from Kentik. If I need to take a deep-dive into something that I see, it's really easy for me to do that. Whereas with most other things, I have to use five or six other tools to get that kind of data, with Kentik, I have it all in one place."
"We're pretty happy with the API functionality. It's web, and it's very simple to set up queries. It has served us well and you don't need to be an expert on the API or the product to set these things up."
"We're also using Kentik to ingest metrics. It's a useful feature, and its response time, whenever we're pulling back the data, is higher than our on-prem solution."
"It offers a simple yet powerful feature of classifying applications, going beyond basic statistics."
"Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"One of the valuable features is the packet decoding."
 

Cons

"I believe they're already working on this, but I would love for them to create better integrations from network flow data to application performance — tracing — so that we could overlay that data more readily. With more companies going hybrid, flow logs and flow data, whether it be VPC or on-prem, matched with application performance and trace data, is pretty important."
"I've checked out the V4 version of the interface and it's still a little bit clunky for me to use. I still go back to the old interface. That's definitely one that they still need to work on. It doesn't seem like everything that you get in the V3, the older interface, is there. For instance, I was trying to add a user or do the administrative tasks in V4, and I couldn't figure out where I was supposed to do that."
"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."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
"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."
"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."
"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."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
 

Pricing and Cost Advice

"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."
"Licensing is quite expensive."
