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.

Quotes from Members

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

Pros

"The DDoS protection features are valuable."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"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."
"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."
"It offers a simple yet powerful feature of classifying applications, going beyond basic statistics."
"Monitoring operational efficiency is easy."
"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."
"Overall, the ease of use and the fact that it meets client expectations are major positives."
"Kentik excels in telemetry within data centers and works well in multi-vendor environments."
"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."
 

Cons

"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"Lacks international presence."
"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."
"The product must provide more Layer 7 capabilities."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"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."
"I consider the pricing model as an area for improvement."
"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."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
"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..."
"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."
 

Pricing and Cost Advice

"Its price is normal."
"The price of Corero is affordable."
"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."
