Deep eBPF insights have strengthened cluster security and simplified mesh troubleshooting

The documentation is good, but they could improve in that area. Someone who is new to networking might feel daunted going through all those detailed materials. They could have high-level documentation first, and if anyone wants to deep dive into any areas, they can read more on that. They could segregate the information in the documentation. Documentation is one of the major areas for improvement. Apart from that, the product is quite good. I love it, and everything is good. The AI features are okay. They are still researching and improving in that area, but the guardrails are good, and everything works as expected for now. However, I think it would be good if they improve in that area. I would not say it is 100% correct. Sometimes it does hallucinate, but overall it is good.

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

"Using Isovalent's Cilium, I have seen that it will be really helpful for the design and implementation teams who are actually building this cluster and providing it to the end users."

"We have noticed reduced incidents as a specific outcome that shows how things improved."

"Isovalent has positively impacted my organization by ensuring that after moving to Isovalent products, we trust the tools we chose for the community, particularly the powerful tools such as Cilium."

"Isovalent is a quite good company, and I love their products."

"Isovalent is easy to use and very fast to set up all the things, and if I had used other tools instead of Isovalent, it would take maybe one or two days; however, using Isovalent will reduce your time and it completes within one to two hours."

"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 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..."

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

"Enables us to go back in time to capture an issue and analyze it for a solution, and this after the fact analysis is key to overcoming the bump in the night issues."

"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."

"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."

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

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

Cons

"Sometimes I feel the costing is a bit high, on the higher side."

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

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

"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."

"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."

"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."

"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."

"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
