What is most valuable?
Overall, the solution is good.
The machine learning aspect of the solution has been great.
The deployment is not that complicated.
ELK is open-source, and it will give you the framework you need to build everything from scratch.
What needs improvement?
The SIEM modules in Logstash, need more improvement. In the future, the modules could be more advanced as right now there are only very basic modules.
We are facing an issue with the engineers. In the region, there are not many available. Only a few people might be available in our particular region, which is a problem.
There isn't really a very good user experience. You need a lot of training. There is an interface with limited options. You need to work with the coding and you need to work with the scripts. It's not simple. If you want to configure something, for example, you need to be a proper programmer.
It would ideal if they had a dashboard. Right now, the only way to see what you need to see is to go through all of the logs.
For how long have I used the solution?
I've used the solution for one and a half years.
What do I think about the stability of the solution?
The stability of the solution is good. However, it depends on the configurations. If the solution is configured properly from the beginning, it will be stable. However, if the solution is not configured from beginning properly, it will not be. This is due to the fact that ELK Elasticsearch gives you the framework only, and the customizations depend on the guys who will be coming to configure everything for the company.
What do I think about the scalability of the solution?
The scalability is good, however, there is a certain level of skill that is needed. Due to the lack of trained engineers in the area, this could be a challenge.
How are customer service and support?
We've reached out to technical support in the past. We found that sometimes communication with them was difficult as there was a lack of understanding. This means that it takes a longer time to reach a resolution. However, in the end, when we have had issues, we were able to resolve them, even if it was a bit delayed.
Which solution did I use previously and why did I switch?
I've also worked with LogRhythm and there is no comparison. LogRhythm is the best solution for me. The use cases are better and are readily available. In contrast, with ELK, we need to deploy a lot of things. We need to program people and we need skills and training. We need a lot of things. Even the LogRhythm training is easier than ELK. With ELK, you need to build the customization, rules, everything, from scratch. WithLogRhythm, you just have to enable features.
If a company wants some more specific detailed use cases, then ELK would be better than LogRhythm, however, for a generic use case, LogRhythm is better.
How was the initial setup?
The initial setup is pretty simple and straightforward. It's not overly complex.
That said, it does require trained specialists, and there just aren't that many in our area.
Overall, I would rate the setup process at a two out of five.
The configuration must be done correctly, and that depends on who is configuring it. If the person configuring it, for example, only has an administrator background, he will configure the administrator stuff. If he has a security background, he will configure for security.
What other advice do I have?
We are a partner.
I'd advise others considering the solution that ELK is a good solution, however, it requires skills and capability. You need to be properly trained with it to get the most out of it.
I would rate the solution at a five out of ten.
