I have used different solutions in my previous company.

We also make use of Wazuh.

I've used Rapid7 a long time ago in a previous organization. This solution is much more basic and does not have as many features. 

We did use a different solution. We decided to switch to this product as it fit our needs. 

I have experience with Elastic Security, Rapid7, and IBM.

I have not used any other products that are the same. I only use Micro Focus Ops Bridge and SiteScope, which are traditional monitoring tools, so I can't categorize them. They are slow yet they can handle big networks. 

We currently use AlienVault for some clients and Elastic Security for others. We chose Elastic Security because we felt it was the most flexible, cost-effective solution to provide the results needed.

Other products like Splunk are better than Elastic for a SIEM because there are some use cases already available for a client. Elastic doesn't have this, so the user must build the SIEM solution. I think that Elastic has to increase the features for the SIEM.

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.

Logging solution previously, but mainly I've been using Graylog and ELK. Graylog gives you centralized logging. It's built for a logging solution, whereas ELK is designed and built for more big data. If you want to go in deeper into analytics, ELK gives you that flexibility and out of the box models. The two solutions are widely used by a lot of bigger clients in the industry and they've been tried and tested.

In comparison with other similar solutions in the market, customers go with Elastic Security because of its scalability and its good performance. The solution has a good search feature, especially when a large volume of logs needs to be collected. Elastic Security also gives you pretty good results compared to other solutions.

Previously, we were on Datadog, Kubernetes Logs. It was not very easy to debug incidents and so on. If I had to compare, I'd say that Datadog is very easy to implement and it's such a fast solution.

We decided to use the solution because it was a very promising tool and other alternatives had limitations. The tool has availability, data infrastructure, data uptime, etc. The solution is quite flexible in terms of cost. You don't need to buy a license for each and everything. Whenever you require a license, you can just buy it. I think these are the two main drivers. The product is quite open in terms of integration with machine learning which helps us with proactive monitoring. 

I'm also aware of Curator. 

Compared to Curator, customer awareness isn't as strong. From the price perspective, this product is better, however, many customers don't want to change their own CM and their products if they already have something in place.

We used Splunk in parallel with this solution.

In my role as a Security Operations Center Analyst, I think that Splunk is more useful for me. This is because I do not work on analyzing application behavior. However, I help my colleagues with this task, using ELK Logstash, based on my experience with Splunk.

We're using the Microsoft Defender product. It's just what's embedded inside of the operating system. It's not the full Defender for Endpoint. It's just Windows and antivirus.

We previously used a product from Quest Software called Change Auditor. We actually didn't switch off this solution. We use both Quest and ELK in our organization.

The main difference is that one you have to pay for, while the other one is much cheaper and if you don't need all the features, you can use it for free.

ELK has much more information, as well. You can grab much more information with ELK than you can with Change Auditor, without adding any additional modules.

We didn't previously use a different solution.

We have used Graylog in the past, but it was self-hosted and the experience wasn't great.

I have used other similar solutions in the past.

We used Logentries, but because it is open-source we moved to ELK as a part of cost-cutting strategy and evaluation of ELK. But the lack of a notification feature caused us to go back to Logentries.

This was a solution that our client chose, and they were not using a different one prior to this.

We have used other SIEM solutions in our company.

I have used other SIEM solutions but this one is open-source, unlike some of the others.

It is also faster than IBM QRadar.
