Unified search has powered feature‑driven research with minimal maintenance overhead
We haven't had the opportunity to use the hybrid search with Elastic Search yet. I think there's a place for it in our long-term solution, but we're not quite there yet. We haven't yet used any AI features built into Elastic Search. To do what we want to do with Elastic Search, the queries can get complex and require a fuller understanding of the DSL. Once we start to build that understanding, it's another muscle we have, so it's not a bad thing, but it just takes a while to get up and running with expertise for our engineers. It's not hard to learn how to use more complex things in Elastic Search; it's just a challenge we're going to face.

Robust solution with good value
Microsoft FAST is quite robust. Our clients are quite happy with it. For other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components. If you are with any other third party, there could be a chance that the required output is not what you would expect. But with Microsoft, it will work better. It is compatible with the older generation systems, so you can offer it. On a scale of one to ten, I would give Microsoft FAST an eight because I'm quite comfortable with it.

Quotes from Members

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

Pros

"The tool's stability and performance are good."
"The Attack Discovery feature helps to dig into incidents from where they occurred to determine how the incident originated and its source; it gives an entire path of attack propagation, showing when it started, what happened, and all events that took place to connect the entire cyber incident."
"I have found the sort capability of Elastic very useful for allowing us to find the information we need very quickly."
"It is a stable and good platform."
"The initial setup is very easy for small environments."
"I like how it allows us to connect to Kafka and get this data in a document format very easily. Elasticsearch is very fast when you do text-based searches of documents. That area is very good, and the search is very good."
"I appreciate the indexing capabilities and the speed of indexing in their product, which demonstrates how quickly logs are collected and stored."
"The best feature of Elastic Search is it does exactly what it says."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
 

Cons

"I would rate the stability a seven out of ten. We faced a few issues."
"While integrating with tools like agents for ingesting data from sources like firewalls is valuable, I believe prioritizing improvements to the core product would be more beneficial."
"I have not been using the solution for many years to know exactly the improvements needed. However, they could simplify how the YML files have to be structured properly."
"Machine learning on search needs improvement."
"There should be more stability."
"I would like to be able to do correlations between multiple indexes."
"The documentation for Elastic Search can be challenging if you're not already familiar with the platform."
"Elastic Search needs to improve authentication. It also needs to work on the Kibana visualization dashboard."
"If there is any change in a system or a configuration or an update, we might face some issues."
 

Pricing and Cost Advice

"​The pricing and license model are clear: node-based model."
"I rate Elastic Search's pricing an eight out of ten."
"We are using the free version and intend to upgrade."
"We are using the Community Edition because Elasticsearch's licensing model is not flexible or suitable for us. They ask for an annual subscription. We also got the development consultancy from Elasticsearch for 60 days or something like that, but they were just trying to do the same trick. That's why we didn't purchase it. We are just using the Community Edition."
"The solution is less expensive than Stackdriver and Grafana."
"The price of Elastic Enterprise is very, very competitive."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."
"We are using the free open-sourced version of this solution."
