What is our primary use case?
I have implemented
Elastic Search in my organization. My experience has been really good with
Elastic Search regarding the dashboards and alerts. They have integrated AI/ML capabilities in it. 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.
Another feature is image vector analysis, which can authenticate images to prevent impersonation frauds in the ecosystem. This is a major use case in personal information and identifiable information portfolio.
I'm using Elastic Search as an observability tool and a SIEM tool. The indexing, searching, fast indexing, alert mechanisms, and BCDR compatibility are pretty smooth with Elastic Search.
On the resourcing part, I have cut off a good amount. While I don't have a concrete percentage to mention precisely, it has reduced resources to some extent.
What is most valuable?
Attack Discovery is the first feature that I appreciate. It is truly an amazing feature for any
SIEM to have inbuilt. The image vector analysis is another feature that identifies any manipulation done to images. It can authenticate and identify authenticated images. If there are 10 duplicate and forged images, it can identify them through vector-based searching capabilities. These two features are prominent in terms of SIEM capabilities that Elastic Search has.
I can share feedback from the SIEM perspective about Elastic Search, as I had evaluated Elastic Search, LogRhythm, QRadar, and Microsoft.
What needs improvement?
More AI would be beneficial. I would also appreciate more simplicity in dashboards. A comprehensive dashboard is something I could expect.
For how long have I used the solution?
I have been using Elastic Search for a year now.
What do I think about the stability of the solution?
There are no limited parameters to search from the events perspective. When you put one keyword, everything related to that keyword in your ecosystem will showcase all the results. This helps to get into the granularity of any events happening across the system.
What do I think about the scalability of the solution?
It has gained significant visibility. Comparing alert statistics from other SIEMs where they could trigger 50 alerts on average weekly, Elastic Search has given me alerting statistics of roughly 90 plus for a week's time. All those alerts are mapped to MITRE ATT&CK framework. Though it could result in false positives in the earlier stage until you fine-tune and streamline the use cases in your SIEM, which is common with all SIEM tools, the visibility that Elastic Search has given us is amazing.
How are customer service and support?
It was a direct purchase.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We previously used an on-premises solution.
How was the initial setup?
The setup complexity depends upon the engineering team doing the implementation and the kind of infrastructure you have where logs will be ingested into the solution. For us, it was time-consuming in the earlier stages, but it was manageable and not overly complex.
What was our ROI?
We have seen moderate returns on investment.
What other advice do I have?
As a CISO, I review and do the governance part. I receive alert notifications, but I don't work directly with the tool. None of my team members have complained or proposed any feature changes or modifications to the existing solution.
It totally depends upon the nature of business you are in. For my organization, it was imperative to have image scanning in place and identifying frauds happening with PII. From that perspective, Elastic Search has played a vital role. It has good inbuilt EDR capabilities as well, making it a good-to-go tool.
I rate Elastic Search eight out of ten.
Which deployment model are you using for this solution?
