Between our warehouse systems, fleet tracking, logistics portals and cloud apps, there's a flood of data every second. Splunk ES is the connector that pulls all that into one view. The company handles freight for a couple of government clients. We are therefore required to prove that all access and data transfers are monitored. Splunk's audit dashboards make that less painful
Pros
The dashboards are super flexible. We've built custom ones for different teams with so much ease
Correlation search feature is superb
Risk based alerting
Cons
The more data you feed it the more maintenance it needs and the cycle never stops but storage costs keep spiking.
Data onboarding is harder than it needs to be. We are always forced to contract partners whenever we're bringing in a lot of logs
Likelihood to Recommend
Splunk is powerful, no doubt about that but it also demands way too much attention. I'd recommend it to teams that have a decent handle on their data flow. As for us, we're still struggling to get ahead of the data situation but Splunk's complex data ingestion gateway isn't making that any easier.

It's easy to build queries & integrate with other systems and applications. There are a lot of add ons you can integrate to Splunk that can save you a lot of time. Correlation and investigation are easy due to Splunk's effective data parsing capability. There are endless options to customize searching. It provides a very accurate Data Analytics platform that can be adopted by users of all levels. E.x. From tools like Data Tables for Novices to Splunk's Web Framework for Experts.
Pros
It gives visuals to the client when we select a graphical portrayal, enabling us to change signs into visual outlines, for example, pie outlines, diagrams, tables, and so on.
Dashboard UI is intuitive and exceptionally educational, so one can easily find whatever they are looking for.
Cons
Sometimes, it's very, very slow! It also takes a long time to refresh.
UI for pattern searching can be a little better.

Well Suited: What we admire most about Splunk is the significant improvements and capabilities it brings to the software with every major release. It is simply mind-blowing and easy to set up from a backend developer's point of view, as it is compatible with existing popular enterprise frameworks using microservice architecture (Spring Boot). Less Suited: Their enterprise plans are frankly costly. Cost wise, maybe it won't be suitable for small startups.
We use Splunk Enterprise in our Organization to achieve the following. Consolidate logs from all sources in one place. Create Custom Correlation alerts to paint the bigger picture effectively. Create Sophisticated Dashboards and reports using multiple data sources for better and non-redundant visualization. Create some basic automation like CSV updates. Perform Threat Hunting to discover unknown threats. Manage Incidents in one place and track Analyst Performance.
Pros
Writes Powerful Queries: The queries that can be written using the Splunk Query Language are very powerful and highly customizable to meet every need. Ex: Writing queries to search the intersection of two different sources like Network and Endpoint Logs.
Offers Dashboard Abilities: Helps build complex panels for Dashboards in addition to providing several out-of-the-box panels. Ex: creating panels to calculate the performance of analysts in a given timezone.
Helpful Search Aids: It helps to set up complex custom alerts very easily. The interesting fields section is very helpful while threat hunting. Ex: It shows all the users and the frequency of each in a failed login event. The user list on the interesting fields is useful to look for suspicious logins.
Cons
Dashboard Builder: It needs more out-of-the-box panels for beginners to learn.
Autofill: The query autofill isn't that great. It needs better suggestions for beginners especially.
Speed: The speed of the search isn't that great. It can be improved. For some queries, it takes too long.
Error handler: The error messages in the case of wrong syntax can be more descriptive. The messages are sometimes vague and are not helpful.
Likelihood to Recommend
Well suited: Splunk ES is highly recommended in an environment with many data sources and experienced computer engineers. It has a steep learning curve, but once that hurdle is crossed, it is absolutely a beast. It is also very expensive, so a company putting a high amount of budget in Security is needed. Not well suited: Splunk ES is not recommended if a company has only a few sources and some non-technical IT users. The price won't justify the fewer data sources and scratching just the surface level. Moreover, non-technical IT users would be better off with something that has a query builder, unlike Splunk.

I was evaluating Splunk for a potential client. Splunk is a great tool for anyone that needs a SIEM to monitor data, networks, users, etc. The customization of the Dashboard is ideal for anyone to setup and use for an easy display of information. The alerts are incredibly helpful for notification of any problems
Pros
Develop dashboards and notables to track security-relevant details
Data correlation
threat monitoring and detection
Cons
more efficient searches
Multiple ways of creating report and alert is confusing
Multiple ways of creating report and alert is confusing
Likelihood to Recommend
It is very easy to connect data sources and manipulate data sets of any size
I use the product to help monitor, analyze and potentially mitigate certain security issues that may come up. This includes acting as a secondary for escalations and looking at some alerts. I also use it to action on data that may be of use to our organization. It is helpful to organize alerting and easy to take action.
Pros
Monitoring log activity for potential security problems
The interface for investigations is pretty easy to use
Enjoy the high level detail the product gives for alerting
Nice playground for keeping track of investigations
Ease to create new notables to track further items.
Cons
Crazy awful latency when loading
Sometimes the events tab won't show any logs
Difficult to follow certain parts of investigations, but this is being addressed with Mission Control. (I'm talking about the original interface)
Confusion about where to easily navigate to view what items make up risk score as the interface can be confusing.
lowering risk score is extremely obnoxious.
Likelihood to Recommend
I like how it's all one dashboard and there is not a separate SIEM from the actual log agregator. This makes investigation a lot more efficient and easy to complete said investigation. It is easy to close multiple alerts together and to link items when the notables are part of an overarching issue. It is also easy to make another notable. It is easy to change the risk score to lower the alerting threshold.

splunk ES is a very useful and powerful tool as a SIEM platform, we send logs from multiple sources such as winodws servers, linux, RH, Firewalls, WAF, O365, etc, the installation process of UF is not complicated, the deployment of the information is fast and the language for the visualization of tables or graphs can be a little complicated but there are guides and KB to support these tasks.
Pros
Customization of dashboards
Creating apps based on your needs.
Search queries can be saved for future or even can be converted to apps
Cons
high cost
slow interface
