A low-code/no-code platform with a user-friendly UI
We couldn't implement or use some of the latest functionalities, like Spark. Palantir Foundry is scalable, but it is costly compared to other cloud providers. The solution is more suitable for small and medium businesses. It might be difficult for large enterprises. I rate the solution’s scalability a seven out of ten.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

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

Pros

"The solution offers very good end-to-end capabilities."
"The virtualization tool is useful."
"The data lineage is great."
"Encapsulates all the components without the requirement to integrate or check compatibility."
"Palantir Foundry is a robust platform that has really strong plugin connectors and provides features for real-time integration."
"Live video sessions enhance the available documentation and allow you to ask questions directly."
"The predictive analytics capability within Palantir Foundry impacts financial forecasting strategies through its AIP functionality, which includes numerous pre-built models, LLMs, and data science application libraries."
"It's scalable."
"Overall, I would rate it a nine out of ten."
"It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture."
"Good for log collection and log management."
"Aggregation searches have reduced time and difficulty of identifying trends and conditions which need to reviewed."
"It gives me notifications of notable events."
"The solution is the market leader."
"Splunk has a wide range of features that customers use to find and analyze all kinds of logs."
"The benefits include the easy integration with other Splunk tools including Splunk UEBA, Splunk ITSI, and Splunk Core. The ease of integration and the organization's experience and familiarity with searching and passing logs through Splunk are the main benefits."
 

Cons

"Cost of this solution is quite high."
"The solution's visualization and analysis could be improved."
"It would be helpful to build applications based on Azure functions or web apps in Palantir Foundry."
"There is not a wide user base for the solution's online documentation so it is sometimes difficult to find answers."
"Compared to other hyperscalers, Palantir Foundry is complex and not so user-intuitive."
"They do not have a data center in Europe, and we have lots of personally identifiable information in our dataset that needs to be hosted by a third-party data center like Amazon or Microsoft Azure."
"The data lineage was challenging. It's hard to track data from the sources as it moves through stages. Informatica EDC can easily capture and report it because it talks to the metadata. This is generated across those various staging points."
"The major hindrance with Palantir Foundry is that being a very closed product, the cost optimization and costing are not exposed to the end users."
"I would like to see ability to master management. In terms of clustering, how it manages clustering needs improvement."
"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations."
"It'd be really nice if Splunk Enterprise Security had a better and solid configuration guide."
"Splunk Enterprise Security can provide more details and help CISOs resolve vulnerability situations better. The reason is that the tools we choose for data analysis and log collection cannot collect all the data and logs. Splunk Enterprise Security should help me with this, but it cannot."
"The solution could improve by increasing the performance. We have run into problems when large amounts of data are processed."
"The only thing which can be improved is that they are too subjective on whom their Splunk4Good initiative can be applied. They market it as you only need to be a nonprofit, but there is more to it."
"I find that the learning curve for Splunk is relatively lengthy."
"Splunk does not provide any default threat intelligence like Microsoft Sentinel, but you can integrate any third-party threat intelligence with Splunk. By default, no threat intelligence suite is there, whereas, with IBM QRadar or Microsoft Sentinel, the default feature of threat intelligence is there. It is free. If Splunk can provide a default threat intelligence suite, it would be better."
 

Pricing and Cost Advice

"Palantir Foundry has different pricing models that can be negotiated."
"Palantir Foundry is an expensive solution."
"It's expensive."
"The solution’s pricing is high."
"Splunk is definitely not a cheap solution. It is an expensive product."
"ROI is estimated at saving my team roughly 10 to 12 man hours per week in troubleshooting for our company as well as what our profits had been from our services of installing, configuring, and supporting other clients with the product."
"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."
"The variables and the flexibility that Splunk provides are helpful, especially in a hybrid and multi-cloud environment."
"Splunk Enterprise Security is expensive."
"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."
"The price is comparable."
"Splunk Enterprise Security is affordable."
