Rama Subba Reddy Thavva - PeerSpot reviewer
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 interface is really user-friendly."
"Palantir Foundry is a robust platform that has really strong plugin connectors and provides features for real-time integration."
"It is easy to map out a workflow and run trigger-based scripts without having to deploy to another server."
"The data lineage is great."
"The virtualization tool is useful."
"The ease of use is my favorite feature. We're able to build different models and projects or combine different projects to build one use case."
"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."
"Encapsulates all the components without the requirement to integrate or check compatibility."
"Splunk has machine learning which is a valuable feature."
"The correlation capabilities are the first value that our clients say they like with Splunk."
"We can do things in minutes instead of days."
"Splunk Enterprise Security's value lies in its ability to collect and analyze security logs, providing insightful dashboards."
"Splunk Enterprise Security helped us with faster detection of threats."
"The completeness of the solution is what we like the most."
"Recently, Splunk upgraded to version 9.0.02, which includes excellent data dashboards and visualization effects."
"It helps us uncover bottlenecks in the network."
 

Cons

"Difficult to receive data from external sources."
"The frontend capabilities of Palantir Foundry could be improved."
"The startup pricing is high, causing concern despite being cost-effective in terms of total cost of ownership."
"There is not a wide user base for the solution's online documentation so it is sometimes difficult to find answers."
"It would be helpful to build applications based on Azure functions or web apps in Palantir Foundry."
"It requires a lot of manual work and is very time-consuming to get to a functional point."
"Some error messages can be very cryptic."
"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."
"Many of my clients want to get better at Splunk, but they're afraid of using the tool because they feel it's too complex for them."
"Splunk could add more ways to manage archiving and storage. There isn't a web interface. You can do this on the SaaS version, but the on-premise platform doesn't have this option. It has other things but no option for remote NAS. I would like to have a personal web interface where I can specify how long logs should be stored. To have this readily available on the web, you need to adjust some settings on the backend. That is tricky."
"I didn't face any major issues with Splunk Enterprise Security. There were only one or two issues related to the user account, but nothing major."
"Splunk could enhance its offerings by incorporating modules for network detection and response and fraud management, along with improving its threat intelligence management capabilities."
"Splunk could be improved by reducing the cost. The cost is one of the biggest challenges for us in keeping to our production requirements."
"I haven't found a way for me to create my own plugins and integrate them into Splunk, but this isn't necessarily a limitation; it could simply be a lack of knowledge on my part."
"One area Splunk Enterprise Security fails to improve is the pricing aspect; while the initial pricing seems fine, the licensing cost can skyrocket over time, creating trauma for organizations."
"Most importantly, Splunk can be outrageously expensive. That is the problem with both Splunk and Sentinel. Their pricing literally explodes based on the amount of data you feed in."
 

Pricing and Cost Advice

"The solution’s pricing is high."
"Palantir Foundry is an expensive solution."
"It's expensive."
"Palantir Foundry has different pricing models that can be negotiated."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"The license for Splunk Enterprise Security is expensive."
"Splunk is costly but it’s worth it due to the high-end features."
"The pricing and licensing of the product are quite high."
"Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"Splunk licensing model might seem expensive but with all the gain in functionalities you will have compared to traditional SIEM solutions I think it’s worth the price."
"The pricing is very complicated, and it is very pricey. You do require a lot of different licenses in order to get a comprehensive solution that is not just the SIEM solution."
