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 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."
"I like the data onboarding to Palantir Foundry and ETL creation."
"Encapsulates all the components without the requirement to integrate or check compatibility."
"The security is also excellent. It's highly granular, so the admins have a high degree of control, and there are many levels of security. That worked well. You won't have an EDC unless you put everything onto the platform because it is its own isolated thing."
"The virtualization tool is useful."
"The data lineage is great."
"The solution provides an end-to-end integrated tech stack that takes care of all utility/infrastructure topics for you."
"The solution offers very good end-to-end capabilities."
"We can do things in minutes instead of days."
"We can easily configure things as required in relation to our use cases."
"From my experience, the visual aid that it provides is most valuable. There are charts and other means to provide information."
"We can present to our management in real time the security of the batch management for the PCs, security regarding the network equipment. We're currently working in the Azure Cloud project, so we can send any logs from the cloud to Splunk. We can monitor them and we can present to the managers and customers. It's a very good solution for reporting. We use Splunk for reporting and monitoring of any solution in the company."
"Out-of-the-box, it seems very powerful."
"Capability to expand the functionality through custom code for data inputs, commands, visualization, alerts, and machine learning."
"It has the ability to correlate data, analyze and review it."
"It definitely does help with both auditing and as well as regular monitoring. SOC does more monitoring, but ES also gives you other features that are auditing-related. The dashboards are also beneficial."
 

Cons

"Compared to other hyperscalers, Palantir Foundry is complex and not so user-intuitive."
"It would be helpful to build applications based on Azure functions or web apps in Palantir Foundry."
"If you want to create new models on specific data sets, computing that is quite costly."
"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."
"It requires a lot of manual work and is very time-consuming to get to a functional point."
"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."
"Some error messages can be very cryptic."
"The frontend capabilities of Palantir Foundry could be improved."
"The cluster environment should be improved. We have a cluster. In the Splunk cluster environment, in the case of heavy searches and heavy load, the Splunk cluster goes down, and we have to put it in the maintenance mode to get it back. We are not able to find the actual culprit for this issue. I know that cluster has RF and SF, but it has been down so many times. There should be something in Splunk to help users to find the reason and the solution for such issues."
"It requires a significant amount of relatively complex architecture once you push past the single server instance."
"I find that the learning curve for Splunk is relatively lengthy."
"More training on PetaData using artificial intelligence techniques to identify the events which are not normal and exceptions that would help the organization identify threats and malware on the go with results."
"Deployment is not difficult but the lock sources and configurations can take time."
"It currently has limited default rules and customizations. If they can concentrate more on the compliance part and the security information part, it would be helpful. The platform part is good, but it requires many features from the security aspect."
"The GUI can be improved. Splunk has always suffered from having a kind of goofy UI, it needs some updating."
"I'd love to see more integrations, which is one of the primary points of the key node with Splunk Enterprise Security."
 

Pricing and Cost Advice

"Palantir Foundry has different pricing models that can be negotiated."
"Palantir Foundry is an expensive solution."
"The solution’s pricing is high."
"It's expensive."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"Splunk Enterprise Security's pricing is pretty competitive."
"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."
"Pricing is probably its weakest spot. As compared to some competitors, Splunk is really expensive."
"It is not cheap."
"It is expensive, but it is a good tool. It is worth the cost."
"The solution is a little expensive."
"Splunk Enterprise Security is an expensive solution."
