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 solution offers very good end-to-end capabilities."
"Great features available in one tool."
"It is easy to map out a workflow and run trigger-based scripts without having to deploy to another server."
"Palantir Foundry is a robust platform that has really strong plugin connectors and provides features for real-time integration."
"The solution provides an end-to-end integrated tech stack that takes care of all utility/infrastructure topics for you."
"It's scalable."
"The data lineage is great."
"The AI engine that comes with Palantir Foundry is quite interesting."
"The feature that I have found most valuable with Splunk is the ability to sift through a bunch of data very quickly."
"Deployment server for deploying changes in one go."
"Its alerting is most valuable. We have alerts set up in our environment for certain attacks, such as an SQL injection attempt. We have a front-facing server for the website. It is out there, and anybody can access it. When those SQL injection attempts come in, we are able to detect that with the alert."
"The most valuable features are how stable and easy to use Splunk is."
"The alerts are very effective."
"They are a good partner for Google Cloud. It provides great visibility, threat detection, and proactive mitigation of risks for our mutual consumers."
"It is very stable. We have not had any problems."
"Overall, I would rate it a nine out of ten."
 

Cons

"The startup pricing is high, causing concern despite being cost-effective in terms of total cost of ownership."
"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."
"The solution’s data security could be improved."
"Difficult to receive data from external sources."
"The frontend capabilities of Palantir Foundry could be improved."
"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."
"Some error messages can be very cryptic."
"Compared to other hyperscalers, Palantir Foundry is complex and not so user-intuitive."
"The UI could be better. This is applicable to Splunk in general. I know that a lot of people who get their hands on Splunk are hesitant to use it just because they find it overwhelming. There are a lot of options."
"If you have to do your own stuff, such as customized charts, it is a little bit more work, but once you're familiar with the Splunk query language, you can pretty much do whatever you want. In terms of features, it should probably have the features that other competitors provide."
"There are limitations with Splunk not detecting all user activity, especially on mainframes and network devices."
"It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive."
"I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team."
"Professional support is great, but too expensive."
"It's missing some features that other solutions have, such as the ability to upgrade the endpoint and perform endpoint universal forwarders from a deployment server instead of using a third-party solution, such as Puppet or Ansible."
"Its search or filtering capability is nice, but it can be improved. It is currently a bit complicated, and it should be simplified. If we can write the search filter in a more simplified way, 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."
"The solution is costly."
"I have no opinion on pricing."
"Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
"Its pricing model can be improved."
"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 is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
"Splunk should be able to integrate with other product using the free version."
"The pricing model is expensive and a nightmare based on the amount of data."
