Featured Reviews

Shitanshu Kumar - PeerSpot reviewer
Offers insights into past events and future incidents before they occur
I rate the product a nine out of ten. Organizations should evaluate how the solution will impact their organization and align with their security goals rather than solely focusing on the features the solution offers. The capabilities of a solution may vary, and it's essential to prioritize your specific requirements and choose the one that best meets those needs.
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 product provides a collective view through the Enterprise Security Manager, offering insights into past events and heuristics about future incidents before they occur and impact the organization."
"The product has a good security posture."
"It is a very stable solution. I never really had a hiccup with the tool."
"The consolidated overview of all the events that come in through our environment and an easy-to-access interface for all our end users are valuable."
"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."
"It's basically one of the best SIEM products on the market."
"The most valuable feature is the incident dashboard, and the extensive use of correlation searches, which isn't available with a standard Splunk search package. This feature is important to me because it enables SOC analysts to do their job more efficiently and be able to investigate or mediate incidents at a faster pace."
"It provides a risk score for each object, device, or user. We can then take action if they are at a higher risk."
"It's better than IBM, in my opinion, because it's an independent entity."
 

Cons

"ArcSight Security Open Data Platform needs to improve stability. Support has deteriorated after the acquisition of OpenText. It should also improve market awareness."
"The pricing can be better."
"Due to its high licensing cost, Splunk is out of reach for many organizations."
"Splunk's implementation process for managing multiple indexes can be complex, especially when dealing with a large number of components."
"Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard."
"AngularJS/ReactJS inclusion could be made easier in GUI."
"The implementation and the scanning of the logs can be difficult."
"Sometimes, there is latency in the logs."
"One thing that I probably dislike the most about the Splunk product is their support."
 

Pricing and Cost Advice

Information not available
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"Splunk is priced higher than other solutions."
"Splunk is not a cheap solution and the license is billed annually."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"The licensing is good, but the pricing absolutely needs some work. It is very high."
"It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits."
"The tool's licensing is good and we haven't received any complaints from the team handling it."
"It's definitely worth it."
