Executive SummaryUpdated on Jan 25, 2026

Splunk Enterprise Security and Elastic Stack are competing products in the realm of security analytics and SIEM solutions. Splunk Enterprise Security appears to have a slight advantage due to its extensive features and options for customization and use across various environments, whereas Elastic Stack provides a more economical solution with powerful capabilities, particularly in real-time search and machine learning.

Features: Splunk Enterprise Security showcases rapid search and schema-on-read technology, equipped to manage large data volumes. It supports detailed security analytics along with customizable dashboards and integrations for operational intelligence. Elastic Stack is recognized for its robust real-time search capabilities, machine learning focus for security monitoring, anomaly detection, and scalability, making it adaptable and customizable.

Room for Improvement: Splunk Enterprise Security could enhance its visualization tools, ease of setup, and operational workflows for security operations. Users face challenges with the steep learning curve and optimizing performance under heavy loads, necessitating better documentation and efficient technical support. Elastic Stack needs improvements in integration, a more intuitive user interface, enhanced network detection, and response capabilities, alongside simplifying its licensing model and developing advanced AI features.

Ease of Deployment and Customer Service: Splunk Enterprise Security offers varied deployment options across cloud and on-premises with a strong community presence, though technical support inconsistency is noted. Its support resources are extensive, but resolving complex cases often requires escalation. Elastic Stack, suited for diverse environments, benefits from detailed community support and comprehensive documentation, but lacks personalized technical assistance, which may affect user experience.

Pricing and ROI: Splunk Enterprise Security is perceived as costly, with fees based on data ingestion and requiring extra licensing for extended features. Despite its significant ROI in analytics, many find the cost a barrier. Conversely, Elastic Stack is seen as more cost-effective, particularly due to its open-source components, offering competitive pricing for businesses that leverage its extensive scalability and functionality for different use cases.

Senior Consultant at Skillfield

Offers robust out-of-the-box integrations and streamlines logging processes effortlessly

There are improvements needed for Elastic Stack. It is mostly based on Lucene, and the heart of Elastic Stack is Lucene, which has some limitations. Anything built on top of Lucene often feels an add-on, and that includes vector databases. Elastic Stack can store vector embeddings as well and perform AI and machine learning tasks out of the box without excessive configuration. The main improvements involve increasing speed and compression capabilities; I have seen databases that claim to achieve significantly better compression. While Elastic Stack can manage vast amounts of data, if the mapping is not specified correctly, the indexing time can be slow, especially with many events per second. Improper mapping usually means that every document received gets indexed for all fields, which is not desired. Elastic consultants typically optimize this, but out of the box, as data volume increases, scaling becomes necessary. They are working on these improvements in new versions.

Helps us detect cyber threats quickly and integrate multiple feeds effectively

Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"The detection rules in Elastic Stack are the most valuable feature. The search capabilities are excellent and fast. As we collect logs from workstations and devices, the detection rules run on top of the logs and detect any suspicious activity, raising alerts accordingly. Integration with Elastic Stack depends on the specific integration. Elastic provides some bridging integrations that make it easy, but require custom integration. Most integrations are simple, but customization can be challenging because we need to do some parsing. There's something called Elastic Common Schema, and we need to parse the source logs to match this schema, which can be a bit challenging."

"We can group a lot of alarms into one automation alarm supervision. The alarm supervision allows us to put the alarm under the same. It's quite helpful for us. We used that to suppress our alarms. Elastic already provides the agent. It is easy to integrate Elastic Stack with other devices and vendors."

"I have experienced a return on investment from the use of the solution."

"The biggest strength of Elastic Stack is its brilliant archiving capabilities."

"The machine learning capabilities are valuable."

"Prior to the latest updates, data lake management was a standout feature. The hybrid capability for on-premise and cloud integration was also crucial. Now, with Elastic Defense, the agent simplifies security monitoring, making it a key asset."

"I have benefited from the security features provided by X-Pack in Elastic Stack, particularly the SIEM capability, which is very good for checking security issues."

"The centralized logging capabilities of Elastic Stack have helped me streamline my logging processes significantly because there are many open-source tools available, such as Filebeat and Logstash, to collect the logs."

More Elastic Stack pros

"We can easily configure things as required in relation to our use cases."

"The risk-based alerting (RBA) is one of the valuable features."

"The correlation searches (properly configured) populate the Incident Management dashboard and provide me a quick birds-eye view of my most important concerns."

"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."

"Splunk Enterprise Security is a huge value-add to us because I can confirm that our security team treats it as a normal component of their daily operations."

"Recently, Splunk upgraded to version 9.0.02, which includes excellent data dashboards and visualization effects."

"The solution's most valuable feature is the incident review, which gives a good overview of our security incidents."

"It's a great investment, especially if you want to strengthen your security stance."

More Splunk Enterprise Security pros

Cons

"I would rate the technical support by Elastic as five or six out of ten. They should improve their response time and first-level support, particularly knowledge, which is very important for using Elasticsearch."

"Improving integration capabilities, especially with authentication systems, firewalls, and security controls, is a crucial area for improvement in Elastic Stack. Additionally, enhancing functionality to handle large Yara queries more efficiently would be beneficial, as many EDR solutions can run such queries faster than Elastic Stack's current limitations."

"When people try to move the data from another source to Elastic Stack for visualization, they face challenges when connecting to Elastic Stack from such different sources."

"The stability of the solution is rated as three or four out of ten as we frequently encounter issues."

"The main issue related to Elastic Stack is in the area of its licensing."

"Elastic Stack should be more simplified with ready-to-use widgets. Also, incorporating AI capabilities is essential as monitoring and observability tools are now adding AI features."

"Elastic Stack's search capabilities can be challenging, especially when searching for precise data from past years, such as two or ten years ago. Its indexing performance for exact data retrieval may decrease as the data volume grows. Therefore, I believe there is room for improvement in the product's search functionality. It needs to improve its pricing as well."

"Elastic Stack should be more simplified with ready-to-use widgets."

More Elastic Stack cons

"The use cases provided by Splunk are a good starting point, but could cover many additional topics to ensure that a smaller or less experienced shop might maximize the value of an ES deployment."

"Splunk Enterprise Security can be improved with better triage capability and less dependency on running SPL searches, which would allow analysts who may not have much experience in writing SPL searches to still use the tool and run investigations."

"The problem with the product is that the price of Splunk is very high."

"The documentation and training resources available for knowledge and training can be expanded. We need to learn more about Splunk Enterprise Security and new security attacks."

"Splunk Enterprise Security can be improved with more ease of configuration."

"The ingestion happens quickly, so you can run up the data costs if you use the default settings. It isn't a problem for government agencies in the Saudi market, but many of the corporations in India are small or medium-sized enterprises that cannot afford that kind of ingestion system."

"Splunk Enterprise Security is great but can have some frustration points. It can sometimes be slower to use."

"Splunk Enterprise Security does throw some false positives. It, as anything, needs some tuning."

More Splunk Enterprise Security cons

Pricing and Cost Advice

"The pricing is reasonable."

"If I compare Elastic Stack to the other products in the market, I would say that the tool is available at a competitive price."

"It depends on the specifics, but generally, Elastic is economical for certain use cases."

"The product is expensive."

"I rate the solution's pricing a six out of ten."

"We are using the open-source community version of the product."

"I used the open-source version of Elastic Stack, because of which I did not have to pay anything."

"Ultimately, the pricing depends upon the capacity planning that the enterprise architect does."

"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."

"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."

"Our ROI is high."

"Splunk Enterprise Security incurs a significant cost because of the amount of data we send, but we are fine with the value we're getting for that price."

"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."

"It's more expensive than the other tools, but it's worth it. Every penny is worth it."

"Splunk Enterprise Security is a bit expensive overall, but it provides good value."

"The licensing costs are high for Splunk Enterprise Security."
