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

"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."
"I have experienced a return on investment from the use of the solution."
"It is an excellent tool for monitoring purposes."
"The scripting model in Elastic Stack allows me to query logs and then put the data into Grafana."
"I think the ecosystem is well supported, and for logs, it was faster compared to our previous previous log management."
"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."
"The machine learning capabilities are valuable."
"The biggest strength of Elastic Stack is its brilliant archiving capabilities."
"The feature I appreciate the most about Splunk Enterprise Security is the CIM data model, which allows users to bring in data from different technologies, such as firewalls, endpoints, and perimeter DMZs, enabling every device to pump data into Splunk Enterprise Security, with the data model normalizing all the data and placing it in a common plane."
"Splunk Enterprise Security's value lies in its ability to collect and analyze security logs, providing insightful dashboards."
"I like the Splunk dashboard and search engine."
"It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture."
"The solution's newly developed dashboard is pretty amazing."
"The dashboard and reporting are very good... It provides very good visibility in a hybrid cloud environment, and you can build custom utilization APIs using Splunk."
"We did not encounter any issues with scalability. It is almost seamless to add new index (storage) or search (used to analyze the data) nodes to the cluster."
"What I appreciate about Splunk Enterprise Security is creating the newest SPL for network traffic and using the risk-based alerting feature that helps my organization by allowing me to learn more information about Splunk every day because it is a big platform."
 

Cons

"The implementation of dashboards in the solution needs to be made easier...I had some issues with the ports and configuration since it was kind of complex to implement with Docker."
"There could be better documentation."
"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."
"The tool's pricing can be improved."
"It should facilitate easier manual integration."
"Improvements are needed in the solution in areas like SOAR and TIP, where there are certain shortcomings."
"The main issue related to Elastic Stack is in the area of its licensing."
"Due to its high licensing cost, Splunk is out of reach for many organizations."
"Free-floating panels in the dashboards are like a glass table."
"It is very complicated to write your own correlation rules without the help of Splunk support."
"Better directions on search head clusters."
"The solution could improve by giving more email details."
"Splunk's reporting functionality would benefit from enhanced customization capabilities, allowing users to tailor reports to their specific needs for better data visualization and analysis."
"I find that the learning curve for Splunk is relatively lengthy."
"The main improvement needed in Splunk Enterprise Security is its system visibility after installation."
 

Pricing and Cost Advice

"I used the open-source version of Elastic Stack, because of which I did not have to pay anything."
"It depends on the specifics, but generally, Elastic is economical for certain use cases."
"The pricing is reasonable."
"I rate the solution's pricing a six out of ten."
"We are using the open-source community version of the product."
"Ultimately, the pricing depends upon the capacity planning that the enterprise architect does."
"If I compare Elastic Stack to the other products in the market, I would say that the tool is available at a competitive price."
"The product is expensive."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."
"It is economical than other solutions."
"Truly evaluate the data you want to ingest and go slow. Pulling in data that can provide no use to your mission only wastes data against your license."
"Splunk Enterprise Security is expensive."
"The pricing modules could be improved."
"It can be expensive, especially the licensing costs. However, there is added value in what it can do, not just log aggregation."
"It can be tough to determine if you are getting all of the value out of your investment at times."
