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 tool's most powerful aspect is its search engine capability. It's a highly effective and powerful solution for searching. We use it in professional and student projects at universities, and it delivers promising results."
"The tool is huge, and it performs brilliantly. I tested it for malware, and within two weeks of launching, the product alerted me about a network intrusion. This was a tough test for it, but it performed admirably. The alerting system is excellent, and searching through logs is incredibly efficient. What's impressive is that all three products or options are integrated into one solution. This means I don't need separate logging, monitoring, or antivirus solutions."
"Elastic Stack has made a positive impact as we can now see our logs."
"Elastic Stack is mainly used to monitor servers and APIs. It helps ensure the software's availability and sends notifications at the right time so the system is not down for a long time. The tool's stability and advanced features, such as anomaly detection, are the most valuable features. The benefit of using it is real-time monitoring."
"It supports various integrations. It's open source and has excellent community support."
"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."
"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."
"The scripting model in Elastic Stack allows me to query logs and then put the data into Grafana."
"Splunk has saved our organization time by resolving problems in a quicker timeframe."
"Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language, allowing extensive customization and analysis capabilities."
"The search engine and indexes are fast and optimized, and the report generation dashboard is user-friendly."
"The solution is the market leader."
"I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features."
"It is lovely to have everything we need in one tool. Everything is quite centralized."
"I appreciate the Identity and Assets framework the most, as well as the threat analysis framework."
"Great platform with user-friendly interface and GUI."
 

Cons

"Elastic Stack should be more simplified with ready-to-use widgets."
"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."
"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."
"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."
"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."
"The tool's pricing can be improved."
"There could be better documentation."
"The main issue related to Elastic Stack is in the area of its licensing."
"There are some premium add-ons like Splunk Enterprise Security or ITSI which makes it more expensive."
"I rate the technical support of Splunk Enterprise Security as a three. I find it not good because whenever I raise a ticket, they take a very long time."
"The threat detection library needs to increase the frequency at which the playbooks are updated."
"The Splunk platform is not unified. We have all of these different tools and they feel a bit disjointed."
"I would like the ability to view logs for specific instances and not have to pull the logs for the entire Cloud environment in Splunk."
"The user interface is not user-friendly for non-technical users."
"There are limitations with Splunk not detecting all user activity, especially on mainframes and network devices."
"It does not give us permission to implement on-premise so we implement them on the cloud."
 

Pricing and Cost Advice

"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 pricing is reasonable."
"Ultimately, the pricing depends upon the capacity planning that the enterprise architect does."
"I used the open-source version of Elastic Stack, because of which I did not have to pay anything."
"We are using the open-source community version of the product."
"I rate the solution's pricing a six out of ten."
"The product is expensive."
"It depends on the specifics, but generally, Elastic is economical for certain use cases."
"There is an annual license required to use this solution."
"Pricing and licensing is quite expensive. But for the value the product provides, it seems at par in the market."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"From what I have seen so far, Splunk has multiple cost models. The one that we are using is pretty good when it comes to ingesting data into the environment. It has worked out pretty well."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"The subscription is monthly."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"It's a yearly subscription."
