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 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."
"The only beneficial aspect of Elastic Stack is that it's open source."
"Elastic Stack has made a positive impact as we can now see our logs."
"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."
"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 machine learning capabilities are valuable."
"Splunk Enterprise Security offers two valuable features: the Common Information Model and arrangement modules."
"The solution has improved our organization by providing a comprehensive picture of any external threats to the operating system and improves asset control."
"Splunk has a wide range of features that customers use to find and analyze all kinds of logs."
"The ability to manipulate data in Splunk is unparalleled."
"The most valuable features of Splunk Enterprise Security are its high-performance data collection, flexible query language, and its versatility across the organization."
"When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information."
"When we use a centralized log monitoring system we can see things on the dashboard and it is easier for the IT manager or an IT engineer to take corrective action in the system."
"Three features stand out for me: the SDK for writing Python, the customizable and adaptable diagnostic dashboard, and the optimizer for collecting data."
 

Cons

"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."
"It should facilitate easier manual integration."
"Elastic Stack should work on their dashboards and integration process."
"It lacks a clear NDR (Network Detection and Response) feature. If Elastic could enhance this aspect, it would significantly boost its capabilities."
"Improvements are needed in the solution in areas like SOAR and TIP, where there are certain shortcomings."
"The stability of the solution is rated as three or four out of ten as we frequently encounter issues."
"Support could be improved. The error code is not helpful. We have to ask for it or pass it on to community forums."
"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."
"I want Splunk Enterprise Security to release more AI and machine learning features in the future."
"Stability is there, but every release has some bugs."
"I think the tech support response time could be a bit better. Sometimes I need to wait more than 24 hours for a response to my tickets."
"When we were trying to implement an enterprise solution on-premise, we had scaling issues."
"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."
"The threat detection library needs to increase the frequency at which the playbooks are updated."
"It would be great if I could have a certain dialogue box in Splunk that uses innovative AI tools like ChatGPT, which are available now in the tech department."
"We would like more integrations with other cloud products, not just AWS, e.g., Azure."
 

Pricing and Cost Advice

"The pricing is reasonable."
"Ultimately, the pricing depends upon the capacity planning that the enterprise architect does."
"It depends on the specifics, but generally, Elastic is economical for certain use cases."
"The product is expensive."
"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."
"I rate the solution's pricing a six out of ten."
"If I compare Elastic Stack to the other products in the market, I would say that the tool is available at a competitive price."
"Splunk should be able to integrate with other product using the free version."
"Its price is fair. Like with anything else, if you go into the cloud, different providers cost more, and you are able to throttle back or throttle up. The cost is comparable with anything else."
"It is not cheap."
"I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper."
"Expensive compared to other options."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
