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."
"I think the ecosystem is well supported, and for logs, it was faster compared to our previous previous log management."
"Elastic Stack has made a positive impact as we can now see our logs."
"The biggest strength of Elastic Stack is its brilliant archiving capabilities."
"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."
"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."
"It is an excellent tool for monitoring purposes."
"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."
"It scales better in the cloud than on-premise."
"It has a drag-and-drop interface, so you don't need to know SQL or Java to construct a query on Splunk. The resolution time is about the same, but it took longer to discover the issue with ArcSight. Our previous solution took about an hour or more, but Splunk can do it within a few minutes or an hour at most."
"We saw the granularity that we could get from Splunk far exceeded what we already had. We had the ability to have our security team really focus on the platform and stay within the platform, but they could correlate with a variety of other stakeholders, and our stakeholders were growing."
"The level of robustness on offer is very good."
"Overall, it's a good tool."
"Splunk Enterprise Security offers excellent correlations, enhancements, and risk features that help my team."
"The solution's most valuable features are its ability to transact in the cloud and its ability to onboard data easily with minimum connectors."
"Splunk has facilitated the correlation of information security logs to look for incidents which could cause damage to the company's infrastructure, as well as financial losses from leaks."
 

Cons

"The stability of the solution is rated as three or four out of ten as we frequently encounter issues."
"Elastic Stack should be more simplified with ready-to-use widgets."
"AI-enablement would be a big improvement in Elastic Stack...If there is room for an ML model in Elastic Stack, then it would be good."
"Support could be improved. The error code is not helpful. We have to ask for it or pass it on to community forums."
"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."
"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."
"The tool's pricing can be improved."
"Splunk could have more built-in use case presets that customers can build on and customize."
"It will be helpful for customers if they can create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers."
"It needs documentation, and "how-to-do" information. It's complicated to build reports and views."
"We'd like to see a more seamless cloud-based integration."
"Splunk Enterprise Security can be improved with more AI in the commands and more help in the commands, as not all people know how to write code in SPL, and we need more help in this area."
"There are new services which are coming up. If Splunk can catch up with the speed of Amazon, and with the integration, instead of us waiting for another year or so, that would be good."
"One main change I would suggest is related to the incident board: when an incident is resolved, it should not appear on the incident board. It's just a rare occurrence that we open up the incident."
"Being able to have a one-stop shop where you have the alert, but then you can generate the case right there from Splunk Enterprise Security instead of having to pivot to another tool such as Mission Control. You do not have to keep bouncing between them, so if you could do it all in one place, that would be great. The new release is supposed to start getting in that direction."
 

Pricing and Cost Advice

"It depends on the specifics, but generally, Elastic is economical for certain use cases."
"The product is expensive."
"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."
"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."
"Ultimately, the pricing depends upon the capacity planning that the enterprise architect does."
"We are using the open-source community version of the product."
"Splunk is definitely not a cheap solution. It is an expensive product."
"I would highly recommend anyone evaluating this option to download the free trial which allows for the ingestion of 500MB of data per day in order to get a feel for what Splunk does at its core. It will get pricey once your ingestion rates start to sky rocket, but I would consider it expensive given the amount of information that it allows you to analyze and react on straight out-of-the-box."
"Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
"Be upfront about your needs and expectations. Splunk is great to work with."
"Splunk is priced higher than other solutions."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"The price is comparable."
"My experience with the solution's setup cost, pricing, and licensing was really good."
