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

"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 biggest strength of Elastic Stack is its brilliant archiving capabilities."
"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."
"I think the ecosystem is well supported, and for logs, it was faster compared to our previous previous log management."
"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."
"It is an excellent tool for monitoring purposes."
"The only beneficial aspect of Elastic Stack is that it's open source."
"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."
"My overall experience with Splunk Enterprise Security in the energy sector has been overwhelmingly positive."
"The features I appreciate the most in Splunk Enterprise Security are the scheduled alerts and the search function."
"Without Splunk Enterprise Security, it would be difficult for us to manage and prioritize alerts. There's a potential to lose track of important notifications, and it's essential to our security that we do not miss anything. Splunk has improved our investigations because the reporting and dashboarding make things so much easier. We can provide weekly or monthly reports. I also like Splunk's ability to integrate."
"Aggregation searches have reduced time and difficulty of identifying trends and conditions which need to reviewed."
"Splunk's strongest suit is its user interface. We can integrate multiple solutions and adjust settings in the Splunk interface."
"The detailed log view is easy to read."
"The most valuable feature of Splunk is security information and event management (SIEM), and the solution is easy to use, has useful reports, and a good interface."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
 

Cons

"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."
"Agent deployment is a little tough in the on-premise version."
"Support could be improved. The error code is not helpful. We have to ask for it or pass it on to community forums."
"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 work on their dashboards and integration process."
"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."
"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."
"The Splunk platform is not unified. We have all of these different tools and they feel a bit disjointed."
"The solution's case management system could be further improved to make it easier for analysts to manage cases."
"It needs to improve the way to install third-party apps and enable installation without logging into splunk.com."
"It is a challenge to manage the environment in such a way, that one’s log, even with the bandwidth license, isn’t exceeded."
"You can run a script from an event, but it needs many clicks to run that integration, which could be made easier."
"Code understanding requirement is complicated for most users."
"The product could be cheaper."
"One area Splunk Enterprise Security fails to improve is the pricing aspect; while the initial pricing seems fine, the licensing cost can skyrocket over time, creating trauma for organizations."
 

Pricing and Cost Advice

"I rate the solution's pricing a six out of ten."
"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."
"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."
"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."
"The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"Splunk Enterprise Security is an expensive solution."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"It's definitely worth it."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"The pricing could be made more competitive."
