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 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 a very scalable solution...I didn't face any problem with this scalability part of the solution since we only have a few pieces of equipment in our company."
"The machine learning capabilities are valuable."
"I think the ecosystem is well supported, and for logs, it was faster compared to our previous previous log management."
"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 scripting model in Elastic Stack allows me to query logs and then put the data into Grafana."
"Elastic Stack has made a positive impact as we can now see our logs."
"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."
"Splunk's visualizations make it easy for users to understand the data."
"Three features stand out for me: the SDK for writing Python, the customizable and adaptable diagnostic dashboard, and the optimizer for collecting data."
"I would strongly recommend this product, as it would be very beneficial for service operations and management."
"Splunk UBA is useful for fraud detection and for detection of APTs, advanced persistent threats."
"The end-to-end visibility into our environment that Splunk provides is impressive. We just need to use it better."
"Visualizations are the best way to understand deviation techniques from the norm."
"The features I find most valuable in Splunk Enterprise Security are Incident Review, Security Essentials, Asset and Identity Management, and Machine Learning Toolkit."
"The most valuable feature is the DSS, also known as SPL, because it allows users to script advanced queries with limited knowledge."
 

Cons

"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."
"It lacks a clear NDR (Network Detection and Response) feature. If Elastic could enhance this aspect, it would significantly boost its capabilities."
"Support could be improved. The error code is not helpful. We have to ask for it or pass it on to community forums."
"The tool's pricing can be improved."
"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."
"In terms of training. I find that some things about Splunk aren't well-explained. I see features and then go to the website but don't find good explanations."
"Integrating tools and creating use cases could be easier. It's hard for a junior security engineer with only a couple of years of experience to write use cases. They can do it, but it's much easier in a solution like IBM QRadar. Setting conditions is like a multiple-choice type of thing. It's a more user-friendly process."
"Could be more user friendly."
"We'd like to have the number of devices covered under the license to be increased."
"Free-floating panels in the dashboards are like a glass table. It needs more formatting control without having to be an admin."
"Make it easier to include roles and user controls, as it is horrible now."
"Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
 

Pricing and Cost Advice

"I used the open-source version of Elastic Stack, because of which I did not have to pay anything."
"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."
"I rate the solution's pricing a six out of ten."
"It depends on the specifics, but generally, Elastic is economical for certain use cases."
"We are using the open-source community version of the product."
"The product is expensive."
"The pricing is reasonable."
"Splunk can be expensive, as its licensing is based on the daily data ingestion volume."
"It is a bit costly."
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"The cost is on the high end, which makes it difficult for some organizations to use."
"Pricing is pretty fair."
"Splunk Enterprise Security incurs a significant cost because of the amount of data we send, but we are fine with the value we're getting for that price."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"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."
