Advanced query capabilities enhance monitoring effectiveness
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. Ideally, it should evolve into a full-stack observability tool, similar to AppDynamics or DynaTrace, which offers a solution that includes ISP provider, API monitoring, and infrastructure monitoring.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

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."
"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."
"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."
"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."
"I have experienced a return on investment from the use of the solution."
"It supports various integrations. It's open source and has excellent community support."
"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."
"Splunk works based on parsing log files."
"One key advantage of Splunk over competitors like IBM QRadar is its superior device integration capabilities."
"From a visibility perspective, the solution has significantly improved our organization by providing a single platform to visualize our entire IT landscape."
"Ease of correlation, creating correlation searches are easy and you can combine multiple sources with little effort"
"The most valuable feature of Splunk Enterprise Security is the threat intelligence integration because essentially having to go out and correlate all the data on our own becomes convoluted."
"The best features I've experienced over the past six years with Splunk Enterprise Security are the ability to create use cases and the flexibility to customize searches and use cases based on our specific requirements."
"I find it beneficial that Splunk Enterprise Security easily integrates with other tools. Due to its excellent API capabilities, it facilitates connections with various cybersecurity tools."
"The solution's most valuable feature is the aggregation of all the logs in one place, using enterprise securities built-in or ESCU use cases to find them."
 

Cons

"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."
"It should facilitate easier manual integration."
"The main issue related to Elastic Stack is in the area of its licensing."
"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."
"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 solution is expensive, particularly the training and certification. If customers want to increase their use of Elastic Stack, they should consider reducing the cost of certification and training."
"It lacks a clear NDR (Network Detection and Response) feature. If Elastic could enhance this aspect, it would significantly boost its capabilities."
"The upgrading process could be smoother."
"Most importantly, Splunk can be outrageously expensive. That is the problem with both Splunk and Sentinel. Their pricing literally explodes based on the amount of data you feed in."
"Splunk Enterprise Security is great but can have some frustration points. It can sometimes be slower to use."
"The area of concern revolves around the fact that Splunk is an expensive product."
"I would like additional features in different programming models with the support for writing queries in SQL or other languages, such as C#, Java, or some other type of query definitions."
"The solution's case management system could be further improved to make it easier for analysts to manage cases."
"Splunk could have more built-in use case presets that customers can build on and customize."
"The ingestion happens quickly, so you can run up the data costs if you use the default settings. It isn't a problem for government agencies in the Saudi market, but many of the corporations in India are small or medium-sized enterprises that cannot afford that kind of ingestion system."
 

Pricing and Cost Advice

"The pricing is reasonable."
"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."
"I rate the solution's pricing a six out of ten."
"We are using the open-source community version of the product."
"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."
"Splunk Enterprise Security is a bit expensive overall, but it provides good value."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"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."
"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."
"Splunk can be an expensive solution. It all depends on how we configure the alerts and the events from the endpoints. You can save some money if you do that correctly. If not, it becomes an expensive solution."
"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."
