It is a stable solution, but they should make the user interface easier to understand
The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.

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

"I can have enterprise security, email security, next generation firewall security log, HIDS and NIDS logs, etc. all on the same dashboard. It makes it easy to pinpoint or correlate our server to this. I can find out if there is lateral movement. This is the biggest advantage of this solution."
"The product has a user-friendly interface and a valuable feature for threat intelligence integration."
"The software is scalable to whatever is required, and you can also put a lot of resources in the cloud."
"The most valuable feature is that we can create our own connectors for any application, and NetWitness provides the training and tools to do it."
"The product's initial setup phase was not at all difficult."
"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"NetWitness can be highly beneficial for incident detection and response."
"Offers a good wireless feature."
"We can easily configure things as required in relation to our use cases."
"The ability to analyze huge amounts of sales data and accurate prediction of sales forecasting is the most valuable feature."
"Compared to IBM QRadar, Splunk Enterprise Security offers faster alert resolution."
"There are a lot of third-party applications that can be installed."
"The ability to view all of these different logs, then drilling down into specific times or into specific data sources, has proved to be the greatest aspect in decreasing our troubleshooting overhead time."
"The ability to manipulate data in Splunk is unparalleled. Splunk’s powerful, flexible query language can morph difficult to understand log formats into usable data."
"It is very stable. We have not had any problems."
"I appreciate the integrations with the SOAR architectures and the expandability that can be used throughout the entire ecosystem of Splunk Enterprise Security."
 

Cons

"The solution should have more integration capabilities with different platforms."
"The product's licensing models are complex to understand. This particular area needs improvement."
"The threat detection capability and centralizing and upgrading capability need to be improved. The threat alert capability needs to be improved as well because there is some lag time at present. They need to work on their database search too."
"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"An area for improvement would be better automation and more inbuilt use cases."
"The tool's integration capability isn't so great."
"The initial setup is complex. There are other solutions that are easier to implement."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions. Whenever any hacking activity or any other threat factor occurred they used to provide the coverages very fast when comparing RSA NetWitness Logs and Packets. I heard the other three solutions, from a discussion with my team members who had experience in other solutions, they used to say that. Whenever any issues happened across the globe RSA NetWitness Logs and Packets are a little bit slow improving those detection mechanisms."
"The solution's case management system could be further improved to make it easier for analysts to manage cases."
"If it could be made available as a service, this would be much better than as a product."
"My organization does not completely utilize risk-based alerting in Splunk Enterprise Security as it's not fully mature."
"We find that the maintenance process could be a lot better."
"The AWS add-on is particularly problematic, with most inputs requiring manual writing due to lack of out-of-box functionality."
"Features related to content management must be improved."
"The solution has a high learning curve for users. It's a little complicated when you're trying to figure out all the features and what they do."
"Endpoint access is the only issue I can think to mention, even though the endpoint access we have with Cisco is fine."
 

Pricing and Cost Advice

"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"We have yearly licensing costs. The license fee can be based on the volume of EPS. Some organizations may have, as a gentlemanly gesture, 10,000 EPS and get a 3,000 EPS license but actually use 5,000 EPS."
"We are on an annual license for the use of the solution."
"Our license is for one year."
"The licenses are good but the cost is very expensive."
"This is a pricey solution; it's not cheap."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"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."
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
"The price of Splunk Enterprise Security is high."
"The pricing could be made more competitive."
"Splunk Enterprise Security's pricing is pretty competitive."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"The variables and the flexibility that Splunk provides are helpful, especially in a hybrid and multi-cloud environment."
