Information Technology Security and Infrastructure Expert at a government with 201-500 employees
Helps to deal with potential attacks and is available at a reasonable price
My company has had many benefits from the use of the product in the last eight years. The tool has streamlined our company's incident response process since it serves as a log repository, which allows us to correlate events and access different technology stacks. In our company, we were able to actually find some potential attacks, so it has been very helpful. The tool's integration capability isn't so great. In my company, we managed to integrate it with our Microsoft Azure Subscription, after which we managed to integrate it with other tools. You will face a lot of difficulties if you want to integrate it with your database monitoring tool, PAM solutions, or IAM products. The product has done well overall for my company's teams to deal with their workflow efficiency. I would not recommend the product to others. I rate the tool a seven 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

"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"RSA NetWitness is a SIEM and real-time network traffic solution that collects logs and packets, applies a set of alerting, reporting, and analysis rules on them, and thus provides the enterprise with full visibility of the networks and activities of the systems."
"This solution has a very good dashboard with a separate tab for incidents and alerts."
"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."
"It's fully scalable. There is no limit. Of course, the license limits per day the number of terabytes. In my opinion, it's very flexible."
"Setting up NetWitness is straightforward. There are multiple connectors, including standard and specialized connectors. One purpose of the connectors is the enhanced capability integrate the custom applications. NetWitness comes with E6 appliances and application images that we use for the initial configurations and for the OS stack information. From there, you can consider the correlation rules, integrate the different log sources, and easily create correlation rules and backlog reports."
"Once it is deployed and you are used to it, you can do whatever you want."
"The most valuable feature is the hunting ability to work in a CERT."
"It scales better in the cloud than on-premise."
"The community marketplace is useful; often, you do not need to rely on Splunk Enterprise Security support due to the wealth of online documentation available—Splunk docs are truly beneficial."
"Since Splunk is a platform for data, we can ingest and correlate data from virtually any type of system."
"Splunk simplifies real-time problem identification and resolution by seamlessly integrating existing customer and vendor systems."
"They provide excellent predefined user cases."
"The ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"The indexing and data collection are valuable."
"I would assess the stability and reliability of Splunk Enterprise Security as typically very good, with minimal downtime or crashes."
 

Cons

"If we have the ability to run a dynamic analysis through malware in the same suite, it would be great to have a sandbox solution to analyze malware through dynamic analysis."
"The user interface is a little bit difficult for new users and it needs to be improved."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"One thing to be improved in NetWitness is the capability to correlate event logs in a general sense."
"The product's licensing models are complex to understand. This particular area needs improvement."
"The initial setup was complex because it takes a lot of time to complete the implementation."
"I believe they could improve their support, there are often delays."
"Security needs improvement. We would still like to know how the traffic is entering the organization."
"The product is relatively expensive."
"The only downside is the pricing."
"This is not really a monitoring solution."
"The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
"One of the biggest challenges is its licensing cost, especially for organizations that ingest large volumes of data."
"In my personal opinion, it is too complicated. Installing forwarders and trying to get an overview of a network topology with Splunk Enterprise Security is challenging."
"Over time I will have more requirements and I can foresee the solution could improve the search algorithm to run and output the data faster."
 

Pricing and Cost Advice

"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"Our license is for one year."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"It is cheap."
"The licenses are good but the cost is very expensive."
"This is a pricey solution; it's not cheap."
"The product price was reasonable for my region and the market."
"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"Our ROI is high."
"I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more."
"Splunk Enterprise Security is affordable."
"The price of this solution is expensive. However, it has great features. If you want a great solution you need to pay a price matching the features."
