MOTASHIM Al Razi - PeerSpot reviewer
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.
Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the ability to write rules and triggers for network communication, and then being able to investigate based on that."
"It gives the ability to investigate into network traffic in the Net and the organization what we couldn't do before."
"Incident management is its most valuable feature."
"NetWitness can be highly beneficial for incident detection and response."
"What we are mainly using are the RSA concentrator, RSA Decoder, Archiver, Broker, and Log Decoder."
"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 most valuable feature of RSA NetWitness Logs and Packets are the alerts and correlations tools."
"The product's initial setup phase was not at all difficult."
"The stability of Splunk Enterprise Security is very impressive; it is a very stable product."
"The security part is useful as it helps secure the entire environment."
"We can automatically suspend or terminate suspicious sessions."
"The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems."
"It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective."
"This solution helps us increase our productivity."
"I appreciate the integrations with the SOAR architectures and the expandability that can be used throughout the entire ecosystem of Splunk Enterprise Security."
"The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me."
 

Cons

"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 product's licensing models are complex to understand. This particular area needs improvement."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"Technical support could be improved."
"The user interface is a little bit difficult for new users and it needs to be improved."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"The implementation needs assistance."
"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
"We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."
"The setup time is quite long."
"The Enterprise Security app could be improved. We have had trouble with it working from the first day."
"I would like more assistance with use cases and help with teaching us how to use it once it's installed."
"It would be great if I could have a certain dialogue box in Splunk that uses innovative AI tools like ChatGPT, which are available now in the tech department."
"Make it easier to include roles and user controls, as it is horrible now."
"The licensing price is high and has room for improvement."
"My biggest struggle with Splunk in general is memorizing all the commands. If I want to know which users have logged in between certain hours, I cannot write that query out. It would be helpful to have AI so that I can explain in simple terms what I want and then the search gives that back to me. I am waiting for that."
 

Pricing and Cost Advice

"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"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."
"This is a pricey solution; it's not cheap."
"The licenses are good but the cost is very expensive."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"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."
"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."
"Splunk is definitely not a cheap solution. It is an expensive product."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"It's definitely worth it."
"It's more expensive than the other tools, but it's worth it. Every penny is worth it."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"The pricing of Splunk Enterprise Security is somewhat high, but comparing it with its benefits, it's acceptable. It depends on the type of business."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
