    Dannie Combs - PeerSpot reviewer
    The alert fatigue and false positive rates have just plummeted, which is really exciting.
    empow has a few areas of improvement as with any other technology, such as continuing to drive innovation in the dashboard. While we've been extremely impressed with the dashboard's ease of use, flexibility, ability to drill down deeply, and focus very intently on an area of interest, there will always be opportunities to be more innovative and open it up to a wider audience than just the operations group, for example. With reporting, there is always a desire to have custom reporting for every client of empow. Relative to keeping up with the sheer pace of cloud-native technologies, it should provide more options for clients to deploy their technologies in unique ways. This is an area that I recommend that they maintain focus.

    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

    "As a result of the automation, we are able to manage SIEM with a small security team. I'm in a unique position where we have been growing the security organization quite rapidly over the last three and a half years. But, as a direct result of the empow transition and legacy collection of tools towards the empow platform, we've been able to keep that head count flat. We've been able to redirect a lot of the security team's time away from the wash, rinse, repeat activities of responding to alarms where we have a high degree of confidence that they will be false positives, adjusting the rules accordingly. This can be a bit frustrating for the analyst when they have to spend hours a day dealing with these types of probable false positives. So, it has helped not only us keep our headcount flat relative to the resources necessary to provide the assurances that our executives expect of us for monitoring, but allows our analyst team to spend the majority of their time doing what they love. They are spending their time meaningfully with a higher degree of confidence and enjoying getting into the incident response type activity."
    "Now with Splunk Enterprise Security, we have everything in one place—the notables are created automatically, but they can also create their own notables based on the investigation, which improved and reduced about 50% of the manual work that was done before versus what we are doing now."
    "The data analysis part is good in Splunk, which is something that I like the most. It is also quite easy to use. Its dashboards, visualizations, and analytics are good."
    "We can extract the metrics we want on the dashboards. We are able to react to the incidents."
    "UBA, User Behavior Analytics, is a key feature."
    "Scalability-wise, the tool is awesome since you can add or reduce your resources in an easy way."
    "Visualizations are the best way to understand deviation techniques from the norm."
    "It has been really good at consolidating a lot of data from different sources. It's really good at generating summaries."
    "The technical support is among the best in the market."

    Cons

    "Relative to keeping up with the sheer pace of cloud-native technologies, it should provide more options for clients to deploy their technologies in unique ways. This is an area that I recommend that they maintain focus."
    "The GUI can be improved to include some of the capabilities that other BI solutions have."
    "While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
    "On-premises scaling of the solution is a bit more limited than it is on the cloud."
    "The product must improve insider threat detection."
    "It is a challenge to manage the environment in such a way, that one’s log, even with the bandwidth license, isn’t exceeded."
    "The threat detection system has room for improvement."
    "I would definitely improve the risk-based alerts in Splunk Enterprise Security, helping SOC analysts to get to the drill-down searches."
    "Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue."

    Pricing and Cost Advice

    "With a higher degree of fidelity in the alarms, we were able to avoid adding additional resources to our teams. We take into account the cost of security resources in the market and the significantly higher fidelity from the alarms that are being generated. This drove down our costs with our MSSP. It drove down my cost for human capital internally. It drove down our need to have multiple resources supporting the underlying infrastructure and health and maintenance of empow as a platform from several resources down to one. Therefore, human capital costs were significantly reduced. Our operating expenses were significantly reduced. Our capital costs were significantly reduced while tripling our capacity and our run rate reduced. It was almost a "too good to be true" situation. Fortunately, for us, it worked out very nicely."
    "I don't have to put up with any longer with these hypercomplex licensing agreements. Every time I want to add some additional reporting as a compliance centric or regulatory specific, e.g., GDPR, PCI, or Sarbanes-Oxley, many providers would have an additional license for this, which felt a bit ridiculous to me. With the simplified licensing architecture, there were no hidden "gotchas" down the road with empow. Something I have experienced with other providers that I've worked with in the past."
    "It can be tough to determine if you are getting all of the value out of your investment at times."
    "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."
    "Pricing is probably its weakest spot. As compared to some competitors, Splunk is really expensive."
    "While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
    "Pricing can be a limiting factor. You have to continuously tune what you are bringing in and make sure what you bring in is of value."
    "Splunk is expensive based on our current requirements, but it's obviously worth what we pay."
    "It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits."
    "The Splunk Enterprise Security license is expensive."
