Enables us to create a user in the cloud and give them access to resources through a single workflow
The PAM for Active Directory is good. ActiveOps is quite useful as a feature. The One Identity active role enables us to create a user in the cloud and give them access to resources through a single workflow. We can create rules-based access. It helps us control audit management and IT access management. We can decide what people can access and detect job functions. It enables zero trust security with hybrid AD, find delegation, and role-based access control. It provides all certificates and provides secure authentication, call-based access control, et cetera. It's really important for my critical applications. We can see who's using what, whether they are authorized, and other information to decide what access to offer. With the active role console, I can find out the obvious issues and also perform a decent setup. The One Identity active roles enable us to reduce password reset times. We can handle tasks in a matter of a minute. It simplifies AD and Azure AD management, efficiency, and security overall. The password manager is very secure and is a self-service password manager solution. It is considerably decreasing my help desk tasks. Our engineering users can reset forgotten passwords, and it can implement a stronger password. The management around access to enterprise resources keeps my data and systems secure. We're easily saving at least one hour per day using this solution. The migration from AD to Azure AD is very easy. There are simple configurations, and the migration goes rather smoothly. We use the solution support for SaaS apps through Cloud Delivered SCIM connectors. There are controls that can be configured and we can add and set permissions easily.

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

"We're easily saving at least one hour per day using this solution."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"The correlation searches (properly configured) populate the Incident Management dashboard and provide me a quick birds-eye view of my most important concerns."
"The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
"Aggregation searches have reduced time and difficulty of identifying trends and conditions which need to reviewed."
"The feature I appreciate the most about Splunk Enterprise Security is the CIM data model, which allows users to bring in data from different technologies, such as firewalls, endpoints, and perimeter DMZs, enabling every device to pump data into Splunk Enterprise Security, with the data model normalizing all the data and placing it in a common plane."
"Splunk RBA or risk-based alerting definitely made our lives a lot easier; we went from hundreds of alerts having to be triaged a day, that generally could be false positives or just noise, and bubble them into one overall alert that we can look at on a per-day basis and see what's rising to the top and respond faster, have a higher rate of true positives and find evil a lot quicker."
"Being able to aggregate detection and alerts from various sources is valuable. Like everyone else, we have a wide range of tools in our shop. We are able to stop at one spot and look at all the data. All the data is able to come through, and we can then jump from source to source or index to index. We can dig deep whenever we need to and get a good high-level understanding."
"Splunk Enterprise Security is amazing."
"I like Splunk's data aggregation and search capabilities."

Cons

"We do have a Denial of Access happening."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"Writing queries is a bit complicated sometimes."
"The GUI, now called Mission Control, which serves as issue management or ticket management, falls below what would be considered industry standards."
"The integration with all our tool sets felt like we were reinventing the wheel, which was a pain point for us."
"There were only one or two issues related to the user account, but nothing major."
"To improve Splunk Enterprise Security, I suggest incorporating more AI features for faster remediation and enhanced responses, allowing users to build more correlation searches quickly."
"It would be nice if they had a wizard to construct searches, including more complex searches that include math or statistics."
"Customizing our commands should be simpler. Creating custom commands in Splunk requires a long, complex process. For example, we have a command to add all the column data, but we don't have a command to get the average of the column data at the end. It would be useful to have a blank at the end to create our commands and leave the rest to others."
"Data retention can be better. If we want to look at the data for five months or six months, that is not available to us."
More Splunk Enterprise Security cons
 

Pricing and Cost Advice

Information not available
"It is a bit costly."
"Splunk ES is quite expensive compared to some products on the market."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"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."
"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."
"The price of Splunk is reasonable."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
