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.

ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

"The ability to ingest different log types from many different products in our environment is most valuable."
"The scalability of the solution is amazing because it can collect a lot of data and you can have your own structure to monitor this data."
"The features of Splunk Enterprise Security that I have found most valuable include the risk-based score and UBA/UEBA, user behavior analytics, or user and entity behavior analytics."
"Splunk would be my choice for the presentation layer because it comes with inbuilt reports and a dashboard that you can customize."

More Splunk Enterprise Security pros
 

Cons

"We do have a Denial of Access happening."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"​On the technical side, it would be nice to see aspects of the recent acquisition of Phantom make it into the core Splunk Enterprise, not just become a part of the premium Enterprise Security.​"
"Sometimes, the data does not match what we're looking for, or the tool contains incorrect data."
"I didn't face any major issues with Splunk Enterprise Security. There were only one or two issues related to the user account, but nothing major."
"The Enterprise Security app could be improved. We have had trouble with it working from the first day."
"The access and identity features could be improved. For example, let's say we have onboarded 65 logs. Now, we can identify the various processes, but we run into trouble when we're updating the processes for AWS CloudTrail, EDR, MDR, and XDR."
"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."
"The solution is expensive."
"I have concerns about the architecture as well since I can see it is not very well defined."

Pricing and Cost Advice

Information not available
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"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."
"Splunk Enterprise Security is expensive."
"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
"ROI is estimated at saving my team roughly 10 to 12 man hours per week in troubleshooting for our company as well as what our profits had been from our services of installing, configuring, and supporting other clients with the product."
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"The Splunk Enterprise Security license is expensive."
