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.

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 most valuable features include the incident review and Dashboard Studio."
"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."
"Splunk's visualizations make it easy for users to understand the data."
"It provides a lot of analytics with the underlying AI engine, and it is a lot easier than other solutions. There are some products that do automated AI-based detection and drawing up charts, but for network monitoring and all of the monitoring aspects, it is quite a nice tool. It is very convenient for business users because they get more or less a lot of data readily available. If you're familiar with the Splunk query language, you can pretty much do whatever you want."
"The most valuable feature is that it's very good for log aggregation."
"The breadth of the data sources that Splunk can ingest data from is broad and deep and it does an exemplary job at handling structured data."
"Good for log collection and log management."
"It has reduced the time to resolution, time to investigate, and time to troubleshoot for debugging issues."

Cons

"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"We do have a Denial of Access happening."
"We are waiting for Dashboard Studio to mature a little bit more. There are some things that we are using with Classic Dashboards which have not yet made it to Dashboard Studio. We are waiting for that."
"Splunk could improve its default machine-learning models. Also, Splunk Enterprise's native threat intelligence isn't that good. I prefer a custom threat intelligence model."
"Adding custom visualization in Splunk has been improved over the years but can still be made better by integrating more and more JavaScript visualization sources."
"The configuration had a bit of a learning curve."
"Splunk could have more built-in use case presets that customers can build on and customize."
"I would like more assistance with use cases and help with teaching us how to use it once it's installed."
"When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time."
"Our two main complaints are about the difficulty of the initial setup and the licensing model."
