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."
"It can log more logs than other solutions. It's a good way to troubleshoot problems."
"Its usability is the best part. It is easy for our developers to use if they want to search their logs, etc."
"Our clients are easily able to modify and evolve their implementations."
"The ability to digest any information and then correlate it in accordance with what you need is valuable. The ability to connect to pretty much everything and bring the information in the same format is also valuable. On top of that, we can use their language in order to create and customize the dashboards, correlations, or analytics that we want to incorporate."
"Low barrier to start searching with the ability to normalize data on the fly."
"Search language is easy to understand and teach to new users."
"The community marketplace is useful; often, you do not need to rely on Splunk Enterprise Security support due to the wealth of online documentation available—Splunk docs are truly beneficial."
"Its dashboard is valuable. If you have a good knowledge of how to create a dashboard, you can create any dashboard related to cybersecurity. If fine-tuned, the alarms that are triggered for instant review are also very valuable and useful."

Cons

"We do have a Denial of Access happening."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"For on-premise, it's more about optimization. With such a heavy byte scale of data that we are operating on, the search for disparate data sometimes takes about a minute. This is understandable considering the amount of data that we are pumping into it. The only optimization that I recommend is better sharding, when it comes to Splunk, so that data retrieval can be faster."
"Splunk Enterprise Security should provide a better and richer integration."
"The product was designed for security and IT with business intelligence needs, such as PDF exporting, but this has not been the highest priority. While the functionality is there, it could be developed more."
"Splunk needs local technical support."
"It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive."
"I would like to see ability to master management. In terms of clustering, how it manages clustering needs improvement."
"Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power. When we execute heavy, resource-intensive queries over long periods, the performance dips."
"We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade."
