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 incident review in Splunk Enterprise Security seems to be the most helpful feature."
"It has helped us look at modern technology, as well as penetrate our legacy systems, to see where the bottlenecks are."
"The indexing and data collection are valuable."
"The solution's newly developed dashboard is pretty amazing."
"The product is good, it satisfies our customers."
"The compatibility with the add-ons helps us add more data in the same compatible format and use data models to elaborate and make it faster."

"The initial setup is really straightforward. It's one of the easiest installations."

Cons

"We do have a Denial of Access happening."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"Spam has different plugins but by default, the logs are not organized, it shows that there are roll-ups that are out of the box. I saw many plugins that can help improve or extend Splunk's functionality but I haven't tried any of them."
"This is not really a monitoring solution."
"I would like Splunk to add more integration. QRadar has many indications with more products than Splunk."
"There are limitations with Splunk not detecting all user activity, especially on mainframes and network devices."
"Its performance can be better. Sometimes, it takes longer when we do queries."
"There are new services which are coming up. If Splunk can catch up with the speed of Amazon, and with the integration, instead of us waiting for another year or so, that would be good."
"I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging."
"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."

Pricing and Cost Advice

Information not available
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"The solution is a little expensive."
"Pricing and licensing are quite high compared to other tools or SIEM tools, but the features justify it."
"Licensing is a yearly, one-time cost."
"I am not personally involved with the pricing of the solution."
"The pricing can be better. We are already considering Elastic because Splunk is too expensive. You have to pay based on per-day ingestion. There should be a more flexible model for the use cases where one day you have a huge amount, and on other days, it is quite less."
"Splunk is a bit pricier, but the benefits and ROI are huge."
"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."
