Integrated auditing has strengthened data retention and improved incident investigations
I have seen areas for improvement, specifically in Microsoft Purview Audit or in general about Microsoft. I have had a situation with documentation. I had a customer who wanted to create alerts and they had Microsoft 365 Business Premium. In the documentation, it was noted that this license is enough for creating alerts. When we tried to make them, we noticed they cannot do it with Microsoft 365 E3 because the customer had limited features to manage alerts. The customer had to buy E3. We created Microsoft support requests, and they confirmed that the documentation displayed not the real situation and they have been going to update documentation. The same situation occurred now with implementing Microsoft Purview Audit in the last autumn. eDiscovery was combined with search and content search, and the documentation was not clear at the beginning. It was a little difficult to describe to customers that now it is a part of eDiscovery. Content search is a very simple functionality, while eDiscovery is a little difficult. I am not entirely sure why Microsoft is going in the way of combining these services because they are the same. However, for a customer who has never seen these services, it is difficult to understand quickly. The same situation occurs with litigation holds and some other holds. For any mail, I am trying to keep data. For example, emails are held for a year or two years, ten years, it does not matter. It is difficult to understand where to find this data and where these emails are being held. I need to use eDiscovery to find out all deleted data that was kept somewhere in some hidden folders of the mailbox. Regular customers and regular administrators know that on-premises Exchange, for example, allows them to find the data in some repository and review the list of kept data. However, with this hold, we do not have any functionality to review the list of kept data. It is difficult to understand for customers how to work with this. I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails. This is difficult.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The main Microsoft feature is that it offers common integration of services, of data, of identity, meaning user accounts, user access, and privileged access."
"We're easily saving at least one hour per day using this solution."
"The overall user experience with Microsoft Purview Audit is of higher quality than when it was branded as Compliance Center, and Microsoft consistently updates and evolves functionalities and the overall experience."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"The visibility is amazing with easy dashboard creation."
"Integration with the cloud is pretty important and good for us. We found the integration with a lot of tools, not all tools yet, valuable. It does make the transfer of data, log files, and other things easier for us."
"It helps us to detect viruses and security events from our network."
"The stability and reliability of Splunk Enterprise Security is outstanding. It's a software and product that anybody can really pick up and use."

"The features of Splunk Enterprise Security that I find most valuable are the correlation and correlation data."
"The solution helped reduce our alert volume."
"Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
 

Cons

"We do have a Denial of Access happening."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
"I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"The product's price may be an area of concern where improvements are required."
"We'd like to see a more seamless cloud-based integration."
"Splunk could enhance its services by providing more comprehensive professional assistance aimed at optimizing our investment."
"The main issue that I have with it is that the field transformations sometimes overlap with those in Splunk Enterprise, and then you get permissions issues that lead to troubles."
"DMC should be a little more intuitive with better dashboarding. Seeing the cause of data flow can be tough to track down."
"The configuration had a bit of a learning curve."
"Splunk is such a large product. Allowing it to be more easily used by people who have not had a lot of training on it would be an improvement."
"Visualizations can improve. There are some performance and stability issues with the visualization layer."
 

Pricing and Cost Advice

Information not available
"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
"It's a little bit expensive for a small to medium enterprise."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"Pricing and licensing is quite expensive. But for the value the product provides, it seems at par in the market."
"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."
"The pricing of Splunk Enterprise Security is somewhat high, but comparing it with its benefits, it's acceptable. It depends on the type of business."
"Splunk Enterprise Security's pricing is competitive."
