The summary above is based on 201 interviews we conducted recently with Splunk Enterprise Security and Microsoft Sentinel users. To access the review's full transcripts, download our report.
"Its inbuilt Kusto Query Language is a valuable feature. It provides the flexibility needed to leverage advanced data analytics rules and policies and enables us to easily navigate all our security events in a single view. It helps any user easily understand the data or any security lags in their data and applications."
"The most valuable features are its threat handling and detection. It's a powerful tool because it's based on machine learning and on the behavior of malware."
"The Identity Behavior tab furnishes us with the entire history linked to each IP or domain that has either accessed or attempted to access our system."
"Sentinel is a SIEM and SOAR tool, so its automation is the best feature; we can reduce human interaction, freeing up our human resources."
"The best functionality that you can get from Azure Sentinel is the SOAR capability. So, you can estimate any type of activity, such as when an alert was triggered or an incident was found."
"The solution offers a lot of data on events. It helps us create specific detection strategies."
"Sentinel also enables you to ingest data from your entire ecosystem and not just from the Microsoft ecosystem. It can receive data from third-party vendors' products such firewalls, network devices, and antivirus solutions. It's not only a Microsoft solution, it's for everything."
"Investigations are something really remarkable. We can drill down right to the raw logs by running different queries and getting those on the console itself."
"Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
"It provides a risk score for each object, device, or user. We can then take action if they are at a higher risk."
"The most valuable aspect of the solution is the dashboard. It's very intuitive."
"The indexing and data collection are valuable."
"The correlation searches are most valuable just because we are able to do things like RBA."
"Splunk's schema on demand is incredibly useful. I do not have to worry about what my users will need when we onboard their data."
"The solution is the market leader."
"It is quite extensible. It is a platform that we can build our use instead of each case instead of each case being limited or restricted to each capability. This is probably the best feature."
"Improvement-wise, I would like to see more integration with third-party solutions or old-school antivirus products that have some kind of logging capability. I wouldn't mind having that exposed within Sentinel. We do have situations where certain companies have bought licensing or have made an investment in a product, and that product will be there for the next two or three years. To be able to view information from those legacy products would be great. We can then better leverage the Sentinel solution and its capabilities."
"Everyone has their favorites. There is always room for improvement, and everybody will say, "I wish you could do this for me or that for me." It is a personal thing based on how you use the tool. I do not necessarily have those thoughts, and they are probably not really valuable because they are unique to the context of the user, but broadly, where it can continue to improve is by adding more connectors to more systems."
"Some of the data connectors are outdated, at least the ones that utilize Linux machines for log forwarding. I believe that Microsoft is already working on improving this."
"They're giving us the queries so we can plug them right into Sentinel. They need to have a streamlined process for updating them in the tool and knowing when things are updated and knowing when there are new detections available from Microsoft."
"The learning curve could be improved. I am still learning it. We were able to implement the basic features to get them up and running, but there are still so many things that I don't know about all its features. They have a lot of features that we have not been able to use or apply. If they could work on reducing the solution's learning curve, that would be good. While there is a training course held by Microsoft to learn more about this solution, there is a cost associated with it."
"If Azure Sentinel had the ability to ingest Azure services from different tenants into another tenant that was hosting Azure Sentinel, and not lose any metadata, that would be a huge benefit to a lot of companies."
"It could have a better API to be able to automate many things more extensively and get more extensive data and more expensive deployment possibilities. It can gain some points on the automation part and the integration part. The API is very limited, and I would like to see it extended a bit more."
"There is room for improvement in entity behavior and the integration site."
"I'd say I am happy with the technical support, not elated. They provide great support, but sometimes they don't have the answers that I need."
"Free-floating panels in the dashboards are like a glass table."
"I'd like to see more integration with more antivirus systems."
"Queries are not always as easy or straightforward as they might be, so it can be difficult to figure out what you need to look for."
"It needs more thoroughly tested releases. Every new big version (6, 7, etc.) has had so many bugs that it makes me wary of customers upgrading right away."
"When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time."
"This is not really a monitoring solution."
"Splunk does not provide any default threat intelligence like Microsoft Sentinel, but you can integrate any third-party threat intelligence with Splunk. By default, no threat intelligence suite is there, whereas, with IBM QRadar or Microsoft Sentinel, the default feature of threat intelligence is there. It is free. If Splunk can provide a default threat intelligence suite, it would be better."
