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.
"Sentinel uses Azure Logic Apps for automation, which is really powerful. This allows us to easily automate responses to incidents."
"The most valuable feature is the onboarding of the workloads. You can see all that has been onboarded in your account on the dashboards."
"The UI-based analytics are excellent."
"The machine learning and artificial intelligence on offer are great."
"The most valuable feature is the alert notifications, which are categorized by severity levels: informational, low, medium, and high."
"I've worked on most of the top SIEM solutions, and Sentinel has an edge in most areas. For example, it has built-in SOAR capabilities, allowing you to run playbooks automatically. Other vendors typically offer SOAR as a separate licensed solution or module, but you get it free with Sentinel. In-depth incident integration is available out of the box."
"The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities."
"It is able to connect to an ever-growing number of platforms and systems within the Microsoft ecosystem, such as Azure Active Directory and Microsoft 365 or Office 365, as well as to external services and systems that can be brought in and managed. We can manage on-premises infrastructure. We can manage not just the things that are running in Azure in the public cloud, but through Azure Arc and the hybrid capabilities, we can monitor on-premises servers and endpoints. We can monitor VMware infrastructure, for instance, running as part of a hybrid environment."
"It helps streamline troubleshooting and log analysis."
"The most valuable feature is the custom dashboard feature."
"The feature that we use the most is the correlation search engine within ES."
"The logs on the solution are excellent."
"Three features stand out for me: the SDK for writing Python, the customizable and adaptable diagnostic dashboard, and the optimizer for collecting data."
"Splunk incorporates a lot of elements that help to reduce security risks. For it to reach certain compliance, we need to have some security insight. Splunk is a very good SIEM, it’s a top solution, but the best feature is its cost of visibility. We have all the most important features to detect vulnerabilities or risks."
"This solution helps us increase our productivity."
"My favorite example of improving of organization is saving a $60k/mo in payroll fraud and $10k/mo in wasted API credits by using simple searches and clear reports."
"Sentinel can be used in two ways. With other tools like QRadar, I don't need to run queries. Using Sentinel requires users to learn KQL to run technical queries and check things. If they don't know KQL, they can't fully utilize the solution."
"We do have in-built or out-of-the-box metrics that are shown on the dashboard, but it doesn't give the kind of metrics that we need from our environment whereby we need to check the meantime to detect and meantime to resolve an incident. I have to do it manually. I have to pull all the logs or all the alerts that are fed into Sentinel over a certain period. We do this on a monthly basis, so I go into Microsoft Sentinel and pull all the alerts or incidents we closed over a period of thirty days."
"Sentinel's reporting is complex and can be more user-friendly."
"Microsoft Sentinel should provide an alternative query language to KQL for users who lack KQL expertise."
"They should just add more and more out-of-the-box connectors. It is quite a new product, and it has a lot of connectors, and even more would be good."
"They need to work with other security vendors. For example, we replaced our email gateway with Symantec, but we couldn't collect these logs with Azure Sentinel. Instead of collecting these logs with Azure Sentinel, we are collecting them on Qradar. We couldn't do it with Sentinel, which is a problem for us."
"One key area that can be improved is by building a strong integration with our XDR platform."
"We'd like to see more connectors."
"If it could be made available as a service, this would be much better than as a product."
"While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
"I find the graphical options really limited and you don't have enough control over how to display the data that you want to see."
"I would like to see more SIEM functionality and a better ticket tool."
"It can be tough to get a hold of somebody in technical support depending on the complexity of the issue."
"It's costly."
"We would like more integrations with other cloud products, not just AWS, e.g., Azure."
"It would be nice if they had a wizard to construct searches, including more complex searches that include math or statistics."
