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.
"It is easy to implement (turn on) - does need a skilled analyst to develop queries and playbooks."
"The in-built SOAR of Sentinel is valuable. Kusto Query Language is also valuable for the ease of writing queries and ease of getting insights from the logs. Schedule-based queries within Sentinel are also valuable. I found these three features most useful for my projects."
"The solution has features that helped improve the security posture of our clients. It provides the ability to correlate a large variety of log sources very cost-effectively, especially for Microsoft sources."
"The most valuable feature is the UEBA. It's very easy for a security operations analyst. It has a one-touch analysis where you can search for a particular entity, and you can get a complete overview of that entity or user."
"The analytics has a lot of advantages because there are 300 default use cases for rules and we can modify them per our environment. We can create other rules as well. Analytics is a useful feature."
"The AI capability is one of the main features of the solution because I believe that in the market, there are few solutions that are providing security solutions based on AI and machine learning."
"I like the ability to run custom KQL queries. I don't know if that feature is specific to Sentinel. As far as I know, they are using technology built into Azure's Log Analytics app. Sentinel integrates with that, and we use this functionality heavily."
"Sentinel is a Microsoft product, so they provide very robust use cases and analytic groups, which are very beneficial for the security team. I also like the ability to integrate data sources into the software for on-premise and cloud-based solutions."
"The UI of Splunk makes it easier for our analysts to move around and see what they need to see."
"The most valuable feature is the incident dashboard, and the extensive use of correlation searches, which isn't available with a standard Splunk search package. This feature is important to me because it enables SOC analysts to do their job more efficiently and be able to investigate or mediate incidents at a faster pace."
"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."
"It's very flexible. If you look from the cloud implementation it is there. Reports are made quickly. Unlike other tools, it caters to all kinds of technical information on the front very easily. There's no need to put in any technical information. You can pull on the reports very easily, take action, and notify stakeholders."
"Splunk has machine learning which is a valuable feature."
"It is very simple to tweak or write a small piece of glue code to go ahead and create a new dashboard for a business unit to make near real-time decisions to focus more on other geographies when launching the product."
"The scalability is good."
"The most valuable feature is the custom dashboard feature."
"Azure Sentinel will be directly competing with tools such as Splunk or Qradar. These are very established kinds of a product that have been around for the last seven, eight years or more."
"Add more out-of-the-box connectors with other SaaS platforms/applications."
"Its documentation is not so simple. It is easy for somebody who is Microsoft certified or more closely attached to Microsoft solutions. It is not easy for those who are working on open-source platforms. There isn't a central point where everything is documented, and there is no specific training or certification."
"They should integrate it with many other software-as-a-service providers and make connectors available so that you don't have to do any sort of log normalization."
"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."
"The product can be improved by reducing the cost to use AI machine learning."
"Sentinel could improve its ticketing and management. A few customers I have worked with liked to take the data created in Sentinel. You can make some basic efforts around that, but the customers wanted to push it to a third-party system so they could set up a proper ticketing management system, like ServiceNow, Jira, etc."
"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."
"DMC should be a little more intuitive with better dashboarding. Seeing the cause of data flow can be tough to track down."
"The product is relatively expensive."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
"There is a definite learning curve to starting out."
"I would like to see more SIEM functionality and a better ticket tool."
"The upgrading process could be smoother."
"Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs."
"In the next releases, I would like to see more pricing flexibility."
