We performed a comparison between Microsoft Sentinel and Splunk based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Microsoft Sentinel is the winner in this comparison. Compared to Splunk, it is easier to deploy, and has superior artificial intelligence. In addition, Microsoft Sentinel’s price is more attractive than Splunk’s.
"The ability of all these solutions to work together natively is essential. We have an Azure subscription, including Log Analytics. This feature automatically acts as one of the security baselines and detects recommendations because it also integrates with Defender. We can pull the sysadmin logs from Azure. It's all seamless and native."
"Another area where it is helping us is in creating a single dashboard for our environment. We can collect all the logs into a log analytics workset and run queries on top of it. We get all the results in the dashboard. Even a layman can understand this stuff. The way Microsoft presents it is really incredible."
"One of the most valuable features of Microsoft Sentinel is that it's cloud-based."
"We didn't have anything similar. So, it really provides value from the incidents and automation point of view. The overview of the security fabric is most valuable."
"The scalability is great. You can put unlimited logs in, as long as you can pay for it. There are commitment tiers, up to six terabytes per day, which is nowhere close to what any one of our customers is running."
"It's pretty powerful and its performance is pretty good."
"Native integration with Microsoft security products or other Microsoft software is also crucial. For example, we can integrate Sentinel with Office 365 with one click. Other integrations aren't as easy. Sometimes, we have to do it manually."
"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."
"It's better than IBM, in my opinion, because it's an independent entity."
"It's basically one of the best SIEM products on the market."
"We saw the granularity that we could get from Splunk far exceeded what we already had. We had the ability to have our security team really focus on the platform and stay within the platform, but they could correlate with a variety of other stakeholders, and our stakeholders were growing."
"The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
"The dashboard and reporting are very good... It provides very good visibility in a hybrid cloud environment, and you can build custom utilization APIs using Splunk."
"We have found all the features useful. However, the dashboarding and logging have been very helpful. Additionally, the log analysis does a great job."
"You can use it to gather syslog messages from anything."
"The following would be a challenge for any product in the market, but we have some in-house apps in our environment... our apps were built with different parameters and the APIs for them are not present in Sentinel. We are working with Microsoft to build those custom APIs that we require. That is currently in progress."
"We're satisfied with the comprehensiveness of the security protection. That said, we do have issues sometimes where there have been global outages and we need to raise a ticket with Microsoft."
"When we pass KPIs to the governance department, there's no option to provide rights to the data or dashboard to colleagues. We can use Power BI for this, but it isn't easy or convenient. They should just come up with a way to provide limited role-based access to auditing personnel"
"If you're looking to use canned queries, the interface could be a little more straightforward. It's not immediately intuitive regarding how you use it. You have to take a canned query and paste it into an operational box and then you hit a button... They could improve the ease of deploying these queries."
"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."
"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."
"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."
"It has been a challenge with Azure Sentinel to onboard the Syslog server from FortiGate. Azure Sentinel can work better on that shift between the Syslog server and a firewall."
"Writing queries is a bit complicated sometimes."
"Some of the search functions can be better. There has been a lot of talk at the conference about the update of SPL before each iteration. That will be a lot of help."
"The cluster environment should be improved. We have a cluster. In the Splunk cluster environment, in the case of heavy searches and heavy load, the Splunk cluster goes down, and we have to put it in the maintenance mode to get it back. We are not able to find the actual culprit for this issue. I know that cluster has RF and SF, but it has been down so many times. There should be something in Splunk to help users to find the reason and the solution for such issues."
"When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time."
"The glass table feature does not perform as expected."
"The UI could be better. This is applicable to Splunk in general. I know that a lot of people who get their hands on Splunk are hesitant to use it just because they find it overwhelming. There are a lot of options."
"I feel the solution to be too slow."
"Splunk could improve its default machine-learning models. Also, Splunk Enterprise's native threat intelligence isn't that good. I prefer a custom threat intelligence model."
