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."
"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 part that was very unexpected was Sentinel's ability to integrate with Azure Lighthouse, which, as a managed services solution provider, gives us the ability to also manage our customers' Sentinel environments or Sentinel workspaces. It is a big plus for us. With its integration with Lighthouse, we get the ability to monitor multiple workspaces from one portal. A lot of the Microsoft Sentinel workbooks already integrate with that capability, and we save countless amounts of money by simply being able to almost immediately realize multitenant capabilities. That alone is a big plus for us."
"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."
"Sentinel enables us to ingest data from our entire ecosystem. In addition to integrating our Cisco ASA Firewall logs, we get our Palo Alto proxy logs and some on-premises data coming from our hardware devices... That is very important and is one way Sentinel is playing a wider role in our environment."
"It is quite efficient. It helps our clients in identifying their security issues and respond quickly. Our clients want to automate incident response and all those things."
"Sentinel uses Azure Logic Apps for automation, which is really powerful. This allows us to easily automate responses to incidents."
"The machine learning and artificial intelligence on offer are great."
"The search lookups are useful."
"The dashboards are the most valuable feature. We like the ability to drill in and see what queries are under the dashboard, build new visualizations, edit the querying, and see the reports."
"It has helped us look at modern technology, as well as penetrate our legacy systems, to see where the bottlenecks are."
"It helps streamline troubleshooting and log analysis."
"Splunk is quite flexible for our customers. Splunk does not filter from a specific lock, you can define it later."
"The varied prebuilt feature is the most valuable because it ensures that we have complete coverage over all of the key questions."
"It has virtual visualization, and other products do not."
"We have a more secure, robust environment, which keeps the harmful software out of the zone required."
"There is a wider thing called Jupyter Notebooks, which is around the automation side of things. It would be good if there are playbooks that you can utilize without having to have the developer experience to do it in-house. Microsoft could provide more playbooks or more Jupyter Notebooks around MITRE ATT&CK Framework."
"I think the number one area of improvement for Sentinel would be the cost."
"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."
"The playbook is a bit difficult and could be improved."
"Microsoft Defender has a built-in threat expert option that enables you to contact an expert. That feature isn't available in Sentinel because it's a huge product that integrates all the technologies. I would like Microsoft to add the threat expert option so we can contact them. There are a few other features, like threat assessment that the PG team is working on. I expect them to release this feature in the next quarter."
"Only one thing is missing: NDR is not available out-of-the-box. The competitive cloud-native SIEM providers have the NDR component. Currently, Sentinel needs NDR to be powered from either Corelight or some other NDR provider."
"In terms of features I would like to see in future releases, I'm interested in a few more use cases around automation. I do believe a lot of automation is available, and more is in progress, but that would be my area of interest."
"The interface could be more user-friendly. It''s a small improvement that they could make if they wanted to."
"Splunk Enterprise Security should provide a better and richer integration."
"Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported."
"The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
"Splunk Enterprise Security can be improved by including backup network detection and response and safe management to the paid platform."
"Deployment is not difficult but the lock sources and configurations can take time."
"Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this."
"The price has room for improvement."
"Its interface and usability can always be improved."
