"The machine learning and artificial intelligence on offer are great."
"It's easy to use. It's a very good product. It can easily ingest data from anywhere. It has an easily understandable language to perform actions."
"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."
"It has basic out-of-the-box integrations with multiple log sources."
"The product can integrate with any device."
"You can fine-tune the SOAR and you'll be charged only when your playbooks are triggered. That is the beauty of the solution because the SOAR is the costliest component in the market today... but with Sentinel it is upside-down: the SOAR is the lowest-hanging fruit. It's the least costly and it delivers more value to the customer."
"There are some very powerful features to Sentinel, such as the integration of various connectors. We have a lot of departments that use both IaaS and SaaS services, including M365 as well as Azure services. The ability to leverage connectors into these environments allows for large-scale data injection."
"Log aggregation and data connectors are the most valuable features."
"Easy to deploy and simple to use."
"The product has a good security posture."
"I like the search feature and the indexing. It's very fast and comprehensive."
"The most valuable feature is the custom dashboard feature."
"Out-of-the-box, it seems very powerful."
"It is very scalable."
"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."
"With good domain knowledge, one can build almost anything. If you throw in Alert Manager or an integration with ServiceNow. Then, you have your own SIEM"
"Microsoft Sentinel is relatively expensive, and its cost should be improved."
"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."
"The on-prem log sources still require a lot of development."
"While I appreciate the UI itself and the vast amount of information available on the platform, I'm finding the overall user experience to be frustrating due to frequent disconnections and the requirement to repeatedly re-authenticate."
"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."
"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."
"I would like to see more AI used in processes."
"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 Web Application Firewall will send you too much information because it's more dedicated to security than a normal firewall."
"Sometimes, there is latency in the logs."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
"I feel as though a major focus of upcoming releases should be set on Machine Learning, Predictive Analytics, and I would enjoy to see more security focused add-ons and apps developed by the vendor."
"My company could benefit from doing more Splunk training with Splunk consultants teaching us how to use it."
"Splunk can improve its third-party device application plugins."
"The solution could improve by giving more email details."
"There is a definite learning curve to starting out."
