Room For Improvement

Microsoft Sentinel users seek better integration, user-friendliness, documentation, AI capabilities, and customizable features with improved performance and pricing.

We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
Currently, we are happy to have a way in the middle with not so much cost, but it would be nice to have the ability to enhance the automation of workflows based on learned incidents.
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.
Although it enhances alert handling, it still has a journey to compete with Palo Alto SOAR and FortiSOAR.
