Users recommend improvements to multi-tenancy, log ingestion, interface intuitiveness, and integration, with concerns over pricing and AI enhancement.
The licensing process needs improvement and clarification.
Improvements are needed in automated response capabilities.
Some inconsistencies exist between blades, which could be improved for a more seamless user and UI experience.
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.
 

Setup Cost

Includes four services and four products, which can help organizations a lot
We found that sometimes integrations work, but testing them can take some time. Sometimes, configurations take much longer than expected. We have a configuration in place that needs to be synchronized with another server. However, the servers are four hours apart, so this can cause delays. In general, I believe that the time it takes to configure and test a service should be shorter. Sometimes, it can take a couple of hours to test a single configuration setting. Other times, it is only ten or fifteen minutes, which is normal. However, sometimes, even immediate actions can be triggered by configuration changes, and some settings can take up to eight hours to complete. I believe that this time can be improved. Microsoft is making a lot of improvements to its services in a short period of time. This is a good thing, as it means that the services are constantly being updated and improved. However, it can be challenging for customers to keep up with the changes. For example, a customer may read about an update, understand it, and share it with their colleagues and boss. However, it may take days or weeks to test the update and get the necessary approvals. This can be especially challenging for large customers with many users or machines. In some cases, Microsoft may change a service before the customer has had a chance to implement the previous update. This can be frustrating for customers, as it means that they have to constantly learn new things and adjust their workflows. On the one hand, it is important for Microsoft to keep updating and improving its services. This helps to ensure that the services are meeting the customers' needs and that they are staying ahead of the competition. Microsoft should also be mindful of the challenges that these changes can create for customers. One way to address this challenge is to provide customers with more time to implement changes. Microsoft could also provide more information about upcoming changes so that customers can plan ahead. Ultimately, Microsoft needs to strike a balance between keeping its services up-to-date and providing customers with a smooth transition to new features.

Every rule enriched at triggering stage, easing the job of SOC analyst
It's a Big Data security analytics platform. Among the unique features is the fact that it has built-in UEBA and analytical capabilities. It allows you to use the out-of-the-box machine learning and AI capabilities, but it also allows you to bring your own AI/ML, by bringing in your own IPs and allowing the platform to accept them and run that on top of it. In addition, the SOAR component is a pay-per-use model. Compared to any other product, where customization is not available, 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. Other vendors charge heavily for the SOAR, 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. The SOAR engine also uniquely helps us to automate most of the incidents with automated enrichment and that cuts out the L1 analyst work. And combining M365 with Sentinel, if you want to call it integration, takes just a few clicks: "next, next finish." If it is all M365-native, it is a maximum of three or four steps and you'll be able to ingest all the logs into Sentinel. That is true even with AWS or GCP because most of the connectors are already available out-of-the-box. You just click, put in your subscription details, include your IAM, and you are finished. Within five to six steps, you can integrate AWS workloads and the logs can be ingested into Sentinel. When it comes to a third party specifically, such as log sources in a data center or on-premises, we need a log collector so that the logs can be forwarded to the Sentinel platform. And when it comes to servers or something where there is an agent for Windows or Linux, the agent can collect the logs and ship them to the Sentinel platform. I don't see any difficulties in integrating any of the log sources, even to the extent of collecting IoT log sources. Microsoft Defender for Cloud has multiple components such as Defender for Servers, Defender for PaaS, and Defender for databases. For customers in Azure, there are a lot of use cases specific to protecting workloads and PaaS and SaaS in Azure and beyond Azure, if a customer also has on-premises locations. There is EDR for Windows and Linux servers, and it even protects different kinds of containers. With Defender for Cloud, all these sources can be seamlessly integrated and you can then track the security incidents in Microsoft's XDR platform. That means you have one more workspace, under Azure, not Defender for Cloud, where you can see the security incidents. In addition, it can be integrated with Sentinel for EDR deep-dive analytics. It can also protect workloads in AWS. We have customers for whom we are protecting their AWS workloads. Even EKS, Elastic Kubernetes Service, on AWS can be integrated, as can the GKE (Google Kubernetes Engine). And with Defender for Cloud, security alert ingestion is free
