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

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We have no complaints about the features or functionality."
"The AI and ML of Azure Sentinel are valuable. We can use machine learning models at the tenant level and within Office 365 and Microsoft stack. We don't need to depend upon any other connectors. It automatically provisions the native Microsoft products."
"Microsoft Sentinel provides the capability to integrate different log sources. On top of having several data connectors in place, you can also do integration with a threat intelligence platform to enhance and enrich the data that's available. You can collect as many logs and build all the use cases."
"Sentinel also enables you to ingest data from your entire ecosystem and not just from the Microsoft ecosystem. It can receive data from third-party vendors' products such firewalls, network devices, and antivirus solutions. It's not only a Microsoft solution, it's for everything."
"Log aggregation and data connectors are the most valuable features."
"The most valuable feature is the onboarding of the workloads. You can see all that has been onboarded in your account on the dashboards."
"I believe one of the main advantages is Microsoft Sentinel's seamless integration with other Microsoft products."
"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."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"The solution could improve the playbooks."
"If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable."
"From a client perspective, they'd like to see more cost savings."
"They only classify alerts into three categories: high, medium, and low. So, from the user's point of view, having another critical category would be awesome."
"I think the number one area of improvement for Sentinel would be the cost."
"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."
"Everyone has their favorites. There is always room for improvement, and everybody will say, "I wish you could do this for me or that for me." It is a personal thing based on how you use the tool. I do not necessarily have those thoughts, and they are probably not really valuable because they are unique to the context of the user, but broadly, where it can continue to improve is by adding more connectors to more systems."
"One key area that can be improved is by building a strong integration with our XDR platform."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
"It is certainly the most expensive solution. The cost is very high. We need to do an assessment using the one-month trial so that we can study the cost side. Before implementing it, we must do a careful calculation."
"Microsoft Sentinel is included in our E5 license."
"Sentinel is costly compared to other solutions, but it's fair. SIEM solutions like CrowdStrike charge based on daily log volume. They generally process a set number of logs for free before they start charging. Microsoft's pricing is clearer. It's free under five gigabytes. Some of these logs we ingest have a cost, so they don't hide it. I believe the tenant pays the price, and Microsoft helps create awareness of the cost."
"It's costly to maintain and renew."
"The pricing isn't very high. It depends on the number of logs you have. If you're expecting to ingest 50 to 60G in a day, but you're only ingesting 20 to 25G per day at first and you have a good team to analyze the logs, then you can segregate the ingestion at under 15G."
"The pricing is fair... With a traditional SIEM, you pay a lump sum for licenses. But with Sentinel, it's pay-as-you-go according to the amount of data you inject."
"The combination of the ease of accessibility and the free cost of the service is great. But we buy storage based on our events per second and on how many sources are integrated into the solution."
"It’s a single license platform."
