Threat detection and response capabilities enhance investigation processes
My security team has been using Microsoft Sentinel for around two years. We also have Bastion and SolarWinds as part of our monitoring tools. We use a three-way tool, alongside Microsoft Sentinel, in our environment The most valuable features for us include threat collection, threat detection,…

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 log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities."
"There are a lot of things you can explore as a user. You can even go and actively hunt for threats. You can go on the offensive rather than on the defensive."
"Microsoft Sentinel enables you to ingest data from the entire ecosystem and that connection of data helps you to monitor critical resources and to know what's happening in the environment."
"We’ve got process improvement that's happened across multiple different fronts within the organization, within our IT organization based on this tool being in place."
"The initial setup is very simple and straightforward."
"It's pretty powerful and its performance is pretty good."
"Sentinel has reduced the work involved in the event investigation by quite a lot."
"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

"Their support can be challenging at times, particularly around unique experiences or circumstances with Microsoft Sentinel."
"The playbook is a bit difficult and could be improved."
"They should just add more and more out-of-the-box connectors. It is quite a new product, and it has a lot of connectors, and even more would be good."
"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."
"Some of the data connectors are outdated, at least the ones that utilize Linux machines for log forwarding. I believe that Microsoft is already working on improving this."
"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."
"There is room for improvement in terms of integrations."
"Microsoft Sentinel's search efficiency can be improved, especially for queries spanning large datasets or long timeframes like 90 days compared to competitors like Splunk."
"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

"Cost-wise, Sentinel is based on the volume of information being ingested, so it can be quite pricey. The ability to use strategies to control what data is being ingested is important."
"It is a consumption-based license model. bands at 100, 200, 400 GB per day etc. Azure Sentinel Pricing | Microsoft Azure"
"Good monthly operational cost model for the detection and response outcomes delivered, M365 logs don't count toward the limits which is a good benefit."
"It comes with a Microsoft subscription which the customer has, so they don't have to invest somewhere else."
"The pricing is based on how much you ingest, so it's pretty straightforward. There are no tiers, and you pay for what you use unlike with other types of SIEM solutions that are usually based on tiers."
"From a cost perspective, Microsoft Sentinel is quite costly."
"It is consumption-based pricing. It is an affordable solution."
"I'm not happy with the pricing on the integration with Defender for Endpoint. Defender for Endpoint is log-rich. There is a lot of information coming through, and it is needed information. The price point at which you ingest those logs has made a lot of my customers make the decision to leave that within the Defender stack."
"It’s a single license platform."
