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

"I like the KQL query. It simplifies getting data from the table and seeing the logs. All you need to know are the table names. It's quite easy to build use cases by using KQL."
"Mainly, this is a cloud-native product. So, there are zero concerns about managing the whole infrastructure on-premises."
"The dashboard that allows me to view all the incidents is the most valuable feature."
"The SOAR playbooks are Sentinel's most valuable feature. It gives you a unified toolset for detecting, investigating, and responding to incidents. That's what clearly differentiates Sentinels from its competitors. It's cloud-native, offering end-to-end coverage with more than 120 connectors. All types of data logs can be poured into the system so analysis can happen. That end-to-end visibility gives it the advantage."
"The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities."
"The most valuable feature is the UEBA. It's very easy for a security operations analyst. It has a one-touch analysis where you can search for a particular entity, and you can get a complete overview of that entity or user."
"The solution offers a lot of data on events. It helps us create specific detection strategies."
"The main benefit is the ease of integration."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"Sometimes, we are observing large ingestion delays. We expect logs within 5 minutes, but it takes about 10 to 15 minutes."
"Not all information shows up in Sentinel. Sometimes there are items provided in 365 and if you looked in Sentinel you would not see them and therefore think they do not exist. There can be discrepancies between Microsoft tools."
"The troubleshooting has room for improvement."
"I would like Microsoft Sentinel to enhance its SOAR capabilities."
"I would like to see more AI used in processes."
"I would like Sentinel to have more out-of-the-box analytics rules. There are already more than 400 rules, but they could add more industry-specific ones. For example, you could have sets of out-of-the-box rules for banking, financial sector, insurance, automotive, etc., so it's easier for people to use it out of the box. Structuring the rules according to industry might help us."
"I would like to be able to monitor applications outside of the Azure Cloud."
"If I can use Sentinel offline at home and use it on a local network, it would be great. I'm not sure if I can use Sentinel offline versus the tools I have."
"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

"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's costly to maintain and renew."
"I am just paying for the log space with Azure Sentinel. It costs us about $2,000 a month. Most of the logs are free. We are only paying money for Azure Firewall logs because email logs or Azure AD logs are free to use for us."
"Pricing is pay-as-you-go with Sentinel, which is good because it all depends on the number of users and the number of devices to which you connect."
"From a cost point of view, it is not a cheap product. It's, like, an enterprise-level application. So if you compare it with a low-level application, it's expensive, but if you compare it with the same-level application, it's pretty much cost-effective, I think."
"For us, it is not expensive at this time, but if we start to collect all logs from our on-premise SIEM solutions, it will cost more than QRadar. If we calculate its cost over the next five or ten years, it will cost more than what we paid for QRadar."
"Sentinel is costly."
"The current licensing is based on the logs that are being ingested on the platform. Most of the SIEM solutions utilize that pricing model, but Microsoft should give us a customization option for controlling the kind of logs that we feed into Microsoft Sentinel. That will be much better. Otherwise, the pricing is a bit higher."
"It’s a single license platform."
