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

"One of the most valuable features is that it creates a kind of a single pane of glass for organizations that already use Microsoft software. So, when they have things like Microsoft 365, it is very easy for them to kind of plug in or enroll those endpoints into the Azure Sentinel service."
"Sentinel's most important feature is the ability to centralize all the logs in one place. There's no need to search multiple systems for information."
"The most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."
"The UI-based analytics are excellent."
"The ability of all these solutions to work together natively is essential. We have an Azure subscription, including Log Analytics. This feature automatically acts as one of the security baselines and detects recommendations because it also integrates with Defender. We can pull the sysadmin logs from Azure. It's all seamless and native."
"The main benefit is the ease of integration."
"One of the most valuable features of Microsoft Sentinel is that it's cloud-based."
"It is quite efficient. It helps our clients in identifying their security issues and respond quickly. Our clients want to automate incident response and all those things."
"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 playbook is a bit difficult and could be improved."
"I would like Microsoft Sentinel to enhance its SOAR capabilities."
"The only thing is sometimes you can have a false positive."
"Given that I am in the small business space, I wish they would make it easier to operate Sentinel without being a Sentinel expert. Examples of things that could be easier are creating alerts and automations from scratch and designing workbooks."
"We do have in-built or out-of-the-box metrics that are shown on the dashboard, but it doesn't give the kind of metrics that we need from our environment whereby we need to check the meantime to detect and meantime to resolve an incident. I have to do it manually. I have to pull all the logs or all the alerts that are fed into Sentinel over a certain period. We do this on a monthly basis, so I go into Microsoft Sentinel and pull all the alerts or incidents we closed over a period of thirty days."
"If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable."
"Sentinel should be improved with more connectors. At the moment, it only covers a few vendors. If I remember correctly, only 100 products are supported natively in Sentinel, although you can connect them with syslog. But Microsoft should increase the number of native connectors to get logs into Sentinel."
"One key area that can be improved is by building a strong integration with our XDR platform."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Sentinel is fairly priced and pretty cost-effective."
"I have worked with a lot of SIEMs. We are using Sentinel three to four times more than other SIEMs that we have used. Azure Sentinel's only limitation is its price point. Sentinel costs a lot if your ingestion goes up to a certain point."
"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."
"The are two native advantages for customers that use M365 Security and Sentinel. The first advantage is that the log or security-event ingestion into Sentinel is free. Cost-wise, they're saving a lot and that is a major advantage."
"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."
"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."
"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."
"Microsoft can enhance the licensing side. I feel there is confusion sometimes... They should have a single license in which we have the opportunity to use the EDR or CASB solution."
"It’s a single license platform."
