We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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.""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.""The main benefit is the ease of integration.""The most valuable features are its threat handling and detection. It's a powerful tool because it's based on machine learning and on the behavior of malware.""It is always correlating to IOCs for normal attacks, using Azure-related resources. For example, if any illegitimate IP starts unusual activity on our Azure firewall, then it automatically generates an alarm for us.""Sentinel is a SIEM and SOAR tool, so its automation is the best feature; we can reduce human interaction, freeing up our human resources.""Sentinel has features that have helped improve our security poster. It helped us in going ahead and identifying the gaps via analysis and focusing on the key elements.""It has a lot of great features."

More Microsoft Sentinel Pros →

"The product's initial setup phase was easy.""I like FortiSIEM because it integrates natively with our other Fortinet solutions and the Fortinet Fabric, but it also integrates with Cisco, Palo Alto and other security fabrics.""We're able to get real-timec as well as our customer networks that we're monitoring at all times.""The solution is very stable. It's run for years without the need to do anything except, add new patches when they are available, which are always a good idea to install.""Fortinet FortiSIEM is easy to use.""It's a very nice solution to work with.""The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor.""Its automated response feature has benefited our customer communication. Analysts feel more confident in providing timely responses."

More Fortinet FortiSIEM Pros →

"The visibility is amazing with easy dashboard creation.""The most valuable features for us include its robust log management capabilities, which allow us to efficiently handle and retain logs for extended periods as needed.""The varied prebuilt feature is the most valuable because it ensures that we have complete coverage over all of the key questions.""Deployment server for deploying changes in one go.""Splunk Enterprise Security is able to process a huge amount of data without any issues.""It has a drag-and-drop interface, so you don't need to know SQL or Java to construct a query on Splunk. The resolution time is about the same, but it took longer to discover the issue with ArcSight. Our previous solution took about an hour or more, but Splunk can do it within a few minutes or an hour at most.""The ability to analyze huge amounts of sales data and accurate prediction of sales forecasting is the most valuable feature.""It has a big user base, so the community is useful."

More Splunk Enterprise Security Pros →

Cons
"Sentinel's reporting is complex and can be more user-friendly.""Sometimes, it is hard for us to estimate the costs of Microsoft Sentinel.""The playbook development environment is not as rich as it should be. There are multiple occasions when we face problems while creating the playbook.""I can't think of anything other than just getting the name out there. I think a lot of customers don't fully understand the full capabilities of Azure Sentinel yet. It is kind of like when they're first starting to use Azure, it might not be something they first think about. So, they should just kind of get to the point where it is more widely used.""The KQL query does not function effectively with Windows 11 machines, and in the majority of machine-based investigations, KQL queries are essential for organizing the data during investigations.""They need to work with other security vendors. For example, we replaced our email gateway with Symantec, but we couldn't collect these logs with Azure Sentinel. Instead of collecting these logs with Azure Sentinel, we are collecting them on Qradar. We couldn't do it with Sentinel, which is a problem for us.""Its documentation is not so simple. It is easy for somebody who is Microsoft certified or more closely attached to Microsoft solutions. It is not easy for those who are working on open-source platforms. There isn't a central point where everything is documented, and there is no specific training or certification.""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."

More Microsoft Sentinel Cons →

"The process of installing Fortinet FortiSIEM and the customization of the alerts take too long.""The backup and recovery process for this solution needs improvement.""FortiSIEM could be better integrated with other vendors.""The stability of the product is an area of concern where improvements are required.""It's difficult to integrate unsupported devices with FortiSIEM compared to QRadar. It's easier to integrate and develop processes in QRadar. It's harder to develop a custom process in FortiSIEM.""Their product support, in general, is not that great. The product support is in the same ecosystem. Their support is improving but it's not that great.vvv""The interface needs some improvements because it's a bit cumbersome when you're trying to view items. It takes some time to get used to. Additionally, sometimes the scrolling does not work.""Our customers are noticing configuration available in the GUI interface and I think that they should be equal."

More Fortinet FortiSIEM Cons →

"A problem that we had recently had was we licensed it based on how much data you upload to them every day. Something changed in one our applications, and it started generating three to four times as many logs and. So now, we are trying to assemble something with parts of the Splunk API to warn ourselves, then turn it off and throttle it back more. However it would be better if they had something systematically built into the product that if you're getting close to your license, then to shut things down.""This is a costly solution.""The setup time is quite long.""The upgrading process could be smoother.""We'd like Splunk to reduce false positives.""The cluster environment should be improved. We have a cluster. In the Splunk cluster environment, in the case of heavy searches and heavy load, the Splunk cluster goes down, and we have to put it in the maintenance mode to get it back. We are not able to find the actual culprit for this issue. I know that cluster has RF and SF, but it has been down so many times. There should be something in Splunk to help users to find the reason and the solution for such issues.""The user access control could be much more granular, so that the admins can control r/w/x access for specific features of the product like dashboards, etc.""In terms of the interface, it could include some improvements for the look and feel."

Pricing and Cost Advice
  • "It comes with a Microsoft subscription which the customer has, so they don't have to invest somewhere else."
  • "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."
  • "I have had mixed feedback. At one point, I heard a client say that it sometimes seems more expensive. Most of the clients are on Office 365 or M365, and they are forced to take Azure SIEM because of the integration."
  • "It is kind of like a sliding scale. There are different tiers of pricing that go from $100 per day up to $3,500 per day. So, it just kind of depends on how much data is being stored. There can be additional costs to the standard license other than the additional data. It just kind of depends on what other services you're spinning up in Azure, or if you're using something like Azure log analytics."
  • "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."
  • "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."
  • "Azure Sentinel is very costly, or at least it appears to be very costly. The costs vary based on your ingestion and your retention charges."
  • More Microsoft Sentinel Pricing and Cost Advice →

  • "Please be cheaper and more simplified."
  • "We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
  • "Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
  • "Its price can be better. We are Fortinet partners, so we can get discounts, but its price can be an issue at the beginning for others. There is a licensing scheme for every case. There are three licensing schemes that we can choose from."
  • "The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
  • "They have a yearly subscription."
  • "The solution is available for both, perpetual and subscription licenses."
  • "Manageable, however would be better as pay as you go versus CapEX."
  • More Fortinet FortiSIEM Pricing and Cost Advice →

  • "Pricing and licensing is quite expensive. But for the value the product provides, it seems at par in the market."
  • "Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
  • "It is not cheap."
  • "Splunk Enterprise becomes extremely expensive after the 20GB/month license."
  • "You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
  • "Splunk licensing model might seem expensive but with all the gain in functionalities you will have compared to traditional SIEM solutions I think it’s worth the price."
  • "Pricing is pretty fair."
  • "While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
