We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The solution has features that helped improve the security posture of our clients. It provides the ability to correlate a large variety of log sources very cost-effectively, especially for Microsoft sources.""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.""The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities.""There are some very powerful features to Sentinel, such as the integration of various connectors. We have a lot of departments that use both IaaS and SaaS services, including M365 as well as Azure services. The ability to leverage connectors into these environments allows for large-scale data injection.""The most valuable feature is the alert notifications, which are categorized by severity levels: informational, low, medium, and high.""The solution offers a lot of data on events. It helps us create specific detection strategies.""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 most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."

More Microsoft Sentinel Pros →

"FortiSIEM's log correlation is good.""Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had.""The most valuable feature of Fortinet FortiSIEM is the user and entity behave as analytics(UEBA). This feature mixes your data and provides useful information based on the behavior of the targeted.""The seamless integration with FortiGate is the solution's most valuable aspect.""It gives us the opportunity to generate notifications based upon rules that get triggered, and the rules could be specific to PCI, HIPAA, GIBA, NIST, and so forth.""We're able to get real-timec as well as our customer networks that we're monitoring at all times.""One of the most valuable features is that we can combine SOC and NOC operations in the same tool. We can provide NOC and SOC services in the same tool for two separate teams. There are plenty of third-party solutions that integrate with FortiSIEM. All these solutions already have a ready integration, and we have the possibility to create a custom connector for these solutions. Its reports are also very good.""FortiSIEM is a great tool for making security processes transparent."

More Fortinet FortiSIEM Pros →

"It is very stable. We have not had any problems.""Splunk has helped improve our company's resilience level.""It is easy to use in any environment.""It has virtual visualization, and other products do not.""It gives us the liberty to do more in terms of use cases.""The integration is seamless with many devices and operating systems.""The solution has proven to be quite stable.""The client site login is pretty extensible and probably cost-effective."

Cons
"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.""Sentinel still has some anomalies. For example, sometimes when we write a query for log analysis with KQL, it doesn't give us the data in a proper way... Also, the fields or columns could be improved. Sometimes, it is not giving the desired results and there is a blank field.""We'd like also a better ticketing system, which is older.""The data connectors for third-party tools could be improved, as some aren't available in Sentinel. They need to be available in the data connector panel.""We'd like to see more connectors.""Sentinel provides decent visibility, but it's sometimes a little cumbersome to get to the information I want because there is so much information. I would also like to see more seamless integration between Sentinel and third-party security products.""If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable.""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."

More Microsoft Sentinel Cons →

"Fortinet FortiSIEM could improve by having better integration and extensions. This would benefit by allowing us to give more rules.""There is no proper guide for integration or configuration.""Areas for improvement would be the ease of use and the integration with Fortinet's own products.""The solution needs to do a better job with third party integration. Right now, that's lacking on the solution. I specifically am talking about the AWS environment. Most of the AWS environment products do not have that capability to integrate.""The dashboard needs to improve.""With FortiSIEM, the issue has to do with the ways we can generate a report. It's not as flexible compared to that with other SIEM tools, like Splunk.""The UI could improve in Fortinet FortiSIEM. Humans view the UI frequently for data and if it was more visually pleasing it would be beneficial.""They should enhance the solution's AI capabilities, including XDR and EDR."

More Fortinet FortiSIEM Cons →

"Our two main complaints are about the difficulty of the initial setup and the licensing model.""Its interface and usability can always be improved.""When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time.""The documentation is in definite need of improvement.""Missing capability for audio/video and image processing.""I would like Splunk to add more integration. QRadar has many indications with more products than Splunk.""The UI can be difficult to understand for non-technical people.""The solution could use a different licensing model."

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."
