Q&A Highlights
Question: What is a better choice, Splunk or Azure Sentinel?
Answer: It would really depend on (1) which logs you need to ingest and (2) what are your use cases Splunk is easy for ingestion of anything, but the charge per GB/Day Indexed and it gets expensive as log volume increases. Splunk is good for operations style use cases (NOC), but requires ESS and isn't as easy to use or get data out of for SOC style use cases. Sentinel is good for endpoint Windows Defender Advanced Edition (extra cost, not the free version), analysis and malware findings, and when the data sources are all Windows events (O365/OneDrive/Email/ADFS), but costs go up substantially if the log sources aren't Microsoft events, and support for non-MSFT log sources is limited. Neither offers real UEBA capabilities IMO. Splunk has the add-on (entirely different architecture and systems), for the Caspida UEBA. MSFT will tout UEBA on Sentinel, but it's endpoint related (not network) and I've yet to see use cases on non-MSFT application data events.

Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature is definitely the ability that Devo has to ingest data. From the previous SIEM that I came from and helped my company administer, it really was the type of system where data was parsed on ingest. This meant that if you didn't build the parser efficiently or correctly, sometimes that would bring the system to its knees. You'd have a backlog of processing the logs as it was ingesting them.""The user experience [is] well thought out and the workflows are logical. The dashboards are intuitive and highly customizable.""In traditional BI solutions, you need to wait a lot of time to have the ability to create visualizations with the data and to do searches. With this kind of platform, you have that information in real-time.""The querying and the log-retention capabilities are pretty powerful. Those provide some of the biggest value-add for us.""Those 400 days of hot data mean that people can look for trends and at what happened in the past. And they can not only do so from a security point of view, but even for operational use cases. In the past, our operational norm was to keep live data for only 30 days. Our users were constantly asking us for at least 90 days, and we really couldn't even do that. That's one reason that having 400 days of live data is pretty huge. As our users start to use it and adopt this system, we expect people to be able to do those long-term analytics.""The strength of Devo is not only in that it is pretty intuitive, but it gives you the flexibility and creativity to merge feeds. The prime examples would be using the synthesis or union tables that give you phenomenal capabilities... The ability to use a synthesis or union table to combine all those feeds and make heads or tails of what's going on, and link it to go down a thread, is functionality that I hadn't seen before.""One of the biggest features of the UI is that you see the actual code of what you're doing in the graphical user interface, in a little window on the side. Whatever you're doing, you see the code, what's happening. And you can really quickly switch between using the GUI and using the code. That's really useful.""The most valuable feature is that it has native MSSP capabilities and maintains perfect data separation. It does all of that in a very easy-to-manage cloud-based solution."

"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.""We didn't have anything similar. So, it really provides value from the incidents and automation point of view. The overview of the security fabric is most valuable.""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.""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.""It has basic out-of-the-box integrations with multiple log sources.""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.""If you know how to do KQL (kusto query language) queries, which are how you query the log data inside Sentinel, the information is pretty rich. You can get down to a good level of detail regarding event information or notifications.""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."

More Microsoft Sentinel Pros →

"You can check up on security from the dashboards.""The flexibility of the search capability is most valuable. You can use it for more than just a basic log aggregator. It is powerful in that regard.""The connections to the database are very good and updating the data files is simple to do. The dashboards are useful and user-friendly.""What is nice about the solution is that it makes it easy to build the queries, search for the events and then do analysis.""The solution has plenty of features that are good.""The most valuable features in Splunk are the search function and the ability to run selected session reports. The session reports are important because I can use them to see what is going on in our environment weekly. Additionally, we can use the graph to see how often that particular event is happening.""The correlation capabilities are the first value that our clients say they like with Splunk.""Good for log collection and log management."

Cons
"An admin who is trying to audit user activity usually cannot go beyond a day in the UI. I would like to have access to pages and pages of that data, going back as far as the storage we have, so I could look at every command or search or deletion or anything that a user has run. As an admin, that would really help. Going back just a day in the UI is not going to help, and that means I have to find a different way to do that.""Technical support could be better.""There is room for improvement in the ability to parse different log types. I would go as far as to say the product is deficient in its ability to parse multiple, different log types, including logs from major vendors that are supported by competitors. Additionally, the time that it takes to turn around a supported parser for customers and common log source types, which are generally accepted standards in the industry, is not acceptable. This has impacted customer onboarding and customer relationships for us on multiple fronts.""The Activeboards feature is not as mature regarding the look and feel. Its functionality is mature, but the look and feel is not there. For example, if you have some data sets and are trying to get some graphics, you cannot change anything. There's just one format for the graphics. You cannot change the size of the font, the font itself, etc.""Some basic reporting mechanisms have room for improvement. Customers can do analysis by building Activeboards, Devo’s name for interactive dashboards. This capability is quite nice, but it is not a reporting engine. Devo does provide mechanisms to allow third-party tools to query data via their API, which is great. However, a lot of folks like or want a reporting engine, per se, and Devo simply doesn't have that. This may or may not be by design.""From our experience, the Devo agent needs some work. They built it on top of OS Query's open-source framework. It seems like it wasn't tuned properly to handle a large volume of Windows event logs. In our experience, there would definitely be some room for improvement. A lot of SIEMs on the market have their own agent infrastructure. I think Devo's working towards that, but I think that it needs some improvement as far as keeping up with high-volume environments.""Where Devo has room for improvement is the data ingestion and parsing. We tend to have to work with the Devo support team to bring on and ingest new sources of data.""We only use the core functionality and one of the reasons for this is that their security operation center needs improvement."

More Devo Cons →

"The only thing is sometimes you can have a false positive.""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.""If Azure Sentinel had the ability to ingest Azure services from different tenants into another tenant that was hosting Azure Sentinel, and not lose any metadata, that would be a huge benefit to a lot of companies.""We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed.""Azure Sentinel will be directly competing with tools such as Splunk or Qradar. These are very established kinds of a product that have been around for the last seven, eight years or more.""I would like to be able to monitor applications outside of the Azure Cloud.""Multi-tenancy, in my opinion, needs to be improved. I believe it can do better as a managed service provider.""If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable."

More Microsoft Sentinel Cons →

"Splunk could be improved by reducing the cost. The cost is one of the biggest challenges for us in keeping to our production requirements.""I'd say I am happy with the technical support, not elated. They provide great support, but sometimes they don't have the answers that I need.""In the next releases, I would like to see more pricing flexibility.""There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side.""The complexity could be worked on so that it's even easier and faster.""The documentation is in definite need of improvement.""It needs integration with a configuration management solution.""It's difficult to set up initially, and their billing model is also a bit complicated."

Pricing and Cost Advice
  • "We have an OEM agreement with Devo. It is very similar to the standard licensing agreement because we are charged in the same way as any other customer, e.g., we use the backroom."
  • "I'm not involved in the financial aspect, but I think the licensing costs are similar to other solutions. If all the solutions have a similar cost, Devo provides more for the money."
  • "Devo is definitely cheaper than Splunk. There's no doubt about that. The value from Devo is good. It's definitely more valuable to me than QRadar or LogRhythm or any of the old, traditional SIEMs."
  • "[Devo was] in the ballpark with at least a couple of the other front-runners that we were looking at. Devo is a good value and, given the quality of the product, I would expect to pay more."
  • "Be cautious of metadata inclusion for log types in pricing, as there are some "gotchas" with that."
  • "Devo was very cost-competitive... Devo did come with that 400 days of hot data, and that was not the case with other products."
  • "Our licensing fees are billed annually and per terabyte."
  • "I like the pricing very much. They keep it simple. It is a single price based on data ingested, and they do it on an average. If you get a spike of data that flows in, they will not stick it to you or charge you for that. They are very fair about that."
  • More Devo 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 →

  • "I think that most of the monitoring solutions are expensive."
  • "I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
  • "Our customers often complain that the price of Splunk is too high."
  • "Licensing is a yearly, one-time cost."
  • "The price is comparable."
  • "The pricing model is expensive and a nightmare based on the amount of data."
  • "The solution is a little expensive."
  • "It is economical than other solutions."
