Comparison Summary
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.

We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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 thing that Devo does better than other solutions is to give me the ability to write queries that look at multiple data sources and run fast. Most SIEMs don't do that. And I can do that by creating entity-based queries. Let's say I have a table which has Okta, a table which has G Suite, a table which has endpoint telemetry, and I have a table which has DNS telemetry. I can write a query that says, 'Join all these things together on IP, and where the IP matches in all these tables, return to me that subset of data, within these time windows.' I can break it down that way.""Devo helps us to unlock the full power of our data because they have more than 450 parsers, which means that we can ingest pretty much any type of log data.""It's very, very versatile.""Even if it's a relatively technical tool or platform, it's very intuitive and graphical. It's very appealing in terms of the user interface. The UI has a graphically interface with the raw data in a table. The table can be as big as you want it, depending on your use case. You can easily get a report combining your data, along with calculations and graphical dashboards. You don't need a lot of training, because the UI is relatively very intuitive.""The ability to have high performance, high-speed search capability is incredibly important for us. When it comes to doing security analysis, you don't want to be doing is sitting around waiting to get data back while an attacker is sitting on a network, actively attacking it. You need to be able to answer questions quickly. If I see an indicator of attack, I need to be able to rapidly pivot and find data, then analyze it and find more data to answer more questions. You need to be able to do that quickly. If I'm sitting around just waiting to get my first response, then it ends up moving too slow to keep up with the attacker. Devo's speed and performance allows us to query in real-time and keep up with what is actually happening on the network, then respond effectively to events.""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.""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."

"Sentinel uses Azure Logic Apps for automation, which is really powerful. This allows us to easily automate responses to incidents.""In Azure Sentinel, we have found, they do have a store in their capability. AI and intelligence features. We found that to be very helpful for us because some other things we do need to integrate again or find another vendor for the store""Having your logs put all in one place with machine learning working on those logs is a good feature. I don't need to start thinking, "Where are my logs?" My logs are in a centralized repository, like Log Analytics, which is why you can't use Sentinel without Log Analytics. Having all those logs in one place is an advantage.""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.""The log query feature has been the most valuable because it's very good. You can put your data on the cloud and run queues from Sentinel. It will do it all very fast. I love that I don't have to upload it to an Excel file and then manually look for a piece of information. Sentinel is much faster and is good for big databases.""It's pretty powerful and its performance is pretty good.""We have no complaints about the features or functionality.""Free ingestion for Azure logs (with E5 licence)"

More Microsoft Sentinel Pros →

"The connections to the database are very good and updating the data files is simple to do. The dashboards are useful and user-friendly.""There are quite a lot of things that we find useful. Splunk agents are useful and good. Its UI is quite impressive.""It allows us to digest the information, the data, the different data streams, so we can make decisions based upon information that we receive, and it is pretty robust.""Splunk is a user-friendly solution.""The ability to analyze huge amounts of sales data and accurate prediction of sales forecasting is the most valuable feature.""The most valuable feature is the log aggregation, being able to scan through all of the logs.""Its compatibility with other SIEMS is very useful.""It has quite extensive support in terms of integration. If you want to do anything, there are tools for that."

Cons
"There's always room to reduce the learning curve over how to deal with events and machine data. They could make the machine data simpler.""We only use the core functionality and one of the reasons for this is that their security operation center needs improvement.""Some third-parties don't have specific API connectors built, so we had to work with Devo to get the logs and parse the data using custom parsers, rather than an out-of-the-box solution.""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.""There's room for improvement within the GUI. There is also some room for improvement within the native parsers they support. But I can say that about pretty much any solution in this space.""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.""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."

More Devo Cons →

"They should integrate it with many other software-as-a-service providers and make connectors available so that you don't have to do any sort of log normalization.""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.""The interface could be more user-friendly. It''s a small improvement that they could make if they wanted to.""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.""Add more out-of-the-box connectors with other SaaS platforms/applications.""There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities. I'm thinking about things like the creation of workbooks, how you do threat-hunting, and the kinds of notifications you're getting... It takes time for people to ramp up on that and develop a familiarity or expertise with it.""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.""The only thing is sometimes you can have a false positive."

More Microsoft Sentinel Cons →

"Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue.""In terms of the interface, it could include some improvements for the look and feel.""An area of improvement would be the licensing of the solution. They need a free license, which would allow faster lead times.""Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this.""This is not really a monitoring solution.""If you have to do your own stuff, such as customized charts, it is a little bit more work, but once you're familiar with the Splunk query language, you can pretty much do whatever you want. In terms of features, it should probably have the features that other competitors provide.""It needs integration with a configuration management solution.""Its interface could be improved."

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."
