Sentinel is the best "cloud-native" in the market yet, so if the organization has a cloud presence (which almost everyone has) then Sentinel is the right choice for having a single pane of glass for all your security monitoring needs. Sentinel is a very good tool for log analysis and event management purposes as well. With KQL and ASIM parsers, organizations can retrieve invaluable insights even from the most complex data. And of course, Sentinel is a great choice for automating the incident response process to a very good extent.

Splunk
Well suited: Splunk ES is highly recommended in an environment with many data sources and experienced computer engineers. It has a steep learning curve, but once that hurdle is crossed, it is absolutely a beast. It is also very expensive, so a company putting a high amount of budget in Security is needed. Not well suited: Splunk ES is not recommended if a company has only a few sources and some non-technical IT users. The price won't justify the fewer data sources and scratching just the surface level. Moreover, non-technical IT users would be better off with something that has a query builder, unlike Splunk.

Pros
Microsoft
  • It has a native integration with all Microsoft products, from Entra to Azure, Microsoft 365
  • Being built upon native Azure functionality benefits in automation and infrastructual solutions
  • The KQL language is relatively easy to learn and powerful.
  • Microsoft is listening very careful to the customers and develops new functionality at a fast pace

  • Advanced Threat Detection and Correlation: ES stands out in its ability to detect sophisticated threats by correlating data from multiple sources. For instance, it can identify unusual patterns in user behavior, cross-referencing with network logs to flag potential insider threats.
  • Real-time Monitoring and Alerting: ES offers robust real-time monitoring capabilities. It excels in promptly alerting us to critical security events, such as suspicious network traffic spikes or unauthorized access attempts, allowing for immediate response.
  • Comprehensive Log Analysis: ES ingests and analyzes an extensive range of log data. It's particularly adept at parsing and making sense of complex log formats, making it a versatile tool for understanding system activities and security events.

Cons
Microsoft
  • It takes some time to learn how to use and install it properly, and it does not connect effectively with external PaaS systems such as Salesforce CRM, Salesforce Commerce Cloud, and so on.
  • Microsoft can simplify the display of the logs to make them easier to study, and the user interface occasionally delays, which can also be enhanced.

Splunk
  • ES on the cloud (SaaS) has too many limitations with platform administration.
  • Supported integrations are not always on par with enterprise support especially when dependent on 3rd-party proprietary APIs.
  • In later versions, unforeseen glitches seem to show up that have no resolution except version upgrade. This used to not be the case in prior versions which were very stable.

Usability

The Microsoft Azure Sentinel solution is very good and even better if you use Azure. It's easy to implement and learn how to use the tool with an intuitive and simple interface. New updates are happening to always bring new news and improve the experience and usability. The solution brings reliability as it is from a very reliable manufacturer.

You definitely need to learn how to use Splunk to get the most of the tool. There are many courses available for free to get up to speed on the usability of the tool but it's not that simple. It will take time to digest all the data and to understand how to query for what you are looking for.

ES requires a very performant infrastructure: if it has it's performant, otherwise not. I had situation with a very performant infrastructure and I didn't notized that it was a distributed architecture, it seemed that there ware few data on my PC, othewise I experienced less performant infrastructures with less performaces.

It's good when it's responsive, but I've had times where I had to wait quite a while for a response. But these are typically the exceptions rather than the rule. When you do get a response it is always well-informed and appropriate. I would say they've been trending better over time with this.

I experienced only on-line training, but the trainers were very professional and competent. Maybe it could be more useful if they also have an experience in projects because sometimes they didn't have a real project experience to communicate to the students. Anyway, it was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself, aven if I have more than 10 years of Splunk activity experience.

It was very interesting and I learned many thing that's very difficoult (or maybe impossible!) to have by myself. The only problem was that, when I worked with the Splunk Professional Services, I found some difference between the training contents and the information from PS. In addition is required a long experience on Splunk Enterprise for the data ingestion part, in other words I'm able to work with ES because I'm worling on Splunk since 11 years, otherwise I'd some problem.

The key advantage of using Sentinel lies in Microsoft already being a renowned name in cloud services. Hence, the Collection of data at the cloud scale across all users, devices, applications, and infrastructure, both on-premises and especially in the MS Cloud, is super easy. Additionally, leveraging Threat Intel from Microsoft itself gives a sense of security, given their years of experience in the collection of intel. The AI and Machine learning features provided by MS is one of the finest.

Splunk enterprise is the only solution that we’ve been able to identify that provides risk based alerting, which allows our SOC to reduce analyst fatigue which would be a huge problem without it. Before RBA, there were thousands of alerts a day and it was impossible to review all of them

for my exterience, unit pricing and billing frequency are correct. As I already said, I hint to have more discount flexibility, expecially with new customers, because there are competitors less expensive and very aggressive that are dangerous. In addition the possibility to don't pay the license for the development period could be a very interesting feature for the final customers.

- 8 out of 10 and took 2 for the data pipeline and administration part. Even if you'd like to improve yourself or your team, you have to pay a lot of money and it could be more than GIAC education + cert. - Normalization for Data models and CPU-based searches can be a problem sometimes.

I had a fantastic experience with Splunk Professional Services: they worked with us in our last SON project (a SOC migration for a very large customer) and helped to build a multi tenent environment even if ES isn't a multi tenant platform. Th Splunk PS was a very professional and competent people, he is italian and was able to speak with our italian customers.

Return on Investment
Microsoft
  • Microsoft Sentinel is a good investment, especially when sided with other solutions such as Microsoft 365 Defender, as it provides 360° protection on every level of the infrastructure.
  • When deployed on infrastructures that have never had an SIEM, Microsoft Sentinel helps to assess vulnerabilities and misconfigurations.
  • As with any other SIEM, Microsoft Sentinel basically eliminates the need to put effort into every single platform (like EDR, NDR, XDR) and converge that effort on a single product that correlates and orchestrates the rest.

  • ES has highly impacted ROI because as the customer of the ES the work we do for creating use cases for clients in terms of security-related aspects by their logs has given more return than investment.
  • The correlation searches we run to get detailed results from the Data models are very less time-consuming than Splunk Enterprise itself we can get quick responses to the use cases and dashboards populated because of ES.
  • The CIM compliance feature is ES has made more jobs easy in the terms of finding more Authentication related data we can get data onboarded in the Email data model from O365 and search is email data model instead of searching for particular indexes.
