Splunk is software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface. It captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.
Prior to using Sentinel, we were using Splunk specifically Splunk Enterprise Security and Splunk Cloud, so their on-prem and their cloud-based products. We switched originally for cost reasons, specifically cost control, but I have found that the ability to create reports, the …
Microsoft Sentinel feels on another different level from these solutions , all in the cloud . No need for troubleshooting , deployment or upgrades. Constant updates from the vendor and good support
Microsoft Sentinel excels in cloud-native scalability, Microsoft ecosystem integration, and AI-driven threat detection with UEBA and Fusion rules, offering faster deployment and lower costs (48% cheaper per Forrester) than Splunk, QRadar, Exabeam, SentinelOne, Securonix, and …
Well before there was Microsoft Sentinel, you had other competing products like ArcSight or Splunk, et cetera. I think they have their own qualities, but the Microsoft integration story is really why we're using it.
As mentioned, the product was part of the purchase of several Microsoft Suites that we did earlier last year and with 200 licenses included, we can exclude those from the other SIEM and SOAR product, it just work well with the Microsoft's environment that we partially have Is …
ArcSight is an on-prem solution that has a different approach than Sentinel.
In a basis this product is more complex to maintain and deploy. The query functionality in Sentinel is more powerful and easier to maintain. ArcSight has a much slower performance and an interface that …
Microsoft Sentinel really goes the extra mile when it comes to an SIEM that slowly improves toward a proper SOAR, this may be the best selling point of the entire solution. Highly scalable, cloud-based, and nearly perfect when dealing with Microsoft-based infrastructures, …
As the vast majority of our users have Windows machine and uses all 365 cloud features, we finally decided not to implement any 3rd party security solutions on desktops/laptops in order to keep our infrastructure simple. In this case, Microsoft Sentinel is the best way to …
While both are market-leading SIEM platforms, they cater to different environments and organization priorities. The choice often comes down to a company's existing infrastructure, integration needs, and long-term security strategy. Deployment and architecture - Splunk offeres …
Splunk is certainly much more versatile than either of these three products. Unless ArcSight makes a "connector" for your product, you will be required to use Flex Connectors which is an additional license and apparently requires some serious development. Without Logger, you …
It's certainly well-suited in environments that rely heavily on Microsoft products, and it's well-suited for environments where you have other business drivers to go to the E5 license. If I were to say where I would not and why, I only gave it a seven on the recommendation, that answer would probably vary if you already owned E5 or not. It's extremely expensive. And if there are other alternatives, if you don't have any other driving reason to go to E5, I would coach you not to go to Microsoft Sentinel. But if you're there, it's a fantastic property. It's certainly part of the cost argument for moving to E5, but it's only a part. It can't by itself justify the move to E5.
In the current lot of hundreds of SIEM solutions out there in the market, ArcSight ESM is fairly less expensive with strong fundamentals in place. The log ingestion, correlation are very well performing and totally worth ROI. However, the tool has lost its way when it comes to staying abreast with current feature curve of SIEM technology and the evolution has not been done by MicroFocus. Search times are high and there is no major plug-in that has been introduced as part of the product life cycle.
It's well suited for what I do, which is network security operations. And that's for anything from troubleshooting incidents, troubleshooting performance, troubleshooting for the purpose of a compliance and auditing. It's not best suited for users who are new in terms of they're new to the product and they have expectations that probably Splunk cannot meet.
It's the scale. Having built-in detections and vulnerabilities and the ability to see into the traffic flows is absolutely key. Look at it from my perspective as network security. We want to see what's going on east, west, between all the kinds of subscriptions and the tenants. We don't have that. We don't have that with any other product. Microsoft Sentinel gives us that kind of visibility.
Integration with smart logger and ESM to create rules and easy management of the same.
Easy integration with all end point security management tool(IPS/IDS, Firewall, Anti-Virus) and their consolidated output at a single place to effectively rectifying true and false positives.
An area for improvement is how case management is surfaced within the Microsoft Sentinel experience, as clearer integration into Sentinel workflows would reduce context switching and improve incident handling.
There is an opportunity to further expand agentic, autonomous investigation and response capabilities.
We are using Splunk extensively in our projects and we have recently upgraded to Splunk version 6.0 which is quite efficient and giving expected results. We keep track of updates and new features Splunk introduces periodically and try to introduce those features in our day to day activities for improvement in our reporting system and other tasks.
Because, as I said, it still lacks a lot of things, like many playbooks outside the Copilot integrations and the actual remediation. For example, for Microsoft Sentinel and SAP, I would want to see Copilot doing a lot of remediations in Microsoft Sentinel at SAPN, like executing the transaction code, maybe creating certain increases, or remediating stuff like that, which is all customized.
Overall, it is a good investment in order for an organization to stay compliant and stay secure from all the wild things happening. It is definitely a cost effective tool with some good features including correlation, log storage, reporting and dashboards. If a customer is looking for advanced set of features, then I would highly not recommend this.
You can literally throw in a single word into Splunk and it will pull back all instances of that word across all of your logs for the time span you select (provided you have permission to see that data). We have several users who have taken a few of the free courses from Splunk that are able to pull data out of it everyday with little help at all.
Microsoft support is one of the highest rated on the market. It has global and multilingual support. Calls can be made over the phone and the solution is virtually instantaneous with the help of Microsoft engineers. It's great!
I personally haven't reached the support team, however, the engineers never complained about the Arcsight support team. We had some issues with the tool in the past but every time we reached the support, all issues were resolved in a timely manner.
Splunk maintains a well resourced support system that has been consistent since we purchased the product. They help out in a timely manner and provide expert level information as needed. We typically open cases online and communicate when possible via e-mail and are able to resolve most issues with that method.
The online course was simple clear and described the main capabilities of the solution. There is also an initial module that can be done for free so anyone can familiarize themselves with the functionality of this solution. On the other hand, however, there could be more free online courses. Maybe even with a certificate, this would broaden the group of people who are familiar with the platform while increasing familiarity with the solution itself.
Microsoft Sentinel excels in cloud-native scalability, Microsoft ecosystem integration, and AI-driven threat detection with UEBA and Fusion rules, offering faster deployment and lower costs (48% cheaper per Forrester) than Splunk, QRadar, Exabeam, SentinelOne, Securonix, and Wazuh. It lags in third-party integrations and syslog parsing. Organizations choose Microsoft Sentinel for its cost-effectiveness, automation, and Microsoft synergy, especially in Azure-heavy environments, though Splunk and Exabeam lead in flexibility and UEBA, respectively.
Multiple platforms are already supported by Arcsight. Support is good. Scripts can be used to get data from multiple threat intel sources & the same can be used in correlation rules to detect any suspicious activity. Reporting features are good & you can check any backdated information within new clicks.
I didn't get to fully evaluate Logstash as our corporation was already using Logstash, but both seemed like viable solutions to the problem that we were having. I wanted to evaluate Logstash some more, both did seem like they would work for the business needs that we had, we went with splunk as many teams were already using it.
As any cybersecurity product, this has to be more with risk to avoid loss in case of a ransomware that more than relate to a productivity increase. Maybe the impact could be that instead of having people that are checking 24/7 the dashboard, you could implement Sentinel and have less people checking that or people with less expertise. So the saving will be a minor but will be a saving in the cost of your team.
Logger helps us to decrease incident response times.
It also decreased our project times with the man/day calculations. Before this solution, it may take up to 10 men/days to do something. After this, it becomes nearly half of the time.
I don't have any numbers to share but Splunk has positively served as a 24/7 monitoring tool that has saved hours of work by self-detecting, saving statistics and alerting problems in the system or from external interfaces as soon as they happen.
Splunk dashboards does a solid job in collecting, analyzing data and creating reports that contain an entire day's activity and then automatically sent out to the business.
Splunk is very easy to learn and very useful to any program or business application.
