Splunk Enterprise Security is an analytics-driven SIEM that helps to combat threats with actionable intelligence and advanced analytics at scale.
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 …
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 …
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 …
I did not choose this product. Overall although I like ES, I think Sentinel in certain ways is the superior product. The Kusto Query language is a lot easier to use. For instance anything that requires manual parsing in query can be more difficult with this product. Also some …
We piloted Sentinel for one of our regional logistics hubs but it struggled to handle our volume on-prem iot and telematics data cleanly. Splunk on the other hand gave us more control than its competitors
Using Splunk Enterprise Security allows the combination of security data sources from any number of services or products, giving analysts a single view of the entire security footprint throughout the organization and correlating events across services that may otherwise be …
Specifically for Microsoft Sentinel, it's going to have what's next to no value if you're not on Azure. You have to be in as your customer. If you want greater insight into what is going on in your cloud environment, turn Microsoft Sentinel on, but focus on where you enable it. You're not going to turn it on to see everything because it's not like focus on the areas where you are at risk or you believe you're at risk or something that you're, depending on your environment, do you have multiple subscriptions? Do you have a Microsoft Sentinel subscription that you just turned on, but it's not getting the visibility, and then you can alert on stuff that goes out of trend, etc.?
Based on my experience, Splunk is a strong git for some environments and a poor match for others. The distinction is primarily based on infrastructure complexity and budget. It's perfect for large enterprises with a mix of on-prem/cloud infrastructure. It's not a perfect match for small teams with restricted resources.
Strong integration with the Microsoft security ecosystem allows seamless connection to services such as Microsoft Defender, Microsoft 365, and Azure. This makes it easy to bring together identity, endpoint, and cloud signals to support investigation and detection scenarios.
Effective correlation of alerts and incidents in collaboration with Microsoft Defender XDR helps combine related signals into higher‑fidelity incidents. This reduces noise and improves visibility into attack context, making investigations more efficient.
High scalability for data ingestion and processing enables large volumes of security telemetry to be handled efficiently.
Writes Powerful Queries: The queries that can be written using the Splunk Query Language are very powerful and highly customizable to meet every need. Ex: Writing queries to search the intersection of two different sources like Network and Endpoint Logs.
Offers Dashboard Abilities: Helps build complex panels for Dashboards in addition to providing several out-of-the-box panels. Ex: creating panels to calculate the performance of analysts in a given timezone.
Helpful Search Aids: It helps to set up complex custom alerts very easily. The interesting fields section is very helpful while threat hunting. Ex: It shows all the users and the frequency of each in a failed login event. The user list on the interesting fields is useful to look for suspicious logins.
I think it's primarily going to be cost, since Microsoft Sentinel uses Microsoft Log Analytics as its base, right? So storing the logs and log retention is very expensive. That might result in users not adopting it as quickly. Second, I think Copilot for security can just do summarization and not many remediation tasks. In the future, we would like to see Copilot create many playbooks, including all box playbooks, to remediate many security issues.
Improved User Interface Customization: While the interface is generally intuitive, providing more options for users to customize their dashboards and views would enhance the overall user experience. Tailoring the interface to specific roles or use cases could be a valuable addition.
Simplified Alert Management: Streamlining the process of managing alerts, such as grouping or categorizing them based on severity or type, would make it easier for security teams to prioritize and respond to incidents effectively.
Expanded Threat Intelligence Feeds: Increasing the variety and sources of threat intelligence feeds available within ES would provide a broader context for identifying and mitigating emerging threats, ensuring a more comprehensive defense against evolving attack vectors.
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.
Maintaining hundreds or even 1000+ SOC use cases is really difficult, considering that the Data sources may not always send the data. A module that detects data freshness issues and detect data format changes would be a great help. the main challenge today using Splunk Enterprise Security is making sure that the detection rules are still working properly given all the changes that occur in data source applications. Also, maintaining the data collects on tens of thousands of servers and more than 100k workstations is a real company IT challenge: the splunkbase forwarder may not support old OS anymore, while these are the most important to monitor. Moving to the Open Telemetry collector has become essential so that only 1 agent is required for both SIEM and application observability.
It takes a long time for items to load if you are just generally searching through logs. It is best to use the data models which load faster but can be strange in terms of what is coming from which logs where. Yes, you can look it up, but this also requires familiarity with where things are and how to look them up.
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.
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.
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.
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.
We have a 100% success rate on all our ES implementations due to the amazing documentation and Splunk enablement on the subject.
Our Splunk ES business has grown 100% YoY for the last 3 years.
In terms of long term management and maintenance, ES has been highly stable and predictable, reducing our overhead on costly services team for ad hoc maintenance work.
