Qradar is easy for first-timers. Easy to deploy and manage but if you need an advanced solution for ML, Anomaly Detection you need to use Splunk. Qradar is solid, too. But Splunk has advanced functionality for detection and automation.
Microsoft Defender XDR is well suited for organizations already invested in the Microsoft Ecosystem - including Microsoft 365, Azure Ad and INTune. For example, in scenarios where you need to correlament the fishing attacks with the closing point behavior and identity agreement, Microsoft Defender XDR does a big task of sewing the timeline of a full attack simultaneously and even automatically removing. This hybrid function is also ideal for the environment, where safety visibility in distance tools, cloud apps and email is important. Microsoft Defender XDR provides centralized insight and response in all these domains without the requirement of many devices. However, it is less suitable in the atmosphere with diverse or non-microsoft infrastructure, such as an organization running a mixture of Linux server, Google work area or third-party EDR tools. Cross-platform support is still developing, and integration of the microsoft ecosystem often requires additional configurations or third-party connectors. For companies of that situation, Microsoft Defender XDR cannot give its full value from the XDR box.
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.
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.
The software uses advanced AI and machine learning algorithms to monitor activities and detect any anomalies immediately, protecting our financial data.
Automated responses to known threats reduce the impact of possible incidents and improve our security posture.
Microsoft 365 Defender easily combines with other Microsoft 365 services and external security solutions, providing a complete and unified security solution.
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.
Improved algorithms to minimize false positives in threat detection, reducing the impact on security teams and preventing unnecessary investigations into non-threatening incidents.
Advanced User-Friendly Interface:
Streamlined and intuitive user interface for the centralized dashboard, making it more accessible for security professionals with varying levels of expertise.
Greater Third-Party Integration:
Increased compatibility and integration capabilities with a broader range of third-party security tools
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.
We are pleased with the product and have no plans to look for alternatives. We are deeply invested in Microsoft ecosystem and Defender XDR provides seamless integration to other Microsoft products. For academic institution pricing is also quite affordable. In the contrary, we hope to extend the scope of the product for our entire environment.
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.
Overall the UI is modern and OK to use. Attack story is quite nice visual of incident. Advanced hunting supports autocomplete so that helps doing KQL-queries efficiently. The product is quite comprehensive and one can get lost in the vast UI. Learning curve is quite high and navigation is complex. As product also continues to evolve the UI might change somewhat.
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.
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.
In our experience there has been very little downtime for Microsot Defender XDR. For us there hasn’t been any single incident where we needed the product and it was not available.
Most of the time the product is as responsive as you might expect from cloud product. Occasionly the product is little slugish, this has been at most a slight irritation. Reports generate quickly ennough for our needs. We also not have found that Defender XDR slows down systems that it is integrated with
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.
Their support throughout our onboarding of the product was fabulous. They not only took the time to carefully explain to teams not as well equipped with the lingo but explained to the tech team how to teach the other teams to be successful. They never once seemed impatient or annoyed with basic questions and didn’t pretend to know something when they needed to research an answer
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.
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.
Microsoft Provides a good training for the Microsoft 365 Defender and has a good learning paths to learn and take the exams and get your Certifications.
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.
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.
seemless and almost transparent. can be deployed by script if needed so every endpoint on our system get's it. if you have intune it gets dumped on the the endpoint by policy so nothing escapes it
Our product in that area, for instance as a security platform and for us it is for the moment really bad point. We started to move in that direction that there is that disconnect from the client management. So if there is some action that needs to be executed detected by security team, there is not an easy way to make that available to the team that is responsible for managing the identities as users, as the devices
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.
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.
Azure cloud provides techical power to scale the product for whole organization. From organizational point of view scaling Defender XDR for various IT teams needs good collaboration and clear norms that all teams must agree to and follow.
- 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.
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.
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.
