With this kind of tool, students can save money by using open-source software while gaining experience in working with different logs and detection systems, leading to time savings during their studies.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
We couldn't calculate what would have been the cost if they had actually gotten compromised; however, they were in the process, so every investment was returned immediately.
On average, my SecOps team takes probably at least a quarter of the time, if not more, to remediate security incidents with Splunk Enterprise Security compared to our previous solution.
Customer support for Security Onion is very good
I can give it nine to 9.5 or 10 points for support.
I have participated in some community resources, and it is pretty good because it has a large community that has been around for years, which helps.
We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
We've had great customer success managers who have helped us navigate scaling from 600 gigs to 30 terabytes.
Security Onion is a highly scalable platform, making it suitable for medium to large-scale enterprises.
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.
It is one of the things that separates it from other tooling, and if not, it is the most scalable solution out there.
We have found no negative impact from scaling.
Since using Security Onion, we have not faced any issues or downtime, which indicates it is very stable.
Security Onion is reliable and is a good product, having no glitches or latency problems.
Security Onion is pretty stable, with the only significant issue being that I had to increase the storage.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
Splunk has been very reliable and very consistent.
We need more SMEs, and there is no mechanism to tell us about indexer or search head issues.
The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge.
A specific guideline for helping beginners understand the detection and investigation features of Security Onion would be beneficial.
AI is most helpful, so it is a good feature to add to Security Onion.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.
Security Onion does not require any cost, as it is open-source and free.
I do not have a license for Security Onion since I have the free version, meaning it does not cost me anything.
The enterprise version should be reasonably priced, not so expensive.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
I find it to be affordable, which is why every industry uses it.
One of the best features that Security Onion offers is that it is open source, free to install in a lab environment, and allows for monitoring network traffic and investigating potential attacks while integrating other tools such as Suricata, Zeek, and Elastic-based components that are useful for diving into the logs, along with its threat detection capabilities to see network activity, including port scans, unusual connections, and potential intrusion attempts.
The most valuable features of Security Onion are its threat detection capabilities, centralized log management system, and network security monitoring.
What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform.
This capability is useful for performance monitoring and issue identification.
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.
Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.
