Splunk Enterprise Security is an analytics-driven SIEM that helps to combat threats with actionable intelligence and advanced analytics at scale.
In my experience with Splunk Enterprise Security, the SIEM is far superior to my experience with Alienvault or Security Onion. Splunk Enterprise Security is FAR more stable, extensible, functional, easy to set up, and easier to use than either of these tools, so much so that I …
Splunk Enterprise Security is superior in the logging aspect and searching. That’s why it was easier to pick switch to Splunk Enterprise Security. Arcsight is however superior in the correlation and stability aspect. It’s very reliable and stable that we sometimes forget that …
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.
Security Onion works well for setting up within a Linux environment. This brings a new platform to run and maintain though. The application its self has helped to keep track of logs and vulnerabilities in the environment. Alert triage and case creation is simple to start and follow through to the end.
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.
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.
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 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.
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.
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.
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.
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.
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.
Other vendors may have a more robust solution but for our needs, Security Onion was the one to move forward with. We have tested some of the others but the cost of those platforms makes the ROI not as desirable. There is a learning curve with Security Onion but it is worth it for the value provided.
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.
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.
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.
