Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Has ensured compliance by centralizing log data and supporting secure connections
We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I really like the user interface and how it works."
"The features of Splunk Enterprise Security that I appreciate the most include the SPL search."
"The ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"The Splunk user community and forum are most valuable."
"The ability to view all of these different logs, then drilling down into specific times or into specific data sources, has proved to be the greatest aspect in decreasing our troubleshooting overhead time."
"It is easy to use in any environment."
"It is the best tool if you have a complex environment or if data ingestion is too huge."
"Splunk was good for us because of the support, the documentation, the scalability, the stability."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"Syslog-ng has a separate config file in addition to the core configuration."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
 

Cons

"To improve Splunk Enterprise Security, I would suggest allowing third-party SOAR solutions to work with it."
"There is room for improvement for Splunk Enterprise Security. I moved away from Security Onion before switching to Splunk because Splunk was promising with Splunk AI, but now I am questioning if I made the right decision given that everybody is moving towards the AI aspect, especially since Splunk told me I cannot use Splunk AI on my platform and Security Onion already has the Gen-Sec SOC."
"Being able to have a one-stop shop where you have the alert, but then you can generate the case right there from Splunk Enterprise Security instead of having to pivot to another tool such as Mission Control. You do not have to keep bouncing between them, so if you could do it all in one place, that would be great. The new release is supposed to start getting in that direction."
"Splunk Enterprise Security documentation exists, but compared to Palo Alto, Palo Alto has more knowledge base articles."
"The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."
"From the commercial point of view, they have to bring down their costs. It's a bit pricey right now."
"In my opinion, it is too expensive for our projects."
"Splunk can improve its third-party device application plugins."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
"The filtering has room for improvement."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
 

Pricing and Cost Advice

"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."
"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."
"Pricing is pretty fair."
"Expensive compared to other options."
"There is an annual license required to use this solution."
"The subscription is monthly."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"Splunk is a bit pricier, but the benefits and ROI are huge."
"Syslog-ng is a free open-source solution."
"Syslog-ng is open-source."
