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

"Being able to aggregate detection and alerts from various sources is valuable. Like everyone else, we have a wide range of tools in our shop. We are able to stop at one spot and look at all the data. All the data is able to come through, and we can then jump from source to source or index to index. We can dig deep whenever we need to and get a good high-level understanding."
"Overall, it's a good tool."
"Splunk Enterprise Security has the capability to pull the report from anytime or any respective time, or if I need it from all the time, then it can be helpful."
"Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language, allowing extensive customization and analysis capabilities."
"Splunk simplifies the information, and it gives you charts and different means of seeing that information, making it easily understandable for people."
"It's basically one of the best SIEM products on the market."
"Splunk may be more costly upfront, but in the long run, it saves on time and man-hours."
"In my experience, Splunk Enterprise Security detects incidents approximately 20% much faster than other tools."
"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 a separate config file in addition to the core configuration."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"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."
"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."
"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."
"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."
 

Cons

"The biggest thing with Splunk is making sure that the documentation is maintained."
"We had some connections issues with the solution at the beginning."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
"Certain sections of the developer documentation could use some updating and clarification."
"My organization does not completely utilize risk-based alerting in Splunk Enterprise Security as it's not fully mature."
"Unlike other cloud based analytics platforms, at the time of this writing Splunk Cloud is a dedicated instance per customer rather than a shared tenancy platform."
"Splunk can be an expensive solution. Technical support could be improved as well."
"One complaint is that it is very expensive for organizations."
"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."
"The filtering has room for improvement."
"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 always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
 

Pricing and Cost Advice

"The solution is costly."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."
"The solution is a little expensive."
"The cost is on the high end, which makes it difficult for some organizations to use."
"The pricing and licensing of the product are quite high."
"The price of Splunk Enterprise Security is high."
"The pricing model is expensive and a nightmare based on the amount of data."
"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
