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.

IT Infrastructure & Cloud Security Manager at Thux

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

"Its integration is most valuable, and its UI is also pretty much easy."

"They are a good partner for Google Cloud. It provides great visibility, threat detection, and proactive mitigation of risks for our mutual consumers."

"The solution is very fast and succinct."

"I find it beneficial that Splunk Enterprise Security easily integrates with other tools. Due to its excellent API capabilities, it facilitates connections with various cybersecurity tools."

"The product is pretty good, we are pretty satisfied with it, and it does what it does."

"It's basically one of the best SIEM products on the market."

"It gives us the liberty to do more in terms of use cases."

"The features I find most valuable in Splunk Enterprise Security are Incident Review, Security Essentials, Asset and Identity Management, and Machine Learning Toolkit."

More Splunk Enterprise Security pros

"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."

"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."

"The ability to extract and store the logs is the most valuable feature of syslog-ng."

"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."

"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."

Cons

"The integration with all our tool sets felt like we were reinventing the wheel, which was a pain point for us."

"We usually have to follow up with technical support on our open cases."

"We were inundated with the amount of alerts and alarms that we could get out of it. It is also a resource hog and we didn't have the resources to support it on-prem so we're taking it offline now."

"I would like to see an updated dashboard. The dashboard is a little out-of-date. It could be made prettier."

"There is improvement needed when importing from some types of data sources. Most of the time you have to do some customization for the data because not everything is working the way it should."

"The way Splunk Enterprise Security could improve is by pulling in and mapping my DHCP data and tracking users' IP addresses as it changes throughout sessions, and being able to keep track of who is actually assigned to what IP address more natively."

"I feel as though a major focus of upcoming releases should be set on Machine Learning, Predictive Analytics, and I would enjoy to see more security focused add-ons and apps developed by the vendor."

"Splunk Enterprise Security has not helped reduce our alert volume."

More Splunk Enterprise Security cons

"There is always the potential for additional integration and protocol extensions."

"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."

"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."

"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."

"There is room for improvement in terms of observability."

Pricing and Cost Advice

"It is a bit costly."

"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."

"The pricing is very complicated, and it is very pricey. You do require a lot of different licenses in order to get a comprehensive solution that is not just the SIEM solution."

"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."

"It can be expensive, especially the licensing costs. However, there is added value in what it can do, not just log aggregation."

"Splunk has always been on the expensive side."

"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."

"The licensing model can be expensive, but the value it provides is significant."
