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.

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 love Splunk; it is fantastic and our account team is always willing to work with us and make sure we're getting the most for our money."
"Splunk Enterprise Security offers valuable features like seamless integration and a SQL-standard Structured Query Language for easy searching."
"The technical support is among the best in the market."
"The solution's most valuable feature is its data modeling."
"If you want to understand how it can analyze or find out incidents, the visibility is good."
"Splunk Enterprise Security has helped reduce our team's average meantime to resolve metric by about 50 percent because we are able to tune it to lower false positives and noise."
"Splunk Enterprise Security is fully scalable because it provides all kinds of configuration in management servers and all cloud integrations such as AWS, Azure, Google Cloud, Kubernetes, Docker, GitHub, Jenkins, and Cisco as well, and it is quite fully scalable across all platforms."
"It gives us good visibility into multiple environments, including cloud, on-premises, and hybrid; irrespective of platform."
"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."
"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."
"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."
"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."
 

Cons

"While Splunk offers SOAR as a separate product, integrating it into the next version of Splunk Enterprise Security as a unified solution would be beneficial."
"I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team."
"Splunk Enterprise Security has not helped reduce our alert volume."
"The GUI can be improved. Splunk has always suffered from having a kind of goofy UI, it needs some updating."
"Regarding Splunk Enterprise Security improvements, I think there should be licensing flexibility, including cost optimization for larger data volumes."
"Splunk does not build apps. They only go back and validate the apps that somebody has already built. They should have remote consulting support. They have a wonderful solution. They have 24/7 security. Nobody needs to depend on any third party and will therefore just buy Splunk on the cloud."
"The solution could be more user friendly and it's difficult to know at this stage whether our requirements will be met by the solution."
"I would definitely improve the risk-based alerts in Splunk Enterprise Security, helping SOC analysts to get to the drill-down searches."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"The filtering has room for improvement."
"There is always the potential for additional integration and protocol extensions."
"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."
"There is room for improvement in terms of observability."
 

Pricing and Cost Advice

"As a team, we prefer the old pricing model with a perpetual license. We are still evaluating the whole subscription-based model."
"Its pricing model can be improved."
"I believe that Splunk Enterprise Security is worth the price, but it is expensive."
"Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"The price can always be lower, but it is fair at the moment. The cost efficiencies depend on the licensing and how much data we are bringing in. We have a fairly large footprint, so it is cost-effective."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"Splunk is really expensive compared to all the other tools on the market, including Microsoft Sentinel."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
