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

"We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used."
"It gives us the liberty to do more in terms of use cases."
"The investigation feature helps the team seamlessly put everything together, providing a consistent view of all relevant artifacts for incidents."
"Splunk Enterprise Security has helped greatly improve the organization's business resilience."
"Splunk Enterprise Security's risk-based alerting positively impacts my alert volume and analyst productivity because we get low, medium, and high-security alerts based on the use cases driven in Splunk Enterprise Security, and we receive good feedback from clients regarding our productivity as we consistently resolve incidents meeting SLA, resulting in increased client satisfaction with our team and work over the past two to three years."
"Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
"The most valuable aspect of the solution is the dashboard. It's very intuitive."
"The connections to the database are very good and updating the data files is simple to do, and the dashboards are useful and user-friendly."
"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."
"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."
"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."
"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 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

"For on-premise, it's more about optimization. With such a heavy byte scale of data that we are operating on, the search for disparate data sometimes takes about a minute. This is understandable considering the amount of data that we are pumping into it. The only optimization that I recommend is better sharding, when it comes to Splunk, so that data retrieval can be faster."
"Its performance can be better. Sometimes, it takes longer when we do queries."
"We'd like Splunk to reduce false positives."
"The ingestion happens quickly, so you can run up the data costs if you use the default settings. It isn't a problem for government agencies in the Saudi market, but many of the corporations in India are small or medium-sized enterprises that cannot afford that kind of ingestion system."
"Make it easy to use and the cost cheaper. This will help all organisations to implement Splunk."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"It is a hugely complicated product."
"The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."
"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

"Splunk is priced higher than other solutions."
"The pricing of Splunk Enterprise Security is high."
"Pricing and licensing is quite expensive. But for the value the product provides, it seems at par in the market."
"I think the price could be improved."
"It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits."
"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."
"Some of the insights that we have obtained as a part of using Splunk have greatly helped us in increasing our revenue in terms of selling our products."
"It's more expensive than the other tools, but it's worth it. Every penny is worth it."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
