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.

Correlates incidents, allows for quicker identification and helps prioritize investigations

The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"Log search and alerting/reporting."

"Splunk Enterprise Security is more advanced compared to other solutions, which makes it stand out as a better option."

"Splunk goes beyond collecting basic metrics like CPU or memory utilization; it comprehensively gathers data from various sources, including networks, applications, and virtualization, eliminating the need for siloed solutions and enhancing the capabilities of existing engineering software."

"Overall, Splunk is among the top three SIEM tools due to its capabilities and agility in bridging business analytics with security needs."

"If you are an enterprise and you need the best service for critical business analysis, Splunk would be one of the best choices."

"This is a straightforward solution, easy to configure."

"The most valuable feature is that it brings all of the components necessary to identify, analyze, and respond together."

"I would assess the stability and reliability of Splunk Enterprise Security as typically very good, with minimal downtime or crashes."

More Splunk Enterprise Security pros

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."

"It can integrate with almost any cybersecurity tool available in the market."

Cons

"The difficult part is related to integration with sources of data that are used to create the logs as this depends on the infrastructure of the client."

"To improve Splunk Enterprise Security, I would suggest allowing third-party SOAR solutions to work with it."

"The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex."

"While Splunk Enterprise Security is powerful, it presents significant complexity for users, as it's not particularly user-friendly for beginners."

"There are new services which are coming up. If Splunk can catch up with the speed of Amazon, and with the integration, instead of us waiting for another year or so, that would be good."

"Scalability may become a challenge when deploying Splunk Enterprise Security due to licensing based on ingestion GBs, while cloud-based solutions such as Microsoft Sentinel offer more flexibility without requiring additional infrastructure resources."

"You do need a lot of training and certification with this product."

"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be cumbersome."

More Splunk Enterprise Security cons

"Support is an issue because they have a limited number of resources."

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."

Pricing and Cost Advice

"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."

"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."

"The tool's licensing is good and we haven't received any complaints from the team handling it."

"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."

"Splunk Enterprise Security is expensive."

"Splunk Enterprise Security is not a cheap product, but I think it is worth every dollar that you pay."

"I have no opinion on pricing."

"The licensing costs are high for Splunk Enterprise Security."

"It’s a single license platform."
